Chapter 1: The Worth Of A Sorcerer
Tokyo, Japan, 11:15 AM
Principal Yaga's Office
The fresh scents of incense and lavender permeated the traditional zen-style office, yet the silence was palpable. The sights of dolls and other decor did make it eerie, had a normal person viewed this room. Yet, the person sitting in front of him wasn't someone ordinary. He is a new student for the school. Recommendation for that matter.
Originally, Principal Yaga was expecting two first years to come in this year's roster. Megumi Fushiguro , sponsored and recommended by Gojo Satoru who also has the Ten Shadows Technique , and the other student from the countryside, Nobara Kugisaki . However, a last-minute call and loads of paperwork later, he received a recommendation and a profile for a third first-year candidate. He couldn't believe the striking resemblance this first-year candidate shared with a staff faculty he received the recommendation and admission paperwork 24 hours ago. Actually, former staff faculty.
An average-height male with light peach skin, blue-tinted silver hair in a slicked-back layered undercut style, and brown eyes stand before him in a professional stance. The male is almost like an exact replica of a very well-known, independent, and greedy Grade 1 Sorcerer when she was younger. Same facial features, the same thin eyebrows, same calm and haughty expression. Now, to put that to the test…
"Sai Sai, correct?" The older male asks him, his expression unreadable and stoic.
"Hai." Was the calm and logical tone of the aforementioned first-year candidate. He can already hear his employer explain to him just how much this recommendation is to provide value for her as a Jujutsu student. At least his little brother admires him like a role model, however abnormal and borderline delusional it can be.
"Answer this question to the best of your ability and with careful consideration: why are you attending Tokyo Jujutsu High?" The bespectacled Principal looks up from his cursed dolls, an indecipherable disposition plastered on his rigid face.
Expectedly, Sai Sai knew Principal Yaga Masamichi. As intellectual and truthful as he is, can be very blunt and dismissive of foolish or selfish ideologies and petty reasons for someone wanting to attend Tokyo Jujutsu High. The pragmatic teenager glanced up slightly, pressing his thin eyebrows together as if he were strategizing a plan. The hand that was on the engraved emblem of his customized Jujutsu uniform was now placed under his chin.
"To be precise, my reasons for attending this school are rooted in a collective sense of duty, a desire to protect the citizens of Japan, and the mission of safeguarding society from curses and curse users." Sai Sai explains diplomatically, his countenance radiating an air of calm and punctual logic. "I have cultivated a profound curiosity and intellect regarding why curses are created, why they hunt us, why they want to cause discord and chaos, their origins, and more efficient methods for exorcising them as a sorcerer."
The last sentence of his words echoed in the dim-lit office, the silent ambiance whispering within the 4 walls. Principal Yaga, composed and indifferent, continues to stare at the silver-haired student dressed in a customized version of the school's uniform. It happened to be a dark blue blazer with three black buttons, a black button-down shirt, a dark blue tie, and slim-fitting dark blue uniform pants. The two pins with the school's crest logo are attached to his blazer's left breast.
Why did he put in such a detailed and unique customization for this uniform?
“Why did you choose this school to hone your skills for Jujutsu Sorcery? A field where your own life maybe at risk at any given time and help save the innocent lives of those who are unaware of the cursed spirits they are surrounded by?” Yaga asked with clear cautiousness and a tone that sounded like a warning.
Because my employer stated I would provide value to her and to the school, as my life is an asset meant to be used for my own gain as well as hers. My life is measured by worth, not by risk. These are the thoughts that Sai Sai states in his mind but he admonishes that from his brain and conjures a more diplomatic and professional response.
“Firstly, the school's reputation for excellence and tradition in teaching Jujutsu Sorcery is unparalleled. The quality of education and training it offers, along with the esteemed instructors, make it an ideal environment to master the necessary skills. Furthermore, the gravity of the responsibilities that come with Jujutsu Sorcery is not lost on me. The potential risks involved are precisely what motivates me to pursue this path diligently. I believe that by mastering these abilities, I can contribute to safeguarding innocent lives from the unseen threats of cursed spirits. The desire to protect and serve is at the core of my choice, and I am committed to upholding the values and ethics that this school promotes.” He clarifies with a calculated and professional tone, eyeing the Principal with a leveled gaze demonstrated with respect and grace. He clears his throat to continue the last part of his explanation. “Ultimately, my decision reflects a deep-seated dedication to becoming a responsible and skilled Jujutsu Sorcerer, prepared to face the challenges and uncertainties of this field with integrity and competence.”
As Yaga absorbed the earnest explanation, a heavy silence descended upon the room, hanging in the air like a shroud. The atmosphere was charged with tension as if every whispered breath could disrupt the delicate equilibrium. The gravity of the conversation had etched itself onto the faces of those present, etching lines of concern and determination.
The world outside seemed to recede, leaving only the faint hum of distant traffic and the muffled rustle of leaves in the breeze. The somber ambiance was palpable, and the weight of the unspoken burdens pressed on those gathered, leaving them locked in silent contemplation of the path that lay ahead.
Yaga eliminated those troublesome thoughts after taking enough consideration of Sai Sai's reasons for attending this school while the latter appears pragmatic and unfazed by such a tense wait. Most students would. Yaga deems his reasons valuable.
"You passed. Your speech is immaculate. I find it quite impressive that you have a prudent and serene mindset at the age of 16. Then again, you have someone who raised you with high standards, yet I am uncertain if they raised you with morals." Yaga responds dutifully. "I hope you stay on the path of your core ideology for the next 4 years here. There are others out there who stray away from their ideologies."
Sai Sai nearly scoffed at the first part of the Principal's verbiage. His employer with morals? Questionable. High standards? Definitely.
"Welcome to Tokyo Metropolitan Technical College. Or colloquially Tokyo Jujutsu Tech." Principal Yaga announces. "As the second first-year student on our campus, you will be with your sensei, along with the other first-year student who arrived here a week ago. All of your personal belongings and items are already inside your dormitory unit."
Sai Sai simply nodded. A pondering thought simmered his mind as he replayed the words of his Principal. He clears his throat softly while maintaining firm eye contact with the burly man.
"Who is the sensei I will be meeting and be mentored under, Yaga-san?" His question was answered when the door behind him slid open abruptly, the sound crackling and echoing in the air and the surrounding walls. Yaga looked behind Sai Sai with a stern glare as this meeting was inappropriately interrupted. A loud, energetic, and obnoxious voice calls out in the once comfortable silence.
"Ohayo Gozaimasu, Yaga-san! I hope I am not disturbing anything important."
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
His employer was right. Gojo Satoru, who happens to be the world's strongest sorcerer, Special Grade status to be concise, is indeed pompous and vexatious. Not only is he the strongest sorcerer, but he happens to be his new sensei.
This will be very entertaining.
"Gojo," Yaga’s voice carried a calm but clearly repressed and irritated tone. "My interview with our new first-year student was still underway. Your lack of decorum is causing a disturbance.” The one time he asks Gojo to be early is unfortunately on such bad timing. Why is this man rebellious against the rules?
“Ah, gomen.” Gojo waves his hand back and forth dismissively, less focused on the meeting and more focused on the new first-year student who still has his back to him. “I wanted to meet the new first year that arrived today. Plus, there is more paperwork for you to look at, courtesy of me.” Gojo strides across the room to hand in the paperwork while carelessly lacking the etiquette of authority. Yaga kept his mouth in a thin line, sighing gruffly through his nose as he glanced down at the small pile of papers.
Sai Sai cranes his neck to scan the Special Grade Sorcerer who will be his sensei this year. He looks at Gojo’s figure, and then the blindfold that happens to be concealing the upper half of his face and his eyesight. From what his older sister explained to him, Gojo’s Six Eyes technique gives him enhanced perception and awareness, making it utterly impossible for someone to outmaneuver him. However, such immense perception comes with a great cost, such as extreme sensitivity and high energy consumption. Hence the clan head of the Gojo clan wears sunglasses and blindfolds to prevent that kind of strain on his eyes and cursed energy.
His serious introspection was disrupted when a large hand waved in front of his face.
“Ohayo deep thinker! What’s got you lost in the labyrinth of your mind today?” Gojo asks with a playful and teasing tone, which many would be annoyed by. Not Sai Sai, however. He’s honed his skills and fortitude that took years to master. It’s even more helpful that he learned that from his employer.
Sai Sai sends him an amused grin, thin eyes full of equanimity and poise. Principal Yaga watches the new first year, impressed that someone isn’t annoyed or put off by Gojo’s energetic and overconfident aura as well as the sorcerer’s carelessness of personal space. Yet, he still watches how this interaction will play out with caution.
“I find solace in the intricate web of ideas, pondering the existence of mysteries.” Sai Sai responds with tranquility, his eyes glinting with mischief and condescension. “You propose dancing in the abyss of uncertainty?”
Gojo, obviously aware of the aloof and impish aura, just smirks wider at Sai Sai’s indifferent and cool words. He finds this very amusing.
“Well kid, dancing in the abyss of uncertainty isn't about recklessness; it's about embracing the beauty of the unknown. It's where we discover new possibilities, push our limits, and find answers to those very mysteries you ponder. The dance isn't about fear; it's about the thrill of the journey.” The blindfold-wearing man expositions with a gleeful grin, ignoring Yaga’s annoyed glare at that response.
“I see, so you are speaking from experience. Your perception sounds mysterious and unhinged.” The silver-haired boy hums in response. Gojo chuckles at the boldness that is Sai Sai. He is surely going to love this kid.
"Oh, you've got a keen eye, Sai Sai. Experience teaches us some of the most interesting lessons, and life should always have a dash of mystery, don't you think?" Gojo chirps with inquiry as he continues to study Sai Sai.
“Mei Mei has told me a wealth of information regarding you sensei. Despite your intellect and immaculate experience, I am a lot more used to my sister’s way of Jujutsu Sorcery. I hope to learn alot from you with experience and tactics.” Sai Sai adds in while still maintaining poise and calm eye contact with Gojo. The Sorcerer smiles at the mention of a fellow Jujutsu Sorcerer, and that Sai Sai is directly related to her.
"Ah, Mei Mei, is always full of surprises, isn't she? Well, Sai Sai, you've got the right attitude. Experience is a wonderful teacher, and I'm here to show you the ropes in my own unique way. We'll make a splendid team, I'm sure of it." Gojo pats Sai Sai’s shoulder with his reply.
“Hmm, I will take your word for it, sensei.” Sai Sai glances from his sensei to Principal Yaga. “Sumimassen, I assume that you wish to share more information regarding the campus?” He inquires.
“I was going to announce the details, but since Gojo is already here, I might as well leverage him to give you a tour around the campus and meet your classmates and upperclassmen. Sadly, our third-year students are currently suspended so it is unfortunate that you won’t be able to meet them.” Yaga clarifies while grabbing the paperwork on the low table. “Welcome to Tokyo Jujutsu Tech, Semi-Grade 1 Sorcerer Sai Sai.”
The silver-haired student bowed before Gojo patted him on the shoulder. “Okay! Why don’t I show you around this large institution and meet your classmates and upperclassmen, shall we?” Gojo asks while walking them both out of Yaga's office.
Once the two of them left, the Principal sighed as he looks at the paperwork again to see what was important. His eyes squint in slight surprise as he reads it over again.
Another first-year student? Kiyoko Yasuragi? She was recommended by Sai Sai?
That surprised the stoic man as a new first-year student recommending another first-year candidate. Let’s see what this student can offer and what are her goals for being in his school.

Tokyo Jujutsu Tech Campus, 11:22 AM
The birds chirping in the air along with the quiet hush of the wind made the scenery tranquil and prosperous in the eyes of Sai Sai. He had seen nature like this before, but only when he was in the countryside doing missions as his employer’s assistant. To see this on the outskirts of Japan’s megapolitan capital is mesmerizing, as he is a city boy at heart. The 36 million people who live within Tokyo’s metropolitan area, are very unaware that nature and biodiversity places like this exist.
“So, Sai Sai-kun, you are a Semi-Grade 1 sorcerer? Quite impressive for a first-year student.” Gojo’s cheery voice breaks Sai Sai out of his peaceful thoughts.
“Hai. I am this rank because, on the Night Of 1000 Parades, I assisted Mei Mei in eliminating four grade 1 curses. Despite not yet being a Jujutsu Sorcerer at that time, I felt like I was one that night.” The silver-haired first-year student explains, running a hand through his hair. “I have trained since childhood on my agility, strength, and skill to get to where I am now. It’s exactly how Mei Mei taught herself to become a formidable Grade 1 Sorcerer.”
“Interesting,” Gojo muses out loud, his hand grasping his chin from such detail, “so you’ve made yourself excel in different ranges of skills. Impressive. Do you have an innate technique as well?”
Before Sai Sai could respond to that question, the sound of footsteps scraping on the stone path made him pause. He glances to his left to see a teenage boy with black spiky hair, light skin with black, stoic eyes, and in the traditional Jujutsu High uniform.
Oh…isn’t this the heir to the Zenin Clan?
“Ah! Megumi-kun, perfect timing!” Gojo cheers while flashing a smile. The spiky-haired teen simply walked forward with an indifferent look. Rather, his attention was piqued at the silver-haired teenager with a corporate-style Jujutsu uniform.
“A new student?” Fushiguro asks in a seemingly aloof fashion. Yet despite that, Fushiguro looked at Sai Sai with intrigued eyes. Was this a recommended first year from a Jujutsu Sorcerer? Or was this individual from a clan of Jujutsu Sorcerers? Then again, judging from the blue-tinted silver-haired teen's uniform and how liberal and customized it is, he didn’t look like he was from a clan.
“Why yes! Megumi-kun, this is Sai Sai! The younger brother of my dearest friend Mei Mei and is a Semi-Grade 1 sorcerer!” Gojo, in typical flair, introduces the Ten-Shadows user to the new first year. The ranking does surprise Fushiguro.
“Semi-Grade 1? The same rank as Inumaki-Senpai?” Sai Sai smiles with amusement at Fushiguro’s bewilderment. But he will not judge him.
“Yes. I am a Semi-Grade 1 rank. The reason behind it is due to me aiding Mei Mei and a few other sorcerers against four Grade 1 curses on the Night of 1000 Parades , which was last year on Christmas Eve.” Sai Sai explains as if it were something he said 1000 times. He isn’t irritated by these kinds of responses since it is logical for most students who are first years and second years to be surprised by a student who is higher than the entry-level ranks, which are Grade 3 or Grade 4. Yet, Okkotsu-Senpai was, and still is a Special Grade Sorcerer when he started as a first-year student so this shouldn’t be that surprising.
“You are Megumi Fushiguro, from what I presume, your innate ability is unique and originates from the Zenin clan: Ten-Shadows ,” The black-haired teenager's face becomes emotionless at that statement. Most likely due to his dislike of the clan, “and you recently became a Grade 2 sorcerer. So congratulations are in order.” Sai Sai replies with a grin. Fushiguro of course, shows a mix of astonishment and slight annoyance, in regards to the fact the teen talks as if he is this haughty yet intellectual person. But deep down, Fushiguro accepts the praise from a new first-year student.
“Ah look at my students, bonding like children.” Gojo muses out. Fushiguro clicks his tongue.
“We are children, idiot.”
“Megumi-kun! So mean and rigid! Lighten up a little.” The Six Eyes user grumbles. He immediately shakes it off and a child-like grin plasters his face. “Anyways! I guess we have some more introductions to do with you to our other students. The Second-Years! Sadly, Yuta-kun is in Africa so we won't be able to introduce you to him personally. Unless I can do a video call with him right now!” Just as Gojo pulls out his phone to call the second year who is abroad, Sai Sai’s phone chimes.
He takes it out and opens his screen. Sai Sai smiles at the latest text message.
“Unfortunately Gojo-sensei, I just received a mission to investigate some strange whispers and noise inside a house in Tateyama, Chiba Prefecture.” Sai Sai states while Fushiguro raises eyebrows over his classmate’s words.
“A mission already? But you’ve just arrived and you haven’t settled in your dorm room.” The spiky-haired teenager replies while Gojo babbles away after reaching Okkotsu on the other line.
“Gomen, but it seems I am the appropriate one for this investigation. My employer is in Fukuoka, so it would be out of her range to fly back to Tokyo. Missions are always first. Pleasantries can come later. I will be back later.” Sai Sai affirms, before walking down the cobblestone path, baffling Fushiguro and making Gojo stumble over his words when his new student leaves.
“Sai Sai-kun, wait! You haven’t met Yuta-kun yet!” Gojo shouts as he waves the phone in the air to alert him. Sai Sai looks back once.
“Gomen Gojo-sensei, but this mission seems to be much more important since it’s in another part of Tokyo Bay. I will be back soon.” Sai Sai intersects, before walking down further, ignoring Gojo’s shouts and pleas.
“Ugh, I thought he wouldn’t be that persistent for a mission.” Gojo groans as Fushiguro just stares at him.
“Gojo-sensei, are you there? All I see is the ground. Who were you trying to introduce me to?” The meek voice of Okkotsu Yuta asks over the phone, alerting the blindfold sensei back to attention.

Tateyama, Chiba Prefecture, Japan
3:00 PM
To think that such transfers would be required from the campus to Tokyo Station would be easy, it wasn’t that simple. Sai Sai had to take the Chuo Line to Tokyo Station, then transfer at Ochanomizu Station to transfer to the Sobu Line for a quicker route to Chiba. Sai Sai may have been born in Tokyo, but he never rode the subway or any of the JR railway lines except the Shinkansen. He was always chauffeured, courtesy of Mei Mei with being loaded after becoming a Grade 1 sorcerer.
After riding the Sobu Line to Chiba Station which is the last stop, he arrives just in time to miss the next train going to Tateyama. Deciding on another route, he hailed a taxi outside Chiba Station. He can afford a 2 to 3-hour ride from Chiba to Tateyama, he owns a black card and has a wad of cash after all.
After a calm and serene ride from the bustling hub of Mihama Ward to the peaceful and traditional parts of the prefecture, he sees the coastal town of Tateyama along with the town’s historic castle. He paid the cab driver 4,000 yen for the ride, (seriously chump change to the Semi-Grade 1 sorcerer) before stepping out and feeling the June summer breeze flowing within the atmosphere. He can feel and see small level curses strolling by in the air, wiggling and hovering by, most of them echoing and murmuring “lonely” or “gloomy”. As he glances at his cellphone and looks at the GPS of where the mission is located, he begins strolling down the path to where the house is, which is ironically where many of these gloomy curses are coming from.
So this curse must have lived a life of depression, anger, sadness, and loneliness. All negative feelings, which lead to the birth of a curse based on those dark emotions.
Sai Sai passes by rows of Machiyo-styled houses to his destination, each being housed by a resident, family, or an Izakaya of a particular delicacy. As these people focus on their daily activities and lives, they remain unaware of the malevolent and vile spiritual entities that threaten them everyday. Even more so if they produce negative energy with negative emotions, birthing a curse they aren’t even aware they made. The closer he gets to the destination, the stronger he feels the dark cursed energy flowing in the air.
Just as he is by the GPS, he feels the waves of cursed energy flowing beside him, in front of a Nagaya-style house. The entire property leaked with immense dark cursed energy and numerous curses, all muttering and eerily groaning “lonely”, “melancholy”, “what era is it”, “how long have I been alone”.
“Here. Judging by this part of town and how abandoned this place is, everyone strays as far away as possible.” Sai Sai deduces, glancing at a sign that says Property Abandoned. DO NOT ENTER. As if he would listen to ordinary regulations. His phone rings and he sees the caller ID.
Ijichi Kiyotaka
The Supervisor Manager for Jujutsu Sorcerers, who also aids students from school on missions to provide curtains, only allows Jujutsu Sorcerers present. He is surprised that the individual isn’t here at the cursed location since all supervisor managers arrive before the Jujutsu Sorcerers do. Sai Sai answers the call.
“Konnichiwa, Ijichi-san?”
“Ah good. I was hoping you would answer considering you are on your way to the mission?” Ijichi asks on the other line, a slight anxiousness in his tone.
“I am already present at the location.” Sai Sai replies, observing the area around him with precision and caution.
“O-Oh, already!?” Ijchi stutters in shock. Sai Sai lets out a wicked smile at the male’s revelation since he wouldn’t be able to see it. Ijichi clears his throat from a trembling voice, becoming professional. “Well in that case, let us get down to the debriefing. 3 years ago, the house was once owned by the Kodoku family. A merchant family that did all sorts of small-time trade and logistics within Tateyama. However, a series of bad tragedies followed one by one. The three children of the Kodoku family were caught in a car accident during a storm while they were out doing chores. The younger two children died, while the eldest remained in a vegetative state. The mother, filled with grief and depression over the loss of two of her children, died of a broken heart. Lastly, when the eldest child died after being on life support for 6 months with no recovery, the father committed suicide 28 days later.” Ijichi debriefs to the blue-tinted silver-haired first-year. Sai Sai hums in thought at this information, before applying logic.
“Implies the fact that the surname ‘Kodoku’ means lonely, this must have caused some past conflicts resulting from bad luck in the past. Since Japanese children carry the last name of their father through patrilineal lineage, they were given the bad luck of depression and loneliness. With such tragedies happening one after another, the feelings of grief, anger, depression, and loneliness began to thrive within the humans’ souls, and that releases multiple curses that share the same dark aura.” Sai Sai hypothesizes regarding the surname.
“I haven’t looked up past conflicts regarding what happened to the father, whose name was Kodoku Shitsubou. Other than dropping out of high school when he was 17 and was part of a street gang for 5 years, he once had a major alcohol problem.” The male on the other line responds evidently.
“I see. ‘Shitsubou’ means disappointment. This could relate to the fact that said male failed primary education, then became a disappointment to the family. His name already means that particular definition in Kanji, which could have also meant that he was born as a disappointment to the family even before he dropped out. This resulted in him already being born with negative energy due to his name, with the tragedies being the icing on the cake for him. What a pity.” Sai Sai muses out while seeing a curse wiggling it’s way in the desolate shoji.
“Also,” Sai Sai pauses as Ijichi’s tone becomes grim, “It shows small evidence that the father had abusive tendencies, but since no one made a report to child services, they were ignored by neighbors and residents within the vicinity.”
“Then that explains why anger and rage are present within the cursed aura as well. That then leads me to conclude that the curse could be Grade 2 with all of the negativity manifested as the years passed by, Semi-Grade 1 at most. The other curses I sense in there are much lower, all being Grade 3 or Grade 4.” Sai Sai answers, taking out his cursed tools which are closed, each concealing mini tanto blades within the black feathers with only the sharp tips of silver being shown. “But if that strong curse is in the way, then I wouldn’t have any playtime with the weak curses.” The blue-tinted silver-haired teenager’s words make the male on the line choke.
“P-Playtime? Sai Sai-san, curses shouldn’t be underestimated regardless of how low their ranks are. Each curse can have unique abilities or intelligence of their own. Sometimes weak curses can imply cruel tactics that can psychologically shift your own strategies, such as a curse taking a hostage.” The glasses-wearing male cautions.
“I am very aware of what curses can do and what they are capable of. Yet sometimes, mocking them to a place with skill and strength can be entertaining when they are aware they have nowhere to run or nowhere to defend themselves with.” Sai Sai sighs out.
“Even so, mocking weak curses is not a good thing to do when your life could be at risk.” Ijichi chastises.
That’s not the case when you have an older sister who ingrained into your head “Would you die for me”? As part of a binding vow you’ve once had with her until she saw productive potential in you when you were 13. Even if me and her no longer have that binding vow, my life is measured by worth, not by risk.
“Fine. I will proceed with caution. But I will make this mission quick since I haven’t gotten the chance to settle in my dorm at campus yet. If it proves to be more than a challenge, I will utilize my innate ability to end it instantly.” Sai Sai states, easing Ijichi. Despite the soothing tone, the older male on the other line did feel apprehensive about the teenager’s poise declaration. How can a first-year student be this unperturbed, steadfast, and placid on his first mission?
“Please be very careful. I will be there shortly to oversee the mission. I am on the Uchibo Line heading to Tateyama.” Ijichi notifies, clearing his throat. “The only issue is since I am not at the designated location, there is no veil to cover the house.”
“No worries, Ijichi-san. I may not be a Window, but I know how to set up a veil curtain. I was interested in how they were formed so I studied books and scrolls about this type of Jujutsu and learned it myself.” Sai Sai steps closer to the house. This surprises the supervisor manager as if this student couldn’t be more talented.
“Then I guess you can proceed with the mission. But Sai Sai-san, be careful.” Was the last reply of Ijichi before Sai Sai bid farewell and ended the call. He puts his right hand up with both his index finger and middle finger upwards in a sort of cast.
“Emerge from the darkness, blacker than darkness.” Sai Sai chants. Suddenly the sky surrounding the house and himself darkens into a midnight shade, creating a barrier in order for humans to stay clear of this location and for the first-year student to lock in the curses. The last thing he wanted was a commotion, not to mention this house might end up in ruins since the entire property is a shelter for a small group of curses inside. With a confident smirk, he heads toward the Nagaya-styled house and walks up to the wooden porch.
He was about to touch the door but paused. He thought of different scenarios of sliding the shoji open. What if one of the curses has some sort of ability that can poison the door or use strategic movements that can lead to a trap? Better yet, what if the curses felt his presence and they organized an ambush to pulverize him the moment he opened the door? He may love to mock and toy with weak or insufficient curses, but he is not one to go in without a set of tactics. Plus, he did feel malevolent cursed energy within the door, which hints at the pending danger of him just simply entering. Not to mention the shadowy cast behind the filthy translucent paper in the latticework frames. Therefore, a sleek and vicious entrance is necessary. Sai Sai’s smirk widens in pure glee.
“Time for Yatagarasu to be used for this particular method.” The first-year mutters impishly.
With a fluid flick of his wrist, Sai Sai gracefully unfurled his right tessen fan, it’s midnight black feathers rustling softly with a series of spine-tingling crisp, metallic snaps emitting through the air like the sibilant hiss of a serpent imbued with cursed energy. Suddenly, Sai Sai unleashes quick but sleek and fierce strikes, slicing the fragile bamboo and grimy white paper. The bamboo on the shoji, aged and dilapidated, let out agonizing creaks and splintering snaps along with the ripping of the paper as the sound was akin to shattering glass.
Amidst the impending chaos and cacophony of noises, the deadly weapon released a sinister duet with the shoji’s ultimate demise. The grisly sound of flesh and purple blood yields to the relentless onslaught commenced by Sai Sai. Each consecutive strike of the tessen fan guided by an eerie precision, created a gruesome melody of harrowing screeches, tearing, and squelching of the curse sounding like a rending of fabric soaked in a viscous liquid. The visceral and guttural sound echoed within the macabre symphony of destruction.
A series of painful cries etched out and a thud in the tatami mats of the genkan was heard. Satisfied, Sai Sai spins in a counter-clockwise motion, pivoting himself on his right foot while his left leg ascends in tandem. At the zenith of his spin, he sends a powerful kick to the bottom half of the shattered door, breaking apart the last barrier to the house. The smoke and dust rose from the ground and door into the air, but Sai Sai wasn’t deterred as he entered the house into the genkan, where he saw the fatally wounded curse dispersing into nothingness, leaving behind purple blood in it’s demise.
“Hmm…I wonder where that stronger curse is. Based on the brutal slaughtering I committed against that exorcised curse, it felt like a Grade 3 curse. But now that I am inside the property, I sense a strong curse in here. Between the ranks of Grade 2 and Semi-Grade 1.” Sai Sai comments brazenly. He observes his surroundings and witnesses two more curses hiding in the ceiling behind the living room. He pretends to not see them, letting the dark entities assume he is underestimating them. “I wonder where that strong one is…is it being a coward hiding from me? Did it bear witness to my murderous onslaught of it’s accomplice? Oh, the joy.”
Sai Sai's haughty persona exuded an air of effortless confidence as he strolled through the desolate house. His ebony Santoni dress shoes, polished to a mirror-like shine, echoed with an aristocratic click and clack against the ancient tatami flooring. The dissonance of opulence in the midst of desolation was a hallmark of his audacious presence.
With a smug chuckle that spoke of utter disdain for the curses lurking in the shadows, Sai Sai proceeded with calculated caution. He savored every step, reveling in his own perceived invincibility.
"I could have sensed there were more curses in this house, yet I don't sense a whisper of their presence." He mused, his voice dripping with feigned confusion. His words were a weapon, skillfully wielded to psychologically torment and irritate the curses, luring them deeper into his intricate trap. He continued, a sardonic grin playing at the corners of his lips.
"Perhaps they witnessed the bloody massacre of their kin and, in their pitiful fear, fled for their nonexistent lives. How disappointing; I thought curses were made of sterner stuff, much more determined in their futile attempts to take down a sorcerer." His every syllable was a calculated strike, designed to lure the curses into his web of domination, where he could systematically dismantle their threats with his cunning and arrogance.
Sai Sai's indifference and haughtiness resonated through the house as he continued to goad the curses with his harsh and contemptuous words. With an apathetic shrug of his shoulders, he sneered, "Did they truly need to vanish into the shadows? Are they nothing but a congregation of spineless cowards, unworthy of my attention?"
He paused for a moment, his voice dripping with disdain as he let his words linger in the oppressive air. The curses, lurking in the periphery, could feel the weight of his dominance. But he knew it was working because he was feeling the rage of the curses increasing word by word.
"Of course, it all comes down to the Kodoku surname, doesn't it?" Sai Sai taunted, his tone conveying that the name itself was beneath him. "A name that means 'lonely,' a fitting moniker for a family cursed from the very start. It's no surprise they spawned these curses, cursed themselves by their own inadequacies and the glaring failure of their patriarch."
As he spoke, he reveled in the power his words held, knowing that his arrogant and derogatory remarks further cemented his dominion over the curses. He was a master of manipulation, using both his magical abilities and his condescending language to push the curses into a corner from which there was no escape.
“A failure of a father who was a deadbeat and good-for-nothing coward-” At that last sentence, the curses that were in hiding screeched in anger, letting out hollow and eerie words.
“Do not talk about Ota-san ~”
“Tell me… do you know the meaning of loneliness…”
“We are sorry, ota-san…stop hitting us…please…please…PLEASE…PLEASE…”
The curses ominously advanced toward him, Sai Sai's smug smirk grew, relishing the suspenseful climax of his intricate plan. With calculated precision, he raised his left tessen fan, extending it like a blade of darkness ready to strike. The anticipation hung heavy in the air, the curses closing in with malevolent intent.
His right tessen fan, suspended in the air like a poised serpent, was an embodiment of lethal potential. With a fluid motion, he flexed the fan again, its metal ribs whispering through the tension-filled silence. Each rib unwound like a coiled spring, releasing a disconcerting symphony of ominous echoes that reverberated through the desolate room.
The first curse leaped towards him with a ferocious strike. The curse, with a grayish and greenish body identical to that of a centipede, with hundreds of eyes in it’s head and face, erratically aimed to land on Sai Sai. But such a task was futile. Sai Sai sidestepped swiftly, the curse missing his shoulder, making it vulnerable to Sai Sai’s tessen fans. As expected, Sai Sai slashes the curse immediately through the curse’s midsection, it’s body bisected into two as the unfortunate curse cries in pain. Sai Sai enjoyed hearing the curse’s anguish as the spirit fell to the floor with it’s blood splattering on the tatami. But he didn’t have time to revel in his cruel machinations when he slices the incoming curse from beside him with his left tessen fan by spinning himself toward the being to demolish it. Then he sees a small horde of weak curses coming straight at him after obliterating the second curse spirit that met it’s demise. With the grace of a predatory feline, Sai Sai aims Yatagarasu at the curses with unadulterated sadistic glee.
“Bring it, you cockroaches.”
In mere milliseconds, the living room was transformed into an arena of chaos. Sai Sai moved with a grace that defied the intensity of the battle that raged around him. His every action was a calculated and strategic dance of destruction.
As the cursed spirits closed in, Sai Sai's tessen fans became an extension of his will, slicing through the air with fierce elegance. The sharp, harmonious sound of metal and wood meeting flesh reverberated through the room, a symphony of lethal fidelity that combined with the grotesque and plopping sounds of flesh and blood, splattering throughout the destroyed room.
The cacophony of cries, wails, and groans intertwined with the elegant strikes, a haunting chorus of vanquished spirits. Each of Sai Sai's dodges was a work of art, a testament to his uncanny agility and foresight. He moved with the fluidity of a shadow, a wraith evading the grasp of the damned.
In a relentless barrage of attacks, he dispatched his foes one by one, an affirmation of his mastery. The room bore witness to his prowess, an intricate ballet of life and death. Sai Sai's calculated and intense assaults were a testament to his skill, a dance of grace and destruction that left the cursed spirits in disarray.
His dilated eyes, full of hyperactive energy, flickered left and right to the incoming curses who dared to take his life. But Sai Sai extended his fans outward, with his arms outstretched forming a T, before uttering a command to his cursed tool as he poured cursed energy into them.
“Unbind like a typhoon.” The blue-tinted silver-haired teen became a living cyclone within the confined space of the living room. His entire figure spun with an otherworldly elegance, a whirlwind of energy and destruction that was ignited by the infernal dance of Yatagarasu, the cursed tessen fans. The room trembled under the weight of the impending chaos.
As Sai Sai's graceful form twisted and spiraled, a tempestuous maelstrom took shape formed by the powerful cursed weapons. It was a vortex of malevolence and supernatural force, a whirlwind of dark energy that defied the laws of nature. The curses, like hapless debris caught in the gravitational pull of a colossal vacuum, were drawn helplessly into the heart of the storm along with pieces of the tatami, bamboo, and useless house items.
Within the swirling pandemonium, they were at Sai Sai's mercy, their wails and shrieks blending with the furious wind. But instead of being cast aside, the curses were forced into an involuntary ballet. They orbited Sai Sai, a sinister and destructive waltz dictated by the whims of their sorcerer captor. Each revolution of the cursed tempest left a trail of devastation in its wake.
The living room bore witness to the unrelenting might of Sai Sai and Yatagarasu, a partnership of chaos and control. The curses, ensnared in this cataclysmic vortex, could do naught but succumb to the destructive forces that circled them. It was a spectacle of dark majesty, a testament to Sai Sai's mastery over his cursed tools and the catastrophic beauty of their symbiotic dance.
The crescendo of chaos reached its zenith as he, the epitome of calculated destruction, brought the tempest to a sudden halt with the rhythmic click of his shoes against the floor. The room, once a swirling vortex of malevolence, was plunged into an eerie silence as the cyclone of curses hung suspended in midair.
In the eye of the storm, Sai Sai became a living legend of devastation. He launched a vicious ballet of slices and strikes, a symphony of precision and brutality. Each movement was a masterstroke, a calculated blow that rents through the air with a deadly elegance. The obsidian feathers of his tessen fans shimmered like ebony blades, leaving trails of dark energy in their wake as they slashed through the suspended curses. The room echoed with the clang of metal against ethereal flesh, a symphony of vengeance that resounded with each stroke. The curses, caught mid-flight, were helpless against the onslaught of his cursed tools as their cries, gasps, and screeches were mixed with sopping, gurgling sounds of tissue and blood ripping and sprinkling everywhere.
As the last of the curses crumbled into nothingness once they hit the destroyed floor, Sai Sai slid forward on one knee, his hands extended outward, weapons held with a sense of finality. The room bore witness to his victorious stance, a tableau of dominance and control. He had harnessed the destructive forces that had threatened him and bent them to his will.
The room, once a battleground of malevolence, now lay in stillness. At that moment, he was the unchallenged conductor of the orchestra of chaos, and his final set of strikes had brought an end to the tempest, leaving only the echoes of their destructive dance in the air.
He let’s out a pleasant sigh, standing up before flexing his tessen fans of purple blood from it’s tanto blades. He glances behind him in the process to admire the tremendous destruction he caused, there were two large holes caused by his devastating gales: one in the floor and one through the wooden roof. Along with that was the living room, now transformed into a mountain pile of destroyed furniture, flooring, paintings, and other miscellaneous items.
His once sleek and stylish hair, now disheveled and covering his eyes, is slicked back by his hand while he sighs out in contentment. “Coup De Grace.”
Yet, the battle wasn’t over. There was that final curse he has still yet to see. Speak of the Devil and he shall come.
The moment those thoughts played in his mind, he felt the powerful cursed energy from beneath him coming at full speed. With quick thinking, he dodges to the left just in time before a fist suddenly breaks through the last of the tatami where Sai Sai was once standing. A vicious and grim roar echoed the entire house as the vile curse made it’s appearance before the first-year student. Sai Sai faced it head-on with the very same, unadulterated sadistic glee.
However, with such speed, the curse launched a cursed punch at Sai Sai. The teenager put his tessen fans side-by-side to cover his face and form a barrier. Despite that protection and sharp-wittedness plan, the colossal curse delivered a bone-shattering blow, sending Sai Sai hurtling through the wall with a thunderous crash. He catapulted into the heart of the ancient Zen kitchen, crashing violently onto the weathered chabudai, its timeworn wood groaning in protest under the force of impact.
Hence the impact and near-lethal catapult, the blue-tinted silver-haired teenager remained unscathed and unharmed thanks to Yatagarasu’s barrier. He stands up lazily, patting off his uniform of dust, splinters, and porcelain. Disregarding the menacing approach of the curse and its bitter growl, he emitted a tsk of annoyance, his eyes narrowing at the small but conspicuous tear in his left sleeve, the fabric jutting out in an irregular, gaping maw.
“You insignificant, miscreant cockroach. You ruined the sleeve of my customized blazer.” He calls out to the eyeless gorilla-like curse, with purple and blue skin, and a capacious mouth that expanded over the entire face. The being stepped closer, attempting to intimidate the first-year sorcerer. It was to no avail as Sai Sai’s demeanor became serious. “You will be paying for my blazer in your own blood.”
The curse roared violently as it reeled back to throw another powerful punch and swung it towards Sai Sai. This time, he simply sidesteps it as the curse’s fist makes contact with the cabinet. The shattering of jars, tea sets, and rusted cans paled in comparison to the painful screeching of the spirit as the teenager swiftly sliced off the curse’s arm, it’s purple matter painting the dirtied floor. It stumbled back as Sai Sai flexed his tessen fans, a dark look plastered over his face.
“You deserve a gruesome brutality for your actions. I have waited mere minutes for you to show up, yet you waltz in like a coward after I obliterated your weaker kin that I wanted to save for playing. For wasting my time and damaging my blazer, you will succumb into the depths of Jigoku as I paint this entire house with your innards.” Sai Sai ruthlessly declares as he steps forward at a menacing pace. His eyes abruptly glint with interest when he watches the gorilla-like curse’s arm heal slowly but meticulously. The flesh mounting and forming into each other to regain it’s lost arm.
Hmm…this cockroach has an innate ability of it’s own. Regenerative healing. This means that my slashes, stabs, and slices against this filthy vermin would only render it to activate it’s healing ability to keep it steady. Sai Sai ponders with intrigue, watching the curse’s arm almost heal as the first two fingers are forming.
This means if it’s innate ability focuses on healing it’s limbs, and exterior parts of the body, then it’s internal organs would be it’s weak spots. The vitals and organs cannot heal if sliced through. Therefore, aiming for it’s head and brain will end this cockroach. Yet, based on it’s cursed energy and strength, it will be a battle of wills. This cockroach is indeed a Semi-Grade 1 rank. The same rank as me.
Sai Sai finishes strategizing just as the curse regains his arms and goes into an aggressive stance, ready to pounce. The last tea cup falls to the ground, shattering upon impact, just as the two of them simultaneously propelled forward. The sounds of fists and fans smacking against each other, Sai Sai and the curse traded blow for blow. The air crackled with tension as their deadly dance commenced.
With a flash of accuracy, the curse lunged, its twisted form launching a series of grotesque attacks. Sai Sai, the embodiment of grace and finesse, elegantly sidestepped the frenzied onslaught. His movements were poetry in motion, a hypnotic display of agility and control.
As the curse's razor-sharp claws and venomous fangs descended, Sai Sai's tessen fans sprang to life. They became a whirlwind of ebony feathers and cursed metal, a tempest of retribution. With deft and deadly accuracy, Sai Sai sliced through the curse's limbs and body, leaving trails of ethereal blood in their wake. Despite them healing back, Sai Sai gave no room for sparing them as he continued his murderous onslaught.
Each parry and counterattack was a masterpiece of combat, an indication to his unyielding skill. The room echoed with the clash of metal, the curses' agonized wails, and Sai Sai's calm pants. He was the puppeteer of this deadly ballet, manipulating the curse with calculated poise.
In a final act of defiance, Sai Sai somersaulted through the air, his tessen fans concealed before he stabbed them both in the head. The curse shrieks loudly in pain, gripping the sharp cursed tools out of his head. But it was all for naught. Sai Sai, imbuing his cursed energy with Yatagarasu’s cursed energy, unleashes the tessen fans, the disgusting squelches of blood and flesh being opened apart by the metallic hissing of the cursed weapons entrenched into the curse’s brain.
The vile entity stilled, arms dropping to it’s sides signifying it’s death. Sai Sai pulls his fans out of the being’s head. But he imbues his cursed energy into the tessen fans, combining it with the tools’ own energy and the fans launched themselves at the sides of the dead cursed spirit before levitating it in the air. The cursed tools then kept it suspended in mid-air, one fan propelling on the top and the other one propelling on the bottom like helicopter blades.
With a gestured command of both of his hands going in a crushing motion, the fans on horizontal sides ruthlessly and brutally chopped off the curses’ body parts piece by piece while it was vanishing into thin air. The pattering of blood spraying everywhere unfazed Sai Sai as he committed the final act. The fans completely minced the curse apart until it destroyed the heart, then the fans levitated themselves back into Sai Sai’s hands elegantly.
“Dead for a Ducat.” He mocks at the bloody vacant space, sliding his disheveled hair back with his hands, panting lightly after a catastrophic battle. A battle he won victoriously and completed the mission.
He takes out his cellphone and begins walking out of the destroyed home. But before he can step down to the cobblestone path and send a text to Ijichi, two pair of footsteps appear in front of Sai Sai, entering the veil. He glances up to see the aforementioned male in a surprised state, as well as the famous and cocky blindfold-wearing Sorcerer beside the supervising manager, with an amused grin.
“Well, well Sai Sai-kun It looked like you just made that Semi-Grade 1 curse a Semi-Grade 0, didn't you? You are a strong one indeed.”

So...what did you guys think? Of the story? Of Sai Sai? In general? What is his innate ability? It actually doesn't have to do with the cursed tessen fans either...
What is going on in that collective labyrinth mind of the first-year student? Wait for more writing and chapter of A Nexus's Peril
