Part 1: Here ♡

Part 2: (More Yandere stuff. Nun too crazy)

The Heavenly Hashira. That was you title. You were known for your Aerokinesis, tessen abilities. You weren't the strongest nor the weakest, but you could hold yourself astoundingly well compared to the others. There was no denying that the Heavenly Hashira had quite a few deaths of demons on her hands.

The walk through the dark night was silent. A cool and Icy breeze began to pick up, you shivered.. It felt familiar but you just couldn't put your finger on it.

That was until you heard..That voice. "Don't you know its dangerous for a gorgeous woman to be walking around at night...Alone?" You stop in your tracks, eyes scanning the area in attempt to find where he was hiding. Nowhere in your eyesight, meaning he had to be somewhere behind you.

You take a deep, concentrated breath.. Springing into the air, looking below you. Rest assured there he was. Large muscular build, platinum blonde hair—Leaning up against a tree, waving at you, those cold rainbow eyes smile at you.

With your Tessen in hand, You whisper a quick chant before whisking your arm around. Shooting a atmospheric gas in the form of a small cyclone.

The last thing you wanted to do was create a large one and lose control of it. Once the cyclone reaches the demon it combusts.

You gently land, one foot touching the ground before the other. Your eyes glued on the now clouded area due to the combustible cyclone you sent towards him.

To no avail, no damage was done. Of course what would one expect from one of the most dangerous demons. He walked out of the cloud unscathed, still with that apathetic smile on his face.

"Well..Good evening to you too. Y/n", He spoke."

The air getting colder by the minute, amost like tiny miniscule icicles formed in the air. Breathing in was starting to hurt, causing you to breathe more conservatively. "I'm not here to hurt you, Y/n, Let's just chat for a moment", he cooed.

"Talk? I have no desire to speak with you." He lowers his voice, somewhat husky now. Those symbols within his eyes studying you.

"Playing 'hard to get' I see. You're So cold-hearted Y/n.." He smiled, eyebrows following helping him display a flirty expression as he continued pacing forward.

Of course, you walk backwards not wanting to come into contact with him. The ground started to crawl, a force growing quickly at Douma's feet and working their way towards you. Vines created by Ice, growing.

"Just let me say a few things and I'll consider letting you go for a bit.."

"Huh? Letting me—"

The vines shaped into large lotuses, the icy vines capturing you by your wrists. The vines, growing spikes rushing towards you. In a panic, you wave your fans around. Doused in pink aura, your wind slices the Ice lotus. Your wrists now free you turn and leap, hoping to get out the range of the Ice limbs Douma was creating.

Taking your tessen you use them to your advantage, utilizing its ability to give you a jump boost. Not long after the cold air picks up once more. Seeing Douma chase after you swiftly. Chanting then waving your Tessen as you hopped tree branch from tree branch.

"I advise you to Stop Y/n, I promise I won't hurt you", He says evily chuckling. Creating cyclones, tornadoes of all sorts- taking advantage of the freezing clouds Douma was producing. Sending hurricanes of sharpened Icicles right back at him. The frozen mist slowly engulfing you from behind, as you raced back to the others hoping you could lure him back to the others.

Dodging large wintery icicle shards that plummet from above. 'There! The Estate!' It was just at your fingertips, and then...Dragged down from the sky by Lotus vines. "Y/n, I love a good chase...but I really must confess something."

The vines tossing you around, one minute you hang upside down, the next you're thrown and caught upright. The vines wrapped around your waist vigorously. Holding you still for the deadly demon before you.

Pushing away at the vines, only for them to nearly squeeze you to death as a punishment.

"Release me!", you shout. You wriggle your wrist, striving to create some sort of wave strong enough to break the vines.

Douma, appearing so suddenly right in front of you. Face to Face, His hands latching onto your wrists, keeping them at a halt. His long blue nails, grazing your skin— He snatches the Tessen away from you.

"Fun game Y/n.. I thank you, I needed that run."

You stayed quiet, thinking of the things you'd never done yet..preparing yourself to be consumed.

"I wanted to tell you before— seems like..I've come to fancy you."

"...What?" You're neck nearly snapping as you turn to look at the demon. You studied his face, waiting for him to say he was joking of some sort. "You?...You heartless, unemotional psycho- Are you really capable of such emotions? Don't make me laugh", you scoffed. Douma's usual casual smile drops..

"Heartless..Unemotional?..How saddening you've been convinced I have no feelings..However–" ,With your Metal Fans Douma had taken from you, he closes them before bringing them up to your chin. Gently, lifting up your chin to look at him. "Explain to me what these feelings are..I don't think a emotionless being would feel what I am feeling right now."

"That doesn't change the fact the you're psycho-"

Douma gazes at you, his rainbow eyes undressing you in the process. His smile ever so alluring, baring his sharp fangs. "Psycho, I guess so. I'm a psycho for you."

Noticing that you were slowly moving backwards, now with your back to a tree, icy vines that held you captive loosen, not quite unwinding from you. In an instant, pale fingers intertwine with yours. Caging you to the tree. "Join me Y/n, I'll make you happy."

You shocked by his sudden proposal, pulling at your restraints and his hands. "NO!" Wriggling one hand free, you reach behind you grabbing a spare hidden weapon you carried just incase of an emergency. A blade, now shoved through Douma's skull from his chin and up. Warm crimson staining your hand as it drizzles down. Catching him completely by surprise, his eyes widened with shock.

His hand, swiftly yanking out the weapon out of his face. Blood following the weapon once disguarded. Slightly regretting your actions as you watched him turn his attention back to you. Expecting for your life to be cut short then and there, the opposite happened.

His pale hands, blue claws pinning your free hand to the tree. His eyes sparkled in amazement, desplaying admiration for you. "Oh my, such a beautiful and clean piercing."

He leans in, leaning in close to your face. "You really are something. An slayer capturing my heart..how interesting."

"You're not fooling me, let me go or kill me!"

"The last thing I'd want to do Is fool you, let alone kill you", he cooes. The Demon gazing at your lips every now and then, allowing you to catch onto what he wanted. You turned your head away from him. Leaving Douma chuckling, his fangs once again flashing. "Well..That will come in due time." His multicolored eyes scan you,"Hmm..how about you come with me?"

"What?", you question.

"You heard me, I'm. Taking. You. With. Me!" He sings happily.

..'This guy is really insane you through to yourself.' Douma chuckles, holding the fan before you. He opens it, puckering his lips and blowing icy dust into your face.

"As if id go with you willingly–"

Your sentence discontinued by the substance introduced to your lungs. You wheeze with disgust, in attempt to cough up what you ingested. The swiftness of your limbs going numb, followed by sleepiness now taking control.

Douma smiles joyfully as you slouch against the tree now keeping you up. His vines now releasing you as you fall before him. "I do have to admit, while I absolutely adore you fired up..This, Sleepiness suits you well too Love."

Douma kneels down to your level, reaching out to you. He loops one arm around your back and the other below your knees— carrying you Bridal style.

"Stop..l-let me go", your voice sleepily slurred.

"Mm-mm, the both of us have things to discuss. Take a nap in the meantime, okay?" His smile, the last thing your eyes saw before quickly succumbing to the slumber spell placed upon you.

Practically skipping with you in arms Douma heads back to his Resort. The satisfying sound crunching of dead leaves under his feet follow him.

"Don't worry Y/n..You'll come to terms with my feelings— No matter how long it takes. I will make you mine."

Do I Have OCs For My Half-Demon! Tanjiro AU? You Bet!

Unfortunately I don’t have many drawings of them so I’ll have to describe them. (I’m sorry I’m terrible at drawing!)

Kerido (A Friendly Demon)

Art done by @kurumi-igarashi

Kerido is the definition of a sunshine character. He’s incredibly happy and optimistic despite being a demon.

He has the traits of a manticore (that also applies to his Blood Demon Art). Kerido has the dark purple tail of a scorpion, the black and purple wings of a dragon, and the paws of a lion. Kerido also has long, black, wild hair and black eyes with blue pupils (kinda like Kaigaku). He has a pretty muscular body, but he has a soft belly. Kerido’s most notable feature is the right side of his face. The left side looks normal and pretty, but the right side is heavily scarred. It looks like someone took a cheese grader to his face. He ended up getting that scar in a carriage accident when he was a human child. He’s really insecure about it since it grosses people out when he’s eating or drinking. Kerido usually wears a black kimono with purple lightning and black pants.

Now for his role in the story! Kerido is actually Gyutaro’s boyfriend! Gyu accidentally found him one night in the forest. Kerido was just minding his business and humming. Originally, Gyutaro couldn’t believe that someone could be so happy despite going through so much, but he quickly warmed up to him. Kerido’s happiness is contagious

Kerido ended up flying across Tokyo with Gyutaro on his back. He’s got a massive wingspan, so it was easy. Gyutaro was instantly charmed by the manticore demon.

And well..they just hit it off from there! They’re pretty much the body positivity couple. Kerido makes Gyutaro feel better about himself and his body while Gyutaro makes Kerido feel better about his scar and belly.

Kerido constantly encourages everyone around him. He just can’t help it! However, when it comes to sexual things, Kerido can be really dense. It’s just one of the faults of having a sunshine boyfriend. Zenitsu has the same problem with Tanjiro.

Strifles (The Child Demon)

My baby boy, Strifles is a little child demon. He used to live with his abusive older brother before he was rescued by Tanjiro, Daki and Gyutaro.

Strifles is a hybrid of a demon and a humanoid (more on them later). He has short, messy, black hair and the same eyes as Kerido. He also has cat like paws and a black and blue cat tail. He usually wears an oversized navy blue kimono and black pants.

Strifles also has an undead Maine Coon cat named Nibbles. He was able to summon the kitty using his Blood Demon Art. His older brother has it too, but on a much stronger level. Remember my Gyutaro fic, The Friendly Beast? Well Strifles’s older brother is the jaguar demon!

Basically, Strifles bumped into Daki and Gyutaro and begged them to save him from his brother. They were confused at first until they saw the his older brother was trying to eat him! They had to fight a whole army of undead jaguars, summoned by his older brother, but they couldn’t do it alone.

Tanjiro, Kokushibo, Douma, and Inosuke showed up to help. They also became overwhelmed by the jaguars (and my third OC), but Tanjiro ended getting so pissed off by the abuse that Strifles was going through that he burned all the jaguars and the older brother with his sun breathing

Strifles now lives with the other demons. He very shy and quiet, but he very sweet and always tries to help. He’s best friends with Rui and he’s pretty much glued to Gyutaro’s side. He also loves being around Kokushibo and Daki, but he’s scared of Douma and Enmu.

Jackyll (The Villain)

This piece was done by @shycroissanti

Jackyll is a ram humanoid demon. Basically, humanoids are anthropomorphic animals that were persecuted by humans because they were believed to be demons. However, only a few of them actually are. Now they live on a secluded island where they have rebuilt their civilization. The doesn’t mean that they’re safe, though.

Humanoids have demons too and Jackyll is the most powerful one. Humanoid demons only eat humanoids, not humans, and they’ve actually have been around before Muzan became a demon. However, they couldn’t become more powerful due to humans discriminating humanoids and due to a very powerful humanoid slayer!

Jackyll has the strength of Kokushibo and he’s incredibly power hungry. He has black fur with blue, purple and green striped horns and hooves. He can create dangerous shockwaves that can knock a person back. He also hits incredibly hard with his hooves and horns. He also has an “X” shaped scar on his snout that Muzan left on him.

He was there at the battle of the jaguar demon. He was hoping to use Strifles as an eternal food source, but Inosuke and Douma fought him off. (Douma almost died though.) Then Tanjiro, the demons, and the Hashiras learned all about the humanoids from Tamayo.

Jackyll isn’t finished yet. He teams up with Gyokko so he could steal Muzan’s blood. They end up finding some in Muzan’s abandoned lab, but Jackyll drinks all of it and devours Gyokko. Jackyll grows six tentacles on his back that have blades at the tips. He is also a lot more powerful than before.

He then proceeds to make his way to the Infinity Castle. All the demons try their best to stop him, but almost all of them nearly die (Gyutaro almost gets ripped in half and Douma’s face was shredded).

He was about to kill Akaza and Kokushibo when Tanjiro rushes in front of them and takes the hit. Tanjiro then fights off the ram. He’s just as fast and powerful, but his duty to protect his own fuels him to take the ram down. Tanjiro ends to defeating Jackyll by cutting off one of his horns.
