Kokolight - Tumblr Posts
So @snivyartjpeg shared their warmup doodles in the discord server of a kokolight vampire au. And I swear, as soon as I saw it, my brain instantly desired to make something based off of it. How could I not?
Not much to say on this honestly. I just wanted to write something fun based on the cute doodles! So enjoy!
Vampires existed. They lived and breathed in the same world as humans. That was an undeniable fact. Yakou knew this and accepted this.
But what he had not expected was for one of his own employees to be one.
His first clue had been a few bloody tissues left in the trash can. As far as he knew, no one had been having intense nosebleeds aside from possibly Desuhiko. But no clients had come to the agency and no… magazines were here. So the possibility of the disguise detective being the bleeder was minimal.
So at that point, he tried to subtly observe his employees a little more.
He instantly ruled Fubuki out as the one hiding their true status, as she couldn’t lie to save her life. Desuhiko was ruled out too, as he was not very good at convincing. So he surely wouldn’t have been able to talk someone into providing blood. And Yuma? Obviously not, as the small rookie detective couldn’t hurt a fly.
Which left two contenders. Halara and Vivia.
This was where the search got a little more difficult. Those two were incredibly guarded individuals, not letting much slip past their walls. They could keep secrets no problem, and their poker faces were solid.
But after some watching, Yakou thought he nailed it down.
Vivia Twilight.
It seemed obvious once he connected the dots. The man always appeared to be sleeping during the day, as vampires were typically nocturnal creatures. His skin was pale, like he didn’t have great blood circulation as vampires tended to suffer from. His ability to be incredibly stealthy when he needed to. And the constant insistence that he wanted to die someday. Perhaps a mindset he got from needing to drain people’s lifeblood to survive.
And in addition to figuring this out, he also discovered who Vivia must have been feeding off of. Yuma Kokohead.
The two of them had gotten close since they started working together. It was fairly common to see them next to each other, whether it be naps, talks, or eating regular food. So he was certainly easy to access as a food source. Yuma also was fairly agreeable and could be convinced easily. He always wore that navy blue scarf, concealing his neck and potentially hiding the bite marks.
It all fit in Yakou’s mind. Surely he had figured it out.
But he couldn’t put the thought to bed until he had concrete proof. So he devised a little scheme.
It had started with sending Halara, Fubuki and Desuhiko out to do some jobs. He also claimed that he had errands to run, so he gave instructions to the last two. “Stay here in the agency and keep watch over the place. If clients come in, entertain them until I return. Understood?”
Yuma nodded with a beaming smile. “We won’t let you down, Chief!” Vivia hummed his agreement from the fireplace.
“Okay then. I’ll be back in an hour,” he told them. Then he left the submarine.
To his credit, he did go do some errands to kill time. But he returned to the sub after half an hour. He knew that by giving them a time frame, they might try something while they believed themselves to be alone with no interruptions. So it was the best time to try and get his proof.
He carefully unlocked the hatch, descending into the hull and turning around. The lights had been turned off, but the sound of clothes rustling was audible. Vampires preferred darkness over light, so this was a good sign. But he needed more information. So he took some sneaky steps towards the room’s opening, until he was just barely hidden. Then he suddenly rounded the corner.
And what he found there had not been what he expected.
Oh, there was a vampire in his submarine alright, but the glowing red eyes and bloody fangs didn’t belong to who he had thought. Yuma’s eyes shone in the dark as they turned towards him while perched on Vivia’s lap. His tongue darted out to lap up a tiny trickle of blood that was dripping down his chin.
Meanwhile, Vivia had been sitting upright on the sofa, head tilted to the side and his neck exposed with several bite marks now on display with his coat off. The lazy detective opened his eyes upon feeling the vampire stop, then caught sight of the flabbergasted Yakou. “Oh, hey Chief,” he called out, acting as though nothing was wrong.
“Wha-? But… I thought… Yuma’s the vampire?!” he managed to exclaim, running a hand through his frazzled hair.
“Uh… sorry? I wasn’t really sure… how to tell you,” the rookie said with an embarrassed tone. “But it’s okay! Vivia helps me with my blood urges, so there’s nothing to fear!”
Yakou rubbed his temples, trying to not get overly upset that his theory had been the complete opposite. “It’s fine, it’s fine. If you got it under control, then I see no reason to worry.” He sighed, then reached for the light switch. “Turning on the lights now. Close your eyes.”
He waited until the red glow vanished from the room, then flipped the switch. He grabbed the grocery bag that he had left near the hatch and entered the room again, ready to discuss things with his employees.
But when he returned, Yuma had somehow vanished from sight. Only Vivia was in the room, busy with tying a dark bandage around his collection of bite marks. “Uh… where’s Yuma?” he asked, very confused on where the rookie had disappeared to.
Vivia smiled. “He gets sleepy after a meal. And… he insists on resting with me.”
Yakou was about to insist on a better explanation when he noticed a new shade of lilac on the taller detective’s hair. Walking closer revealed something quite endearing.
A small purple vampire bat with Yuma’s signature hair antenna was nestled into the green hair. He let out a yawn, then snapped his jaws closed and snuggled deeper into the locks. That, Yakou would admit, was adorable.
“I see. Well, I’ll leave you two to rest, I guess. I’ll try to be quiet,” he told them, then finishing the journey to the kitchen to put the groceries away. He did try to keep his promise, and worked as silently as possible.
Once everything was put away, he peeked into the lobby again. Vivia had retreated to the fireplace, the tiny bat still in his hair. Both looked dead to the world.
That was good, he supposed. Better to let them get some relaxation time while they could before the next big job. And the sight was enough to heal his wounded pride as a detective.
He turned his eyes away from the pair, settling down in his chair and opening the newspaper. Time to get back to business.

A little drabble scenario idea I put together for @snivyartjpeg’s Kokolight Vampire AU 💜💚🦇
To Care for a Sick Vampire
Yuma seems to be even more tired/weak than usual one day and Vivia notices that something is wrong with him. He asks him if he wants to feed on any of his blood to possibly re-energize him. But to Vivia’s surprise, Yuma refuses the offer outright.
“You look tired, Yuma… Are you…hungry? Do you need to feed? I will provide for you anytime you ask…”
“…No.”
This concerns Vivia but then he notices how pale and sickly Yuma looks, even more than usual. He puts his hand to Yuma’s cheek, but it wasn’t warm. Of course not, he’s a vampire. They probably don’t get fevers to begin with since vampire blood runs cold. But he definitely wasn’t well, that much was certain.
Vivia decides to slice the palm of his hand with his large boxknife he keeps in his pocket and places it in front of Yuma’s face.
“You…need to eat, Yuma… Even if it’s just a little bit…otherwise…you won’t feel any better…”
Yuma looks hesitant at first but then complies as the scent of Vivia’s blood does tempt his urges despite his weak state. He leans his head down slowly and weakly licks and laps the fresh cut on Vivia’s palm. He does it very slowly, but he has a small expression of relief. Even if he wasn’t well, he did still want to eat. But he didn’t want to consume large amounts of blood in this state, in his fear of possibly losing himself due to the weakness and sickly feeling that he felt.
He didn’t want to cause any further trouble for the agency, especially the Chief now that his secret was out to him. He also didn’t want to unexpectedly hurt anyone if his blood urges had gone out of control. It wasn’t safe for him to be blood drunk right now.
At least, that was his worry since he didn’t really understand how his vampiric urges worked due to his amnesia. But he didn’t want to take any chances if his current state wasn’t in good condition. He couldn’t risk causing any more trouble for everyone.
Even if that meant… starving himself.
Thankfully, this small amount of blood that Vivia provided for him seemed to suffice well enough. He stops lapping the cut, looking up to his tall human partner above him.
“…Thank you…Vivia…”
After a very small feeding, he transforms into his little lilac bat form and he tries to fly. But he was still too weak as he falls downward face down toward the floor. But Vivia catches him in his hands just in time.
“You’re too weak, Yuma… I will offer more to you…after you rest for a bit…”
Yuma spends the rest of the day resting/sleeping on Vivia’s hair/lap/shoulder/arms. The poor thing was trembling the whole time. And Vivia continued to feed Yuma very small amounts of his blood whenever he looked too weak, to which the tiny sickly bat would slowly lap up like a delicate little newborn kitten. Over time, Vivia ends up with multiple cuts on his left arm.
Later, Yakou enters the sub safely after seeing that the two were not doing anything TOO weird while they were alone. Seeing Yuma in bat form probably meant they were done. But then he looks to Vivia in shock noticing his left arm is covered in bloody self inflicted wounds.
“Vivia!? What happened to your arm?! Okay, what kind of crazy blood ritual did you two do this time?!”
Vivia gently places his right uninjured hand to where Yuma lay, and a soft weak sounding squeak came from the tiny little bat as he was touched. Yakou also settled his freakout down as he heard the weak bat’s cry.
“Yuma is…not feeling well so…I’m giving him only small amounts of my blood for now… But the blood of the cuts…don’t stay fresh forever…”
“Oh, I see… well that’s not good. Is there anything I can do to help?”
“Just…leave Yuma to me, Chief…”
Yakou didn’t argue. After all, he had no idea how to care for a sick vampire.
“Okay, but don’t you dare die from blood loss, you hear me?!”
Vivia smiled without saying a word further.
It looked like it was now Vivia’s turn to look after and take care of his weak little vampire partner for the day. Time to repay the favor for all the times he looked after him.
