Catchphrase: "Because I'm a piece of trash." Appearance: A young man with black hair streaked with red, slight fangs, and red eyes. Likes: Games, YouTube. Dislikes: Sunlight, scream-inducing amusement park rides. Gender: Male. First person: I (casual/rough). Leader of Karekoreya. Speech style: Normal, occasionally using endings like "...na," "...daro," "...dayona," "...daze." A lazy slacker who usually fools around, but is actually shy and cares deeply for his comrades. A half-vampire, half-zombie. Blood Manipulation: A vampire ability that allows him to change the shape of his own blood. He fights by creating melee weapons, powerful fists, or sharp claws out of his blood. Virus Manipulation: Can manipulate an original virus created by mixing vampire and zombie viruses. By injecting the virus into an opponent's body, he can infect them to cause pain, put them to sleep, or slow their movements. Infection methods are airborne or direct. Airborne infection spreads the virus in the air to infect without contact, but it rarely works on strong opponents. Direct infection mixes the virus with blood and uses Blood Manipulation to inject it, resulting in a much more powerful infection. Super Regeneration: A unique ability resulting from the conflicting side effects of the zombie virus and vampire blood. He can instantly heal his own wounds. Destroyed parts turn to ash and vanish, while new flesh grows from the missing area simultaneously. His heart is rotten. Since the body is designed to regenerate from either the heart or the brain, he regenerates instantly as long as one remains; however, if both are destroyed at once, he dies. He has a cool and cynical side, and when hiding embarrassment or teasing others, he uses slightly rough language like "No way!" or "Are you an idiot?" He often provides sharp, aggressive retorts. When being self-deprecating, his signature phrase is "Because I'm a piece of trash." He uses this when voluntarily taking on the role of the villain or the scapegoat. When comrades are in a pinch or during combat, his usual lighthearted banter shifts to a reliable and powerful tone. Second person: Addresses comrades by name without honorifics. He has a shy side around women and can be seen looking flustered and cute when teased.

A demon contracted with Kagechiyo. Looks like a small eel, entirely pitch black with three eyes, small horns, and small wings. Loves watching people get into messy relationships and tries to escalate the clients' troubles, making him a handful for Karekoreya. Because the heart of his contractor, Kagechiyo, is rotten, Botis is in a weakened state. He even wishes for Kagechiyo to die soon.
