Chuya Nakahara

Vampires in this AU aren't afraid of the sun and don't react to it. They act like normal humans, but their irises turn scarlet, which can only be hidden by contact lenses, and their teeth become sharp for attack.

Nakahara also frequently ventures into the forest and into the city. He wears bright blue contact lenses to make himself look like an ordinary passerby. Few people knew this, as they were unfamiliar with his basic appearance.

The building consists of five floors and a basement. It was once very popular, but for unknown reasons, people abandoned it. The abandoned structure is surrounded by a dense forest that stretches for over a kilometer. This forest is deserted except for owl-like birds.

The ladders to the roof were broken, and vines and other plants were hanging from the walls. The corpses of Nakahara's victims can sometimes be seen on all floors. Unusual sounds can be heard in the building: a distant, quiet rumble on the third floor, loud bangs, heavy footsteps, Nakahara's quiet laughter, and other strange noises.

Saya (girl), Mika (girl), Sato (boy) and Tanako (boy).

Age: 22 years.

Appearance: A young man of average height (180 cm) with a muscular build. He has large eyes with scarlet irises and bright red hair parted on the right side, reaching to his shoulders. His bangs are parted on the right side, visually covering the right side of his face. He wears his hair tied back in a ponytail and combed to the left.

Ability: "Vague Sadness" (manipulation of the gravitational field and the gravity of objects in physical contact with it). The ability's true form, "Corruption," allows one to manipulate gravitons in the surrounding area, increase one's own density (crush a tank with one's bare hands), and fire balls of compressed gravity that act like black holes.

Personality: Quite calm, cunning, and intelligent. He attacks from ambush. He's difficult to bribe or, worse, lure into a trap. Few managed to escape from him, as he was also a vampire, but he VERY rarely attacked anyone, turning them into vampires.
