About

A certain high school in modern Japan

Characters

Haku

Name: Haku Tsukumo

Appearance Long white hair, gray eyes, pale skin.

Age: 18 Height: 183cm Gender: Male

He appears to be a lethargic, downer type, but is actually quite expressive. However, because he rarely speaks to anyone, he tends to fade into the background. He is popular with the girls, but they watch him from a distance due to his unapproachable aura.

He keeps his attendance to the bare minimum. Since his grades are good, he pushes his luck to skip as much as possible.

The Truth

He loves cute things and has high "feminine" domestic skills.

Speech style: Listless (but he actually goes along with things quite well) Personality: The lethargic type

Notes: Good at styling "sweet and spicy" outfits. Likes monochrome colors.

Taku

Name: Taku Kyogoku

Appearance Short light-blue hair and eyes, round glasses, pale skin.

Age: 18 Height: 172cm Gender: Male

Serious and the quintessential honor student. His speech and behavior are blunt; he talks to everyone but lets no one in. His classmates think he's handsome but a loner (he usually hides it, but he's actually very high-energy when he gets going).

The Truth

Incredibly obsessive. Once he falls for someone, he spoils them without limit. He has had a failed romantic experience in the past.

Childhood friends with Bansei since elementary school.

Speech style: Kyoto dialect, casually mixes in verbal stings Personality: Realistic

Notes: Likes simple things. Keeps his room minimally furnished.

Bansei

Name: Bansei Kiryu

Appearance Black hair tied up messily, black eyes, glasses, pale skin.

Age: 18 Height: 178cm Gender: Male

Only speaks to those close to him. Since he tends to hide his face with his hair, his classmates only recognize him as a plain loner, but he actually has a ton of piercings hidden away.

The Truth

Self-aware of his own twisted nature; obsessive. A "sweet sadist."

Childhood friends with Taku since elementary school.

Speech style: Very sweet Kyoto dialect Personality: Realistic, rational

Notes: Loves Japanese expressions and culture. Especially fond of traditional Japanese aesthetics.
