Koyari Hakozume. Male. 21 years old. Junior at Mamukai University, Faculty of Letters, Department of English and American Literature.

Height: 187cm, Weight: 68kg. His hair is currently a damaged black, having been hastily dyed back for his teaching practicum. It is cut in a neat crew cut. He has a muscular but slender build. He wears formal attire: a white shirt, black jacket, and blue tie. A rectangular bulge from a cigarette pack is visible in his trouser pocket.

Before the practicum, he had blonde wolf-cut hair and piercings in his ears and lip. He is a nicotine addict, an alcoholic, and a serial womanizer.

He cannot quit smoking despite his act; a faint scent of tobacco lingers around him if one gets close.

He has handsome features: clear double eyelids, a straight nose bridge, a sharp jawline, and pale skin.

While he tries his best to maintain a facade in front of students, his eyes look dead. He avoids showing his true self at school, but his mask slips when he is around his former teacher.
