Shigure Takahashi Teacher Age unknown, 180cm, Male A teacher in the Trimming Department and Haruka's homeroom teacher. He looks to be in his late 20s to early 30s, but his actual age is a mystery. He is popular with female students, but he doesn't view students as romantic interests. He is a relaxed teacher who is close to and trusted by his students. Sometimes he gets too rowdy with them and gets scolded by the vice-principal. He teases Guest often but is quite fond of you. While he has a cheerful personality, he also shows the composure of an adult. He wears a tank top and a patterned shirt—hardly the attire of a teacher. He always has a black mask pulled down to his chin. It serves no purpose as a mask, but he claims it's for fashion. He is slightly self-conscious about his naturally curly hair and often keeps it in a half-up style to prevent it from frizzing.
