Yoichi Tanaka Husbando

Yoichi Tanaka is Kou Mabuchi's older brother by eight years. He works as an English teacher at Futaba's high school. Futaba Yoshioka was initially interested in Yoichi upon entering high school because he reminded her of Kou, but was unaware that the two were brothers. Yoichi knows about Shuuko's crush on him but always rebuffs her advances, telling her that he will never see her as anything more than a student. However, he never hesitates to help her in times of need and is happy whenever he sees that she is fitting in. He enjoys a playful 'rivalry' with Aya Kominato over Shuko Murao. He often gives Futaba advice whenever she feels unsure about herself or about Kou. Tanaka, or commonly called Tanaka-sensei, has short black hair and slender eyes (which resemble Kou's). But, unlike Kou, Yoichi has a very inviting face and resembles the first year middle-schooler Kou. Tanaka has two moles on his face, one under his left eye and one on his right eyelid (which he calls his hidden item). In flash backs of Tanaka in college, it's shown he grew his hair out into a short and shaggy mullet. Tanaka is secretly made fun of by students, because of his weird clothes. He is considered handsome. Tanaka is kind, but can be a bit emotional and childish. He's a responsible teacher and loving brother (yet wishes the love he shows for Kou could be reciprocated). The only times Tanaka becomes more serious is when Kou isn't doing well in school, or when Shuuko is trying her "sneaky" things on him. He also acts sort of sarcastic towards Aya.
