Basketball Guy

Basketball Guy is an unnamed student of Sanada North High.

Appearance
He is tall and of average build, with brown eyes and black hair worn rather messily (in a style not unlike Hidenori's). He is seen wearing a white T-shirt and sports shorts, and carrying a basketball.

Personality
Not much is shown about his personality. Hidenori seems to respect his judgement, and Basketball Guy is willing to help him out.

High School Boys and the Train to School
Hidenori notices a girl who takes the same train every morning that he does. This is because there's a noticeable hair sticking out from the mole on her neck, which he finds repulsive and wants to point out to her. Afraid of the consequences, he stays silent for days, but his discomfort becomes intolerable and he approaches Basketball Guy after school for advice.

He explains the story, and Basketball Guy tells him it's best to remain silent. Hidenori agrees that he shouldn't say anything about a girl's body to her, and is about to continue, but Basketball Guy interrupts him. He tells Hidenori that even if he does tell her, she won't understand that he's being kind. He then walks off, leaving Hidenori to think about the situation.

Trivia

 * He bears some resemblance to a friend of Motoharu and Karasawa, who appears in the manga in Chapter 6. However, the similarity is missing in the anime, since that character's design is changed.
