popular guy in school, who Ai has a crush on. The vulgar, bad guy type. According to him, he lost his virginity at age 12. He dated many girls just for the sake of engaging in sexual intercourse or just because he felt like it. This changes when he starts going out with Ai. He has a pretty harsh life at home. His father, a congressman, is actually not his real father. His mother feels guilty about this and tends to take out her anger on him. Nevertheless he still acts carefree all the time. He has been friends with Yuichiro ever since kindergarten and since then they have been in the same class. Ichinose's best friend, he seems to have a thing for Ai but hasn't acted on it. Mina's crazy for him but he seems scared of her after the little incident in junior high. He's been friends with Sô for a long time. He is the exact opposite of Sô, he tends to be more like a gentleman and is not a playboy like his friend. The reason he's such a gentleman to girls is because of his mother. She is pretty and though she may look harmless she actually has a deadly side. One time, in the manga when they were having a parent-teacher conference, Mina's mom had teased him about looking adorable. Of course he had snapped and dissed her. His mom quickly changed from sweet and kind to cold and harsh and warned him about disrespecting women. He falls for Ai and later actually tries to steal her away but he decides to back off a little seeing how much she loves Sô. Mina is a trendy "ko-gal". She thought Ai was after Yuichiro, the guy she liked, so she turned the whole girl population against Ai. But later after she finds out Ai likes Ichinose and not Kato they become best friends. The reason why Yuichiro is afraid of her is actually because of an incident that happened when they were left in a classroom together in junior high. Yuichiro had tried to shy away from her though she never stops chasing after him. She is aware of his feelings for Ai. She hates that he does but there's one event in the manga where she tells him to just to tell Ai that he loves her. Mina is usually vulgar like Sô
