Хаяма Акіто

Akito is characterized as a lone-wolf because he is quiet, reserved, and likes to keep himself at a distance from everyone. He carries with him a burden of blame from his family for the death of his mother, which he did not cause. But because of his troubled past and problems at school, Akito is maliciously referred to as a devil by his family. As the ring leader of a vicious group of hooligans, Akito and his thugs spend their days bullying the school. But things started to change when Sana came along, he became more nicer and stopped his bullying with the girls in his class.

Akito has a hard time expressing his feelings, especially to someone he cares about, and often shows anger with any personal problem. Most of his behavior can be traced to his troubled family life.

Akito always gets jealous when he sees Sana with another boy. As he puts it, "he doesn't hate her." Later in the series, he becomes angry with the so-called oblivious Sana, who is unaware of his love for her, even though he had kissed her three times (and touched her chest.) He starts dating Fuuka who has confessed to him. Sana becomes jealous and heartbroken, he then tells her that he has always loved her, even though he didn't say anything.

In a later manga named deep clear Akito is married to Sana and the two have a child together.
