Hayama, Fuyuki

Akito's father is a business executive who works long hours and is rarely home. While he initially appears to be a bad father, Mr. Hayama proves to be a good one who was simply unaware of the poor relationship between his children because he was working too hard. After realizing Akito's suffering and becoming ill from overwork, he starts spending more time at home. Whenever Akito gets into various scrapes during the series, Mr. Hayama always believes in his son and supports him, even when no one else does. This might be partly due to the fact that he and Akito's mother were troublemakers in their younger years.
Mr. Hayama is very mellow and soft-spoken, but the few moments he breaks out of his quiet mode are very funny. He takes a great liking to Sana and develops a goofy habit of talking to the TV whenever she appears.
