Mr. Ayano (a.k.a. Ayano) is the father of Aya Ayano and the husband of Mrs. Ayano.

Mr. Ayano only appears in one episode, and his face isn't shown, but it can be seen that he has short, dirty blonde hair (like Aya's) and stubble (Like Katsumi Matsunaga).

He wears a dark green t-shirt and has a Black watch on his left wrist, but his other clothes are not shown.

Mr. Ayano is first mentioned in "Body Paint" when Aya mentions that her family decided to escape Yomiyama City, because it was the only way to protect themselves. By the time Aya got home, her parents had packed their car for an extended trip, and several cartons were in the front hallways for movers.

Driving along a mountain road, the Ayano's had almost escaped when several loose rocks fell off the mountain, one landing right on the car's windshield. Mr. Ayano, who was driving, lost control and drove through the guardrail off the side of a precipice. The student gossip at the beginning of "Glass Eye" states there were no survivors, suggesting that he and his family were either killed instantly or died in the hospital despite the efforts of the doctors.
