Ami's father, the father of Ami Mizuno, was only seen once in a flashback in the manga, and very little was known about him. Ami once said that he was an artist, but otherwise he remained a mysterious figure; in his manga appearance, he was even wearing a hat and sunglasses, so that his face could not be seen.
Ami's parents had divorced at an unknown point in the past, and the only contact Ami had with her father was a birthday card that she received every year. When enchanted by Fisheye in the manga, Ami hallucinated her father telling her that he left them because he could not bear to be near her any more.
