Hiroshi Izumi, is Ken and Caron's father and also a doctor. He does seem to have a lot of scientific knowledge. He usually wears a blue suit and has a moustache. On his days off, he sometimes wears a vest.
He cares a lot for his family and is usually stern and serious. He will always do what he can to back up Ken on his missions and protect his wife and children. He works as a doctor but we never get to see him work.
