Kentaru Mitsuba (三葉ケンたる) (Mr. Mitsuba) is the father of Kenichi and is a workaholic. He likes smoking, drinking sake, eating, singing using his karaoke machine and playing golf.
Physical Appearance Edit
Kentaru is short and plump, as opposed to his wife, who is of average height and much slimmer than her husband. When at home, he wears a blue dressing gown with a belt, but when at work, he wears a brown coat, a white shirt, a blue tie, brown trousers, brown shoes and a brown and gold belt. He has short hair and thick eyebrows.
He is an alcoholic and sometimes gets absent - minded, but he is always with his family to support them and give them some money. Although he gets angry like everybody else, he isn't as short tempered as his wife.
Mr. Mitsuba appears to be on good terms with his family, and although he seldom has much time, he does try to spend time with them (for instance, when he showed his new Android off to Hattori and the gang). He is in an affectionate relationship with his wife, but they do tend to quabble a bit, once in "Mum takes us for a ride" where they argue about the car breaking down; Kentaru makes his wife cry after snapping at her that he doesn't care about how her friends' husbands' treat them.
Mr. Mitsuba is close to Kenichi, but he can lose his temper with him for getting low marks. In one episode, he, Kenichi and Shinzo had a bit of a tiff over an electronic logic game.
Hattori and Shinzo Edit
Mr. Mitsuba gets on well with Hattori and Shinzo, but he can be strict with them. In one episode Mr Mitsuba loses his confidence because he feels that Hattori is more important than him.
Other Ninjas Edit
Mr. Mitsuba sees Tsubame as a good homemaker and relishes her food. He is, however, like his wife, misled by Kemumaki's pretending to be a goody - goody - two - shoes.
Yumeko Kawai Edit
Mr. Mitsuba isn't seen talking to Yumeko often, though they presumably have a good relationship.
Mr. Mitsuba was voiced by Yuzuru Fujimoto.
