Ryuunosuke no Chichi

Ryuunosuke's father, is just about the most obnoxious and loud father there has ever been. His personality can be described as unpredictable and intense. He thinks that it's a man's world and so in his mind, a girl wouldn't be strong enough to be the fourth Fujinami to run the teashop. So his relationship with Ryunosuke is more similar to that of a boxing coach and his prize fighter, rather than a father and daughter.
