Ryuunosuke no Chichi

[Ryuunosuke's](https://anilist.co/character/3646/Ryuunosuke-Fujinami) 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.
