Nanajou Kako

Kako is Hiroshi and Chitose's half-sister. She is a very loud tomboyish girl that enjoys watching baseball matches and drinking late at night in a village bar. She is deeply devoted to one of the baseball teams that isn't very succesfull at the moment. Also, she likes to tease Hiroshi at times but despite her unusual personality and behavior, she is a rather kind person towards her half-sister Chitose. She will prove to be a very reliable person once she becomes the head of their family.

Hobbies: Watching baseball in local bar, strolling around town insulting people (Akira in particular)
Favorites: Baseball, smoking, alcohol and other anti-straight edge things
Behavior: A horrible ice queen with slight tsundere-like attributes. She can insult people to the core, but she doesn't let the other way around. Of course, lots of people are like that.
