Makes an appearance - Utau Ehon 1 2 3 Hai!!
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.
