Kusan is Tetsu's "older sister". She is in reality a spirit that resides in corporal form and resides with the Sakura family as she is the spirit that rules that plot of land. She is some-what vain as she steals Tetsu's savings for clothes, and once trades the deed to their house for a credit card that never runs out of money. Kusan as business-wise as she is really cares for her family.
