Hanna just wants to have normal parents. Unfortunately, she doesn't. In fact, they hardly acknowledge her at all. But when she has a fated meeting with a white cat who claims it can grant her any wish, will she be happier? Kuro doesn't like sports. He likes to use his mind. All he wants to do sometimes is plop down on a couch and do a puzzle. But one night, he walks outside to see a black cat waiting for him. It says it needs Kuro's help. It says it will come back in a year and ask him again. Will he lead a normal life? Or will he leave his friends and family to help a cat who claims it needs help?
