Each time he gets "slpash" with cold water, he become, a girl,  To become his self again, he needs to be splashed with hot water.... But that is not his only "problem" because his father engaged him to "many" ( Akane and Ukyo) girls to ba able to get FOOD....there are much bla bla bla but i am too lazy to keep telling you about the story.
