One day a little girl with bewildering supernatural powers dropped right into the middle of an ambitious young yakuza members life. His name was Yoshifumi Nitta, and hers was Hina. Thus began their days together (forcibly, thanks to Hinas powers). Now a year has passed, Nitta has taken over the title of lieutenant in his syndicate, and he seems to be doing well enough in his role as Hinas pretend father. Yet the duos time together is rarely peaceful; every day seems to hold a new calamity in store.
