A young girl, Manami, has a split personality. Her alter ego, Nami, only comes awake when her cousin Toru calls her by her Nami name. And when she's Nami, Manami doesn't recall anything at all. Toru hasn't seen Nami in what seems to be years, but he's now living with her and her parents as his mother is recovering from an illness and requires quiet time. And in the intervening years, Manami's turned into a hot little number.
College is mentioned repeatedly that they're in college, cause college is a school.
But not a school like kids go to, cause it's a college. There's one girl at school , er, college however that really doesn't like Manami. She and two friends corner Manami outside of the college and proceed to pin her against the wall and start undressing her. After he bungles, his utterance of the name Nami frees up the alter ego, which proceeds to kick some serious ass. The resolution proves to be rather interesting amusing, but there's very little to this show overall, even with a running time of 80 minutes.
