Kyoko Hatsakure is a normal highschool girl with, so it seems, multiple personalities. When she's around her brother, she has a motherly side, in which she doesn't want anyone to see. Her best friend, Izanami Takahashi, just happens to be an excessively violent gang member belonging to Japan's greatest gang, and is strangely and ironically good with kids. Izanami is the only one who had seen Kyoko's motherly side. When Kyoko was at school, she was popular and loveable, but her reputation is what she cares about. Izanami, on the other hand, could care less. One day, she sees someone helping her brother, Shiki, off of the ground on the sidewalk. She invited him into her house, unaware he was a classmate. He was the same as her. Katsuya Tasuma was an average loser with glasses and long hair at school. When Kyoko found him helping her brother up, he had multiple peircings, no glasses, and his long hair pulled back, in a boyish way. He also didn't really want anyone to know about him. They instantly became friends, but will it progress to something more?
