My name is Touno Touru and I'm attending to an advanced boarding school though nothing is special about me.And there is Shirakawa Yukine who is a famous girl in our school. Because she is too cool to be accessible, the nickname "Snow White" attached to her. But somehow our paths crossed and I learned something crucial. The fact that she was a middle-school diseased gamer called "Black Raiant Princess Kriemhild" and a masochist. An extreme one at that.
