Haruyuki Arita is a middle school student and is overweight. He has been bullied for many years and because of that likes to go to places where no one is like the squash game on the local network at school. The incident that further triggered his desire for loneliness was when he was in elementary school. He killed all of his classmates during a game over the global net and was bullied by all of them and pushed further in to hiding.
