Yukawa is constantly bullied by a group of three classmates until one day, he is saved by a stranger named Nishida Shin who knows Kendo. Nishida begins teaching him Kendo, causing him to become more active, outgoing, happy, and cool, and to no longer be bullied. However, one day when they board a bus, a man begins threatening another man for staring at him, going to the extent of cutting the other man's hair and dragging him off to bus. Yukawa's image of his hero is shattered when Nishida fails to intervene, supposedly afraid of putting Yukawa in harm's way. He accesses the Hell Correspondence website, receiving Ren as a doll, and sends Nishida to Hell. Feeling that the world cannot change even if he himself changes, Yukawa quits Kendo and reverts to his former timid self.
