Third volume in the 2 Channel series.

After a childhood friend's suicide, Hideaki and his former classmates reunite to pay their respects. Soon after, a DVD, marked X arrives revealing a man being tortured, triggering a flashback in Hideaki, reminding him of witnessing a schoolmate being subjected to humiliating batsu (punishment) games. One evening, Hideaki is kidnapped and when he awakens the next day, he discovers he is in a recreation of his old school-room, along with his fellow classmates. Trapped and held captive by mysterious hooded figures, each of them must now play a brutally violent, version of the punishment game, in order to survive.

Masamichi is about to take up postgraduate study. He invites six student friends round for a farewell dinner at his Kyoto flat.

Tragedy begins with curiosity. The on-line killer website broadcasts scenes of death in real time. Viewers are drawn to the website through curiosity, and then are shocked by what they see. Against their will, random viewers are selected to enter the killing game. It is literally a life and death situation to survive in this cruelest of spectator sports.
