Tasuketsu

Aside from his dislike of PCs, Saneatsu is a completely normal student; however, when he receives a strange message during computer science class, his life is turned upside down; a deadly game begins for him and his classmates.

The survivors move forward looking for post boxes, rights, and hope; those who have rights begin to make their move.

After people suddenly disappear on Earth, the last remnants are invited by the mysterious Emperor to play a deadly game wherein the majority die.

After the confrontation with Shinozaki, Omi and Kazuhiko are separated from the rest of the group; while fleeing from their pursuer, they encounter a boy who has the means to reunite the students.

Iruga demands that Saneatsu and his friends hand over Midō and Omi to him so that he can overthrow the Emperor; in return, he reveals the goal that he and his partner are pursuing; in Nerima, Sudō encounters his teacher, Shinozaki and Midō.

Threads of possibility start to come together, and so do the people associated with them; as Saneatsu tries to unravel a new mystery within Taskuetsu, alliances are formed and a team assembles.
