After a murder has taken place, the students must work together to investigate and reveal the culprit, dubbed as the "blackened". Like the Killing School Life, the Killing School Trip is a killing game where the students are forced to murder each other in order to escape. However, Izuru's true aim was to set up a battle between hope and despair, allowing him to choose which side to take once and for all. Their plan was to make the Junko AI inhabit their bodies by "killing" them in the simulation, effectively reviving their leader several times over. Izuru then started to upload an AI version of Junko into the program, corrupting it and forcing the Remnants to take part in a killing game.

Ultimately, he remained undecided between hope and despair, and thus merely spent his tenure as a member of Ultimate Despair in order to witness Junko's despair while looking for an opportunity to pit hope and despair against each other.Īfter Junko's death, Izuru convinced the other Remnants of Despair to participate in a new plan: allow the Future Foundation to capture them and put them in the Neo World Program, an advanced computer simulation intended to purge the brainwashing that had driven them to despair. Later on, however, Izuru bore witness to another event which served as evidence of how unpredictable hope can be.


He took an interest in despair for its unpredictability after he was persuaded by Junko to take part in the first killing game. Although Izuru was labeled as a Remnant of Despair, he was never brainwashed into committing despair-inducing acts.
