Killing School Trip

The Killing School Trip is a killing game featured in Danganronpa 2: Goodbye Despair. Like the Killing School Life and the Final Killing Game, this is hosted by Monokuma.

Prelude
Although Izuru Kamukura was labeled as a Remnant of Despair, he was never brainwashed into committing despair-inducing acts. He took an interest in despair for its unpredictability, after he was persuaded by Junko Enoshima via the first killing game. Later on, however, Izuru bore witness to another event that serve as evidence of how unpredictable hope can be. 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.

After the death of Junko, 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. Izuru's stated plan was to corrupt the program with an AI based on Junko that could inhabit the bodies of her Remnants by "killing" them in the simulation, effectively reviving their leader several times over. 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.

Danganronpa 2: Goodbye Despair
The game is from Hajime Hinata's point of view as he starts his first year at Hope's Peak Academy. As he walks into the school building, he is overcome with fatigue. When he recovers, he finds himself in front of a door. He has the strong urge to open it and once he does, he finds himself in a classroom full of his new classmates.

They suddenly find themselves locked in the classroom and a pink bunny, Usami, appears before them, claiming herself the class' teacher. Suddenly the classroom around them falls away to reveal a paradise-like island. Usami tells them that they are on a school trip and they are to befriend each other to gain hope fragments and make their hope grow. Just as they get used to the peaceful island life, Monokuma appears and takes control of the island, announcing that the students must participate in a life of mutual killing if they wish to escape.

List Of Rules

 * Usami's rules:
 * Rule #1: Extreme violence is prohibited on this island. Please live peaceful and relaxing lives with your fellow students.

Results and Aftermath
Ten out of fifteen Remnants of Despair remained comatose in the immediate aftermath, and the other five opted to stay on Jabberwock Island until they could find a way to help them. A peacekeeping squad was dispatched by Kyosuke Munakata to Jabberwock Island to kill the survivors, but Byakuya Togami's own squad saved them and presumably transported all the inhabitants off of the island.

Sometime during the Final Killing Game, all of the comatose victims of the Killing School Trip (except for AI Chiaki who now lives inside Hajime's mind) were awakened from their comas by Izuru. Purged of their previous brainwashing, they joined their remaining friends in rescuing the Future Foundation and stopping Ryota Mitarai from brainwashing the world. After taking the blame for the Final Killing Game, the whole class (including Ryota) decides to return back to Jabberwock Island.

Trivia

 * With 15 non-comatose survivors and an AI that resides within someone's mind, the Killing School Trip is thus far the killing game with the least casualty.
