Story

Blue skies, white clouds... shimmering seas and sprawling sandy beaches.
The students of Hope's Peak Academy were on a school trip to Jabberwock Island, a famous resort island in the south, but they were trapped there by the headmaster's evil plan.
In order to escape the island, the students are forced to participate in a killing game, then a class trial to find the culprit.
The class trials unfold at a high speed and tempo, with testimonies and evidence collected in the investigation part being used as bullets and set to triggers, knocking out contradictions in the opponent's claims to advance.

Swirling suspicion. Invisible madness. In the midst of this extreme situation, an evolved class trial begins.
