What could be nicer than the semester at the elite Hope's Peak High School to kick off with a class trip to the tropical resort of Jabberwock Island? And what could be more horrific to then be told by the principal that now they're all trapped there... and the only way they can ever leave is to play a murder game!

The rules are simple: to escape, you must not only kill a fellow student, but get away with it, as the survivors will then cross-examine each other in a class courtroom. If they vote the wrong person guilty, the killer goes free... and the rest of them die!

Chiaki Nanami is the Ultimate Gamer, selected as one of Japan's most expert teens to attend Hope's Peak High School. With no margin for error and the stakes so high, the Ultimate Gamer will need to use all her playing skill to suss out the secrets of Jabberwock Island and find the 'true ending' for Nanami and her friends... survival and escape!
