Super Danganronpa 2: Nanami Chiaki no Sayonara Zetsubou Daibouken

Chiaki Nanami is the Ultimate Gamer, selected as one of Japan's most expert teens to attend the elite Hope's Peak High School. What could be nicer than for the semester to kick off with a class trip to the tropical resort of Jabberwock Island? And what could be more horrific than being 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! With no margin for error and high stakes, the Ultimate Gamer will need to use all her playing skills to suss out the secrets of Jabberwock Island and find the "true ending" for Nanami and her friends…survival and escape!
