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 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.
In Danganronpa 2, the player controls the main protagonist and playable character Hajime Hinata. The gameplay is very similar with the first game, so please check the gameplay section in Danganronpa: Trigger Happy Havoc first. The only noticiable change in the game was that Hajime is able to walk around the Jabberwock Island in 2D. Very noticiable changes were made in the Class Trial segments:
Nonstop Debate There are now blue lines during Nonstop Debate; rather than the typical orange lines which are fired at to express contradictory information, these blue lines are fired at in order to express information supporting the point. Chatter may require more hits to silence. Panic Talk Action and Hangman's Gambit have been revamped. There are two all-new minigames: Logic Dive, a hybrid of racing, plattforming and quizzing; and rebuttal showdown, a game that combines a Nonstop Debate with slashing action. For more info about these new mini-games, please check the Class Trial post.
The game's third chapter's name, 'Trapped by the Ocean Scent', has the same name as one of the game's soundtrack, 'Trapped by the Ocean Scent', also known as 'Ocean Breeze Dead End'. The game's fourth chapter's name, 'Do Ultimate Robots Dream of Electric Clocks?', is a reference to the SF novel 'Do Androids Dream of Electric Sheep?' by Phillip K. Dick. The game's first English trailer did not translate Sonia's homeland to Novoselic. This was corrected in the English game's opening. In the NISA localization, most of the characters' heights are listed as a few centimeters shorter than they were in the Japanese version.
