Jabberwock Island – once a popular tourist destination, this now uninhabited island remains oddly pristine. You and your classmates at the elite Hope's Peak Academy have been brought to this island by your super-cute teacher for a “lovey-dovey, heart-throbbing school trip.” Everyone seems to be having fun in the sun...until Monokuma returns to restart his murderous game! Trapped on this island of mutual killing, your only hope of escape rests in solving the island’s mysteries. But be warned—sometimes the truth can be its own despair...

Danganronpa 2x2 features the same cast, setting, and premise as Danganronpa 2: Goodbye Despair, but with a brand new full-length scenario that deviates from its predecessor very early on, resulting in a killing game with a fresh chain of victims, culprits, and tricks.
