This is the Book Cover of Danganronpa: Mind of the Raven that the story takes place before the events of Danganronpa V3: Un-bear-able Harmony.

After the events at Jabberwock Island and the defeat of Junko Enoshima in her A.I. Form, Y/n found himself in a completely different place and in another killing game with a different Monokuma unit.

A bi-colored bird one at that.

His name is Monocrow and he forces Y/n and 16 other students to play his own killing game with a new Mastermind watching their every move.

It's up to Y/n, Sora and Yuki to figure out a way to escape from Monocrow and the Mastermind before they and the other all die at the talons of the psychotic bird.

However, Monocrow seems to have the same kind of interest on Y/n the way that Monokuma has when he participates in his games as he and the true mastermind pulling the strings has some plans for the Ultimate Student once he makes it to the Final Trial.

Hope that Monokuma finds out that Y/n has been kidnapped by his avian doppelganger and saves him and possibly the other students from Monocrow's Talons of Despair.
