Summer gave us not one, but two series of Danganronpa animes. There was the Future arc (characters above) that focused on the end portion of the overall story line and the Despair arc that focused on how it all began and was more of a prequel to the second Danganronpa game.
Danganronpa started out as a PSP game where you were trapped in a high school and the only way out is to kill another student and not be caught in the class trial. This was eventually localised and released on the Vita in the west. Since then, it has also been ported to Steam. The original anime covered the first games story but didn’t really do it justice. Not really a surprise when you try and cram a 20 hour game into a 6 hour anime. Luckily, the Danganronpa 3 anime covers new material.
The Future arc covers another killing game with the cast trying to identify a traitor amongst them while also trying to figure out and end to the wave of Despair. The Despair arc is centered around the cast of the second game and shows how they got to be friends while Hope’s Peak school slowly turns into chaos and despair. It’s an interesting approach to try and wrap up all the events of the games, even the characters from Ultra Despair Girls appear but it does falter slightly with the ending.
Danganronpa is all about the story so I’ve not really mentioned it much here. If you have played the games then its well worth watching to see where it goes. If you haven’t played the games then chances are you will be rather lost. Just be ready to hear the word zetsubou over and over again.
