I just recently marathon through Dangan Ronpa, I can't believe I missed this amazing series when it was ongoing during the summer. Although it probably would've been better to marathon instead on agonizing it all the twists every episode.
A group of 15 elite high school students are gathered at a very special, high class high school. To graduate from this high school essentially means you'll succeed in life, but graduating is very difficult. The school is presided over by a bear called Monokuma, and he explains to them that their graduation hinges around committing a murder. The only way to graduate is to kill one of your classmates and get away with it. If the other classmates discover the identity of the killer, the killer is the only one executed. However, if they fail to catch the killer, only the killer graduates and the others are annihilated. Which of the 15 will survive the bloodbath to come?
The only downside is that the anime took a 25 hours game and adapt it to a 13 episode anime (Roughly 5 hours), so apparently is seemed rushed. I have never seen the game to say, and it looks quite well done in my opinion. Although I would've wondered how it would have gone if they made it a two-core series. Each episode was well done, having the right amount of stuff in each episode, leaving many suspense along the way.
All in all, this is a very amazing series. One of the better ones I've seen in awhile.
