I watched Danganronpa all the way through in one day and I'm absolutely obsessed with it. The plot is absolutely amazing and the way that they portray the characters is phenomenal.
There are absolutely no spoilers in my review. You are free to look as you please.
The layout is basically every other, so for every murder, there's a class trial, except for the first episode. It's basically just character introductions.
There's a huge plot twist at the end that you really wouldn't have thought of at first but when you realize how realistic it is, you'll love it even more.
I seriously enjoy this series and I highly recommend it to anyone who loves mysteries. You seriously aren't able to assume the murderer until Naegi has made an extremely fair point and you go along with his assumption. I hope you enjoy the series and I hope my review helped.
