Danganronpa was orignally a steam game for 15 British Pounds! I reccommend you play it/watch a gameplay after but if you watch it it'll still make sense!
The first season of Danganronpa is based of the first game, Trigger Happy Havoc, where 15 students get told there going to a school for only the students best in their field, but when they get there, they find out it's not a normal school, it's a killing school, held by a monochrome teddy, Monokuma. The rules to the 'game' are simple.
If you kill someone, don't get caught, and you'll get to leave, you get caught? Well theres consquences to suffer.
If you find out who the killer/blackened is, they suffer the consquences and everyone else survives except the person who got killed.
If you guess wrong... Well, everyone but the murderer dies.
I don't recommend it for users who get disgusted by blood, although its pink, it still is blood.
Its a 14-15
