Danganronpa style: It's a much more slower paced fight to the death. A murder mystery based game, anime series filled with motives & plot twist . It revolves around a cast of students being trapped inside of a school & the only way out is kill someone and NOT be found guilty in a class trial. The main character's job is to solve the mysteries and find the mastermind. If they fail, everyone dies, but the murderer & vice versa.
Anyway this was the first thing that came to mind. That & some good old fashioned Spartan gladiator coliseum battle Royale action.
S/N: I see Sassy already declined. Lol
That sounds like a pretty cool anime. I’ll have to look it up. Hopefully it’s on Hulu or Netflix. We don’t have crunchy roll.
