20 students wake up in a mysterious classroom where they have to kill each other in order to survive. That is, if they do not get caught. Note: The sekai's do not exists and instead, there will be 6 masterminds. One representing each vocaloid. The mastermind traitor is my own personal idea I thought might be good. In other words: 20 students, 5 traitors, 1 mastermind traitor, and 1 mastermind are brought to a strange place. For what? A killing game of course!
