[Danganronpa] The Theory of Causality

Another world in an alternate timeline, but Junko's death sent it toward an unexpected ending. The future of the world has already been set in stone. People can't change it. Anyone who tries to force a change will have to pay the price. Serious story, no pairing... I chose the danmei category because I had to; it really doesn't fit any of the other three. Revised.
