Its been a while since the quartet of four worlds were first sent to this strange new school world. While their supposed 'normal school life' has been anything but, they now find themselves in yet another chaotic situation, one which may end in new classmates or the destruction of all of their worlds.

A world where different people who reincarnated from different worlds where gathered to do one thing which was to go to school there, everyone went as smoothly as planned to the one that have sent them there, but one day its plans began to fall a part little by little when an Evil God sends two powerful beings in its world.
