-The 25 students at the training school soon learn they are here because the Milki Masters know of an appending apocalypse – the end of the universe, referring to the apocalypse only as the TFC (Terrible Future Calamity). At the end of the training schools period, one of the groups will be chosen to go on a mission to find out what will cause the TFC, and try to stop it. In order to win, the group must win competitions in different categories to earn points.
