Haruka, a high‑schooler who has always been content alone, suddenly finds himself and his classmates whisked away to a strange realm where they receive skill points that can be spent on a wide range of abilities and magical talents. By the time he arrives, Haruka is last in line; his points can only be allocated to odd options that the others have dismissed as useless. Though he must once again forge a new life on his own, he actually welcomes the solitude.
His quiet isolation ends quickly when he encounters several of his former peers. Unable to resist their desperate requests, Haruka shelters them and aids in reuniting the group. Yet the various factions clash, each refusing to cooperate, forcing Haruka to devise a strategy that ends their quarrels and reestablishes peace so they can survive this unfamiliar world.
