In the 16th century, the French astrologer Nostradamus predicted that the world would end in July, 1999. According to him, cataclysms would transform the Earthinto a lawless place where evil would prevail. As the deadline approaches, little Kappei and several other children are isolated on a Japanese island to train in the mystical arts of Mukai Sappuken to save the planet. The problem is that Nostradamus has royally screwed up, so in the spring of 2022, their master sends them to live a “normal” life. Poor Kappei finds himself in Tokyo with shorts that are really too short, the attitude of a manga character, and the psychosocial baggage of a fossil. His quest for justice brings him his first friend, who introduces him to his first love. The apocalypse fighter has not been trained for this at all, and every emotion totally destabilizes him. However, he will have to adapt, as some of his less grounded comrades will soon force a confontation.

Geats, Revice, and Ryuki wage a fierce battle royale that transcends beyond the Heisei and Reiwa eras.
