Kappei is a martial artist living in a secluded and isolated small island, among many young men training vigorously with their Master to survive the July 1999 apocalypse predicted by Nostradamus — which never came. The Master finally gave up in 2011, disbanded the martial art camp, and sent members back to modern-day Japan. With no knowledge of the modern world, Kappei arrives in Tokyo and starts a new life: as a hero without antagonists.
