Wars? It’s already 800 years since the last one. Monsters? The Guild and Order of Knight are taking care of them. Return to Earth? It is eventually No-Risk.

A kind world where the three races, the Spirit World’s Magical Races, the Celestial World’s Divine Races, the Mortal World’s Human Races, they are kind neighbors to each other, with everyone living a peaceful and fulfilling life.

But although I wished to peacefully spend a year before my return, for some reason, the heavyweights of this world keeps gathering around me, and……

Entering Tokyo in the bubble era, in this strange era, the only familiar ones are Matsuda Seiko, Nakamori Akina, Kudo Shizuka…
