The Ultimate Weapon Returns After 100 Million Years

The Ultimate Weapon Returns After 100 Million Years is a post-apocalyptic action fantasy that follows Jin Shidō, humanity’s strongest agent who was transformed into the ultimate weapon through brutal experimentation. Despite gaining overwhelming power, he fails to save the world in time, as humanity is nearly wiped out by monstrous beings known as “Corrupters,” creatures born from human pollution.

With no way to reverse the destruction, Jin chooses to place his hope in the future by entering a deep sleep.
