Titans from outer space, life forms from a mystical world, phantoms and goblins from ancient times, cyborgs created by scientists, relics that rose out of the ruins of ancient civilizations. In another Japan, it's not just a question of "what if"—it's a reality. Some of the superhumans choose to keep their identities a secret, while others bask in their superhuman fame.
