Concrete Revolutio: Choujin Gensou - The Last Song

Titans from outer space, creatures from a mythical realm, ghosts and goblins from the past, cyborgs made by scientists, and artifacts that sprang from the ruins of old civilizations are some of the creatures that can be seen. It's not simply a hypothetical situation in another Japan; it actually exists. While some enjoy their superhuman fame, some of the superhumans decide to keep their identities a secret. A member of the Superhuman Bureau named Jiro Hitoyoshi keeps tabs on their activities.
