Two brothers who never knew the outside world step into it broken. The system that imprisoned them didn't fail, it just stopped working, and now they're running through a country that built walls to keep them contained. The Kuroki brothers chasing them aren't antagonists; they're the ones forced to believe the bars were necessary. This isn't about superpowers. It's about what a society does to people it fears, told through the exhaustion of men who escaped a cage they didn't know how to live outside of. The emotional weight sneaks up on you because the show treats captivity like a scar that doesn't heal just because you're finally free.

Naoto and Naoya Kirihara have been held for fifteen years in a research lab for psychics, hidden from society because of their powers. When the barrier keeping them there breaks down, they wake in a forest and hope the world is finally ready to accept people like them, as the lab's head, Kyoujirou Mikuriya, promised. Instead they find Tokyo in 2041, after a third world war erased two-thirds of humanity. Belief in the supernatural is now treated as a dangerous idea, and any depiction of psychic phenomena is censored. Enforcing that view is an elite government task force that includes Takuya and Yuuya Kuroki, brothers abandoned as children and raised by the unit, who have never doubted that such powers are fiction. After a mission brings them into contact with a woman named Shouko Futami, the Kurokis cross paths with the wandering Kiriharas, and a pursuit between two pairs of brothers begins in this psychological sci-fi mystery.
