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.
Two brothers, Naoto and Naoya Kirihara, have spent their entire lives trapped inside a research facility designed to contain their psychic abilities. When the barrier holding them fails, they finally taste freedom, only to discover the outside world has moved on without them. A shadowy organization immediately mobilizes to recapture them, sending the Kuroki brothers,operatives with their own supernatural gifts,to hunt them down. As the Kiriharas flee across a modern Japan they barely recognize, questions multiply faster than answers. Why were they locked away? What do their captors really want? And what exactly are the limits of their powers? The brothers must navigate a landscape where no one can be trusted while grappling with the psychological scars of their confinement and the realization that their abilities come with consequences neither fully understands. What begins as a chase becomes something far more complex: a collision between people searching for freedom and those desperate to control what they don't comprehend. The line between hunter and hunted blurs as everyone involved discovers they're caught in something much larger than any individual survival.
