The night air hangs heavy with rumors of the choujin, superpowered mutants capable of monstrous feats. Most people ignore the whispers, dismissing bizarre occurrences as urban legends, but the truth lurks just beneath the surface, waiting for an opportune moment to rip through the mundane. This world, where the line between human and monster blurs, is about to get a whole lot more complicated for two unsuspecting friends.

Tokio, Azuma's perpetually-overshadowed best friend, always feels like he's just trailing behind. But when a savage choujin attack catches them unawares, Tokio’s desperate will to survive sparks an impossible transformation. Now, with burgeoning, dangerous powers he can barely control, he has to navigate a life where hiding his new identity is just as crucial as dodging truancy notices and trying to make sense of the increasingly strange incidents tearing apart their town. Can a sudden superhuman ability be a blessing or a curse when mere survival means keeping your monstrous secret?
