Mumen Rider in MHA

In a world ruled by Quirks and strength, Satoru Kojima has none.



Bullied. Mocked. Rejected by hero schools. Born without quirk, Satoru should’ve been forgotten. But when his sister is nearly killed in a villain attack, something awakens—not strength, not rage, but resolve.



With nothing but a bicycle, a pair of old goggles, and the quiet conviction that someone has to stand up… Satoru becomes a different kind of hero.



As the city laughs, then watches, then begins to believe, he pedals forward—rescuing strangers, shielding civilians, getting back up after every blow. Injured and exhausted, yet still moving. Still protecting.



And among those watching is Kana—a bratty, powerful girl who sees nothing but weakness in him... until the day she sees him stand against a monster no one else dared face.



This is the story of a boy with no powers who refused to fall.

The story of the lives he touched.

And the legacy he left behind.



“Even without a quirk… I will protect them.”
