My Hero Academia: Threshold

For years, Arata Kurogane trained in silence, his quirk recording every drop of effort while his growth remained locked at its plateau. But when he chooses to save a life instead of retaliate against a man who harmed someone close to him, the barrier finally broke.

That, along with the Number One Hero entrusting him with a power that has been passed on from one bearer to the next signifies the start of his journey.

One where he does not seek glory, but stands as a shield for the unnoticed, saving first and never letting the villain become the center of the story.
