Who composed the music for My Hero Academia?

Every screen version of the story carries the same composer’s name. Yuki Hayashi wrote the music for the television series from its first season in 2016 through the final season in 2025, for all four films, and for the OVAs: a single musical voice across 170 episodes and a decade. His brass-and-strings hero themes are as much the franchise’s signature as Umakoshi’s designs, and the score’s most famous piece, the “You Say Run” motif family, became a meme precisely because the show deployed it at every generation-defining moment.

For Vigilantes (2025–26), Hayashi was joined by Shogo Yamashiro and Yuki Furuhashi, a deliberate variation: the prequel sounds related to the parent series without simply reusing it. The games borrowed the same desk, with One’s Justice scored within the franchise’s musical world.
