Author's Notes

Volume 20! Thanks for picking it up! my little sister's friend's son is a fan of Jiro, and I hear he was influenced enough to start talking guitar lessons! Jiro is one rocking girl who can play both guitar and bass! Rock, on Kyoka Jiro!!

Volume Summary

With All Might in retirement, Endeavor takes up the mantle of the number one hero, a position he’s coveted for years. But now that he has it, he’s not entirely comfortable with the responsibilities and risks that come with it—both heroes and villains are always gunning for number one. What does the future hold for Izuku, and what do his dreams about One For All mean?

  • The cover of Volume 20 appears to be a reference to the poster for Star Wars: Episode IV – A New Hope, due to it containing very similar framing of its characters.
  • The cover is also a similar homage to the cover of Naruto Volume 37: Shikamaru's Battle!! with Izuku standing in the position holding his hands in the air with a tiger-like hand seal similar to Naruto's.
