The 21st volume of the My Hero Academia manga by Kōhei Horikoshi ranked #3 on The New York Times' Graphic Books and Manga bestseller list. Viz Media shipped the book on October 1, and it describes the volume:

Endeavor and Dabi's battle rages across the city as Endeavor fights to solidify his new position as the number one hero. Hawks provides support, but where do his loyalties really lie? Midoriya experiences a cryptic dream about the past—what secrets do the previous wielders of One For All have to show him? Then Class 1-A's joint battle training with Class B begins.

The New York Times posted its first Graphic Books and Manga bestseller list in October, and it is one category of the newspaper's new bestseller lists.
