My Hero Academia Final Season will mark the conclusion of one of the most successful superhero anime series and will follow the adaptation of the manga by Horikoshi in its Final War and Epilogue arcs. Season 7 left the world on the edge of ruin, as heroes and villains were engaged in a final battle. The eighth and final season, titled My Hero Academia: Final Season, will be released starting October 4, 2025, and will be a more faithful adaptation of the final chapters of the manga.
My Hero Academia Final Season Episode 1 is titled Toshinori Yagi: Rising Origin. It means that the premiere is specifically devoted to All Might (real name Toshinori Yagi) and his history. The title focuses attention on the symbolic and narrative significance that All Might has at the end, foreshadowing that the initial episode will return to his origins and restore his legacy as the show enters the final phase.

This announcement is accompanied by a central visual of Armored All Might, which further confirms that the initial episode will probably deal with his last fights against All For One. The name Rising Origin refers to his origin as a hero and his ascent out of his lowly roots.
The My Hero Academia Final Season's first episode is likely to follow the manga content at or around Chapter 398, where the Final War arc starts. All Might, in those early chapters, faces All For One, ultimately gets back on his feet in combat, and becomes central in holding the hero side together.
The title implies that the episode will follow his background in flashback or narrative framing and then follow him into conflict. The structure of the manga leaves space for such framing: readers will repeatedly go back to the life All Might once led, when he passed on One For All, and the strains he had to bear.

The preview of My Hero Academia Final Season uses shots of All Might (in his armor), interspersed with shots of Deku, Shigaraki, and destruction in Hero Society. The trailer hints at the premiere being a blend of the past and the present, with All Might and the current war shown side by side.
My Hero Academia Final Season β Why Episode 1 Opens with All Might
There is significance to starting the season 8 with All Might. All Might has been the main icon of peace since very early in the series. Him being the subject of the My Hero Academia Final Season's first episode is an indicator that the final season is aiming to base the finale on his legacy and sacrifice. Considering the title of the episode, the audience is likely to find more emotional appeal than just spectacle.
Since My Hero Academia Final Season will be based on manga Chapters 399-431 (Final War arc up to Epilogue), the premiere has to strike a balance between presenting the final war and memorializing the history of the symbol that started it all. The title of episode 1 also preludes the means to extend the scenes of All Might's earlier life, which were merely sketched in the manga. Horikoshi has also alluded to adding additional scenes or emotional richness to the anime, particularly since he is now a more engaged party since the manga is over.

The returning members of the staff are the director Naomi Nakayama, chief director Kenji Nagasaki, scriptwriter Yosuke Kuroda, character designers Yoshihiko Umakoshi and Hitomi Odashima, and composer Yuki Hayashi. The consistency of creative staff is a strong indication that the emotion and pace of the series will closely align with the past seasons, particularly in managing the dramatic centrality of All Might.
To conclude, the title of My Hero Academia Final Season's Episode 1 is Toshinori Yagi: Rising Origin, and the title gives a solid indication that the episode will build its story around the origin of All Might and his legacy. It will reinterpret the introduction of the Final War arc in the manga - probably with flashbacks to his childhood - and rebrand the conflict through his perspective. Since the presence of All Might has been central to heroism throughout the series, this thematically resonant introduction of the final season is a given.
