The staff of Mushoku Tensei: Jobless Reincarnation III — the third season of one of the most acclaimed isekai anime of the decade — unveiled its third promotional video on Thursday, revealing the ending theme song and confirming new cast members ahead of its July 5 premiere.

Community Reception

The PV has accumulated over 395,000 views on TOHO animation's YouTube channel with an extraordinary 21,760 likes — a stellar like-to-view ratio that signals overwhelming fan excitement. Comments overwhelmingly praise Studio Bind's continued production quality, with one fan noting: "Can't praise Studio Bind enough, you can tell the production quality has improved much more compared to season 2."

Fans are particularly excited about the adaptation of the Eris Training Arc, which is considered one of the strongest narrative arcs in the light novel series. The series has 191,000+ members tracking it on MyAnimeList, placing it among the most anticipated anime of Summer 2026.

Background

Rifujin na Magonote originally serialized Mushoku Tensei on the Shōsetsuka ni Narō website from 2012 to 2015. Kadokawa's MF Books imprint began publishing a print version in 2014, with the 26th volume shipping in November 2022. Seven Seas Entertainment licenses both the original light novel series and the manga adaptation in English. A free-to-play game, Mushoku Tensei: Chronicle of Echoes, is also slated to launch later this year.

What This Means

With Season 3 covering the fan-favorite Eris Training Arc and featuring high-profile musical talent (Mika Nakashima's first anime tie-in in years, plus Yuiko Ōhara returning for the OP), Mushoku Tensei continues to be Studio Bind's flagship production and one of the premier isekai adaptations of the era. The July 5 premiere positions it as a centerpiece of the Summer 2026 season.
