Oshi no Ko Season 4: Final Season Status & Release Updates

Oshi no Ko Season 4 is officially in production and has been announced as the anime's Final Season. As of September 11, 2026, the production has not announced a premiere date or release window. Crunchyroll has confirmed it will stream the final season when it debuts.

Oshi no Ko Season 4 is the Final Season

The fourth season was announced after Season 3 concluded and is explicitly labeled the Final Season. That wording matters because it removes the biggest uncertainty surrounding the anime's long-term structure: the television adaptation is now heading toward its conclusion rather than leaving the ending for an unannounced fifth season.

The official announcement confirms production, while Crunchyroll has separately confirmed streaming. Neither source provides a dated premiere. Any claim that Season 4 is a winter, spring, summer or fall 2027 title should therefore be treated as prediction until the production committee publishes a broadcast window.

Where the story stands after Season 3

Season 3 pushed Ruby, Aqua and the people around them much deeper into the entertainment industry's personal and professional conflicts. The final season now has to do more than resolve individual career arcs. It also has to bring the central mystery, Aqua's choices, Ruby's trajectory and the consequences surrounding Ai's legacy into the same endgame.

Because the original manga is complete, the anime team has a known ending to work toward. That is useful for planning, but it does not automatically tell us the episode count. A final season can adapt a large amount of material through a longer cour, split format, extended episodes or another structure. None of those formats has been confirmed.

What the final season needs to cover

The biggest remaining threads involve the truth Aqua has been pursuing, Ruby's increasingly complicated relationship with fame and family, and the way Ai's death continues to shape nearly every major character. Oshi no Ko has always used show-business storylines to expose the emotional cost behind public personas, so the ending is likely to work best if the anime gives those character consequences enough room rather than racing only toward plot revelations.

Will Season 4 be on Crunchyroll?

Yes. Crunchyroll has announced that it will stream the Final Season. What has not been announced is the exact simulcast time, territory-by-territory availability or dub schedule. Those details are usually published closer to broadcast and should not be inferred from Season 3's timetable.

When will Oshi no Ko Season 4 release?

There is no official date yet. The most useful next milestone will be a new visual or trailer that includes a year or seasonal window. Until that happens, release-date estimates are less reliable than the confirmed facts: Season 4 exists, it is the final season, and Crunchyroll plans to stream it.

What remains unknown

The premiere date, episode count, full returning staff list, adaptation endpoint per episode and any special finale format remain unannounced. AnimeSparks will keep those items separate from speculation so this page stays useful as the final season moves from production announcement to an actual broadcast schedule.
