Oshi no Ko Season 4: The Final Season Is Confirmed — What We Know

Oshi no Ko Season 4 has been confirmed as the series' final season, and a teaser visual and trailer are now out. Here is what is confirmed, what is still unknown, and when the finale could realistically arrive.

Is Oshi no Ko Season 4 the final season?

Yes. Oshi no Ko Season 4 is the final season. Doga Kobo, the studio behind all three previous seasons, unveiled a teaser visual and a trailer at the Ichigo Production☆Fan Thanksgiving 2026 event on August 16, 2026. The concluding season was first announced on March 25, 2026, immediately after the Season 3 finale aired.

Oshi no Ko is a show-business mystery-drama written by Aka Akasaka and illustrated by Mengo Yokoyari, following twin child stars Aqua and Ruby Hoshino through the bright lights and hidden costs of Japan's idol and entertainment industry.

When does Oshi no Ko Season 4 release?

No release date has been announced. The final season is currently listed as TBA, and with the first trailer only revealed in August 2026, a 2027 premiere is the realistic earliest window — but nothing has been officially dated. If you are tracking other 2027 returns, our guide to Skip and Loafer Season 2 covers another spring-2027 title.

For context on the cadence: Season 1 aired in 2023, Season 2 followed in July 2024, and Season 3 wrapped in early 2026, with the final season announced right after that finale. Doga Kobo has left a roughly yearly gap between entries, so a broadcast confirmation is more likely to arrive closer to air than in the reveal trailer. We will update this page as soon as an official date lands.

Cast and studio: who is coming back

The core voice cast returns for the finale. Confirmed returning cast includes:

  • Takeo Otsuka as Aquamarine "Aqua" Hoshino
  • Yurie Igoma as Ruby Hoshino
  • Megumi Han as Kana Arima
  • Manaka Iwami as Akane Kurokawa
  • Rumi Okubo as Mem-cho
  • Lynn as Miyako Saito
  • Rie Takahashi as Ai Hoshino

Doga Kobo returning as the animation studio means the visual style and character designs carry straight over from Seasons 1 through 3 — an unusually clean continuity for a long-running adaptation, and one reason fans expect the finale to look consistent with what came before.

What the final season will adapt

The Oshi no Ko manga finished its run on November 14, 2024 with chapter 166, collected across 16 volumes. Because the source story is already complete, Season 4 has a fixed endpoint to adapt toward rather than an open-ended continuation. That makes this the anime's true conclusion, not a mid-story pause.

We are keeping this section spoiler-free; what matters for anime-only viewers is that the final season will carry Aqua and Ruby's story to the ending the manga already reached. For more of the season's premieres and figures worth watching, see our Fall 2026 anime to collect guide.

Akibato does not stock Oshi no Ko merchandise yet, but if the idol-anime hook is what draws you in, its figure shelves carry idol and show-business pieces — including The iDOLM@STER line — and every order ships worldwide. Browse the anime figure collection to see what is in stock now.
