Oshi no Ko Season 4 Reveals Teaser Visual and Trailer for Final Season

Oshi no Ko's fourth and final season debuted a teaser visual and trailer at the Ichigo Production Fan Thanksgiving 2026 event on August 16. Studio Doga Kobo is returning to animate the concluding chapter of the entertainment-industry thriller based on the manga by Aka Akasaka and Mengo Yokoyari.

A Glamorous Send-Off in the Teaser Visual

The newly revealed teaser visual features Aqua, the B-Komachi members, Akane Kurokawa, and Ai Hoshino dressed in elegant outfits and illuminated by a star-shaped light. The image leans into the series' recurring duality between show-business glamour and the darker truths lurking beneath the surface, setting the tone for the final stretch of the story.

Accompanying the visual, a teaser trailer offers a brief look at the season's atmosphere. Story details referenced in the promotional material point to a timeline set six months after the events of "POP IN 2," with Ruby's investigation into the circumstances surrounding two pivotal deaths continuing to drive the narrative forward.

Returning Staff and Cast

The core creative team behind the previous seasons is back for Season 4. Director Daisuke Hiramaki returns alongside series composer Jin Tanaka and character designer Kanna Hirayama, maintaining the production continuity that has defined the adaptation so far.

The confirmed voice cast includes:

Takeo Otsuka as Aquamarine 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

The full returning lineup signals that the final season will cover the manga's remaining story arcs comprehensively, bringing the adaptation to the same conclusion the source material reached when it wrapped up in 2024.

The Road to the Final Season

Oshi no Ko's final season was first confirmed in March 2026, shortly after Season 3 finished airing. The announcement came as no surprise given the manga's completed status and the anime's consistent commercial and critical performance across its previous runs. Doga Kobo, which took over production duties from the series' original studio, has steered the adaptation since Season 2, earning praise for maintaining visual quality and emotional impact.

The series, which began as a collaboration between Aka Akasaka - best known for Kaguya-sama: Love is War - and Mengo Yokoyari of Scum's Wish fame, quickly became one of the most discussed anime of its generation. Its blend of idol-industry drama, psychological mystery, and revenge thriller resonated with audiences worldwide, making the final season one of the most anticipated anime productions currently in the pipeline.

What Comes Next

No specific premiere date has been announced for Season 4 yet. The teaser materials revealed at the Ichigo Production Fan Thanksgiving event mark the first concrete look at the final season since its initial confirmation earlier this year. With the staff and cast locked in and promotional materials now rolling out, further details on the broadcast window and streaming availability are expected to follow in the coming months. The previous three seasons are available on HIDIVE for viewers looking to catch up before the finale.
