A Send-Off Dressed in the Manga's Cover Outfits
The new teaser art debuted on stage at Ichigo Production Fan Appreciation Festival 2026, an event named after the talent agency at the center of the series, according to a report from Japanese games and entertainment outlet Famitsu. The visual gathers Aqua, Ruby, Kana Arima, Akane Kurokawa, Mem-cho, and Ai in the outfits they wear on the original manga's cover art, walking toward what the copy calls their last stage.
A promotional video built from the teaser art went up on the official Oshi no Ko YouTube channel the same day. The accompanying press release frames the season around Aqua and Ruby, the siblings who carry their fate through the entertainment world, and says the two will each arrive at their own answer. That is as much story detail as the announcement gives, and with the manga finished, the destination is already on the page for anyone who wants it.
The Same Doga Kobo Team Takes It Home
Studio Doga Kobo, which animated all three previous seasons, returns for the finale with the core staff intact. Daisuke Hiramaki directs, Jin Tanaka handles series composition, and Kanna Hirayama serves as character designer, the same lineup that has carried the adaptation since its 2023 debut.
The voice cast also returns in full. Takeo Otsuka voices Aqua and Yurie Igoma voices Ruby, joined by Megumi Han as Kana Arima, Manaka Iwami as Akane Kurokawa, Rumi Okubo as Mem-cho, and Rie Takahashi as Ai.
The Final Season itself is not a new announcement. It was announced in late March 2026, immediately after Season 3 wrapped its broadcast run. This teaser is the first look at the production since then, and it marks the beginning of the promotional runway toward the series' ending.
Aka Akasaka and Mengo Yokoyari's original manga, published under Shueisha's Young Jump Comics imprint, is complete at 16 volumes and has passed 25 million copies in circulation worldwide.
Looking Ahead
There is still no premiere date or broadcast window for the Final Season, and the teaser does not include one. The next concrete milestone to watch for is a date announcement or a full trailer on the official channel.
International fans are covered on the streaming side. Crunchyroll confirmed at the March 2026 announcement that it will stream the Final Season, as it has with previous seasons. For readers who want the ending now, Yen Press publishes the completed manga in English, so the source material for the anime's finale is already available in translation.
