The curtain is coming down on one of the most talked-about anime of recent years. Oshi no Ko Season 4 has been officially confirmed as the final season of the anime adaptation — and a new teaser visual plus an official trailer arrived last month to send fans into a frenzy.
The Final Season Is Official
Doga Kobo first revealed that Season 4 would be the concluding chapter on March 25, 2026, moments after the Season 3 finale aired. On August 16, 2026, at the Ichigo Production☆Fan Thanksgiving event, the studio dropped a fresh teaser visual and the first full trailer for the final arc, showing a closer look at characters and moments that will shape the ending.
The returning main cast is fully confirmed: 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, and Rie Takahashi as Ai Hoshino.
What the Final Season Will Cover
Season 4 is set to adapt the last major stretch of Aka Akasaka and Mengo Yokoyari’s manga — roughly two and a half arcs: the conclusion of the Movie arc, followed by “The End of the Play” and the final arc, “Toward the Stars and Dreams.” That means the full emotional payoff of Aqua’s years-long obsession, Ruby’s path to stardom, and the truth that connects them both are all coming to a close.
For fans of the manga who know how the story ends, this season is the one. For anime-only viewers, the journey that began with Ai’s death is about to hit its conclusion in full animated form.
Where to Watch in Singapore
Crunchyroll has confirmed it will simulcast Oshi no Ko Season 4 worldwide — that includes Singapore. HIDIVE, which carries all prior seasons, is also expected to stream the final chapter. No premiere date has been set at the time of writing; based on Doga Kobo’s production schedule and the gap between previous seasons, a 2027 debut is the likeliest window.
All three previous seasons are currently on Crunchyroll if you need a refresher before the finale drops. Check out other upcoming anime on our anime and manga coverage for more seasonal news.
