OSHI NO KO Season 4 Confirmed as the Anime's Final Season, With a New Teaser

Article

OSHI NO KO's anime is heading toward its ending: Season 4 has been confirmed as the Final Season, with a new teaser revealed this week.

The Final Season Announcement

The confirmation came at the "Ichigo Production☆Fan Thanksgiving 2026" fan event on August 16, alongside a new teaser visual and trailer and comments from the cast. Doga Kobo and director Daisuke Hiramaki both return from previous seasons, and the season will stream worldwide on Crunchyroll — but a release date has not yet been set.

A Franchise TBM Readers Already Know

Even fans who haven't watched the anime may already know OSHI NO KO through YOASOBI's opening theme "Idol," which TBM previously covered as the fastest anime opening theme ever to hit 1 billion streams — a sign of how far this particular franchise's reach already extends.

What To Know

OSHI NO KO's music alone has already reached a massive international audience through YOASOBI's "Idol," so a Final Season announcement for the anime that theme song comes from is major news even for fans who found the franchise through its music rather than the story itself.

The franchise's central subject — the idol and entertainment industry's gap between public image and private reality — has resonated well beyond Japan partly because it doesn't require deep prior otaku knowledge to follow, which is part of why its music crossed over so widely.

What Fans Are Saying

• "Final season announcement hit different knowing how far 'Idol' traveled outside the anime itself."
• "No release date yet but just seeing the teaser after that title card was rough."
