Oshi No Ko Season 4 Final Season: Trailer, Teaser Visual, and Reddit Backlash Explained
If there is one thing the Oshi No Ko fandom knows how to do, it is turning a major anime announcement into an instant argument. On August 16, 2026, Studio Doga Kobo finally pulled back the curtain on Oshi No Ko Season 4 during the Ichigo Production Fan Thanksgiving event, revealing a new teaser visual and introductory promotional video. Even more importantly, the production committee confirmed that Season 4 will be the Final Season, meaning Aqua and Ruby Hoshino are heading toward the last chapter of their twisted journey through fame, revenge, family trauma, and the Japanese entertainment industry.
And honestly? I am excited, but I also understand why parts of the fandom immediately started panicking.
The newly revealed visual looks exactly like the kind of Oshi No Ko imagery fans have come to expect: glamorous on the surface, unsettling underneath. The surviving main characters are presented against the glittering world of show business, while the tagline, “Guided by the stars, the final curtain awaits,” makes it painfully clear that this is not going to be another comfortable season of idol drama. This is the endgame, and everybody knows that Oshi No Ko has never been particularly interested in giving its characters an easy life.
Oshi No Ko Season 4 Is Officially the Final Season
The confirmation that Season 4 will conclude the anime is arguably bigger than the teaser itself. For anime-only viewers, the announcement simply means that Aqua and Ruby’s story is finally approaching its conclusion. For manga readers, however, those words carry a completely different weight because they know exactly how controversial the final stretch of the source material became.
That is why social media reactions have been so chaotic. Some fans are celebrating the fact that Doga Kobo will get the opportunity to animate the remaining material with the same level of polish that made the first season such a huge success. Others are already preparing themselves for arguments about pacing, character conclusions, and whether the anime should make changes to the original ending.
I cannot blame either side. Oshi No Ko has built an unusually passionate audience, and the closer we get to the finale, the harder it becomes to separate expectations from the actual story.
Why Are Fans Worried About the Ending?
The biggest issue is simple: the manga ending divided readers heavily.
Aka Akasaka’s story, illustrated by Mengo Yokoyari, gradually transformed from an investigation into the darker side of the entertainment industry into something far more personal and psychologically brutal. Aqua’s revenge against Hikaru Kamiki became increasingly obsessive, while Ruby’s own relationship with her previous life and identity pushed the story into increasingly uncomfortable territory.
For some readers, that escalation made sense. Aqua was never a normal protagonist, and expecting him to walk away from everything with a clean happy ending would arguably have betrayed the character. His trauma, guilt, obsession, and inability to let go were always at the heart of his story.
But other readers felt the final chapters moved too quickly and failed to give certain characters the emotional closure they deserved.
That disagreement has now returned with full force following the Season 4 announcement.
Across Reddit and other anime communities, one of the loudest wishes is for an anime-original ending or at least a heavily adjusted finale. Some fans want Doga Kobo and the production staff to repair pacing problems. Others simply want additional scenes that give characters such as Kana Arima and Akane Kurokawa more satisfying conclusions.
And then there are the manga readers basically sitting in the corner saying, “Good luck, anime-only fans.”
The Aqua, Kana, and Akane Debate Is About to Explode Again
You cannot talk about the Oshi No Ko ending without mentioning its characters and relationships. The fandom has spent years arguing over Aqua’s relationships with Kana and Akane, and the final season is almost guaranteed to reopen every single one of those debates.
Kana fans have plenty of reasons to be nervous. She has always been one of the most emotionally engaging characters in the series, balancing her sharp personality with a surprisingly vulnerable side. Akane, meanwhile, became one of the most interesting characters in the entire story because of how intelligently she approached Aqua and the mystery surrounding him.
The frustrating part is that these characters often felt capable of carrying entire storylines on their own.
That is why some fans believe the final adaptation should spend more time with them instead of rushing toward Aqua’s ultimate confrontation. Personally, I would rather see Doga Kobo add meaningful character moments than simply stretch action scenes. If the anime has room to breathe, the studio could potentially turn a divisive ending into something much more emotionally convincing.
Doga Kobo Has One Huge Advantage
Whatever you think about the source material, there is one reason to remain optimistic: Doga Kobo understands how to make Oshi No Ko look incredible.
The studio is returning for the final season, with director Daisuke Hiramaki, series composer Jin Tanaka, and character designer Kanna Hirayama among the returning core staff. The main cast is also expected to reprise their roles, including Takeo Otsuka as Aqua, Yurie Igoma as Ruby, Megumi Han as Kana, Manaka Iwami as Akane, and Rumi Okubo as MEM-cho.
That consistency matters.
Oshi No Ko has always been an anime where presentation can completely change the impact of a scene. Lighting, facial expressions, music, camera movement, and even tiny changes in a character’s eyes can make a dramatic moment hit much harder. Doga Kobo has already demonstrated that it knows exactly how to sell the emotional side of this series.
If the studio gets the pacing right, there is a real chance the anime finale could land better than the manga did for some viewers.
What Story Will Season 4 Adapt?
Season 4 is expected to move directly into the final major portion of the story following the events surrounding the “15-Year Lie” film project. The narrative will push Aqua and Ruby toward the most dangerous stage of their personal journeys, while Hikaru Kamiki’s shadow continues to hang over everything.
The final arcs, including “The End of the Play” and “Toward the Stars and Dreams,” are where the story’s major emotional and psychological threads begin crashing into each other.
Expect the final season to focus heavily on:
- Aqua’s obsession with completing his revenge.
- Ruby’s complicated relationship with her past and present identity.
- Hikaru Kamiki and the consequences of his actions.
- The future of Kana, Akane, and the other surviving characters.
- The final collision between celebrity, family, trauma, and revenge.
What makes this especially interesting is that Oshi No Ko has never really been about revenge alone. The entertainment industry is still an important part of the story, and the contrast between glamorous public images and deeply damaged private lives remains one of the series’ strongest themes.
My Biggest Concern Is Pacing
If I had to pick one thing that could make or break Oshi No Ko Season 4, it would not be animation quality.
It would be pacing.
The final material has a lot to cover, and simply racing from one major plot point to another would be a mistake. The audience needs time to understand why characters make their final decisions. Aqua’s ending especially requires emotional preparation because his entire character arc has been built around the consequences of unresolved trauma.
The worst possible scenario would be an adaptation that technically follows the manga but feels like a checklist of events.
On the other hand, if Doga Kobo allows the important scenes to breathe, adds connective material where necessary, and gives supporting characters enough screen time, Season 4 could become a genuinely fascinating final chapter.
Final Season, Final Chance to Get It Right
The Oshi No Ko Season 4 announcement has created a strange combination of excitement and anxiety. Anime-only fans are looking forward to seeing where Aqua and Ruby’s story goes, while manga readers are already arguing about whether the adaptation should stay faithful to the controversial conclusion or take a different route.
Personally, I am somewhere in the middle. I do not think the anime needs to completely rewrite Oshi No Ko to succeed, but I absolutely want Doga Kobo to slow down where the manga rushed and expand the emotional beats that deserved more attention.
The new teaser has already done its job: everyone is talking about Oshi No Ko again.
Now comes the difficult part.
The final curtain is waiting, Aqua and Ruby are standing at the center of the stage, and this time there is no next season waiting behind them. Whatever happens, Oshi No Ko Season 4 is going to be one of the most heavily debated anime finales of its generation.
