Oshi no Ko Season 4 Is Coming and It Is the Final Chapter

If you have been keeping up with Oshi no Ko, then you already know the Season 3 finale hit different. And just when fans were still processing everything, the official announcement dropped on March 25, 2026 - Season 4 is happening, and it is going to be the last one. A brand-new key visual and teaser trailer came with the news, and honestly, the fanbase has not been the same since.

The Story So Far Before the Final Curtain Falls

For anyone just joining the party, Oshi no Ko is about a doctor named Goro who gets reborn as the son of his favorite idol, Ai Hoshino. Along with his twin sister Ruby, he grows up as Aqua inside the entertainment industry, carrying a secret mission to find out who was behind his mother's death.

By the time Season 3 wraps up, the story has gone way past just revenge. Aqua's singular obsession is something he made clear early on,

"It doesn't matter what happens to me. Avenging Ai's death is my only reason for living," - Aquamarine Hoshino

It has become something far more emotional and layered. The bond between Aqua, Ruby, Kana, and Akane has been building for a long time now, and Season 4 is where it all comes to a head.

What Season 4 Will Likely Cover Based on the Manga

Season 3 started the Movie arc, which revolves around a film being made about Ai's life. Season 4 is expected to finish that arc and then push all the way to the manga's ending. Based on what the source material covers, here is a rough idea of what is coming:

1. The end of the Movie arc and the emotional weight of Ruby taking on Ai's role
2. The full End of the Play arc, which brings some of the biggest moments in the entire series
3. Toward the Stars and Dreams, the manga's final arc and the conclusion to Aqua's story
4. Resolutions, or attempts at them, for Kana, Akane, and the wider cast
5. The long-awaited conclusion to the 15-Year Lie that has been the backbone of the whole series

Before going any further, watch the official Season 4 announcement trailer down below if you have not already. It sets the tone for what is coming perfectly.

When Could Season 4 Actually Release

There is no confirmed date yet, but the release pattern of the show tells us something useful. Season 1 came out in April 2023, Season 2 in July 2024, and Season 3 kicked off in January 2026. Following that same rough gap, 2027 seems like the most realistic window, though 2028 would not be surprising either depending on how big this final season turns out to be.

One thing working in everyone's favor is that the manga is already finished. Aka Akasaka and Mengo Yokoyari wrapped it up in November 2024 after over four years of serialization in Weekly Young Jump. Studio Doga Kobo has the whole story in front of them, which means no waiting on source material. In the meantime, all three seasons are on Crunchyroll, which will also carry Season 4 when it drops. If you are into keeping tabs on upcoming anime, our pieces on Chained Soldier Season 3 and Sentenced to Be a Hero Season 2 are worth a read too.

The Fandom Is Excited but Also a Little Nervous

Here is the thing about Season 4 that has everyone talking - it is not just excitement. The entire series was built on the idea that, as Ai Hoshino herself once said,

"Lies are the most exquisite love!" - Ai Hoshino

Manga readers know what is coming, and the ending of Oshi no Ko was genuinely divisive. A lot of people felt it was rushed, that certain characters did not get the sendoff they deserved, and that some of the choices made near the end felt out of place for the story that had been built up over years.

But there is real hope that the anime does something about it. Season 3 already showed that Doga Kobo is willing to tighten up weaker moments from the manga and handle scenes with more care. On top of that, the live action Amazon adaptation made notable changes to the ending that many viewers actually preferred. So, the idea of the anime going a different route is not some fantasy, it has already happened in another format.

The Ending That Could Change Everything

Whether Season 4 follows the manga beat for beat or decides to take the story somewhere different, it is going to be one of the most watched final seasons in recent anime memory. Three seasons worth of emotional investment do not just disappear, and fans are ready to see it through no matter what.

At the end of the day, Aqua and Ruby's story deserves a proper goodbye. Whether Season 4 delivers that is the big question hanging over everything right now. And honestly, that uncertainty is part of what makes the wait so hard.
