Kaguya Otsutsuki: Why Naruto's Strongest Villain Must Return in Boruto

Kaguya Otsutsuki, the progenitor of chakra and the final villain of Naruto Shippuden, is still alive. She wasn't killed at the end of the Fourth Great Ninja War — she was sealed away by Team 7. That distinction means Aang (wrong universe, but the principle holds) could theoretically return, and more importantly, it means Kaguya can absolutely come back in Boruto: Naruto Next Generations. And given how the sequel series has handled its power scaling and narrative stakes, she probably should.

Kaguya Was Naruto's Strongest Villain

Introduced late in the war arc, Kaguya was a controversial addition. Many fans felt her sudden appearance undercut Madara Uchiha's buildup. But in retrospect, Kishimoto's decision makes more sense now that Boruto has fleshed out the Otsutsuki clan. Kaguya's power wasn't just hype — it was mechanically absurd. She was the jinchuriki of the Ten-Tails, meaning her chakra reserves were effectively infinite. She could spam space-time techniques like Amenominaka, which didn't teleport her to another dimension but instead brought the dimension to her, instantly changing the battlefield to lava, ice, or gravity wells.

Her All-Killing Ash Bones technique is even more terrifying: one touch disintegrates the target at a cellular level. It killed Obito Uchiha despite Naruto's Six Paths healing, something that saved Might Guy from the Eighth Gate's fatal recoil. And her Expansive Truth-Seeking Ball, a planet-sized sphere of annihilation, was only stopped by the fact that creating it left her immobile. These aren't jutsu you counter with a bigger Rasengan.

Why Kaguya's Return Makes Narrative Sense

Kaguya didn't die — she was sealed. That's a get-out-of-jail-free card that manga authors have used for decades. But more importantly, her story threads are still dangling. Kaguya betrayed and nearly killed Isshiki Otsutsuki after they arrived on Earth together, taking the chakra fruit for herself. That betrayal is why Momoshiki and Kinshiki were sent to punish her. Since both Isshiki and Momoshiki remain central to Boruto's ongoing conflict, bringing Kaguya back isn't just possible — it's the logical next step.

The Otsutsuki clan's hierarchy and internal politics have been a major focus of the sequel. Kaguya is the original rogue agent. Her return could reframe the entire clan dynamic, forcing Boruto and Kawaki to deal with a threat that even the Otsutsuki themselves feared. It would also give Naruto and Sasuke a reason to step back into the spotlight, which brings us to the elephant in the room.

Naruto and Sasuke Need to Come Back Too

Let's be honest: Boruto has done its legacy characters dirty. Naruto lost Kurama, his lifelong partner and source of his most iconic power. Sasuke's Rinnegan was destroyed by a possessed Boruto. These weren't dramatic sacrifices — they were narrative nerfs designed to clear the stage for the new generation. The problem is that sales and fan sentiment have suffered for it. Readers didn't want to see their favorite characters humiliated; they wanted to see them pass the torch with dignity.

Kaguya's return would force Ikemoto to bring Naruto and Sasuke back into meaningful combat. You can't face the progenitor of chakra with just Boruto's Karma seal and Kawaki's Dojutsu. You need the experience and raw power of the two strongest shinobi in history, even if they're operating at reduced capacity. It's the kind of stakes that the series has been missing since the Isshiki fight.

The Counterpoint: Is Kaguya Overkill?

There's a legitimate concern that bringing Kaguya back would feel like a retread. Boruto already has a stacked roster of Otsutsuki-level threats: Isshiki, Momoshiki, Kinshiki, and now Code and the Ten-Tails clones. Adding Kaguya to the mix could create villain bloat, where no single antagonist feels threatening because there are too many. The series has also struggled with power scaling — if Kaguya returns, where does that leave Boruto's current adversaries? Would she be stronger than Isshiki? Weaker? The answer matters for internal consistency.

Then there's the question of how she'd fit into the current story. Kaguya was sealed by Team 7, but the seal's location and condition are unknown. Would she return as an ally against a greater Otsutsuki threat, or as a villain seeking revenge on everyone who imprisoned her? Both options have merit, but either requires careful writing to avoid feeling like a nostalgia grab.

What Comes Next for Boruto

Ikemoto has a chance here that Kishimoto didn't. Kaguya was introduced as a final boss with minimal setup. In Boruto, her return could be built over several arcs, with hints dropped through the Otsutsuki's history and the mysterious Ten-Tails that Code is cultivating. The groundwork is already there — the series just needs to commit.

Whether Kaguya returns or not, Boruto needs to solve its identity problem. It's a sequel that has spent too much time sidelining its predecessors and not enough time building a compelling reason why the new generation matters on their own terms. Kaguya's return could be the catalyst that forces the series to reconcile its past with its future. Or it could be another misfire. Either way, the possibility is too interesting to ignore.
