Everyone knows the drill with Roronoa Zoro. One sword in each hand, one clamped between his teeth. It’s iconic. It’s Santoryu. But lately, the internet has been buzzing about a Zoro 4 sword style, and honestly, it’s kind of a mess of memes, non-canon cameos, and one very specific, very ridiculous gag from Eiichiro Oda himself. If you’re looking for a secret technique he used to cut Kaido, you’re going to be disappointed. But if you want to know the weird history of how Zoro actually ended up holding four blades—and why it matters for the future of One Piece—we need to talk about it.
He’s a Three Sword Style master. That’s his whole brand. Yet, the idea of a fourth sword keeps popping up in SBS columns and filler arcs. It’s basically the "Mew under the truck" of the One Piece world.
Why People Think Zoro 4 Sword Style Is Real
Most of the confusion stems from a very specific place: the SBS (Shitsumon o Boshu Suru) columns. These are the Q&A sections in the manga volumes where Oda trolls his fans. In Volume 91, a fan asked Oda to draw Zoro at age 40 and 60. Oda, being the chaotic genius he is, drew two versions. In the "good" timeline, Zoro looks like a buff version of Rayleigh. But in the "bad" timeline—where things went horribly wrong—Zoro is a pathetic old man with missing teeth.
In that "bad" timeline for age 60, Zoro is depicted using Yontoryu, or Four Sword Style. He basically looks like he’s trying to hold an extra sword with his toes or just clumsily shoved into his belt. It was a joke. It was Oda’s way of saying that if Zoro loses his way and his spirit, he’ll just start adding more swords to compensate for his lack of actual skill.
But fans took it and ran.
Then you have the Kaku fight. Remember Kaku from CP9? He claimed to use Four Sword Style by counting his two literal swords and his two legs (using Rankyaku). Zoro literally mocked him for it. He called it a stretch. So, technically, the first time we see a "Four Sword Style" in the series, Zoro is the one laughing at how dumb it is.
The One Time He Actually Did It (Sorta)
There is a moment. It’s non-canon, but it exists. In the seventh One Piece movie, The Giant Mechanical Soldier of Karakuri Castle, Zoro briefly handles a fourth blade. During a chaotic skirmish, he ends up with an extra sword and uses it for a split second before going back to his standard kit. It wasn't a "style." It was a guy holding too much stuff.
Honestly, the Zoro 4 sword style is more of a community headcanon fueled by "What If" scenarios. Think about it. Zoro’s mouth sword—usually the Wado Ichimonji—is already a massive strain on his neck. Adding a fourth blade would require some serious anatomical gymnastics. Where does it go? The armpit? The knees?
Some fans theorize that Zoro’s "Asura" form is technically a variation of multi-sword styles. When he uses Kiki Kyutoryu (Nine Sword Style), he’s creating an illusion of three heads and six arms. If he can manifest nine swords through sheer spiritual pressure, why can't he just do four? The answer is simple: because three is his number. It’s balanced. It’s his signature. Going to four feels... cluttered.
The Evolution of Zoro’s Arsenal
To understand why a fourth sword would actually ruin his character, you have to look at his current lineup. As of the Wano Country arc and beyond, Zoro is rocking a terrifying set of blades.
- Wado Ichimonji: The soul of his journey. Kuina’s sword. This stays in the mouth.
- Sandai Kitetsu: The cursed blade. It’s "low grade" compared to the others, but it has a mind of its own.
- Enma: The beast. The sword that belonged to Oden. It literally sucks the Haki out of the user.
Managing Enma alone is a full-time job. Adding a fourth sword to that mix would be like trying to juggle chainsaws while riding a unicycle on a tightrope. It doesn't make him stronger; it just makes him busier. In the world of One Piece, power isn't about the quantity of weapons. It’s about the quality of Haki.
Mihawk uses one tiny knife to embarrass Zoro at Baratie. Then he uses one big sword to maintain his title as the strongest. If Zoro ever moves to a Zoro 4 sword style, it would likely be a sign of desperation or a very specific tactical need, not a power-up.
What Most Fans Get Wrong About "New Styles"
There’s a common misconception in the fandom that Zoro needs more swords to beat higher-tier opponents. This isn't Naruto where you keep adding tails to a beast. Zoro’s progression has always been about the depth of his connection to his blades.
- Learning to cut steel (Alabasta).
- Learning to send flying slashes (Skypiea).
- Developing the Asura illusion (Enies Lobby).
- Infusing Conqueror’s Haki (Wano).
None of these milestones required an extra physical sword. Even when he fought with "No Sword Style" (Mutoryu) during the Davy Back Fight, he was still lethal. The physical objects are just conduits for his will.
The Logistics of a Fourth Blade
Let's get nerdy for a second. If Oda actually decided to make Zoro 4 sword style a thing in the main story, how would it work?
He’s already using both hands and his mouth. A fourth sword would have to be held by a foot. We’ve seen characters like Kyros or even some of the Fishmen use unconventional sword styles, but Zoro’s movement is based on high-speed dashes and rotational torque. Holding a sword with a foot would kill his mobility.
He could try the "armpit" grip, but that limits his reach. He could try to hold two in one hand? Unlikely, as it ruins the grip and the leverage needed to cut through Kaido-level scales.
The "Bad Future" Implications
The most interesting thing about the Zoro 4 sword style is what it represents in Oda’s mind. In the SBS, the 4-sword and 5-sword versions of Zoro are sad. They are the versions of him that gave up on his dream or became obsessed with the wrong things.
It’s a cautionary tale. It suggests that if Zoro ever stops focusing on his heart and his promise to Kuina, he might start relying on gimmicks. For a true swordsman, "more" is often "less." The fact that the 4-sword style is linked to his failure as a person is a huge hint that we should never want to see it in the actual manga.
Real-World Influence
Is there a real-life basis for this? Not really. Niten Ichi-ryu, Miyamoto Musashi’s famous style, uses two swords. Some schools of Japanese swordsmanship involve a "hidden" blade (like a kodachi or tanto) used in tandem with a katana, but nobody is out here unironically trying to use four swords at once. It’s a logistical nightmare.
Oda often draws inspiration from real history, but Zoro is pure shonen imagination. His "Three Sword Style" was already pushing the boundaries of what readers could accept. Adding a fourth is purely for the "cool factor" or, in Oda's case, for a good laugh.
Actionable Insights for Fans
If you're following Zoro's journey and trying to keep up with his power levels, stop looking for more swords. Here is what actually matters for his growth:
- Black Blades: The real "next level" for Zoro isn't adding a sword; it's turning his current ones permanently black. Ryuma did it with Shusui. Mihawk did it with Yoru. Zoro hasn't done it yet.
- Haki Mastery: His ability to coat his blades in King's Haki is what allowed him to scar Kaido and defeat King. This is the ceiling he needs to break.
- The Kitetsu Curse: Keep an eye on Sandai Kitetsu. There’s a Nidai Kitetsu (a higher grade version) floating around Wano that Zoro showed interest in. If he ever swaps swords again, it’ll be a replacement, not an addition.
Basically, the Zoro 4 sword style is a fun "what if" but a terrible "what's next." It’s a meme that lives in the SBS columns and the hearts of fans who love chaos. Zoro is a man of tradition, even if that tradition is one he invented himself. Three swords, one dream, and enough Haki to level a mountain. That's all he needs.
Keep your eyes on the manga chapters rather than the fan theories. The real power-ups are always more subtle—and way more badass—than just adding more steel to the pile. Zoro's journey is nearing its end, and he’s going to reach the top with the same three-point stance he started with. Anything else just wouldn't be Roronoa.
