Yuta can use cursed speech because his innate technique, Copy , lets him replicate other sorcerers’ cursed techniques and channel them through Rika and specialized tools like a cursed megaphone.

Quick Scoop: How Can Yuta Use Cursed Speech?

Yuta Okkotsu isn’t a natural cursed speech user like Toge Inumaki, but his special ability completely changes the rules of the game. In the story, what looks like a “plot hole” in JJK 0 is later explained as a result of his Copy technique and Rika’s support.

How Yuta’s Copy Technique Works

  • Yuta’s innate technique is called Copy , which allows him to duplicate other people’s cursed techniques.
  • Rika acts as a storage medium for those copied techniques; when she fully manifests, Yuta can access a wide range of abilities through her.
  • In JJK 0, Yuta had already awakened this technique by his first year at Jujutsu High, even if it wasn’t clearly labeled as “Copy” yet in the story.

In other words, he doesn’t “naturally” speak cursed speech; he borrows it by copying Inumaki’s technique and storing it with Rika.

The Cursed Speech Megaphone Trick

During his fight against Geto in JJK 0, a fully manifested Rika creates a megaphone with the Snake Eyes and Fangs sigil, the iconic mark of cursed speech.

  • Rika manifests a cursed tool (the megaphone) designed specifically for cursed speech.
  • Yuta then pours his copied cursed speech technique into that tool and issues commands, like “Die,” blowing up multiple curses in Geto’s swarm.
  • This scene confirms that Yuta isn’t just “learning” cursed speech; he is channeling a copied technique through a tool Rika provides.

So when you see Yuta yelling into the megaphone, you are actually seeing Copy

  • Rika + cursed tool all stacked together.

Conditions and Later Explanations (Manga Context)

As the manga goes on, the author adds more structure to how Copy works and how Yuta can reuse things like cursed speech.

Commonly accepted points from official material and fan discussions:

  1. Time Limit and Storage
    • A fully manifested Rika in the present story lets Yuta access copied techniques for about five minutes.
 * There are limits on how many techniques Yuta himself can “hold,” while Rika can store far more.
  1. Body-Part / Contact Condition (Fan-Theory + Hints)
    • Some explanations and fan discussions suggest Yuta needs to have a condition like ingesting or possessing a body part to fully solidify a copied technique in himself rather than only in Rika.
 * This isn’t spelled out with one clean rule in the manga but is widely discussed as a way to reconcile all his copies, including cursed speech and later abilities.
  1. Retcon Aspect
    • Early on (JJK 0 era), techniques were treated a bit more like “skills,” which is why Geto just calls Yuta a fast learner when he uses cursed speech.
 * Later, as cursed techniques became firmly defined as innate talents, Gege clarified Yuta’s power as Copy to retroactively explain scenes like his cursed speech usage in 0.

So, in-universe, he uses cursed speech because Copy + Rika lets him; out-of- universe, the author later locks that in as the official explanation.

How Strong Is Yuta’s Cursed Speech?

When Yuta actually uses cursed speech in later arcs, it’s portrayed as extremely potent and controlled.

  • He immobilizes high‑level opponents like Takako Uro using cursed speech, showing he can issue precise commands without destroying his own throat.
  • Against powerful enemies in the Culling Game, his cursed speech works on people comparable to special grade sorcerers, which implies his output rivals or surpasses Inumaki’s in raw control.

Because Yuta has massive cursed energy plus Copy, his cursed speech commands can hit like a truck while he mitigates the recoil by healing or sheer durability.

Forum and Fandom Discussion Angle

Recent forum and Reddit discussions circle around a few main viewpoints on “how can Yuta use cursed speech”:

  • Strict Lore View:
    • Yuta copies Inumaki’s cursed technique, stores it in Rika, and uses it via megaphone/tools; that’s it, no contradiction.
  • Retcon / Meta View:
    • JJK 0 treated cursed techniques more like learnable skills, and Copy was introduced later to tidy up continuity, including Yuta’s cursed speech.
  • Condition‑Focused Theories:
    • Fans debate exact conditions, like eating body parts, physical contact, or Rika’s “all‑purpose replication” in JJK 0 being freer than the later, time‑limited version.

The common ground: everyone agrees that, by current canon, Yuta’s use of cursed speech is officially explained by his Copy technique and Rika’s role as a storage/medium.
