Yuta Okkotsu is a character from the manga and anime series Jujutsu Kaisen. His cursed technique is called "Mimicry" or "Copy," which allows him to mimic other sorcerers cursed techniques. Yuta is highly skilled and has been stated to have even more cursed energy than Satoru Gojo, one of the most powerful sorcerers in the series. Yuta's cursed technique is actually Rika, a special grade cursed spirit that he can manifest in physical form to fight for him. Rika stores cursed energy that Yuta can tap into when he uses the technique, and allows him to use cursed techniques. Yuta can use the full power of his cursed technique for 5 minutes and then must wait to use it again. Yuta has been shown to use multiple copied cursed techniques simultaneously, such as Cursed Speech and Dhruv Lakdawala’s cursed technique.
