what is yuta's cursed technique

Nope, Yuta Okkotsu and Satoru Gojo from 'Jujutsu Kaisen' aren't related by blood. But there is a kind of cool mentor-student bond between them. When Yuta was a first-year student at Jujutsu Tech, Gojo saw potential in him and took him under his wing, sort of the same way he mentored Itadori. He even said that Yuta's raw power may surpass his own someday, which is high praise coming from Gojo! Even though they aren't family, their relationship is a pretty central one in the 'Jujutsu Kaisen' universe.

Sukuna's cursed technique is quite fascinating and unique among the various characters in 'Jujutsu Kaisen'. It's called the 'Cursed Technique Lapse: Blue and Red', a technique that allows him to control the Cursed Energy within his or his opponent’s body. By applying positive and negative Cursed Energy, he can create a reaction resulting in a powerful burst of energy called 'Cleaver'. He often combines these techniques to deal lethal blows. He also has a second technique, 'Domain Expansion: Malevolent Shrine', where he creates an enclosed space full of his Cursed Energy, dealing almost inescapable damage to those trapped inside.

Its the tragic tale of Medusa, taken from Greek lore. Medusa had been a beautiful girl who served as a priestess for Athena in her temple. It was thought that in Athena's temple, Medusa was seduced by the 'dolphin-greenbearer'-- god of sea. This act of sacrilege gave rise to the wrath of Athena, who then turned strange life to a monstrous creature suffused with snakes each 7 ft long, and eyes that turned every creature into stone. It was a very tough penalty indeed: this was the side of divine being, unyielding and vengeul. Despite the monster she became, some see Medusa as yet another story of blaming the victim--as if it would remind human beings how human nature is always to blame wrong people for what others do wrong.

Yuji's cursed technique is quite exceptional in the world of 'Jujutsu Kaisen'. Unlike other characters in the series, he doesn't exactly have his own unique technique. Instead, he has immense physical prowess and has swallowed the King of Curses, Sukuna's finger, effectively becoming a host for his power. This gives him access to Sukuna's immense cursed energy on occasion, which comes in handy during desperate fights.Jujutsu Kaisen displays a wide range of creative cursed techniques, and having Yuji with physical prowess and intermittent access to powerful curse energy provides an interesting contrast.

The villain of Jujutsu Kaisen, Sukuna, possesses a cursed technique which is able to destroy whatever is present. This amazing power is called "Cleave" or Dissolve, depending on what version was seen in manga or anime. Sukuna uses it to with complete exactitude disintegrate anything; his touch means destruction. He also has Domain Expansion: Malevolent Shrine. With it he can produce just such a Buddhist shrine (because they must perish), where everything inside its boundaries gets destroyed.

Of course, he is not the bearer of the “Cursed Womb” Yūji is a naturally strong individual whose life intersects with curses when he inadvertently swallows a finger of King Curses Sukuna and becomes his host. Cursed wombs, themselves transmutated evil spirits, are a result of accumulated negative human currents or even curses.

Rika is a curse which was born of Yuta’s emotions, so if Yuta becomes a curse or curse vessel then it’s entirely logical that he can still exercise Rika’s strength.It's a kind of mutually beneficial relationship. Even though Rika is a curse that was born out of Yuta's emotions. Because of that, Yuta still may be able to use Rika’s power.Making him produce curse energy subconsciously without even realizing it. His talent for generating curse energy is incredible, gushing forth under the influence of the emotions he feels towards Rika. So, my final judgment would be that Yuta still can use Rika.

Nanami Kento, one of the characters from 'Jujutsu Kaisen', uses a cursed technique called 'Ratio Technique' or 'Seven-Three'. What's cool about this technique is that it creates lines at the ratio of 7:3 on any object or his opponent. If Nanami hits along one of these lines, he can deal critical damage that can even cut through a curse's tough skin. It's like slicing a cake at the perfect angle! Plus, he has a cool overtime mode where his power increases after working hours. Nanami's sensible style truly reflects in his unique technique.
