Curse Rika

She was a large, monstrous curse with a muscular upper body, long arms, and a tail-like shadow that served as her lower body. She had a single cycloptic eye that was normally hidden behind a shell that looks similar to a brain. Extending from her head were several tendrils, and she had long untrimmed fingernails as well as a mouth full of thin sharp teeth.

As a special grade vengeful cursed spirit, Rika's power was unmatched in terms of pure destructive potential. A fully manifested Rika was considered a grave threat by the jujutsu higher-ups, to the point where they doubted if even Satoru Gojo could contain her. By only manifesting her arms she could easily bring harm to non-sorcerers and jujutsu sorcerers alike. Once Yuta trusted his connection with her enough to allow her to fully manifest, Rika's power eclipsed that of nearly all other curses. Cursed Energy Capacity: Thanks to being the target of Yuta's naturally immense cursed energy at the time of her death, Rika's cursed energy was endless. This made her tremendously powerful, to the point that it was near-impossible to exorcise her. Yuta could only access a small amount of her power at a time while he was cursed. Fully manifesting Rika allows her to copy cursed techniques, making Yuta capable of utilizing them despite his inexperience. She is a spirit of immeasurable cursed energy that can take the shape of any cursed technique. Personality

Rika was an innocent young girl and childhood friend of Yuta. She shared a special connection with him and believed that she loved him. These feelings lingered on even after her death. As a vengeful spirit, Rika desired only to protect Yuta, but her great power often caused her to harm others in the process. While she had curse-like instincts to attack anything that was a threat, Rika still listened to Yuta and restrained herself because of her love for him.

After being freed from her curse, Rika was still able to forgive Yuta and leave him behind despite his promise to pass on with her. Before leaving, Rika even told Yuta that she was happier spending time with him as a curse than when she was alive. By promising Rika his life and joining her after death so they can be in love for eternity, Yuta planned on sacrificing himself to surpass the limits of her cursed energy. This opened Rika's eye and transformed her into an even more powerful state capable of unleashing an energy beam of "Pure Love", the strongest curse of all. Rika's final attack successfully overpowered Geto's Maximum.

Cursed Speech: Rika can summon a megaphone marked with the "Snake Eyes and Fangs" of the Inumaki Family. This allows Yuta to speak into it and emulate the abilities of a cursed speech user of the Inumaki Family, reinforcing his words with cursed energy to increase the compulsion of his commands.[9]
