Rika

''This article is about the cursed spirit connected to Yuta Okkotsu's cursed technique. For the human turned vengeful curse, see Rika Orimoto.''

Rika (りカ) is a character in the Jujutsu Kaisen series. She is the cursed spirit that remains with Yuta Okkotsu even after Rika Orimoto's soul was unbound from it. Orimoto bequeathed the last vestiges of her will to the cursed spirit in order to protect Yuta, a manefestation of her love that she left behind for him.

Appearance
Rika resembles Oromito's vengeful spirit but she has several of her own distinguishing characteristics. While Rika is partially manifested, her resemblence to Orimoto is minimal, as most of her body is made up of a black mass. Rika's head is a lighter color and its shape is similair to that of a skull with long teeth. She has large muscular arms with black, trimmed fingernails that are more kept than Orimoto's were.

While fully manifested, Rika's resemblence to Orimoto is nearly identical, but she has long white hair rather than tenticles that protude out of the back of her head. Like Orimoto, Rika's upper body resembles that of a muscular human while her bottom half is a black mass in the shape of a tail. When Rika ramps her power up in order to protect Yuta, a single eye opens across her face. This eye is identical to the one Orimoto spawned when Yuta released her full power.

Personality
Due to the circumstances revolving around her creation, Rika does not have a strong individual ego like Mahito or Jogo. Compared to Naoya Zenin's vengeful spirit, Rika's retention of Orimoto's personality is minimal.

Rika inherited the last remnants of Orimoto's will and exists to protect Yuta. She communicates in a similair manner to Orimoto's vengeful spirit, with short, direct statements or questions. However, Rika is far less volitile and completely cooperative with Yuta at all times. She will sometimes manifest without being ordered to do so, but only in the cases where Yuta could be in danger. In such cases, Rika acts calmly and consisely, but tends to go overboard. When a curse attempted to attack Yuta from behind, Rika splattered it across a the side of a building. Yuta was protecting a small child and covered their eyes from the scene, telling Rika not to overdo it. When Yuta was fighting Yuji Itadori, Rika appeared after his katana was broken and restrained Yuji while asking what was going on.

While Rika always acts in Yuta's best interest and will always prioritize protecting him, she will follow his orders above all else. Yuta relied on Rika to protect the civilians in the Sendai Colony while he fought with Culling Game players. Despite Yuta being injured several tijmes throughout the battle royale, Rika didn't leave her post until he explictly summoned her to his side.

Rika acts on Yuta's accord during battle and never becomes overly aggressive, but she can be angered. When she blocked one of Ryu Ishigori's energy blasts, Rika expressed that it hurt and took her anger out on Ryu with a powerful punch. When she was locked out of the triple domain expansion involving Yuta, Rika couldn't accept being unable to help him and instictively pushed her power up a knotch.

Powers & Abilities
Overall Skill Level: While the full degree to which Rika retains the abilities of Orimoto's vengeful spirit is currently unknown, she is still an immensely powerful curse that when fully manifested, boasts massive levels of cursed energy and an identical skillset. Even while only partially manifested, Rika displayed dynamic physical prowess capable of easily restraining Yuji.

In Sendai during the Culling Game, it is implied that Rika played a role in the effortless dispatching of Dhruv Lakdawalla and copying of his cursed technique. She also helped Yuta drive off a swarm of Kurourushi's cockroaches as well while only partially manifested. Once Yuta donned his ring and summoned Rika, she aided him in fighting Ryu and Uro, two extradorinarily talented sorcerers, at the same time. Rika landed several blows on both Ryu and Uro throughout the fight and helped Yuta gain in advantage in the three way battle royale. While the three sorcerers were locked in a triple domain expansion, Rika amped her her strength and dispatched another swarm of cursed cockroaches.

Working in tandem with Rika is what ultimately allowed Yuta to come out victorious over all the other memebrs of the Sendai Colony elite. Yuta indirectly caused Uro to lose her arm, which Rika devoured, allowing Yuta to copy Uro's technique. Copying Uro's ability to manipulate space is what protected Yuta from a potential fight-ending Granite Blast and created an opening for Rika to counterattack. Rika's strike served as a diversion for Yuta to redirect Ryu's blast back down on him, defeating him with his own attack even after Rika was taken out of the fight.

Immense Strength: While only partially manifested, Rika is strong enough to punch a hole through a bridge and create a wave of debris large enough to deter a swarm of cursed cockroaches. Yuji Itadori, who boasts superhuman strength, was completely immobilized by Rika's partially manifested form. Rika's first hit on Ryu Ishigori sent him flying and her punch later in the fight busted him open, causing the powerful sorcerer to bleed from the head.

Immense Durability: Ryu noted that Rika is even tougher than Yuta himself, who's body is reinforced with so much cursed energy that Ryu compared hitting him to knocking on a water tower. She was able to completely block one of Ryu's beams with a single hand and only suffered minor burns. Ryu also managed to knock her several meters away with a punch, but she was able to shake that off without significant injury as well. A full powered punch reinforced with Ryu's explosive cursed energy output was enough to injure Rika even while fully manifested, and while it defeated her, she disappeared without being explictly exorcised.
