It has six eyes, and also fiery red eyes.

Rika

Rika Kimoto is a cursed spirit with a vengeful heart. She is an extremely powerful character with a huge reserve of cursed energy.

Rika's power includes replenishing Yuta Etotsu's curse energy reserves, storing weapons, and fighting alongside Yuta Etotsu when fully manifested.

Although Rika is very powerful, it has been confirmed that she is not as strong as Sukuna, who is the "King of Curses." However, considering Sukuna's current weakened state and the help of other characters, it is possible for Rika to defeat Sukuna in the upcoming battle.

Rika was once a vengeful spirit, created after the death of Yuta Otokoku's childhood friend, Rika Inori.

Rika died in a tragic car accident, and at that time, Yuta Otsuko's words unknowingly turned her into a vengeful cursed spirit.

Rika continued to torment Etoki Yuu for many years, making his life miserable in many ways, until he entered Jujutsu High School, where he began to train himself to become stronger and better master Rika's powers in order to help her.

As a vengeful spirit, Rika is very difficult for Yuta Otsukoshi to control, simply because at this stage of the story, Yuta Otsukoshi himself is not sure of his feelings for her.

He didn't realize that it was his mistake that turned Rika into a vengeful spirit.

In the original work, Yuta Otsukoshi and Rika eventually accepted each other. Yuta Otsukoshi conveyed his feelings for her and accepted her true self.

He conveyed his love, which helped Rika's soul finally find peace.

Rika is no longer a vengeful spirit. However, interestingly, the power that allowed Rika to exist as a spirit still remains in Yuta Otokoku.

This was simply because Yuta's childhood friend, Rika Kimoto, wanted to leave something behind to protect Yuta and safeguard him forever.

Thus, the cursed spirit Rika was eventually born.

Of all the cursed spirits, it's safe to say that Rika is the strongest so far.

In fact, Rika is so powerful that Natsume himself named her the Cursed Queen.

This was before Rika reached her current power level, at which time her power was likely even greater than in Jujutsu Kaisen 0, as evidenced by her absolutely enormous size and larger energy pool. Rika's most unusual trait is that she possesses a massive pool of cursed energy.

Rika's energy is immeasurable. In fact, she can replenish Ottokoyata's own cursed energy reserves multiple times effortlessly, demonstrating her formidable power. However, if that's not enough, Rika can provide further assistance in battle through weapon storage. Ottokoyata can often store anything within Rika, making her a true asset to him in combat. Furthermore, Rika can fight on her own. When Ottokoyata fully manifests her using his ring, Rika appears and fights in his place.

There's no doubt that her power is enough to defeat almost anyone in battle. Most recently, during the elimination rounds, when Yuuta Otsuki fought a three-way battle against Kyōko Utsugi and Ryū Ishiryū. With her astonishing reserves of cursed energy, weapon stockpile, and of course, the powerful beam of love, Rika was virtually unstoppable in battle, a cursed spirit worthy of being called the Cursed Queen.
