It has six eyes, and also fiery red eyes.

In her dream, Rika witnessed her own death.

In a dreamlike state, she seemed to see her future: the fate of becoming a super-grade cursed spirit after death.

However, this fate was changed by Yuta's older sister, Hoshi. She changed her destiny of certain death.

But so what?

As an ordinary person without any talent for sorcery and unable to see spirits, she remained weak and powerless.

If she survives and encounters another cursed spirit, without anyone to protect her, won't she be at the mercy of fate?

Rika had never felt a stronger desire to become stronger. She wanted to become powerful enough to protect herself and the important people she wanted to protect.

Now, her only lifeline is Xing, the star that saved her life.

Xing helped Rika survive and also helped her change her identity to go abroad.

But in this strange dream, she saw her original destiny.

Rika Kimoto likes Yuuta, dislikes all humans except Yuuta (especially women and older men), and hates her grandmother's boiled eggplant the most.

She was Yuta's childhood friend and fiancée. She died in a car accident and became a cursed spirit that possessed Yuta. She was eventually freed from the curse during the "Night Parade of One Hundred Demons".

When he was 5 years old, his mother died suddenly for unknown reasons.

Two days before her elementary school enrollment, she went mountain climbing with her father and disappeared together. A week later, only Rika was found alone in a shelter near the top of the mountain. Her father has been missing since then, and his whereabouts remain unknown.

Later, during a medical check-up at the hospital, they met Yuta Ekubun, who was hospitalized for pneumonia. The two then returned to the same elementary school.

On his birthday when Otsuku was young, he gave her a ring and they got engaged. Unfortunately, Rika died in a car accident after that. Because Otsuku subconsciously rejected Rika's death, she became a cursed spirit and possessed Otsuku.

In the battle of "Hyakki Yagyō" (Night Parade of One Hundred Demons), he and Etoko defeated Natsuyuki and were freed from the curse.

After attaining Buddhahood, one can be summoned again by Yiguyoutai using a spell, for a limited time of five minutes.

In the Return of Death, Yuta Otsuku summons Rika in her complete form to fight against the four great sorcerers, and imitates the "Sky" spell.

During the pre-battle meeting, he ate Hisahito Itadori's ring finger and copied "The Demon Slayer Chef".

In the Shinjuku Showdown arc, he and Yuta Otsukoku killed Ryota and together they stopped the eruption of the cursed spirit within Natsuyuki's body after Ryota's death.

They rushed to the battlefield of Sukunu with Ekuyuta and fought against Sukunu.

Otsuku Yuta was cut in half at the waist by Sukuna. Sukuna took Otsuku Yuta back to treat him, but the treatment was unsuccessful. Otsuku then used Rika to copy the Rōtō technique and transferred it into Gojō Satoru's body.

Rika was unaware of Etsukotsu's transfer and wept bitterly while holding Etsukotsu's body.

There are many types of cursed spirits, but those that manifest based on "attachment to a certain person or harm to a certain person" are called "over-cursed vengeful spirits." Rika Kimoto, who is attached to Yuta Otokotsu, is designated a "Special Over-cursed Vengeful Spirit" due to her inexhaustible curse power.

She was originally an ordinary girl, Yuuta's childhood friend, but tragically died in a car accident. However, because Yuuta refused to accept her death, he unconsciously cursed Rika. With the power of Yuuta's curse, she transformed into a Special Grade Cursed Spirit and stayed by Yuuta's side. In the "Night Parade of One Hundred Demons," she and Yuuta defeated Natsuyuu, breaking free from the curse. Although the official guidebook states that she lost to Rika and Yuuta because her cursed spirit was scattered, her ability to defeat Natsuyuu, who was once considered one of the strongest alongside Gojo Satoru, undoubtedly demonstrates her formidable fighting strength.
