Utahime has long blackish-purple hair that extends down her back, with some strands tied behind her head, thin eyebrows, brown eyes and a scar on the right side of her face that crosses the bridge of her nose. She is slender and of average height.
Utahime wears a traditional miko outfit with a white colored top and a red colored bottom, along with brown colored boots.
On her day off, Utahime wears a dark purple baseball hat, white overalls over a black low cut long sleeved shirt, and dark colored shoes.
While Utahime was a student, she wore her hair in two pigtails and had no scar on her face, but still wore the same miko clothes.
Utahime is a relatively calm individual but is quick to anger when insulted. Such as when Gojo stated that she was unlikely to be the mole because she is weak Utahime threw her cup of tea at him.
Years ago, Utahime is conducting a mission along with Mei Mei when both of them get trapped within a spirit's barrier. As the two discuss what to do, Satoru Gojo arrives and frees them from the barrier. Utahime doesn't notice the curse that emerges from the rubble right behind her, but Suguru Geto appears and summons a spirit that devours the curse. Shoko Ieiri then shows up and asks if Utahime is alright, Utahime hugs her and responds saying she is happy to see her. After the mission is complete, Utahime and Mei Mei head back to the college.
Utahime arrives at Tokyo along with the Kyoto students and staff, to attend the Kyoto Sister-School Goodwill Event. As the Kyoto students start to insult one another, Utahime arrives and tells them to instead, fight with each other. Utahime then wonders where Gojo is. Gojo arrives and reveals that Sukuna's host, Yuji Itadori, is alive. Utahime then meets with Gojo, who tells her that there is a spy working with cursed spirits and that he wants her to investigate the Kyoto college for leads. When Utahime asks why he wants her to investigate since she could be the spy, Gojo replies that she doesn't have the nerve, which causes her to throw her cup of tea at him.
Utahime later meets up with the other staff members to watch the event, and just before it begins, Gojo has her make a speech to the students but doesn't give her enough time for one. While watching the event, Utahime wonders why their students can't get along, to what Gojo responds that they must take after her. When Kasumi Miwa is put to sleep by Toge Inumaki, Utahime becomes worried and decides to go get her. When all the talismans suddenly burn red, the spectators all believe that there is an intruder. Utahime along with Gojo and Yoshinobu Gakuganji decide to head over to the site and deal with the problem.
As the three head over to the site, they notice that a screen is covering the site. Utahime tells Gojo to head in before the site is fully covered. When Gojo says that the site is already covered, the three stop right in front of the screen. They decide to test out the screen and find that Gojo is the only one that can't enter, both Utahime and Yoshinobu head inside. Once inside, the two encounter Juzo Kumiya and Yoshinobu decides to take fight him alone while she goes to look for the students. As Utahime heads towards the students, she encounters Haruta Shigemo, another intruder. When Mai Zenin and Nobara Kugisaki show up to assist Utahime when the screen is lifted, causing the enemy to run away.
Once the intruders have been dealt with, Utahime attends a meeting with the other staff members about the events that ocurred. After the event is finished, Utahime heads back to Kyoto along with the students and staff.
Utahime meets up with Gojo, Nobara, Megumi Fushiguro and Yuji where she tells them that they suspect that Mechamaru is the mole. Utahime reveals that Mechamaru's real identity is Kokichi Muta, and explains how his puppet manipulation ability works. As they reach the room where Kokichi is supposed to be at, they find out that he is not there and come to the conclusion that Kokichi is the mole.
Utahime is on the train to Shibuya with the other Kyoto students, while they give Miwa privacy. When Mai asks what Kokichi did, Utahime replies that it no longer matters as he's already dead. She later arrives at Shibuya with the rest of her allies where they open fire on Pseudo-Geto. Pseudo-Geto uses Maximum: Uzumaki at point blank range on Miwa, Utahime along with Momo and Atsuya jumps in to protect her where Momo Nishimiya angrily yells at Utahime that she isn't supposed to be out on the front. When Choso suddenly arrives on the battlefield, and yells "Noritoshi Kamo", everyone is left in shock. Momo asks who that is and Utahime explains that Noritoshi Kamo was the blot of the Kamo family and also was the evilest sorcerer in history.
