Momo is a short girl with a very youthful appearance. She has blonde hair tied into two pig-tails tied at the base and ends that point upwards and pale blue eyes. Both her ears are pierced with two earrings and she also sports a collar on her neck. She's always with her signature broom, befitting her witch-like appearance.
Momo's school uniform consists of a loose, short-sleeved black dress that ends mid-calf and black ballerina shoes.
Momo first appears as a reserved girl who is intimidated by the students from the Tokyo School. She has a close relationship with the other girls at her school, Kasumi and Mai, and believes that women are unfairly treated in the jujutsu world, in comparison to men. This prejudice influences her own personality, as Momo is shown to care a lot about "cuteness" and her overall appearance.
Additionally, Momo is quick to follow the belief that Yuji is a danger to everyone, causing her to form a rivalry with Nobara Kugisaki. However, despite her rocky relationship with some of the students, she is a team player and will do her best to help in a crisis.
Momo arrives at the Tokyo college along with the other students and faculty, for the Kyoto Goodwill Event. After encountering the Tokyo students and staff, Momo attends the pre-event meeting. During the meeting, Momo talks with the other students about their plan to kill Sukuna's host, Yuji.
Once the event starts, Momo rides on her broom, attempting to locate Yuji. When she finds him, she contacts the others about Yuji's location and how Aoi is currently facing him. After the Kyoto students decide to let Aoi handle Yuji, Momo goes to look for the cursed spirits scattered in the forest, but is suddenly attacked by one of Megumi's shikigami, Nue. Momo lands in a tree and notices that Megumi's Nue ability is affecting her, then Panda and Nobara show up and greet her.
Momo and Nobara talk about how principal Yoshinobu wants the Kyoto students to kill Yuji. Momo then gets upset about how Nobara insults Mai and decides to teach her a lesson. She fights Nobara by keeping out of Nobara's reach and attacking from a distance. Momo also manages to use her broom to land a blow on Nobara's face, which angers Nobara. Momo then explains that women sorcerers are expected to be flawless, both physically and skill-wise, unlike men who don't face these prejudices. Her speech causes Nobara to get angrier.
Momo continues to be cautious and makes sure to keep her distance from Nobara, because of what Noritoshi told her about Toge's cursed speech ability. She manages to dodge Nobara's attack, and explains what it means to be a sorcerer of the Zenin clan. Nobara pins her nails to the trees, which proceed to fall on Momo, but Momo evades them. When Nobara manages to get close, Momo kicks her away and distances herself. Nobara obtains a straw from Momo's broom and uses her technique on it, which causes Momo to lose control of her broom. Afterwards, Momo is attacked multiple times by Nobara with a squeaky hammer. Just as Nobara is about to knock Momo unconscious, Mai shoots Nobara forcing her to fall down. Momo is then contacted by Mai, who tells her to continue helping their team from the sky.
Later, Momo notices that a screen is starting to cover the site where the Kyoto Goodwill Event is happening at. Momo then helps bring Toge and Noritoshi outside of the screen. When the invasion is over, Momo agrees to continue the Kyoto Goodwill Event along with the others. She attends a game of baseball with the other students and is even allowed to use her cursed power. When Aoi is hit by the ball while at bat, Momo along with the other Kyoto students compliment Maki for hitting him. After the event is over, Momo along with the other students and faculty head back to Kyoto.
Kokichi Muta manipulated the events to ensure that none of his classmates would be put in harms way during the Shibuya Incident. As a result of that, Momo and the other Kyoto students and facility member, Utahime, are on the train to Shibuya while they give Miwa privacy to mourn Kokichi. Momo comments on how Kokichi kept going on about how both them and Todo won't die. She then agrees with Utahime saying that it doesn't matter anymore. Momo then says whoever makes her younger classmates cry will die.
At 11:36pm, Momo arrives with her allies and signals for her allies to open fire on Pseudo-Geto. When Miwa's attack fails and Geto unleashes Maximum: Uzumaki at point blank range on Miwa, Momo notices and goes to protect her. Upon noticing Utahime next to her, Momo immediately yells at her that she isn't supposed to be out on the front lines. When Choso suddenly arrives and confronts Pseudo-Geto about being his father, this leaves Momo confused as to what Choso meant. Utahime then explains to Momo that Noritoshi Kamo was the blot of the Kamo family, known as the evilest sorcerer in history.
Momo is up in the air when Uraume uses Frost Calm to freeze the opposing enemies, leaving her free to move. She uses her Wind Scythe attack and directs it at Geto and Uraume, who are able to block it with ease, shocking her. Momo tells Yuji that they're the only ones able to move and should buy time so that Utahime can get ready. Momo attempts to attack but Uraume uses Ice Fall and tries to crush them all until the timely arrival of Yuki Tsukumo who saves them all from death. She realizes there's no backup from Mai and says there might still be more of them but Yuki assures her that her comrades are protecting Aoi and Mai.
Momo who had ran up to the Zenin household finds Maki walking down with Mai's body over her shoulder. She starts tearing up as Maki gives her Mai's body, telling her Mai is in her hands now. While cradling Mai's body, Momo asks Maki what she's going to do who doesn't answer.
