Second-year Kyoto Jujutsu High student and New Shadow Style swordswoman
Kasumi Miwa is a supporting character in Gege Akutami’s Jujutsu Kaisen and a second-year student at Kyoto Jujutsu High. An unusually straightforward and considerate presence among her outspoken classmates, she trains with a katana and New Shadow Style rather than relying on an innate cursed technique. Her desire to improve as a sorcerer is also practical: she wants to earn enough to ease her family’s financial difficulties.
Miwa’s earnest self-doubt, careful sword discipline, and open admiration for Satoru Gojo give her a distinctly human perspective on a dangerous profession.
Biography
A student with practical reasons to fight
Miwa grows up in a financially struggling family with two younger brothers and takes part-time work while still in junior high school. A New Shadow Style instructor approaches her during one of those shifts, despite her having no experience with a katana or even a practice sword. She has the ability to see curses, but no innate cursed technique; sword training offers her a way into jujutsu sorcery. For Miwa, rising through the sorcerer grades is not about fame: she hopes that better pay will make life easier for her family.
In Kyoto’s second-year class, Miwa stands out less for flamboyant confidence than for being polite, sensible, and unusually candid. She is a dedicated student even when comparing herself unfavorably with stronger peers, and she still makes room for ordinary teenage enthusiasm.
The Kyoto–Tokyo Goodwill Event
During the sister-school competition, Miwa fights for the Kyoto team and demonstrates New Shadow Style sword techniques. Her matchup with Tokyo student Maki Zenin exposes the limitations of her approach against someone with exceptional speed and close-combat skill: Maki closes the gap and disarms her. The defeat is revealing rather than a proof that Miwa lacks discipline; she follows a practiced method but must contend with opponents able to disrupt it.
Miwa’s more lighthearted side also surfaces around the competition. She admires Satoru Gojo with the unguarded excitement of a fan, an amusing contrast with how other sorcerers react to him. Her tendency to take people at their word, even when they tease her, fits the same open and trusting temperament.
Training beside Kyoto classmates
Miwa serves alongside classmates such as Mai Zenin, Momo Nishimiya, and the remote-controlled figure known as Ultimate Mechamaru. Her interactions with them make clear that she is neither a hardened cynic nor a purely comic bystander. She cares about her peers, even when she is unsure how much use she can be in the high-stakes conflicts surrounding them.
Personality and Motivations
Miwa is candid, polite, and relatively down-to-earth. Kyoto Jujutsu High contains several forceful personalities, so her ordinary sense of courtesy is especially noticeable. She is willing to admit when she is scared, impressed, or outmatched rather than constantly posing as invincible.
She can be self-deprecating about her effectiveness, but her training and willingness to confront difficult situations show that this insecurity is not the same as indifference. Her financial motivation is rooted in family responsibility, while her delight at seeing Gojo shows a lighter side that her stern uniform does not advertise.
Appearance
Miwa is recognizable by her long, straight, pale blue hair and blunt-cut bangs, with blue-toned eyes in her anime character design. She ordinarily wears a dark, tailored Kyoto Jujutsu High uniform styled like a suit, with a white shirt and dark tie. Her katana and sheath complete her characteristic silhouette.

Abilities
New Shadow Style swordsmanship
Miwa uses New Shadow Style swordsmanship and cursed energy rather than a personal innate cursed technique. Her signature Battō (Sword Drawing) attack accelerates the sheathed, cursed-energy-coated blade for a rapid strike against a target in front of her.
Limitations: The draw depends on timing, positioning, and keeping control of her weapon. An opponent with superior speed or a way to disrupt the stance can counter it, as Maki Zenin demonstrates.
Simple Domain
Miwa can deploy New Shadow Style: Simple Domain, a small defensive zone around her. In her sword-based version, a target entering the zone triggers an automatic countering slash. Simple Domain can also oppose the guaranteed-hit effect of a full Domain Expansion.
Limitations: Her usual sword-based setup depends on a fixed stance; moving both feet from their starting positions dispels that configuration. Simple Domain is a defensive countermeasure, not an innate Domain Expansion.
Relationships
Satoru Gojo
Admired senior sorcerer
Miwa is an unabashed admirer of the Tokyo teacher and is visibly excited by the chance to see and photograph him. The admiration is a fan’s enthusiasm, not an established personal relationship.
Maki Zenin
Rival-school opponent
Maki, a Tokyo student, defeats and disarms Miwa during the Goodwill Event. Their match is a lesson in the gap between polished technique and exceptional physical combat ability.
Mai Zenin
Kyoto classmate
Mai is a classmate who sometimes teases the straightforward Miwa. They belong to the same Kyoto school cohort and participate in the interschool event.
Kokichi Muta (Ultimate Mechamaru)
Kyoto classmate
Miwa knows Kokichi primarily through his remotely operated Mechamaru form and treats him as one of her fellow students. Their later story involves important revelations kept in the spoiler section.
Utahime Iori
Kyoto teacher
Utahime teaches at Miwa’s school and helps manage the often-disparate personalities of its students.
Momo Nishimiya
Kyoto upperclassmate
Momo is an older Kyoto student who participates alongside Miwa and her classmates in school activities and later conflicts.
Interesting facts
In a Jujutsu Kaisen fanbook Q&A, Gege Akutami explained that he wanted an ordinary, starstruck character. Miwa’s surname plays on the Japanese term “mihaa,” while her given name came from a former classmate’s name that he liked.
Both the name and the design idea fit the contrast between Miwa’s everyday enthusiasm and the more eccentric sorcerers around her.
Character-profile material lists saving money as one of Miwa’s notable skills or interests.
It is an unusually everyday specialty for a combat-oriented cast and reinforces the concrete financial pressures behind her choices.
Miwa’s food preferences are listed as hotpot and a dislike of cilantro.
These low-stakes preferences give the reserved-looking swordswoman ordinary tastes outside combat and school rivalries.
After classmates told Miwa that Mechamaru liked AA batteries, she gave him a single battery for Valentine’s Day instead of the usual courtesy chocolate.
The joke depends on Miwa believing a playful claim about a puppet that actually runs on cursed energy—not batteries.

Major story spoilers below.
The message Kokichi left behind
During the Shibuya Incident, Miwa travels toward Tokyo with other Kyoto students despite Kokichi Muta’s attempt to keep them away: he had arranged for them to be assigned missions elsewhere. On the train, a miniature Mechamaru device delivers Kokichi’s final message. Miwa asks whether he kept her away because he regarded her as useless; he answers by acknowledging his own weakness and mistakes. He speaks of someone he loved and wished to protect, then asks Miwa to find happiness. She breaks down in tears as the device falls silent. His affection is unmistakable, but the manga does not establish that the two had become a couple.
The sword stroke that costs her future attacks
Later in Shibuya, Miwa joins the Kyoto team’s attempt to confront the sorcerer occupying Suguru Geto’s body, later identified as Kenjaku. She puts everything she has into a New Shadow Style sword-drawing attack, effectively staking her future ability to swing a katana on the strike. Kenjaku stops it and breaks the sword. Atsuya Kusakabe intervenes to shield her when a far more dangerous attack follows. The lasting consequence of Miwa’s vow is confirmed during later battle planning: she can no longer use a katana for ordinary combat.
A brief appearance during the Culling Game
Miwa is shown walking through the Sendai Colony during the Culling Game. The story does not substantiate theories that her sombre expression signals a secret transformation or a new innate technique; those suggestions are speculation, not a confirmed change to her identity or powers.
Protecting Maki without drawing a sword
When Sukuna unleashes Malevolent Shrine during the Shinjuku battle, Miwa contributes through Simple Domain, shielding Maki Zenin from the domain’s cutting effect. This defensive role matters precisely because Miwa’s earlier vow has taken away her signature offensive weapon. She does not suddenly regain unrestricted sword use or acquire an unexplained new innate technique.
After the fight, Miwa is present among the surviving sorcerers and admits how frightened she was while protecting Maki. The later discussion also reveals that the New Shadow Style school placed onerous binding-vow restrictions on its disciples. Kusakabe, now its head, announces that he has removed those institutional restrictions. The narrative does not state that this change cancels Miwa’s separate, self-imposed vow never to swing a katana. Her subsequent career and personal future are not given a detailed definitive epilogue.
Additional story facts
During the post-battle discussion, Miwa worries that Todo’s swapping technique might have rescued only her while she was serving as a marker for Maki.
Her fear centers on the danger to the person she was protecting, adding a specific dimension to her otherwise understated defensive contribution.
When Kusakabe announces that he has become head of New Shadow Style, Miwa reacts with open astonishment—and reacts again when Mei Mei jokes about charging membership fees.
Her unguarded reactions make an otherwise technical discussion of institutional binding vows unexpectedly personal and recognizably Miwa-like.
Spoiler questions
What happens between Miwa and Mechamaru in Shibuya?
Kokichi leaves her a final message through a Mechamaru device. He admits his feelings and his desire for her happiness, then says goodbye; Miwa cries. The manga does not explicitly confirm that they had already become a couple.
Why can Kasumi Miwa no longer use a katana?
She stakes her future sword use on one desperate attack against Kenjaku in Shibuya. The strike fails, but the binding vow still prevents her from wielding a katana afterward.
Does Miwa help Maki against Sukuna?
Yes. She uses Simple Domain to protect Maki from the slashing effect of Sukuna’s Malevolent Shrine during the Shinjuku battle.
Does Kasumi Miwa die in Jujutsu Kaisen?
No. She is shown alive with the other sorcerers during the post-battle discussion in Chapter 269. The original manga does not provide an extensive individual epilogue for her.
Does Miwa gain a new innate technique in the Culling Game?
No new innate technique is established for her. Her quiet appearance in Sendai Colony inspired speculation, but the manga does not confirm those theories.
Do the final New Shadow Style reforms restore Miwa’s katana attacks?
The reforms remove the school’s imposed restrictions on disciples. They are not shown to undo the separate vow Miwa made during her failed strike at Kenjaku, so that restoration cannot be treated as canon.
