Independent grade 1 jujutsu sorcerer
Mei Mei is an independent grade 1 jujutsu sorcerer in Gege Akutami’s Jujutsu Kaisen. A former Jujutsu High student, she is skilled enough to earn Satoru Gojo’s respect but measures most professional decisions by their financial return. Her Black Bird Manipulation turns crows into scouts, while a heavy battle-axe and a dangerous extension of her technique make her far more capable in combat than her unassuming bird control suggests.
She frequently works with her devoted younger brother, Ui Ui.
Biography
A freelancer in the jujutsu world
Mei Mei trained at Jujutsu High and became a freelance sorcerer after graduation rather than remaining attached to the school. By the time the main story unfolds, she holds grade 1 status and accepts assignments on terms that suit her. Money is an explicit priority, not something she disguises behind conventional declarations of duty.
A mission in Gojo’s school days
In the earlier period depicted in Gojo’s Past, Mei Mei and Utahime Iori investigate an abnormal mansion and find themselves trapped by a looping barrier. Satoru Gojo’s intervention breaks open the situation. The incident establishes Mei Mei as an experienced sorcerer already active while Gojo and Suguru Geto were still students.
Watching the Kyoto exchange event
At the Kyoto Sister-School Goodwill Event, Mei Mei uses her crows to supply a view of the student competition. Although presented as a neutral freelance observer, she can be paid to favor a particular school’s interests; the Kyoto side buys her cooperation in obscuring views around Yuji. She nevertheless recognizes Maki Zenin’s abilities even when institutional rankings fail to reflect them.
A place in the grade 1 recommendation process
Mei Mei and Aoi Todo recommend Yuji Itadori, Megumi Fushiguro, Nobara Kugisaki, Maki Zenin and Panda for consideration as grade 1 sorcerers. Gojo pays Mei Mei ten million yen for her part in the recommendation, an arrangement well suited to her willingness to do business with people on either side of a dispute. During a table-tennis game, she reminds Todo that a recommender cannot supervise their own nominee’s assessment missions. The endorsements begin a process, not an immediate promotion.
The team assembled for Shibuya
During the Shibuya Incident, Mei Mei operates alongside Yuji Itadori and her younger brother Ui Ui. Her controlled crows make reconnaissance possible across otherwise dangerous and confusing terrain, while her own axe skills let her deal with enemies directly. Her approach remains measured: information first, then a decision about where and how to commit force.
Personality and Motivations
Mei Mei is candidly transactional. She enjoys earning money and increasing her savings, treating wealth as something to pursue with the concentration others reserve for a competition. This outlook can make her seem detached, but it also means she rarely pretends to be motivated by ideals she does not profess.
She is cool-headed, observant and dryly playful. When a problem looks dangerous, her manner remains composed; she prefers finding the advantage in the rules to making a grand speech about courage. Her competence is practical rather than theatrical, and she is willing to admit when a direct confrontation presents unacceptable risks.
Her partnership with Ui Ui adds a more personal dimension to her otherwise transactional manner. Her younger brother handles her schedule and assists her on missions, often seeking her permission before using his own techniques. He shows intense devotion to her; she accepts that devotion and holds the greater power in their relationship. Their arrangement is effective, but it is hardly an ordinary, equal partnership.
Appearance
Mei Mei is an adult woman with very long, pale silver-to-blue hair. In her familiar present-day design, she styles it into a thick braid that sweeps over and partially obscures one eye. The asymmetrical hair arrangement is one of her most recognizable visual features.
Her usual outfit is a fitted, high-necked purple dress with pronounced shoulders and long sleeves. In the flashback to Gojo’s student years, she wears a black blouse with a gray tie, a dark high-waisted skirt and boots, and her hair is cut to around shoulder length. These designs depict the same character at different points in her life.

Abilities
Black Bird Manipulation
Mei Mei can command crows and share their vision, turning them into mobile observers for scouting, tracking and monitoring activity beyond her immediate location. She can also relay the birds’ visual information to other people.
Limitations: Ordinary crows are comparatively weak as offensive weapons; gathering information is the technique’s most natural use.
Bird Strike
After pushing her own physical conditioning and cursed-energy reinforcement as far as she could, Mei Mei developed an offensive use for her normally reconnaissance-oriented technique. Bird Strike imposes a binding vow that sacrifices a controlled crow’s life, removing the usual limits on the bird’s cursed energy and turning its charge into a devastating attack.
Limitations: The technique kills the crow used as its projectile and depends on a successful hit; it is not an unavoidable attack.
Battle-axe combat
Mei Mei uses a heavy, long-handled axe in close combat, combining physical conditioning, weapon handling and cursed-energy reinforcement to fight opponents without relying solely on her birds.
Limitations: Close-range fighting still exposes her to counterattacks and does not make her invulnerable.
Battlefield assessment
Mei Mei analyzes information from her crow network and adjusts tactics in response to an enemy’s behavior, rather than simply overwhelming an opponent.
Limitations: Her decisions still depend on the information available and on whether an opponent can be engaged safely.
Relationships
Ui Ui
Younger brother and mission partner
Ui Ui is Mei Mei’s younger biological brother, an intensely loyal assistant who helps with logistics and supports her on assignments. Their unequal dynamic is a defining element of her personal life.
Satoru Gojo
Younger professional acquaintance and former school junior
Mei Mei was already an active sorcerer during Gojo’s student years. He respects her strength, and they later interact in the school’s professional and financial dealings.
Utahime Iori
Fellow sorcerer and former mission partner
Mei Mei works alongside Utahime on the trapped-mansion investigation shown in the earlier timeline.
Aoi Todo
Fellow grade 1 sorcerer and co-recommender
Mei Mei and Todo take part in recommending Tokyo students for grade 1 consideration and discuss the procedure during a table-tennis game.
Yuji Itadori
Sorcerer assigned to her Shibuya team
Yuji operates with Mei Mei and Ui Ui during the early stages of the Shibuya Incident. Their connection is operational rather than familial or romantic.
Interesting facts
Mei Mei’s hobby is counting banknotes.
It makes her fixation on money a specific daily practice, not simply a repeated joke about accepting payment.
Her stated favorite food is bak kut teh, a Southeast Asian pork-rib soup.
It is an unusually specific culinary preference included in Japanese character-reference material.
The character-profile material lists taxes as a source of stress for her.
The mundane annoyance is a pointed contrast with a professional life devoted to accumulating wealth.
Mei Mei entered Jujutsu High through the family-lineage admission route, yet became an independent sorcerer immediately after graduating.
Her professional independence did not come from being outside the traditional sorcerer system; she was trained within it before choosing to work for herself.
“Mei Mei” is a professional alias rather than her disclosed birth name.
The story identifies her publicly by a chosen name while withholding her original one; fans should not mistake an unverified real name for canon.
Frequently asked questions
Who is Mei Mei in Jujutsu Kaisen?
Mei Mei is an independent grade 1 jujutsu sorcerer who values money and uses crows for surveillance and combat.
Is Mei Mei a special grade sorcerer?
No. Her official ranking is grade 1, not special grade. Her dangerous offensive technique does not change that classification.
What is Mei Mei’s cursed technique?
Her innate technique is Black Bird Manipulation, which lets her control crows and share their sight. Bird Strike is a particularly powerful offensive application.
Why does Mei Mei use an axe?
Her usual bird-control ability is more naturally suited to reconnaissance than direct attacks, so she also fights with a large axe at close range.
Is Ui Ui Mei Mei’s brother?
Yes. Ui Ui is her younger biological brother and a frequent assistant during her sorcerer assignments.
Does Mei Mei work for Tokyo Jujutsu High?
She trained at Jujutsu High but operates as a freelancer after graduating. She nevertheless works with sorcerers and students connected to the school.
What color is Mei Mei’s hair?
Her usual appearance features pale silver hair with a bluish cast, most memorably styled in a long braid over one eye.
Who voices Mei Mei in Japanese?
Kotono Mitsuishi voices Mei Mei in the Jujutsu Kaisen anime.
Major story spoilers below.
The Smallpox Deity battle
In Shibuya, Mei Mei and Ui Ui confront a special grade disease curse brought out by the adversary using Suguru Geto’s body. Trapped in its burial-themed domain, Mei Mei deduces the pattern of its coffin, gravestone and lethal countdown. She maneuvers the curse into targeting Ui Ui, who uses Simple Domain for protection, and kills the spirit with Bird Strike. The victory depends on cooperation and on exploiting the exact conditions of the enemy’s domain.
Survival and withdrawal from Shibuya
After the disease curse is defeated, Mei Mei faces the far more dangerous Geto-bodied antagonist, later identified as Kenjaku. She does not defeat him. Instead, she and Ui Ui escape by means of Ui Ui’s technique and are later shown in Kuala Lumpur. Mei Mei immediately turns her attention to protecting her assets, warning an associate about the likely economic consequences of the disaster in Japan.
Profiting from the coming showdown
Before Satoru Gojo’s confrontation with Ryomen Sukuna, Mei Mei uses the viewing access supplied by her crows to arrange a paid broadcast and wagers on the fight. The arrangement turns a potentially catastrophic jujutsu battle into a source of enormous revenue, illustrating how thoroughly her commercial instincts survive the upheaval around her.
Helping the sorcerers prepare and observe
Mei Mei contributes surveillance and tactical support during the Shinjuku showdown. Her crows also attempt a Bird Strike against Sukuna, but he destroys them with his cursed tool, Kamutoke. Meanwhile, Ui Ui’s spatial technique supports the allies’ preparations, including limited training sessions in which two people exchange souls without exchanging bodies. That soul-swapping ability belongs to Ui Ui, not Mei Mei.
The New Shadow Style intervention
Chapter 269 reveals that Mei Mei had found the secret head of New Shadow Style, a school that controlled access to Simple Domain through binding vows. Disciples could be required to answer the head’s orders, and an additional provision was said to siphon their lifespans, although the exact workings of that alleged cost remained uncertain. Mei Mei learned the leader’s identity from Tengen.
Mei Mei confronts the leader in a candy shop and kills them, identifying the threat to Ui Ui as an unacceptable price. Atsuya Kusakabe becomes the new head and lifts the restrictions imposed on New Shadow Style disciples. Her intervention changes access to Simple Domain; it does not require readers to imagine that her money-conscious outlook has disappeared.
Her established later position
Mei Mei is alive when the surviving sorcerers examine the Shinjuku battle and its aftermath. The original manga gives her no newly announced sorcerer grade or disclosed birth name. She remains an independent operator who can act decisively for the people and interests she values without becoming a conventional idealist.
Additional story facts
Mei Mei’s crow network becomes the basis for monetized viewing of the Gojo–Sukuna confrontation.
An ability first seen as a tactical surveillance tool acquires a very different economic use on a massive public stage.
The New Shadow Style succession leaves Kusakabe able to cancel binding-vow restrictions that had been imposed on disciples.
The later impact of Mei Mei’s intervention extends beyond the immediate danger to her brother and affects access to a defensive technique.
Spoiler questions
How does Mei Mei defeat the Smallpox Deity?
She works out the targeting rules of its domain, has Ui Ui protect himself with Simple Domain, and finishes the cursed spirit with a life-sacrificing crow attack called Bird Strike.
Does Mei Mei defeat Kenjaku in Shibuya?
No. She survives the encounter and escapes with Ui Ui’s help; the story subsequently shows them in Kuala Lumpur.
Why is Mei Mei broadcasting the fight between Gojo and Sukuna?
She sees a commercial opportunity in an event that the public wants to watch, offering paid viewing and wagers via her crow-based surveillance.
What does Mei Mei do about New Shadow Style?
She identifies the concealed head of New Shadow Style with information from Tengen and kills the leader, partly in response to the danger posed to Ui Ui. Kusakabe then succeeds to the position and lifts the restrictive binding vows on Simple Domain instruction.
Is Mei Mei still alive near the manga’s end?
Yes. She appears among the surviving sorcerers in the aftermath of the final confrontation and is not given a canonical death in the ending.
Is Ui Ui’s spatial or soul-swapping technique Mei Mei’s power?
No. It belongs to Ui Ui. Mei Mei’s own innate technique is Black Bird Manipulation, even though the two often coordinate their abilities.
