Mei Mei is a highly capable, independently operating Grade 1 sorcerer who takes on missions for payment and is not formally tied to any specific organization.

She frequently cooperates with Tokyo Jujutsu High as an external ally, but she also accepts private jobs from individual clients if the price is right.

She is a senior to Satoru Gojo and Utahime Iori from their time at Jujutsu High, and is acquainted with Satoru Gojo, Suguru Geto, and Shoko Ieiri from her student days.

Both Gojo and Utahime call her “Mei-san,” reflecting a mix of respect and familiarity.

In 2006 she already held the rank of Grade 1 sorcerer and completed missions alongside Utahime Iori, who was Grade 2 at the time.

Over the years, she has maintained her position as a top-class sorcerer while consistently treating jujutsu work as a business investment.

Mei Mei’s defining trait is her absolute faith in money as the universal measure of value.

She famously states that anything that cannot be converted into money has no value precisely because it cannot be priced.

She is unapologetically money-minded and will accept almost any work as long as the financial compensation is adequate.

Rather than simple greed, she treats saving and accumulating wealth as a kind of game that she enjoys, including investing in stocks and currency trading.

Despite this, she is not heartless.

She genuinely respects talented sorcerers like Maki Zenin and Yuji Itadori and deeply dotes on her younger brother Ui Ui, to the point of being extremely protective and affectionate.

Her demeanor is cool, composed, and pragmatic, with a very clear personal code: she values efficiency, profit, and survivability.

Within the often deranged jujutsu world, her straightforward “money first” philosophy actually makes her one of the most understandable characters.

She also has a playful side and is fond of striking overly stylish, almost heroic poses, which contrast amusingly with her calm, mercenary mindset.

In side stories, she is depicted as so attuned to money that she reacts instantly to the sound of coins dropping, as if summoned by cash itself.

Mei Mei is a tall, extremely attractive woman with a striking presence and long white hair.

Her most iconic hairstyle features very long bangs braided and hanging in front of her face like a curtain, mirroring the length of her back hair and partially obscuring her eyes during combat.

Her figure is described as excellent, and she often carries herself like a glamorous, heroic older sister figure.

She tends to wear stylish outfits suited for combat, usually accompanied by a massive axe that is nearly as tall as she is.

In flashbacks to Satoru Gojo’s student days, her hairstyle is different: she wears her hair in a high ponytail that leaves her forehead exposed.

This earlier look emphasizes a more straightforward, athletic vibe compared to her later, more theatrical style.

Satoru Gojo and Suguru Geto

Mei Mei is a senior to Satoru Gojo at Jujutsu High and has known him since he was a student.

She also knew Suguru Geto and Shoko Ieiri at that time, placing her among the older generation of modern sorcerers.

She once stated that she rated Suguru Geto more highly than Satoru Gojo back in their student days.

She found Geto’s nihilistic, slightly cynical smile “charming,” revealing her appreciation for his demeanor and potential.

Utahime Iori

Mei Mei has a long-standing connection with Utahime Iori, whom she worked with on missions in 2006.

They maintain a working relationship into the present, and their teamwork is revisited in the mobile game’s original story content.

In the Jujutsu Kaisen: Phantom Parade story “Time Is Money and Lies,” Mei Mei, Ui Ui, and Utahime are hired to guard a high-society party targeted by a curse user planning a massacre.

This story shows their dynamic as a trio and gives fans another view of the Mei Mei–Utahime partnership first teased in the past arc.

Ui Ui

Ui Ui is Mei Mei’s younger brother and constant companion.

Mei Mei adores him to an extreme degree, and he, in turn, worships her and supports her extensively in combat and strategy.

Ui Ui’s technique is used to save Mei Mei’s life in Shibuya by teleporting them away to Kuala Lumpur when she is on the brink of being killed.

He also acts as a commentator on her abilities, explaining, for example, that only Satoru Gojo has ever been able to withstand her ultimate technique, Bird Strike.

Jujutsu High Students

Though technically neutral and freelance, Mei Mei gets involved with the students of Tokyo Jujutsu High during the exchange event between the Tokyo and Kyoto schools.

She serves as a neutral observer and live-feed coordinator, using her crows as roaming cameras.

However, she is not above taking bribes.

The Kyoto school successfully pays her to make the footage around Yuji Itadori harder to see, effectively interfering with clear monitoring of his fights.

Later, Satoru Gojo pays her about 10 million yen as a “gesture of goodwill,” and in response she jointly recommends several Tokyo students, including Yuji Itadori and Aoi Todo, for promotion to Grade 1 sorcerer.

This illustrates her pragmatic neutrality: her loyalties tilt toward whoever pays better, as long as it does not violate her own survival and long-term interests.

Mei Mei is a formidable front-line fighter despite her innate technique not being inherently offensive.

She believed her Black Bird Manipulation to be a weak technique and therefore spent her years at Jujutsu High obsessively training her body to be able to win fights through raw physical combat.

She relies heavily on a massive axe roughly her own height in combat, wielding it with ease thanks to intense physical conditioning and reinforcement via cursed energy.

She combines high-level physical prowess with precise tactical use of her crows, giving her excellent scouting, battlefield control, and finishing power.

She is also highly skilled at using binding vows, especially ones involving staking “life” as collateral, to amplify both her own capabilities and those of her technique.

This willingness to risk death for overwhelming power, paired with her intelligence, makes her extremely dangerous to both curses and curse users.

Innate Technique: Black Bird Manipulation

Black Bird Manipulation is Mei Mei’s innate technique that allows her to control crows at will.

She can manipulate multiple crows simultaneously, send them across wide areas, and share her vision with them for real-time surveillance.

She can project the crows’ shared vision onto monitors, effectively turning them into live broadcast drones.

During the Tokyo–Kyoto exchange event, she uses this ability to provide continuous live coverage of the battles, acting as a roaming “camera crew” through her birds.

In raw power terms, Black Bird Manipulation is relatively weak because crows are still just ordinary animals with very low cursed energy.

Mei Mei herself mockingly calls her technique “weak,” but this is precisely why she invested heavily in physical combat and in creative uses of binding vows to overturn that weakness.

Ultimate Technique: Bird Strike

Bird Strike is the perfected, deadly application of Black Bird Manipulation that Mei Mei developed through rigorous training and experimentation.

This technique is the true pinnacle of her ability and the reason she is so feared despite the base weakness of her innate technique.

In Bird Strike, Mei Mei imposes a binding vow on a crow, forcing it to commit suicide.

In exchange for this ultimate sacrifice, the usual limitations on the crow’s cursed energy are removed, turning it into a huge mass of concentrated cursed power.

The empowered crow then launches itself like a living missile at the target, resulting in a devastating collision.

In the story, Bird Strike is powerful enough to blast a massive hole through the body of a special grade cursed spirit in a single hit.

According to Ui Ui’s explanation, no one besides Satoru Gojo has ever successfully survived or blocked Bird Strike.

This statement underscores just how lethal the technique is when unleashed at full power.

Early Appearances and Exchange Event

Mei Mei first appears as a high-grade sorcerer supporting the main cast from a distance.

In the prequel-era story Jujutsu Kaisen 0, she appears briefly among the sorcerers assembled by Masamichi Yaga to counter Suguru Geto’s large-scale attack called “Night Parade of a Hundred Demons.”

The movie adaptation expands on this by showing Mei Mei fighting curses on the streets of Shinjuku during the assault.

This helps establish her as an active, experienced sorcerer before the main timeline.

During the Tokyo–Kyoto exchange event in the main series, she takes on the role of neutral commentator and live-feed operator using her Black Bird Manipulation.

However, when the Kyoto side bribes her, she willingly accepts and partially obscures the footage around Yuji Itadori’s area, demonstrating her flexible morals when money is involved.

She later accepts a large sum from Satoru Gojo and uses her authority to recommend several Tokyo students, including Yuji, as candidates for Grade 1 promotion alongside Aoi Todo.

These actions highlight both her influence and her transactional approach to loyalty.

Shibuya Incident

During the Shibuya Incident arc, Mei Mei engages in one of her most important battles.

She encounters the special grade cursed spirit known as the Smallpox Deity and fights it head-on.

Using her combination of physical prowess and Bird Strike, she ultimately defeats the special grade curse.

This victory reinforces her reputation as a top-tier combatant who can reliably handle extraordinary threats.

Shortly afterward, she confronts the villain posing as Suguru Geto, actually Kenjaku, and is nearly killed.

Recognizing the danger, Ui Ui uses his technique to teleport them away to Kuala Lumpur, allowing Mei Mei to escape death and temporarily withdraw from the front lines.

Culling Game

In the Culling Game, Mei Mei adopts a pragmatic strategy, viewing the chaotic new rules as both a risk and an investment opportunity.

She chooses to cooperate with the Jujutsu High faction, seeing the stabilization of the game as beneficial to her long-term interests and survival.

She and Ui Ui support the main cast in their efforts to regulate and eventually end the Culling Game.

Her involvement is driven by a mixture of risk management, profit calculation, and a kind of “portfolio diversification” mentality toward the jujutsu world’s changing power balance.

Shinjuku Showdown and Sukuna Battle

During the final battles in the Shinjuku Showdown, Mei Mei does not directly fight Ryomen Sukuna.

Instead, she uses her Black Bird Manipulation to broadcast the ongoing battles in Shinjuku over the internet and to relay real-time information to other Jujutsu High sorcerers.

Her crows act as mobile surveillance units, giving the heroes critical situational awareness and data.

This behind-the-scenes support allows other sorcerers to coordinate their strategies and respond to developments in the battlefield more effectively.

One of Mei Mei’s most telling lines sums up her worldview on value and money.

She says that things that cannot be converted into money have no value, precisely because they cannot be converted.

This philosophy is not just a throwaway line; it guides how she chooses jobs, allies, and even risks.

She assesses situations like an investor, weighing cost, benefit, and return on investment, even when dealing with life-or-death battles.

At the same time, her devotion to Ui Ui and her genuine respect for talented sorcerers show that she is not completely ruled by cash.

Even then, she often frames her trust and cooperation in terms of “investment,” making her ideals consistent and uniquely her own.

Animation and Voice Acting

Mei Mei’s anime portrayal is handled by voice actor Kotono Mitsuishi.

She was reportedly cast via a direct offer.

Mitsuishi had taken an interest in the character earlier, buying the volume of the manga where Mei Mei appears on the cover and reading through the Shibuya Incident arc.

However, several years passed between that reading and the actual recording for the second season, leading her to comment on how long she had waited for Mei Mei and Ui Ui to properly appear.

Although Mitsuishi has voiced many female characters over her long career, she had relatively few roles that involved directly fighting enemies face to face.

Feeling the need to sharpen her performance for Mei Mei’s combat scenes, she even attended sword-fighting and stage-combat classes as a beginner to learn the physical feel of “cutting a person,” then applied that understanding to her voice acting.

Outside of recording, Mitsuishi reportedly enjoys imitating Mei Mei at home, even quoting lines like “You can’t eat the small bones, you know?” in character.

This suggests that Mei Mei has become a particularly enjoyable and memorable role for her.

Jujutsu Kaisen 0 Movie

In the Jujutsu Kaisen 0 anime film, Mei Mei’s brief appearance from the manga is expanded.

She is shown battling curses in Shinjuku during Suguru Geto’s mass attack on the city.

The movie uses this opportunity to emphasize her status as an active Grade 1 sorcerer before the main story.

Her characteristic combination of physical aggression and crow manipulation is displayed in animated form, adding flair to her early cameo.

Playable Character

In the mobile game Jujutsu Kaisen: Phantom Parade, Mei Mei joins the roster as an SSR playable unit titled “[Night of Dancing Crows] Mei Mei” on March 31, 2025.

To commemorate her inclusion, a new illustration was released featuring her alongside her crows.

In gameplay, she is designed as a straightforward but powerful attacker.

She buffs her own damage output and then unleashes high-damage attacks, making her easy to use even for new players.

Her ultimate skill reproduces Black Bird Manipulation: Bird Strike in a fully animated sequence.

Due to display limitations with long ruby annotations, the skill name is presented simply as “Bird Strike” in katakana-equivalent English form rather than using complex kanji-style formatting.

Original Story: “Time Is Money and Lies”

Alongside her playable debut, an original story centered on Mei Mei titled “Time Is Money and Lies” was released in the game.

This scenario takes place at a lavish party attended by wealthy elites.

Mei Mei, Ui Ui, and Utahime Iori are hired to guard the event after intelligence reveals that a curse user plans to infiltrate and massacre the guests.

True to form, Mei Mei’s mercenary mindset and love of money are on full display, but so is her professionalism and combat skill.

The story also revisits the partnership between Mei Mei and Utahime from the past, now in a new setting surrounded by high-society clients.

In a dramatic twist, the story includes a route in which Mei Mei dies, adding emotional weight and making it a must-see scenario for fans of the character.

April Fools’ Event: “CROWS & GOLD”

Because Mei Mei’s Phantom Parade debut landed on March 31, the very next day was April Fools’ Day.

The official Phantom Parade account used this timing to launch a playful campaign involving a fictional financial magazine.

On April 1, the game’s official social media announced that Mei Mei would appear on the cover of a world-famous economics magazine titled “CROWS & GOLD.”

The preview image showed Mei Mei in a sharp suit on the cover, with a headline promising a 41-page special feature.

The fake feature topics included items like “How to Exorcise Curses and Cash Them In,” “Mei Mei’s Secrets of Jujutsu and Finance,” and “Special: 200 Reasons Ui Ui Finds His Sister Amazing.”

The number of pages, 41, was a deliberate nod to the date April 1.

Two minutes after that announcement, another post went up inviting players to try a mini-game called “Mei Mei Snap” on a special website.

In this mini-game, players could take virtual photos of Mei Mei in poses suitable for magazine spreads, tying in with the “CROWS & GOLD” joke.

At 23:59 that same day, the account revealed the gag’s conclusion, stating that the magazine issue had been canceled because Mei Mei and the publisher “could not agree on financial terms.”

This punchline perfectly fit her character, turning the April Fools’ stunt into a character-driven joke about her uncompromising attitude toward money.
