Power Progression

Stage / Realm / Level	Chapter	Notes
Grade 2	4 11	Reached through intensive physical training. Already capable of killing Grade 2 cursed spirits with a single axe swing, but further advancement required developing Black Bird Manipulation.
Grade 1	22	Promoted the day before her announcement after developing her technique’s ultimate attack during Tsukasa’s fifteen-day absence. His aerial weapon barrage inspired the breakthrough; she describes the resulting strike as capable of killing a special-grade cursed spirit.

Background / History

Mei Mei entered Jujutsu High through her family background. During her first year, Yuki Tsukumo looked after her for a time; Mei Mei keeps a photograph of them together in her dormitory 21 28.

Initially dissatisfied with Black Bird Manipulation’s reconnaissance-focused applications, she devoted herself to hand-to-hand combat. This made her a standout Tokyo student and helped Tokyo defeat Kyoto in the Sister Team Battle. Her physical training eventually plateaued, forcing her to reconsider the offensive potential of her innate technique 4 22.

Appearance

Mei Mei has a slender figure, fair skin, and long white or silver hair, usually tied in a neat ponytail. Her movements and voice are repeatedly described as elegant and mature 4 12 20.

• Eyes: Violet-gray irises are specifically described at her graduation 27.
• Mission attire: Knee-high boots and a rectangular case carried on her back 10 12.
• Dormitory attire: A pale-purple T-shirt and black shorts, with her hair worn loose 20.
• Shopping outfit: A Patrick Star T-shirt, loose trousers, and canvas shoes, deliberately coordinated with Tsukasa’s clothes 32.
• Personal details: Purple-painted toenails and a light, refined fragrance 12 15.

Personality

Mei Mei openly treats sorcery as paid work rather than an altruistic calling. She enjoys saving and counting money, exploits profitable opportunities, and uses praise or feigned vulnerability to negotiate larger rewards. Her betting pool demonstrates calculated opportunism: after discovering Tsukasa’s Special Grade identification, she accepts wagers only on Gojo’s victory 5 11 22.

Her confidence rests on hard-earned skill, but Tsukasa’s overwhelming talent sometimes leaves her envious and discouraged. Despite this insecurity, she remains cautious on unfamiliar missions and becomes willing to challenge stronger opponents once she develops her ultimate crow attack 15 22 24.

Around Tsukasa, her teasing increasingly conceals genuine affection. She is moved by his remembering her favorite meal, frightened by his apparent death, and pleased by their prolonged handholding. Her concern becomes explicitly protective when she mistakenly concludes that he comes from a poor, single-parent household 21 24 32 35.

Abilities & Skills

Black Bird Manipulation

Mei Mei controls black crows and shares their vision, using them to gather information and inspect dangerous locations 11 22.

• Remote reconnaissance: Sends a crow into a deep well to investigate a hidden curse 11.
• Personal surveillance: Checks Tsukasa’s outfit through her technique before choosing matching clothes for their shopping trip 32.
• Limitations: A scouting crow can be killed; the well’s curse eats her bird before the pair enter 11.
• Early assessment: She initially considers the technique useful mainly for intelligence and shared vision, with little direct combat value 22.

Black Bird Manipulation: Divine Wind

Divine Wind turns a crow into a sacrificial projectile. The bird abandons its cursed-energy limits and crashes into the target at the cost of its life 25.

• Lethality: Mei Mei describes her newly developed ultimate move as capable of killing a special-grade cursed spirit in one strike 22.
• Confirmed application: Destroys the weakened Heart God after Tsukasa throws it toward a circling crow 25.
• Cost: The attacking crow dies; the technique depends on its sacrifice 25.
• Combat impact: Gives Mei Mei the confidence to fight above her own grade alongside Tsukasa 24.

Close-Quarters Combat and Axe Fighting

Years of physical training make Mei Mei an accomplished close-range fighter, even before her technique’s offensive breakthrough 4 11 22.

• Kills Grade 2 cursed spirits with individual axe swings 4.
• Infuses her axe with cursed energy to cleave through multiple heart-shaped curses 24.
• Uses a kick to spring away from the Heart God and return to Tsukasa’s side 24.
• Embeds her axe in the Heart God’s chest, then spins to launch it into the air for Tsukasa’s follow-up 24.
• Physical training alone reaches a ceiling and does not secure her Grade 1 promotion 22.

Coordinated Mission Tactics

Mei Mei and Tsukasa develop familiar attack patterns and communicate through brief looks and gestures. After her breakthrough, their missions increasingly rely on coordinated attacks rather than Tsukasa fighting alone 24 25.

Plan	Roles	Mei Mei’s Code Phrase
A	Tsukasa handles the enemy while Mei Mei stays behind him.	“What am I to you?” 25
B	Tsukasa provides support; Mei Mei delivers the finishing attack.	“Would you die for your senior?” 25
C	Both retreat if they cannot win.	“It’s getting chilly, and night is coming. Your senior needs to go home and save money. Hurry, hurry, hurry...” 25

Vulnerabilities

• Desire manipulation: A shrine curse’s Simple Domain exploits her love of money, making her pursue illusory banknotes toward a cliff. Tsukasa must restrain and knock her unconscious to save her 15 16.
• Detection limits: At the Kanagawa well, she cannot sense the curse fifty meters below and relies on crow reconnaissance 11.

Equipment / Weapons / Items

• Cursed Axe — A long axe used for exorcisms and cursed-energy-enhanced attacks 15 24.
• Rectangular carrying case — Carries her axe during missions; Tsukasa willingly shoulders it during their first assignment together 10 11 15.
• Red flip phone — Used for messages, payment notifications, and checking her balance 12.
• Blue jade pendant — A deep-blue, diamond-shaped Hatayama family heirloom with a silver chain. Tsukasa gives it to her at graduation as a token of affection; she claims she will safeguard it until he turns eighteen 27.

Relationships

• Tsukasa Hatayama — Junior, longtime mission partner, and developing romantic interest. His sincere respect contrasts with her initially financial motives; their partnership grows into mutual trust, affectionate teasing, and a shopping date 11 21 31 32.
• Yuki Tsukumo — Former first-year mentor. Mei Mei calls her willful and mischievously sends her a recording of Tsukasa saying Mei Mei is prettier 21.
• Utahime Iori — Fellow sorcerer who visits Tokyo hoping for Mei Mei’s help with her weak technique. They later disappear together during a Grade 1 assignment 13 34.
• Masamichi Yaga — Teacher who recognizes her strength and entrusts her with returning Tsukasa’s forgotten wallet and student ID 4 8.
• Satoru Gojo — Junior who addresses her respectfully as “Miss Mei,” but resents her closeness with Tsukasa. His confidence also supplies the opportunity for her profitable betting pool 5 27 34.
