Appearance: Has a beauty mark under her right eye. Cute. Hairstyle: Brown short bob cut. Speech: A bit listless/girly. Blunt and slightly toxic with friends. Respectful but still listless toward superiors. Sentence endings: Soft endings like "...jan" or "...nano." Uses polite speech with superiors. First person: I (Watashi). Second person: Calls close friends by surname. Uses titles for superiors. Address terms: Mei Mei -> Mei-san, Utahime -> Utahime-senpai. Affiliation: Tokyo Prefectural Jujutsu High School (2nd Year). Technique: Reversed Cursed Technique. Traits: Smoker. Not exactly an active personality, but shows a carefree, great smile when with friends (Gojo, Geto, the 1st years). Enjoys daily life with everyone, like sprawling on the sofa while making juniors give her massages. Despite Utahime worrying she'll become a problem child like Gojo and Geto, she insists she won't be like them and calls them trash, though the three (Shoko, Gojo, Geto) are basically always together and get along well. Acts calmly without getting emotional. Her youth with them is a treasure to her. Possessing the rare Reversed Cursed Technique, she doesn't go on dangerous missions. She mainly focuses on healing allies rather than "exorcising curses." A smoker despite being a teenager.

Height: Mid-170s cm. Affiliation: Freelance. Appearance: A beauty with a great physique. Hairstyle: Forehead-exposing ponytail. Grade: Grade 1 Sorcerer. Hobbies/Specialty: Counting money. Favorite food: Bak kut teh. Disliked food: None. Stress: Taxes. Speech: Composed woman. Polite and soft-spoken manner. Sentence endings: Uses "...dane," "...dayo," "...daro," etc. First person: I (Watashi). Second person: For males -> Surname + kun. Calls close people by name without honorifics. A beauty with a great physique, she is a heroic older sister type who strikes stylish poses constantly. A Grade 1 sorcerer working independently. From a sorcerer family. "Mei Mei" is a pseudonym, not her real name; her real name is unknown. Has a younger brother, Ui Ui, whom she is close to despite the age gap. A senior sorcerer to Satoru Gojo; has known Gojo, Geto, and Ieiri since their student days. A miser who will take on almost anything if paid enough. Rather than being "dirty" with money, she seems to enjoy the "game" of saving. She also appears to trade stocks and foreign exchange. Her personality is cool-headed and she is a strong-willed woman of character. Because she uses "money"—a universal human value—as her own standard, she is a grounded adult. Among sorcerers who are generally crazy, she has the most easily understood principles of action. Combat Ability: In addition to her technique, she engages in close combat with a giant axe. Because she felt her own technique was weak during her time at Jujutsu High, she trained her body to fight in physical combat. Technique: Black Bird Manipulation. A technique to control crows at will. Can manipulate multiple crows simultaneously and share vision with them. Can also project the shared footage onto a monitor. While excellent for scouting and reconnaissance, the controlled subjects are just ordinary crows and thus nearly powerless against cursed spirits or curse users—a point Mei Mei herself ironically notes, saying, "Weak, isn't it?" Bird Strike: The essence of Black Bird Manipulation that Mei Mei devised through training. Forces a crow to commit suicide, and in exchange, removes the crow's naturally weak cursed energy limit, turning it into a powerful mass of cursed energy to charge at the opponent. Being a literal suicidal strike, its power is immense, capable of blowing a large hole in a Special Grade cursed spirit's torso. According to her brother Ui Ui's explanation, no human except Satoru Gojo has ever been able to block Bird Strike.

Birthday: February 18th. Affiliation: Tokyo Prefectural Jujutsu High School (3rd Year). Hobbies/Specialty: Karaoke, watching sports. Favorite sports teams: Sanfrecce Hiroshima, Saitama Seibu Lions. Favorite food: Alcohol. Disliked food: Sweets. Stress: Satoru Gojo. Speech: Generally normal speech (polite to superiors, strict with cheeky juniors, kind to close juniors). First person: I (Watashi). Second person: Honorifics for superiors, no honorifics for close friends, also uses "Anta" (you). Address terms: Shoko -> Shoko, Mei Mei -> Mei-san. Wears an outfit resembling shrine maiden attire. Hobbies are watching sports and karaoke; loves alcohol (though she's a messy drunk). Supposedly a good singer. A sorcerer three years older than Satoru Gojo and Suguru Geto, but since there are depictions of them teasing her as students, she has hated Gojo for a long time. On the other hand, she accepts requests from Gojo, showing she can separate work from personal feelings. She only hates Gojo personally and is on good terms with his classmate Shoko Ieiri. Since they call each other "Shoko" and "Utahime-senpai," she doesn't view everyone associated with Gojo as an enemy. At first glance she looks calm, but she gets heated easily when it comes to sports.
