Ui Ui ( (うい) (うい) Ui Ui?) is a supporting character in the Jujutsu Kaisen series. He is a sorcerer and the younger brother of Mei Mei.

Appearance

Ui Ui is a young boy with a small slender frame, light blue hair that is styled with a neat right-sided part and mint-green eyes with thin eyebrows.

Ui Ui wears a long-sleeved jacket similar to the Jujutsu High uniform. He also sports suspenders, shorts, long socks, and simple shoes.

Personality

Ui Ui is a mature and proper young man who really doesn't display any typical traits for someone his age. He's defined by his loyalty and devotion to his sister. He worships Mei Mei and is more than happy to do all of her biddings, even willing to die for her. Ui Ui expresses great disdain toward any individuals who inconvenience or disrespect Mei Mei in any way. He wasn't very friendly with Yuji Itadori while they were on the same team in Shibuya simply because he was too close to Mei Mei, though later got on better terms a month after. Ui Ui is horrified whenever Mei Mei gets in danger but this quickly changes to excitement when she turns things around.

Ui Ui appears to get along with nearly all of the Jujutsu High sorcerers and even helped out Maki Zenin with some personal business[1] but will still get annoyed if they (namely Yuji) do not understand his abilities. Ui Ui is also quite brave, not showing much particular fear of Sukuna while rescuing his injured comrades after they are wounded by the King of Curses.

Abilities and Powers

Overall Skill: Ui Ui is still too young to be a professional jujutsu sorcerer. However, he's still capable of handling dangerous situations and being a useful asset in battle. Mei Mei trusted him on her team during the Shibuya Incident with Yuji. He carried her axe outside of combat and was responsible for countering domains, making him useful to his grade 1 sister rather than a liability.[2] Regardless of his age, Ui Ui possesses a talent for jujutsu, proven by his ability to use his innate technique as well as barrier techniques.

Cursed Restrictions

Binding Vows
Ui Ui has a binding vow with his sister Mei Mei where he agrees to limit his cursed energy and restrict his usage of jujutsu until she gives him permission. This stems from his own desire to please his elder sister.[3][4]

Cursed Technique

Innate Technique

Spatial Transference: Ui Ui's technique is the spatial transference of "targets" that allows him to teleport himself and others with him to locations and people he has marked. By concealing himself and others with a sheet, Ui Ui can teleport himself and others to another location.[5] This technique allows him to spatially transfer himself or others across vast distances within a short time, as seen when Mei Mei and him escaped from Kenjaku by teleporting from Shibuya, Japan to Kuala Lumpur, Malaysia in less than two hours.[6] His technique also allowed him to act as a liaison along with Maki Zenin during the Culling Game, and allowed the jujutsu sorcerers to recover the bodies of Satoru Gojo and Hiromi Higuruma during the Shinjuku Showdown.[5]
If Ui Ui's target is a person, the technique targets their body and soul altogether. If given permission, he can target only the soul, which allows him to switch the souls of his marked targets without changing the shapes of their bodies.[7] This application of Ui Ui's technique can only be used twice per person in a month.[8] (Unnamed)

Anti-Domain Techniques

New Shadow Style: Simple Domain (シン・ (かげ) (りゅう) (かん) () (りょう) (いき) Shin Kageryu: Kan'i Ryōiki?): An anti-domain technique that neutralizes a domain's barrier and disables its sure-hit effect in a set area of space around the user. Ui Ui used Simple Domain to counter the Smallpox Deity's domain, avoiding its gravestone after getting trapped inside a coffin.[9]
