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