Uraume (裏梅うらうめ Uraume?), also known as The Frozen Star (凍いて星ぼし Iteboshi?), is a recurring antagonist in the Jujutsu Kaisen series. They are a curse user from a thousand years ago who is a subordinate to Sukuna. They aligned themselves with Kenjaku to seal Satoru Gojo and revive their master.Uraume appears as a slim, white haired monk with chin-length white hair, an irregular line of dark plum pink running horizontally across the back of their head, and dark pink eyes with long eyelashes. They wear a plain monk robe of dark blue, which is white on the innermost layer. Their appearance is androgynous, and they usually wear a blank expression outside of battle.Uraume is usually seen with a stoic and calm expression, their main trait being their loyalty to Sukuna, to the point where Sukuna was actually excited to see Uraume upon meeting them a thousand years later in Shibuya.[3]

Uraume is shown to be ruthless when Kenjaku tells them to leave the sorcerers alive, but they say only Yuji is needed as a messenger. Uraume also has a short temper, as they tell Choso to get out of the way because they won't wait much longer, they also got visibly annoyed with Yuji when he saved Choso, asking him whose body do you think that is?

Uraume has also expressed annoyance towards Kenjaku at multiple points, often telling him to leave their presence and commenting on him talking too much. Uraume can become exceedingly hostile if someone should show any form of disrespect toward Sukuna, which can also lead to them acting recklessly, such as when they tried to attack Satoru Gojo for insulting Sukuna.

Like most curse users, Uraume has little respect for a sorcerer's sense of humanity, seeing it as a weakness. They complimented Hakari for not having this trait in their battle. Uraume's aforementioned loyalty to Sukuna precedes their value of their own life, as after sensing Sukuna had perished, they chose to bisect their own neck before telling Hakari that his allies were merely lucky Sukuna was bound to an incarnated form.[4]
