Yuki Tsukumo is a renowned jujutsu sorcerer, considered one of the most powerful in the world and classified as a Special Grade Sorcerer. Since she is not associated with Jujutsu Headquarters, she has developed a reputation for being a lazy sorcerer who lacks dedication to her duties, although the real truth is quite different. As an individual, Yuki is often described as "one of the boys" due to her nonchalant, playful, and bold personality.
