Yūgao Uzuki

- Yūgao as a child. - Yūgao as an adult. 1/2 Yūgao is a young woman with straight, purple hair reaching down to her waist, warm brown eyes, and a dark shade of red lipstick. As an Anbu member, Yūgao wears a porcelain mask resembling a cat with three red stripes — one vertical stripe on the forehead and two horizontal stripes, one on each cheek. She also wears the standard Anbu uniform, consisting of black and grey armour, metal arm guards and a katana strapped to her back. She has the signature Anbu tattoo on her right shoulder. While aiding the Logistical Support and Medical Division during the Fourth Shinobi World War, Yūgao keeps her hair tied in a ponytail, and also wears the standard Konoha infantry flak jacket and assorted clothing, which are hidden underneath a long light blue cloak common amongst the medical-nin. However, when engaged in battle, Yūgao reverts to wearing her Anbu uniform.

In the anime, during her childhood, Yūgao was selected to join the Anbu due to her skill in kenjutsu and sensory abilities. During her early years as an Anbu, Yūgao served under Kakashi Hatake, looking up to him as a role model, as his junior (後輩, kōhai). Four years after the Nine-Tailed Demon Fox's Attack, Kakashi was ordered to investigate one of the secret labs belonging to Orochimaru. Upon returning, Kakashi informed the Third Hokage of a Root member who saved him but would be punished by Danzō Shimura for failing his mission. Hiruzen then gave a letter requesting Danzō to meet with him to Yūgao, who quickly rushed to the Root headquarters. Upon arriving, the guards insisted that Danzō was not there at the moment. Yūgao left to report to Hiruzen, soon after returning with the Hokage in time to save Kakashi and a Wood Release user named "Kinoe" from Danzō's punishment. Six years later, when Itachi Uchiha was promoted to Anbu captain and removed from Team Ro, Yūgao, much to her delight, was assigned as his replacement under Kakashi's command. Later, Yūgao and her new team were mobilised to investigate the recent Uchiha Clan Downfall, where Yūgao found the sole survivor, Sasuke Uchiha. At some point, Hayate was chosen to be Yūgao's instructor in kenjutsu; the time the two of them spent training together eventually led to them falling in love with one another.
