Tsubaki (椿, Tsubaki) is a kunoichi from Konohagakure. Tsubaki was the fiancée of Mizuki. She was well aware of him having met up with Orochimaru, and that he intended to steal the Scroll of Seals as a present to Orochimaru. However, Tsubaki understood the severity of the crime and the potential consequences Mizuki would reap upon himself, especially the intention behind it; she withheld this knowledge from the village, hoping that her fiancé would come to his senses. When Mizuki was defeated by Naruto Uzumaki and sentenced to Konoha Strict Correctional Facility, Tsubaki lamented that Mizuki had to be involved with Orochimaru.
