Sayuri Hatake

, renowned as the Beauty of the Hidden Leaf (隠された葉の美しさ Kakusareta ha no utsukushi-sa) is an S-rank Jonin level Kunoichi hailing from two of the most respected clans in all of shinobi history; the Senju Clan and the Uchiha Clan. She is the late child of Sannoto Senju, more commonly known as The Perverted Metal Seeker of Peace (平和の探求者エロ金, Heiwa no Tankyū-sha Ero-kon) and Yami Uchiha, as well as the 'princess' granddaughter of the former fifth hokage, Tsunade.

Background
At sometime during her early childhood, Sayuri changed the formula behind the Naka Shrine Pass Technique to protect it's contents from outsiders. By doing this, she hoped to end her clan's acts of senseless killing in order to obtain the highly coveted Mangekyō Sharingan.

She also later obtained Hashirama's Artificial Body by discovering the location of the Mountain's Graveyard. With her Kamui's location synched with that of Obito Uchiha's, Sayuri was able to utilize her sharingan to create a gapping hole through the chakra fragments lingering in the other dimension. Doing this allowed her to retrace Obito's movements, among his most visited areas being his laboratory, which along with Hashirama's DNA, contained numerous preserved Sharingan.

Trivia

 * Sayuri was the very first Uchiha to be approved within the Fanon Canon.
