Eihei Uzumaki

Background
Born two unknown parents in Konoha, she lived a normal civilian life, until she was snapped up by the ANBU for her potential in espionage and information gathering missions. She was later sent to the ANBU's Root offshoot, and was taught in the use of the tanto and some kenjutsu. In large part, her childhood was stolen from her, as Danzo had her trained to lose all her emotions, and as part of that kept her isolated from all other people outside of Root members. When Root was disbanded after Danzo's, she took to traveling as she didn't have much else to do with herself. She also took to improving her kenjutsu skills with her tanto.

Personality
Being a former member of Root and a survivor of Danzo's grueling training sessions, she is highly emotionless, never really reacting to Toshin's and Raionhato's antics, and quickly enlisting to become a member of Hilt so that she wouldn't have any "distractions". Despite this, she does have a level of arrogance, believing herself to be far superior to other shinobi and kuniochi because she was a member of Root. Like other current and former Root shinobi, she displayed extraordinary levelheadedness while in the heat of battle.
