Kanoto

is a former member of Konohagakure's Anbu faction Root.

Background
To prevent Hiruzen from being reinstated as Hokage, Danzō gave Kanoto and nine other Root members a mission to assassinate him. Disguised as a foreign shinobi, he fought the Anbu accompanying his target, who turned out to be a disguised Kakashi, resulting in the mission's failure.

Appearance
Kanoto is a tall shinobi, with standing, medium-length brown hair. He wears a standard Anbu attire, and his mask has dark blue markings.

Abilities
As an Anbu, Kanoto is presumably a powerful shinobi. He wields a sword, indicating skills in kenjutsu. He could also coat his hands in chakra, augmenting the impact of his taijutsu-attacks.
