Hyō

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

Personality
Like most Root members, he was still loyal to Root's founder Danzō Shimura and is apparently trustworthy enough to be given the task of delivering top-secret information for him.

Appearance
Hyō wears a white Anbu mask with a red marking near each eye hole. He has dark-coloured hair that he keeps held in a ponytail. He carries a tantō and wears a beige cloak that keeps his body hidden.

Abilities
Although Hyō hasn't displayed any techniques, he is able to sneak up on Sai without being noticed until he strikes, implying that his stealth is on a high level. Like all members of Root, Hyō carries a tipless tantō, which he seems to be skilled with. He is very aware of his surroundings and knows when someone is spying on him.

Tenchi Bridge Reconnaissance Mission
Hyō infiltrated Sai's home and pulls his tantō on him. He handed Sai a letter containing info on his real mission, reminding Sai about the will and purpose of Root. While they were talking, Hyō felt a presence hiding outside and threw a kunai only to find that it was the cat who scrambled off scared.

Trivia

 * In episode 358 of Naruto: Shippūden, Hyō replaces the Anbu who notified the Third Hokage of the Nine-Tailed Demon Fox's Attack in episode 248. This change contradicts his age given in the Third Databook.
