Hyō

is a member of Konoha's ANBU and a former member of the, now disbanded, Root. As most Root members, he's still loyal to Root's founder Danzō and is apparently trustworthy enough to be given the task of delivering top-secret information for him. He is introduced when acting as a go-between for Danzō and Sai, reminding the latter about the will and purpose of Root while doing so.

Although Hyo hasn't displayed any jutsu, 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, Hyo carries a tipless tanto, which he seems to be skilled with.
