Anbu Commander

He is the ANBU commander from Konohagakure. Presumably he is the highest ranked member of the ANBU Black ops in the village.

Appearance
He is dressed in a white coat and black trousers with bandages tied around his right leg and black sandals. He also has brown hair and wears a mask with a dog motif inclusive of a single thick stipe along either sides of his cheek and his forehead.

Abilities
As the commander of the ANBU Black Ops he is presumably proficient in combat.

Invasion of Pain Arc
He is first seen in Tsunade's office when Naruto being called back is being debated. He is ordered by Tsunade to protect Shizune while she uncovers the secrets of Pain. Unfortunately this mission fails when Shizune is killed by the Human Path of Pain. After the battle of Konoha he informs Shikaku Nara of the emergency meeting which he attends along with Danzō, and the Konoha Council.

Trivia

 * He is initially shown with a standard black cloak in the anime. This was later corrected when he is shown at the Emergency meeting.
