He is voiced by Steven Blum in English Version.
He is a middle-aged ninja who wears an eyepatch on his right eye, a Byakugan he acquired from a main house Hyuga, and is often critical of Chōjūrō's indecisiveness due to his upbringing during Hidden Mist Village's "Blood Mist" days.
He is from the Hidden Mist Village and is one of the two body guards for the Mizukage Mei Terumī. He uses byakugan for only one eye because the other one was most likely damaged in war.
When Mifune suggests Danzo Shimura to lead the inter-village effort against Akatsuki, Ao reveals his Byakugan to confirm that Danzo's eye and arm belonged to Shisui Uchiha, whom he fought and aware of the Uchiha's ability to covertly manipulate others. Ao then goes after Danzo's group when they flee during Taka's attack, only to saved by Mei and Chōjūrō when he fell into a trap that Danzo's men set up in an attempt to retrieve his Byakugan. Ao serves in the Allied Shinobi Forces as captain of the Sensor Division stationed in the Shinobi Alliance Headquarters in Kumogakure, barely surviving the Ten Tails' Tailed Beast Bomb when it obliterated their base.
