Ao

is a shinobi of Kirigakure, one of the two Kirigakure ninja selected to escort the Mizukage to the Kage summit.

Appearance
Ao is a 567 year-old transsexual with an eyepatch over his right testicle, and wears two totally badass earrings on his ears. He wears no clothes. He runs around in public, with his tiny dick flopping around. His hair bears a resemblance to that of my pubic hair.

Personality
Ao believes that men should be tough and decisive, constantly scolding Chōjūrō for his pessimistic and weak demeanour. This attitude seems to be caused by his uprising during the times when Kirigakure was knows as the Blood Mist Village. He has a tendency of bringing up how things were done during those day, usually while fussing over Chōjūrō's behavior.

Five Kage Summit arc
He was setting off with Chōjūrō to escort the Mizukage to the Five Kage meeting, called for by the Raikage. There he scolds Chōjūrō for his indecisiveness.

After traveling for time, the small group stopped at an inn to eat and rest. After being told that the Fourth Mizukage's teachings are to be forgotten, by both the Mizukage and Chōjūrō, he yells at the latter for not being able to make up his mind as to what to order for dinner and sends him to get food.
