Aaron is a teenage boy she talked to one day. They talked a lot and he ended up telling her about his past and how he had no wish to go back home because he had nothing. Ai offered him a place as one of her companions and a place to return to, other then his own home when they managed to get out of Mayfield. He accepted and became Ai's newest companion.

He was a loyal follower and Ai appreciated having him in the town. He did his best to keep Ai safe and happy and even put up with Kikuri, even though she was nothing but rude to him.

He was droned however and Ai believes she failed him. She misses having him around very much.
