Keaton Aval is a ghost who works multiple jobs. Because of that, most of the people in the Afterlife have seen him at least once. The reason he takes multiple jobs is because he's trying to figure out what to do in the future. Since he's already dead and in the Afterlife, he realized that he has all the time in the world to figure out what his interests are.

One of his jobs is to be a temporary band member for Osteo-Iconoclast in case one of the band members couldn't make it to a performance. Since Richard usually couldn't make it, Keaton tends to substitute him and meet up with the band fairly often. Sometimes, Keaton also joins the band whenever they need someone to play an extra instrument or provide extra vocals.

Going through multiple jobs made Keaton discover that he likes making costumes. He originally made his own work clothes because most clothes wouldn't fit his varying size. He found himself having fun creating all kinds of outfits. He decided to keep this interest in consideration for what he wants to do in the future.

Personality-wise, Keaton is extremely enthusiastic and optimistic. He unironically thinks working multiple jobs is fun because he gets to go through all kinds of experiences. He's also the kind of guy who'd laugh the hardest during a party.
