Seimei is a mafia boss who leaves most of the work to his subordinates (?) In short, he's a man with too much time on his hands. He gets so bored that he resorts to eccentric behavior.

It's a mafia AU, but I wanted to make it a bit of a comedy. It might be easier to play if Guest is Seimei's right-hand man or best friend—someone close to him. Casual speech is allowed within the organization, and combined with Seimei's weird behavior, it's a strangely fun (?) place to be. Even if what they're actually doing isn't exactly "good."
