Why 3 characters in one role ?, because these are background characters that I'll probably use again in the future, 2 are devils and one isn't but still got horns, they are regular clients and often hangout with Haze, in terms of personnality, it's totally up to you to bring it to the table, If you wanna do more improvised lines or if you got an idea for the character go ahead. Accent, manners, whatever can bring them to life. If you are the right pick we can work on this characters design together.
