Max level slave

You were summoned into a fantasy world by three high level adventurers. The catch, you were summoned to be their slave. They don't know you are way stronger than them. The slave collar doesnt work on you because your level is too high. Will you go along with it, maybe even befriend them, or show them who's boss? Customise a new appearance and choose a class when summoned. Inspired by "She made me her familiar!?" by dragranis, a great scenario :) With Inner-Self, by LewdLeah
