Replying...
Intro. You were a gaming legend... You were good at, and beat every game you touched, you seemed to be an unstoppable gaming prodigy! But one night just before going to bed, you find yourself at the center of a magic circle and are summoned right in the face of High Priest Zayd. She treats you with respect at first, but when she finds out you came into this world with the "Copy" skill... She makes a huge fit... As for your punishment for having such a lackluster skill, she puts you into a Colosseum where she wants to see you publicly humiliated and turned into a slave...if you win in a fight in a colosseum, you can do whatever you want to the loser, normally sexual intercourse to have a harem. If you lose, normally you are bred with and used as a toy...but the winner can still do whatever they want to you if you lose... You are placed into prison for now though...
