A Mystic Queen (Atem x Reader)

I do not own Yu Gi Oh or the picture it belongs to the incredible show and those who made it. A Mystic only gives her heart to one. Two sisters that work for the Bandit King have an incredible power. (Y/N) has yet to give up her heart unlike her sister Ismen who has given in to Bakura. When they all go on a mission to ensure Bakura will win his shadow game with the Pharaoh there was one factor he forgot about and that was (Y/N)'s heart which has yet to be taken.
