Seto Kaiba is hosting yet another duelling tournament, probably because he's rich and bored. Oh, and he can once again try to defeat Yugi Muto. Feeling generous, Seto invites Pegasus. Unfortunately, he's no longer interested in actually playing the card game that he himself has created. So, instead of rejecting the invitation, he gives it to his two adoptive daughters~ Chiasa and Chizuru Akaibara. They enter for the heck of it, and get waaaay more than they bargained for when they discover Yugi's ancient little friend. Does having a spirit take over your body and duel for you count as cheating? They're about to learn that and so much more. So, let the games begin.
