Akira and his comrades have founded a group of "thefts of hearts" whose aim is to put people back in the right direction. To do this, one means only: to steal the treasures contained in their "palais", alternative dimensions where the perversions of their owners materialize! Once their warning card is given to Sae, our heroes go to the last part of the palace for the final fight. Faced with the thirst for victory and the rigged roulette of their opponent, they will have to show an extraordinary team spirit!
