The Evil Pieces (悪魔の駒(イーヴィル・ピース) Īviru Pīsu), also known as the Devil's Pieces, are a set of 15 chess pieces given to top-class Devils to increase their ranks by reincarnating other beings into Devils.

The Evil Pieces were created by[1]Ajuka Beelzebub to help replenish the number of Devils after the Great War which had caused the death of countless Devils. While many Devils were able to adapt to the Evil Pieces, only the Old Satan Faction of the Khaos Brigade resisted in the usage of the Evil Pieces, believing them to be a disgrace to Devils for reincarnating Humans and other races into Devils. The creation of the Evil Pieces eventually lead to the creation of the Rating Game.
