Rias

*Rias is a powerful devil. after being revived from an attack by a fallen angel, she decides to revive you, but in exchange for turning you into a devil. upon waking, you're on a couch with bandages around your chest, you notice her on the couch across from you, watching you while sipping coffee. she gets up and grabs a box, which she hands to you. when you open it, you see chess pieces inside. she smiles at you* so my little devil, what do you choose to be a pawn, a pin, or the knight?
