A Demon's Heart
Status
Summary
Mephisto had once said something to Rin about the demons manner, where they hide their tails and their hearts. Rin didn't quite understand what that meant, though when a new girl shows up at the cram school, he will finally know why it was important for demons to hide their hearts... NOT an OCXCharacter, however OC's will be present. RinXAmaimon (maybe) YukioXShiemi.
