Legend tells of terrible monsters that inhabit the chaos emeralds. If one of true power summons the creature using a certain ritual, the creature will be his or hers to command. And Mephiles plans to do just that. But when the creature is summoned, it is quite different from what he was expecting. Collab w/ ShadowWeasel Rated T for blood.

Riku had a terrible darkness inside of him. A darkness that made him kill and steal hearts. He never forgot his first kill either...a poor helpless girl...but that was years ago. Now Riku has made sure he can't be found. He won't make those mistakes again. But a new girl might change everything... AU, One-Shot, this isn't what I usually write just wanted to mix it up.
