Prologue

A child named Ayumu Kenji lives a peaceful life with Mephisto Pheles and Amaimon, the Earth King. But what happens when Ayumu wanders from home and into the city?
Bad behavior doesn't go well with Mephisto, and it certainly doesn't go well with Rin when Ayumu is passed onto him.
Could this child be more special than he appears when put into Rin's hands? Or will everything go wrong?
