In a bold move that no one could have predicted, Satan possesses the body of a stillborn Rin and does his very best to raise Yukio. He's actually quite good at it, demonic tendencies and hyper-possessiveness aside.

In this universe the True Cross requires every demon or nephilim in the Order to become a familiar to join, and even the Demon Kings are not an exception to this.
