Kim Isaac, once the all-powerful Skeleton King, is now a baby in a onesie. Tricked by the gods and sealed away, he’s reincarnated into a family of saints at the heart of the Holy Empire. He can’t walk or talk, but he can plot. And with his loyal demon followers working from the shadows and a grudge deeper than the underworld itself, this baby isn’t here to be cute—he’s here for payback. The Holy Empire has no idea what's coming… and the gods are about to regret ever crossing the Skeleton King.
