Meh, typical Shoujo Novel's God/Guardian Spirit: "I screw up and destroyed the world, so I bring back the soul of the one with the most tragedy (not the actual character who screw things up, but the biggest collateral damage) then told them to fix everything. "
It's like Abandoned Empress all over again, although this one is slightly (only slightly) better by admitting that he "missed" the signs of destruction. I already know the people I want to punch in this story, so far there's 3 (the Spirit, the King, the Mistress).
