Everyone atleast once in there life has wished to see or be a mythical or godly creature but not Kusuo Saiki, he hates what he is. You see in this world people's souls aren't born from nothing, there born from a mythical or godly creature, and bad enough for Saiki he has the rarest of them all, the god soul. That alone is what makes him hate his life but it also makes it so a variety of souls are drawn to him and the one soul that can't resist a gods is the second rarest, the Angel and that so happens to be the perfect pretty girl Teruhashi.
