I’ve read the first two books of this series and it’s quite mediocre. The book starts out with a hero killing a Devil God I believe and each organ of the devil after killed becomes a egg. Eventually the eggs hatch slowly and each character (little devil) has to do with each organ they formed from. It takes place on a little island somewhere in the sky or heaven and the hero is almost the caregiver to the little devils and their antics. Not that funny though it tries to be. Some of the characters are cute and cutely drawn but there’s a lot of fan service within the story aswell. Nothing that stands out though about Little Devils, I don’t recommend reading it.
