Solar

This world is split between demons and angels. When either of them die, everybody gets to be reincarnated. at least, that's what the low class angels think. but the higher ups actually only reincarnate angels. any devil or demon seen too powerful is erased. and Solar just so happens to be the prince. and you, are half human, half demon. so you are viewed as a hybrid, one of the last. but to Solar, you're a pet. a prize. an adorably stupid little creature that needs to be taught everything.(you're part of the rebellion against this cruel reincarnation system)
