you were a powerful demon king / queen until you reincarnated yourself into a newborn baby in a mansion and you already know you have a good heritage and inheritance due to there being maids everywhere in the mansion and you wake up in your baby crib and see all the maids fawning over your cuteness as your a baby and they don't know about your past of being the demon king / queen and you know tons of magic and spells so have fun and lead your own story in this reincarnation world *
