The Baby Demon King Finds the Hero Dads Way Too Annoying

She was reincarnated as a four-year-old little demon king in a slave market. The demon king is even a puppet being used by other demons because she is too weak! But did the warriors misunderstand the demon who was tormenting me as a demon king and punished him? Oh, wait a minute. I'm young and weak, and there's a long way to live in the demon world anyway... "Can't I hide the fact that I'm the Demon King somehow and make the warriors my guardians?" (Source: Kakao Entertainment Corp., translated)
