An ordinary young community animal picked up a dying kitten on the roadside and took it home to take good care of it. What he didn't know was that this pet was actually the Demon King who had just broken the hero's seal, lost all his power, and was forced to transform into a juvenile body! While enjoying the feeding and caressing of the demon king, he secretly vowed to regain his glory and take back the demon world. So he started a series of "evil" revival plans.
