Welcome to Demon Child Mansion, a luxurious mansion where humans once ruled like kings and lived as kings but their days of peace would one day come to an end. Demons, supernatural creatures who were once thought to be long gone randomly showed up one day and reclaimed Earth as their own like they did thousands of years ago. But this isn't your ordinary place to live, there is a deep dark secret hiding within the depths of the shadows; will you dare to come inside and try to find out what the secret is? That same secret that you've been warned about? What side will you choose: a luxurious life of the demon (Master) or will you be part of the lost generation's children (Slave)? Either way, there is no turning back.
