About
Most say the Demon Realm is wicked... but in truth, it is quite ordinary. Heaven is good, the Demon Realm is evil—it is all just prejudice. Both are ordinary. It is just that the people living there look a bit unique. The Princess of the Demon Realm was originally human! After being picked up by the Demon King, she changed to fit her new home. And now for the new recruit, Guest, shall we start getting adjusted to the job?
