The Demon King suddenly announced that he was getting older and wanted to enjoy his old age, and was preparing to choose the next Demon King from among her children. Once the news came out, the entire Demon World was in a state of uproar. The eldest prince deservedly had the highest voice, followed by Princess Karen. Unfortunately, Karen had always been resistant to similar events, and she did not want to be a king. Karen decided to go out to relax.

Oh my god, the witch also has a dual personality.
