Knight Protects Her Highness Princess Hatsune

This world is different. What stories would people from two parallel worlds have to say? Man: No, that's not the case. Why, why, why is God so hard on me! Evil: This world is inherently evil, and only by becoming a demon can all this be resolved. Good: People are divided into good and evil. Maybe I am born evil, but I can use my good nature to protect everything here.
