- Complete Monster: King Darius was once a simple soldier banished by the king, who would abuse the witch Dorethea until she tricked him into going into the well of Blue Flames. Discovering the power of the Well, he spitefully murders the entire kingdom and revives them as zombies eternally condemned to create and find gold for him. A monster on both a large and small scale, for his personal revenge Darius turns the king into a mindless demon as a mocking form of "mercy" and forces Dorethea to die and be reborn over and over again to find gold for him. Upon Prince Ludwig and his allies coming to save his friend Dorethea, Darius orders their deaths right in front of Dorethea out of sheer amusement.
- Foe Yay: Very much canon with Julius's interest in Ludwig.
- Hollywood Homely: What Katrein actually is. Sure, she's no gorgeous beauty, but she isn't downright ugly. And hasn't hit puberty yet, either.
- Ho Yay: Subtext between Ludwig and Wilhelm. This is a Kaori Yuki manga, after all.
- Moe: Cinderella!!! Also, according to the Otaku prince, blonde Albertina. Oh, how wrong he is... There's also Katrein, in a young, haughy kind of way.
- Real Women Don't Wear Dresses: Not in Kaori Yuki's world. Lisette always wears a dress, Amalberga wears both a military outfit with a skirt and a royal dress, both are psychopaths, but unfeminine? Never!
YMMV / Ludwig Revolution
