- Complete Monster: From the anime:
- Count La Trémoille, the Grand Chamberlain of France and Counselor of Princess Charlotte de Valois, and Montmorency's cousin, tries to conspire with England by having "peace talks" with them in order to make France surrender so that he could be seen as its savior. In his spare time, he is a sinister collector of several stuffed fairies and plans to add Montmorency's Fairy Companion, Astaroth, to his collection. Seeing Montmorency using a little girl named Jeanne as a savior to liberate France as a hindrance to his plans, La Trémoille tries to sabotage all of Montmorency's plans, with his methods including having him thrown into the dungeon and then instigating the Inquisition so that they could perform a virginity test towards Jeanne, which would result in her getting gang-raped. In addition, he also instigates the villagers so that Jeanne would perform the test. Finally, he tries to sabotage Montmorency's plans to liberate Orleans by starting a war with him.
- Final 3 episodes: Enlil himself is the king of the 72 gods, a race of aliens who created humankind. Seeing humans as flawed beings, Enlil decided to annihilate his creations in order to create a peaceful utopia ruled by him, where his inhabitants will have no free will of their own. Defeated by Astaroth centuries ago and stored inside the void dimension, Enlil escapes by possessing Montmorency, where he decimates multiple humans and calls upon his spaceships to destroy earth. When Montmorency tries to fight back, Enlil forces him to watch Jeanne burn at the stake.
- So Bad, It's Good: The prevailing opinion of those watching the show. It's not good by any real means, but the sheer amount of jank in the premise alone, combined with the titillating gender-bending and complete ignorance of history makes the show a joy to laugh about.
- Woolseyism: While the dub can't quite make it seem diegetic, the edit in the first episode that keeps the teacher from being precognizant of the Hundred Years' War's name is very much an improvement.
