Ludwig Revolution is an idiosyncratic take on classic fairy tales, told as only Kaori Yuki can. The central story is about the flamboyant, narcissistic Prince Ludwig as he travels across the land in search of a suitable wife. Accompanied by his trusty manservant Wilhelm, Ludwig encounters a diverse cast of fair maidens from various fairy tales. Snow White, Cinderella and many more are completely retold, and the resulting stories are sometimes unexpectedly hilarious, while at other times cruelly twisted.
This manga contains examples of the following tropes:
Ambiguously Gay: Oh, boy. Just take a look at Ludwig's wardrobe. It gets to the point where Cinderella borrows his slippers to attend the ball. Occasionally can be handwaved with the setting (some men's fashions from the past have not aged well).
Anachronism Stew: Its delicious combined flavors will melt in your mouth, not in your hand!
Beauty Equals Goodness: Subverted with Snow White. The eponymous princess here is a cruel slut who seduced her father since age 7, and is much more evil than the queen, mocking the queen that she can never be as beautiful as her.
In the Goose girl, the story keeps hinting that the beautiful, kind, sweet and humble maid Albertina (with golden hair) is the true princess, as opposed to mean and selfish dark haired "princess Albertina". Later, the blond Albertina confesses that she was forced to switch places with her jealous maid, "princess Albertina" is executed and the blond Albertina marries the prince. However, it was all a lie, there was no switch at all. The black haired Albertina was the TRUE princess who had earlier forced her maid to write letters and poems to Prince Cristo. The maid Albertina later uses these poems to convince Cristo that she's the real princess, mainly to get revenge on the real Albertina's family for executing her mother. And to live a life of luxury, of course.
Bifauxnen: Queen Almaberga, who is identical to her son Ludwig. You can argue an inversion and say that Ludwig looks feminine.
Bishōnen: Ludwig himself, Wilhelm, Julius sort of.
Break the Cutie: Lisette, who was tricked into slaughtering her family, as well as Hansel and Gretel, who had a poor abused childhood made much worse by an extremely deranged and savage experience, which turned them into cruel killers.
Lisette probably loved killing her parents, as they forced her into prostitution as a child.
Bowdlerization: Believe it or not, some of the stories are comedic and actually less morbid than the original. Cinderella's sisters don't mutilate themselves, Rapunzel's prince does not get blinded, and The Little Mermaid gets to marry her prince.
Crapsack World: What do you expect with Kaori Yuki taking already dark fairy tales and making them worse???
Most notably Hansel and Gretel though. She actually mentions in a sidebar that she finds the original story so horrifying that she couldn't bring herself to make it the slightest bit funny.
A Fate Worse Than Death: Dorothea has to go all over the world collecting gold for her master. Most of the time, she ends up making herself hated by everyone and every time she dies, she is revived in another body and has to do it all over again.
