- Awesome Music: Every single music piece is great, but especially "Jounetsu" (the Flamenco song), "The Angel that can't fly" (Raphael and Sylvie's duet) and "Waltz Number 5".
- Die for Our Ship: The bashing of Marianne in various sites like YouTube.
- Draco in Leather Pants:
- Despite being a Bitch in Sheep's Clothing, a Karma Houdini and not very likeable at all, Rosemary somehow managed to win the 2004 Saimoe tournament, beating Nadja herself on the final no less. Really. Rather ironic that the final round of a popularity contest just happened to be between Nadja and Rosemary and Rosemary won over her. Guess she got the last laugh after all.
- She at least does do something good in the end though, since it's largely her last speech to Nadja about how the nobles suck and that it's better to make your own way through life instead of relying on a life of nobility decided through lineage or inheritance that leads Nadja to make the decision she makes in the final episode. Which might have saved Nadja a lot of future trouble. See Inferred Holocaust.
- Evil Is Cute: The reason for Rosemary's abovementioned Draco in Leather Pants status.
- Fanon: Sylvie is, or was a prostitute. Her past is never addressed, she's fine with dating around despite her commoner heritage and her costume is very inappropriate for the time period.
- Fan-Preferred Couple:
- Nadja/Keith is substantially more popular than Nadja/Francis, probably because of his bad boy persona and outwardly risking more in trying to help her.
- Nadja/Christian also has a following from people who think she should ditch the twins altogether.
- Thomas/Sylvie also has some fans, oddly enough.
- Germans Love David Hasselhoff: Considering how many videos in Spanish, Italian, and French there are on Youtube, it's safe to say that this anime is big in Europe, probably naturally due to its European setting. Spain in particular is somewhat of a subversion, though, because while the series had some decent success, it never reached the popularity Spanish channel RTVE had in mind when it bought the series (to explain, RTVE promoted the series left and right and tried literally to turn it into the next Heidi, Girl of the Alps, an effort that predictably failed due to the legend status of the latter).
- Inferred Holocaust: Nadja's family is Austrian nobility. The show is set nearly at the door to World War I. The show itself has a happy ending, but the Premingers may very well have been decimated in the war as Austria was on the loser side.
- Which REALLY makes it a good thing that Nadja chose to continue being a dancer instead of becoming a noble. She really dodged a bullet there.
- Jerkass Woobie: Initially played straight with Rosemary, though the sympathy could get lost with each act of cruelty she pulls later on. (Though it might be recovered with her last scene, with her acknowledging how wrong she was and bowing out willingly, as well as telling Nadja to treasure her mother, whom Rosemary herself kinda cared for as well).
- Completely averted with Hermann. Despite his final scene (see Alas, Poor Villain / Cry for the Devil on the main page), he's such a bastard that he's never really seen in a sympathetic light by any characters or the audience.
- Played straighter with Marianne and Keith. The first is kinda self-centered and stuck-up but her love for Francis is genuine, she cries at some point since Love Hurts, doesn't lie to Nadja or try to manipulate her, and the scene where she acknowledges her love as impossible and quietly leaves is rather sad. The second is extremely cool as Black Rose, has a decent Freudian Excuse in his mother's death and is humanized by his conflict with Francis, but some of his attitudes to Nadja later in the series can come off as possessive and self-centered, if not very hypocritical.
- Adding to Marianne's case, from the perspective of someone NOT friends with Nadja, Nadja really was causing a lot of trouble for Francis.
- Les Yay: Nadja and Rosemary are a textbook example of Romantic Two-Girl Friendship (what with Rosemary calling herself a princess and Nadja her knight), until the latter snaps and becomes sworn enemy to the former.
- Magnificent Bitch: Rosemary Applefield, believing Nadja was stealing the princess life Rosemary had always dreamed of away from her and casting her aside, becomes a willing participant in Hermann Preminger's schemes and proves herself a deceptive, manipulative, and ruthless schemer in her own right at only age 13. Pretending to be the long lost Nadja Preminger to the Duke and to Nadja's mother, Rosemary charms everyone with her elegance, courtesy, and seeming innocence, which proves useful when implicating the real Nadja, the Black Rose, and even the Applefield orphanage in alleged crimes against her. When Nadja confronts her, Rosemary feigns being an Unwitting Pawn before shredding Nadja's most cherished dress right before her eyes. In a later meeting Rosemary emotionally agitates Nadja into nearly assaulting her, which gets the police to go after Nadja. Nadja returns to prove her identity, but Rosemary counters her claims with quick thinking and skillful manipulation of others in the room. After getting what she'd wanted but finding Victory Is Boring, Rosemary is quick to denounce her alliance with Hermann, who himself has come to fear her, and when proven to be a fraud, she shows herself to be a Graceful Loser and imparts advice to Nadja before leaving the manor of her own accord, receiving no punishment for her actions and even earning Nadja's respect.
- Moral Event Horizon: Once his plans start falling apart, Hermann decides to heck with being sneaky and straight up attempts to shoot his niece, Nadja.
- Values Dissonance:
- More than one fan has been shocked to see that Nadja, a very sweet and kind girl who loves animals, approves of and likes bullfighting and has no problems working in a circus that has a lion tamer and her two mini-lions as a part of their attractions. This is because the series is set in the first decade of the XX century (and right before World War I!), when there was next to none awareness about animal abuse. (Plus, to be fair about Rita and her lions, she comes from a now gone circus with many animal-based acts and, before dying, her parents asked the Troupe to take care of her, Cream and Chocolate.)
- When Sylvie accidentally get tanned, she's horrified and pitches a fit. This is a huge contrast with modern beauty standards, which tend to love attractive people with a good tan.
- The entirety of the episode "A Lie at the Alpine Flower Festival." Tomboyish girls who hang out among boys and lack femininity like Zabbie are accepted today, but the XX century society of the series treats it as cause for Zabbie being a pariah among her peers and disapproved of by her parents. It doesn't help that Zabbie putting aside her tomboyish ways and embracing femninity was treated as the episode's positive conclusion.
YMMV / Ashita no Nadja
