- Alternative Character Interpretation:
- Did Rosemarie intentionally rat out to Louis about Cecilia, Claude and Auguste? Or did she just blab it out without really thinking? To be fair, no matter what you believe, there was no way she could've known that Louis would flip the fuck out in the horrible way that he did.
- We are understand that Rosemarie is in love with Claude exactly as a male. Is this the result of his boyish appearance, or is she just an ordinary anime Lipstick Lesbian, whom attracted to Tomboy girls? Or is she just a pansexual for whom all this does not matter?
- Darkness-Induced Audience Apathy: It becomes difficult to read the story as it progresses, as rare positive characters either suffer or die, while Claude's only Love Interest, with whom he could be expected to have a happy life, is rejected at the very beginning.
- Ensemble Dark Horse: Rosemarie. Although she behaves quite stupid in some scenes, she is still the only person after his father who fully sees Claude as a male and is ready to give him any support. Moreover, she sincerely loves him, even when he refuses her and shows interest in other girls. Moreover, the last chapter implies that she never married, remaining faithful to Claude even after his death.
- Idiot Ball: The last chapter is full of this, when practically all the surrounding Claude begin to behave like assholes. Sirene changes Claude with his brother, the brother himself without any emotions tells him "I forgave her this sin, because you're the girl", after which the psychiatrist technically finishes our main character, suggesting that he is "the wrong male."
- Jerkass Woobie: Louis. He has severe problems, but it does NOT justify his jerk-assery and murderous streak.
- Moe: Maura. Her relationship with Claude is pure Squee!.
- Moral Event Horizon: Louis's murder of his sister and his former lover.
- Narm: Enough and unintentionally, given that this is a tragic love story, although this work is devoid of the author's traditional World of Ham. In particular, most of the surprise scenes look too cartoonish and The Comically Serious, not to mention Luis's cheerful face in the last scene with his appearance and Claude's death scene, where, due to a strange perspective, his corpse looks like a dummy in the air.
- Strangled by the Red String: Claude and Sirene's relationship doesn't get much development, despite how she seems to accept his transgender status without much trouble and their bond being portrayed as the deepest, most meaningful romance of Claude's life. Part of the reason Claude and Rosemarie are a Fan-Preferred Couple is that she gets more Character Development than any of Claude's love interests.
- Unintentionally Unsympathetic: Although Claude is the only character whose actions the author evaluates, it's hard not to be disliked by the Sirene and Cecilia after they reject him, use him or even betray him.
- Values Resonance: Claudine...! takes place in early 20th century France and was published in 1970s Japan, but the pain Claude suffers due to being a trans person is still very relevant. In addition, the manga's treatment of Claude's Transgender status is much more frank, sympathetic and respectful than the treatment of Transgender characters in most modern manga and anime (where they're often portrayed as gay people cranked Up to Eleven or used solely for comic relief). Basically, Claude doesn't go through what's already described — but he's shown as a human person with both flaws and strengths, and who deserves basic respect no matter what.
- Viewer Gender Confusion: A very interesting example. Although we know from the very beginning that Claude is a transgender man, the further the story develops, the more it becomes courageous and the more the reader begins to perceive him as a young man.
YMMV / Claudine...!
