- Fan-Preferred Couple: Several ships have been championed in the comments, particularly Oz/Alice and Gil/Alice. This despite the fact that romance hasn't really factored into the story besides minor Ship Tease between Oz and Hedia (which, even then, is fairly ambiguous on Oz's side).
- Crosses the Line Twice: Readers know Vincent's death is imminent during the opening Advances, and that he is literally out of place in terms of the time period; so, of course, most of the humor is derived from how obviously out of place he feels among everyone else, with him being written as the straight man to the Tale family's antics.
- Family-Unfriendly Aesop: Sometimes, your family members really are burdens, and while you can help support them, you can't carry that weight for them forever—and will only damage things further if you try.
- Genius Bonus: Most places and people have Meaningful Names that reference different famous authors or works of children's literature.
- Jerkass Woobie: Anderson is very aggressive, very rude, and even offensive and dismissive of his brother's very identity. But he's struggled with seeing the little brother he loves suffer with what was presumably a mental illness for most of his life, one that severely negatively impacted his life and his relationships with everyone around him. Further, it's heavily implied that others have taken advantage of Oz's, shall we say, "more distant relationship with the here and now" to legitimately try to take advantage of or even outright hurt him.
- One-Scene Wonder: Shah Cassure has only appeared in one scene in which he ate pages from a book, emitted "creepy rattling nois[es]" that were probably laughter, and made jokes about a serial killer wanting to rip Oz's face off. He is, of course, incredibly memorable, not the least of which because he is also incredibly reminiscent of some of the more cheerfully unstable characters from Pandora Hearts proper.
