The Mystic Archives of Dantalian/Trivia
- Genius Bonus: Some of the Phantom Books are actual literary works.
- In episode 12, the Phantom Book that was written by a famous but unspecified assassin morphs into the gun that John Wilkes Booth used to assassinate Abraham Lincoln.
- Hey, It's That Voice!: Durarara!!'s Shizuo and Celty are Huey and Dalian.
- Huey's childhoodfriend and resident Christmas Cake is Mamiko Noto.
- Episode 6's Mabel Nash and her younger sister are Aya Endo and Rina Hidaka, respectively.
- Shout-Out: All of episode 4 is pretty much an anime version of Misery condensed into a half hour.
- And somehow makes the original look tame in comparison.
- From the same episode, a chapter title page (or something similar) in the book Dalian is reading says "Time Considered as a Helix of Semi-Precious Stones", the title of a short story by Samuel Delany.
- Hal's staff greatly resembles Raising Heart. It even goes "Cartridge Load" when he stuffs a Phantom Book at one end to fuel his attack magic.
- In episode 8, a stuffed bear appears in an auction catalog, whose design is noted to have become famous thanks to "a certain president."
- A certain scene in episode 3 looks strikingly similiar to Gainax's earlier mini-series, Houkago No Pleiades
