While the anime versions of Monogatari Series light novels generally stay relatively true to their source material, like all adaptations, there is cut content and a handful of notable changes.
In general, the novels feature extended conversations and hefty narration commentary, while the adaptations have shortened conversations and unique visuals. Occasionally, text flashes are put in place for narration and other text from the novels that is left out. Major plot points are mostly unchanged, though some story content is occasionally cut from the adaptations.
The novels are also notably more meta, featuring even more references to other anime, manga, and light novels and a self aware attitude in which the fourth wall is constantly broken. The novels even reference the anime adaptations, noting how certain parts may be hard to animate and mentioning voice actors of characters.
Changes and Additions
- Little to no narration is present in place for mostly visual story telling.
- Kiss Shot is found in a subway station at the end of a blood trail in which Koyomi follows. In the novel, she's found under a street lamp.
- Eikou Cram School is merely an abandoned building with no blatant signs of ruin. In the novel it is described as being severely worn down, similar to how it is in other adaptations.
- Crows are commonly featured in multiple scenes whereas they were never described in the novel.
- The first film opens with the "catching on fire" scene in place of a monologue in which Koyomi Araragi discusses his regret with having to tell the story. The scene features long moments of him walking around and claiming stairs before finally being set on fire.
- Multiple lines of dialogue.
- Backstories for Dramaturgy, Episode, and Guillotine Cutter are mostly left out.
- Hanekawa bringing action manga for Araragi in order to study how to fight with superpowers.
