- Alternate Continuity: The entry for this trope on the main page has and can be interpreted in several ways: some say Nasu means that 'the chances are just infinitesimally low', while others interpret it as in "it's impossible." It's still part of The Verse, at any rate.
- Base-Breaking Character: Azaka. Some people find her cute and interesting due to having a Brother-Sister Incest backstory that's given a surprising amount of depth and in-universe justification; others find her personality obnoxious or her incestuousness creepy and pandering to Otaku and Harem Genre enthusiasts.
- Big Lipped Alligator Moment: The stop-motion bits at the beginning of each movie imploring viewers to not smoke/make noise/pirate the film/have their phones turned on. It's... er, weird, to say the least.
- They mostly revolve around Type Moon fandom in-jokes and references to similarly surreal sections in other Type Moon works. For example, the yellow-and-green mushroom is Kinoko Nasu's avatar. Other non-KnK characters include super-deformed versions of Fate/Stay Night characters as well as Neko-Arc (who is super-deformed already). The stop-motion for the last movie pans out to show the figures of several other popular Type-Moon characters in the audience (Sacchin's on the bottom-right)
- But hey, its very, very cute.
- Crack Is Cheaper: US releases have always been limited and for absurd amounts of money (including the Blu-Ray boxset that now goes for over $1,000 new.)
- Crowning Music of Awesome: As expected of a soundtrack composed by Yuki Kajiura.
- Ho Yay: Lio does get pretty obsessed with Mikiya at times. And there's the fact that he seems to have a little too much fun kissing him with tongue, even if it is to force a drug down his throat.
- Les Yay: Between Azaka and Shiki, at least in the sixth movie. Most notably when Azaka pins Shiki to the bed and straddles her while trying to take away a knife.
- Moe: The sixth movie plays up Azaka's cuteness for all it's worth.
Smoking is prohibited. Don't burn, be Moe! note
- Moral Event Horizon: Cornelius Alba was never an especially sympathetic character, but after he starts parading Touko's head around like a trophy, then torments Mikiya with it and then starts beating an unconscious Mikiya's head into the wall he has to die.
- Ironically, it's him calling Touko "Dirty Red" that gets him killed. And he wasn't exactly expecting her to come back in an identical clone body, either...
- Seasonal Rot: The sixth movie is generally agreed to be the worst of all the films due to several factors. Changes include the Enjo Kosai plotline becoming Bowdlerized into drugs (which is glaring considering the third movie did not shy away from depicting Rape as Drama), Base Breaker Azaka becoming a Spotlight-Stealing Squad while the novel's actual focus, Kurogiri, was Demoted to Extra, the removal of Shiki's memory loss subplot, and the plot and connection's to the greater storyline becoming nonsensical due to all the Adaptation-Induced Plot Hole|s produced by the changes and emphasis on Azaka. Even without knowledge of the source material and the changes, Movie Six can be downright confusing with how little information is given on the antagonists and how underdeveloped several ideas and plot points are.
- The Woobie:
- Asagami Fujino. She goes through so much abuse that even Nasu has taken to calling her Fujino~n* .
- Tomoe Enjou. Araya even mentions that his origin is worthlessness. This includes the fact that he was NOT responsible for awakening Shiki; she merely awoke at that time. His Heroic Sacrifice was a Senseless Sacrifice. The sword might have helped, though. Ironically, it's the fact that he's so worthless that inspires Shiki to fight Souren.
Shiki: Enjou didn't need to come here, but he will be the reason for your destruction.
