* CargoShip: Even the [[Comicbook/{{Doom}} Doomguy]] never had [[http://static.tvtropes.org/pmwiki/pub/images/ChainsawGirl_9372.jpg this much love]] for his chainsaw.
* EnsembleDarkhorse: Kaoruko is pretty popular, for being an awesome weirdo and incredibly level-headed at the same time.
* FamilyUnfriendlyAesop
* HoYay: Present in Kaoruko's story about her and Fumio's shared past life, as a knight and a common soldier, who fought side by side and were executed together. Both were supposedly male, though they are not drawn as such. Their current incarnations have a distinct LesYay vibe as well.
* WoobieDestroyerOfWorlds: Even after seeing her carve her way through dozens of innocent (if suicidal) people, you can't help feeling sorry for Fumio after reading her InnerMonologue about how she's already dead on the inside and her final wish is to die along with the only boy she ever loved.
