* CrossesTheLineTwice: What the enraged Minki [[BalefulPolymorph does to the male student body]] of Doumori Elementary in her introduction ([[spoiler: turning them into panties]]), and how the girls are supposed to [[HeroicSacrifice break this spell]] ([[spoiler: by *wearing* them]]). [[{{Squick}} Eww]].
* DieForOurShip: If Ritsuko isn't bashed for refusing Nube's advances, she's bashed by Nube x Yukime fans. She can't win, definitely.
* HoYay: Nube and Tamamo, though mostly on Tamamo's side.
* UncannyValley: Some of the youkai designs (the Kuchisake-onna, for one) are drawn in a more realistic style that makes them look... off compared to the cutesy artstyle of the series.
