YMMV: Hell Teacher Nube
- Crosses the Line Twice: What the enraged Minki does to the male student body of Doumori Elementary in her introduction ( turning them into panties), and how the girls are supposed to break this spell ( by *wearing* them). Eww.
- Die for Our Ship: If Ritsuko isn't bashed for refusing Nube's advances, she's bashed by Nube x Yukime fans. She can't win, definitely.
- Ho Yay: Nube and Tamamo, though mostly on Tamamo's side.
- Uncanny Valley: 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.
