Shuriken School/YMMV
- Canon Sue: The cheerleaders Torrance, Missy, and Casey in "Cherry on the Cake". Upon their arrival, nearly every male student becomes infatuated with them. They are able to master a complex fighting technique in the span of a day and are able to easily take down Naginata and his boys despite the latter group being subjected to rigorous training at Katana.
- Draco in Leather Pants: Naginata fits this to a T, being a clear-cut example of Ensemble Darkhorse. The other students of Katana to a lesser extent.
- Evil Is Cool: The Katana School studentss are clearly this, especially Naginata, who doubles as Evil Is Sexy, at least in the eyes of the fandom.
- Foe Yay: Eizan and Naginata. So very much.
- The Scrappy: Kazumi, In-Universe and out.
- Toy Ship: Eizan and Okuni. Being kinda canon definitely helps.
- Also Naginata and Ami, being one of the most popular ships. Doubles as Angel-Devil Shipping.
