- Contest Winner Cameo: The author holds contests for original characters, redraws his favorites in his own style, and puts them on chapter covers. So far, a lot of different ones have made it into the story, three as part of a villainous group and others to lose to new villains. Though it seems like the Dark Student Council is composed of contest winners that weren't part of the Twenty-Three District Project.
- Fan Nickname: One of the translation groups refers to Hikyou Bancho as "Gay Batman" on account of him being an otherwise mundane human with a tendency towards trickery and being Crazy-Prepared, combined with his midriff-baring outfit and whip.
