Broken Aesop: While everyone did jump to conclusions about Mizore and Kotsubo and Mizore was the victim in that instance, it was only after she tried freezing Tsukune alive and kill Moka unprovoked, so the episode's attempt to frame Mizore as nothing more than an unfortunate victim of circumstance unfairly judged by her peers is a little less poignant.
Demoted to Extra: In the manga, Mizore and Kotsubo had a history, her having confessed her feelings to him, only for him to sexually assault her, Moka fighting him when he tries it doing it again. Here there is no mention of any subverted Teacher/Student Romance and Inner Moka fights Mizore's ice-constructs after she freezes him instead.
Power Incontinence: At the cliffside, Mizore's powers respond to her mental-state and create ice clones that try to attack everyone indiscriminately.
Sadist Teacher: Kotsubo tries to force himself onto Mizore when she was vulnerable, her track record making it seem like she attacked him unprovoked.
Sick Episode: The day after the Newspaper Club fights Mizore twice, they all wind up with a cold.
Stalker with a Crush: Mizore develops a crush on Tsukune, relating to his articles and keeping a a catalogue of all of his articles (along with lots of creepy notes on them).
Ungrateful Bitch: After Inner Moka saves Mizore from her runaway ice clones, she refuses to thank her for it. Inner Moka immediately responds by kicking her to the ground.
