These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: Reimi qualifies for this status when she and her family orchestrate the deaths of over sixty of the sisters' classmates to make room for the kids of possible financial benefactors for the father, Gozo's, political career. Reimi is quite good at putting on the fašade of being the White Sheep, which she uses this to her advantage when she decides to brainwash her students for her personal army. She then gives Ayumi a rigged shotgun, steals all her money, has one of her brainwashed lackeys kill Emi and Gozo, and then laughs about "her poor sisters. During her rooftop battle with Saki, Reimi drops the princess facade and reveals her true Ax-Crazy tendencies as she savages Saki with a whip while screaming at her about her supposedly insane mother.
