* AudienceAlienatingPremise: A girl is sent to a school where every single boy is a sexist bastard. That's half the audience lost right there.
* FoeYay: Reiko is (or claims to be, at first) [[HappinessInSlavery quite happy]] to be attached to the males of the academy, and hates everything Sora stands for...and Sora can only think of [[WhatBeautifulEyes what beautiful, strong eyes]] she has.
* GeniusBonus: The code that accompanies the "symbol" on the special weapons is valid [[http://en.wikipedia.org/wiki/Java_(programming_language) Java]].
* LesYay
* MoralEventHorizon: Shinji crosses it by trying to rape Koharu. Luckily [[BigDamnHeroes Sora stopped it.]]
* {{Narm}}: Tougyu's and Shoujou's various deranged [[NightmareFace facial]] [[SlasherSmile expressions]].
* ShockingSwerve: Chapter 22. [[spoiler: Tsuki is the BigBad.]] ''What?'' It doesn't help that the whole thing is presented as [[spoiler: a dream of Sora's. ''Because she fainted from learning that''.]]
* UnintentionallyUnsympathetic: [[spoiler:Tamao calling Sora out for not considering how the boys feel about acting like misogynistic bastards. Apparently Sora not stopping to think "What if these guys feel bad about committing horrible atrocities?" while constantly preventing said horrible atrocities is meant to be poignant, but it just comes across as one big NeverMyFault from the boys' side. This is even more obvious because there are boys like [[TokenGoodTeammate Sumita]] and Akane who ''didn't'' act like misogynistic bastards, but we're supposed to feel bad for the likes of [[AxCrazy Tougyu and Shoujo]] who tortured girls for absolutely no reason. There are good ways to show that boys can also be the victims of misogyny to a degree, this is not one of them.]]
* WhatMeasureIsANonBadass: [[ShrinkingViolet Tomoko]] is a fourteen year old girl in a nightmarish situation... A number of forum goers have decided that she is a useless coward who shouldn't have the privilege of being Sora's slave and deserves whatever happens to her next. Some of those same forum goers have complained about the male characters all being utter bastards. And then there are the ''[[{{GIFT}} really]]'' [[{{GIFT}} scary internet dwellers]] (thankfully not many) who actually think a school like this is a ''good idea''.
* TheWoobie:
** Reversed. Yuki starts in a state of utter misery where her only comfort is a picture of Sora and Koharu. She becomes one of Sora's most confident allies and goes on to take a beating to protect another student.
** All the girls, really.
** Special mention goes to [[spoiler: Tsuki. Orphaned as a child, taken care of by an abusive relative who is essentially the founder of the oppressive Iwahijiri system. She goes insane when she sees Sora "betraying" her, out of fear of being left alone again. Then, she's left with the choice of perfecting the Game, or allowing Sora's life to be ruined from the stigma of the incident. She chooses the former, but tries to tilt things in Sora's favor as much as possible (by appearing as X, and by bugging the system so she has the glove).]]
** Most of the [[spoiler:boys, aswell. Imagine having no choice but to treat half the people you know like shit, knowing ''they'' hate it, and not having any way to change that. Hell is being forced to be someone else.]]
