* AlternativeCharacterInterpretation:
** Norio has gotten a bit of this. Is he actually a gay male, or could he (she?) be a [[{{Transsexual}} trans girl]] instead?
*** {{Jossed}}: WordOfGod says he is born male and still has male anatomy.
** So has Hiro-chan -- on this very wiki, even. [[spoiler:Was her attempt to kill Shunji a cruel method of [[WeCanRuleTogether trying to get Shiina to join her cause]], or was it simply her way of [[SuicideByCop forcing Shiina to kill her]]? And when she says "let's be friends" in the same scene, did that mean she never truly thought of Shiina as a friend in the first place, or did she just mean she wanted Shiina to still be her friend even while [[WoobieDestroyerOfWorlds she's messing up the world to suit herself]]?]]
** What could be the justification for the Sudo gang? Are Bungo and Satomi doing what they believe is right? There are dozens of fan-generated ideals. Sometimes goes into RonTheDeathEater territory.
* CompleteMonster: From MohiroKitoh and his utter disbelief in the notion that ChildrenAreInnocent, we have AlphaBitch Aki Honda, a triumphant example of KidsAreCruel in manga. Aki relentlessly bullies one of the protagonists, Hiro-chan, with daily mockings or beatings. Eventually, she forces her to eat worms. She later sodomizes Hiro-chan with a test tube, threatening to kick her in the stomach with the glass tube inside her. This is what makes Hiro-chan [[{{BreakTheCutie}} utterly snap.]]
* EarWorm: The opening.
* EnsembleDarkHorse: Norio gets the most fanart on pixiv by far.
* FanPreferredCouple: If fan art is anything to go by, the fanbase seems to prefer Tsurumaru with Norio and Shiina with Akira.
* FridgeHorror: Norio's shadow dragon is named VaginaDentata. [[spoiler:Yet it doesn't save him from being brutally raped, tortured and murdered...]]
** Implied by a frame of Moscow's destruction by Shiina: The Su-15 pilot would be [[{{Understatement}} pissed]] to see Moscow and rest of the world destroyed.
* NightmareFuel: Absolutely no end of it, especially in the manga, with one of the standout moments being[[spoiler:Aki Honda's death by ''claw rape.'' [[KarmicDeath She had it coming after what she did to Hiro-chan]], but it's still intensely disturbing.]]
** Easily the most disturbing moment BY FAR, however, is [[spoiler:Norio's death. The worst bits are left off-page, but if anything it makes the entire thing WORSE.]]
* {{Squick}}: Akira pressuring her friend Ishida to have sex with her and loudly masturbating after he couldn't do it. That's not the worst of it by far.
* ViewerGenderConfusion: It seems that a few readers have gone through the entire manga without realising that Norio is male.
* WhatDoYouMeanItsNotForKids: The first chapter/episode and opening theme song aside, ''hoooooh boy!''
* TheWoobie: Akira, most prominently. Given all the crap she goes through, it's hard to not feel at least a ''bit'' sorry for her. Many other characters could qualify as well, though they tend to be either {{Jerkass Woobie}}s or WoobieDestroyerOfWorlds.
