YMMV: Arachnid

  • Anticlimax Boss: Sasori effortlessly defeats Arc Villain Dinoponera and cruelly throws the girl to be raped, then kills Yoriko from out of nowhere. Alice, however, has less trouble dealing with her mechanical tail than she had figuring out Dinoponera. And then it looks like Kuramoto has Alice at her mercy with the spider girl being none the wiser, but no, Alice had uncovered Kuramoto's ruse all along and was already ready to instantly kill her.
  • Crazy Awesome: Hibiki 'Kamadouma' Fujioka, the Ax-Crazy, Manly Gay, Kahen Rider-obsessed disciplinary council head who liberally dispenses love and justice through repeated kicks to the face. Possibly the best example of how delightfully bizarre he can get is when he tricks his rival, Riokku, into helping him with a Combination Attack by having him punch him as hard as he can in order to build up momentum for a 'Double Rider Kick'. For the record, Riokku's punches can remove heads and go through concrete walls, and he had been trying to murder Hibiki for most of the day.
  • Evil Is Sexy: Sasori, Ageha, Ichijikukobachi and Kuramoto.
  • Les Yay: Even discounting anything involving the canonically lesbian Oki, the author seems incapable of writing or drawing a scene between two female characters that is not dripping with sexual tension. Since most of the cast are out to murder each other, this naturally overlaps with a hefty dose of Foe Romance Subtext.
  • Narm/Narm Charm: Where to begin? Things like Alice's infinite string tricks, Amenbo turning into a balloon to avoid drowning, Kabutomushi avoiding death because she's filled with armor, Dinoponera being cartoonishingly invincible... All justified by mid-battle documentaries on how cool insects are.
  • Signature Scene: Sweaty semi-naked Goki playing with Alice's panties is a staple of manga recommendation threads around the web.
  • Too Cool to Live: Kumo.
  • The Untwist:
    • Sara being the boss can be considered this, because she's shown sending orders about the Arachnid Hunt to Suzume Bachi and is a Obviously Evil Student Council President. However, she's a Red Herring. Even so, Kuramoto being her master can still be a obvious reveal to Genre Savvy readers. However, it turned out neither of them are the Organization boss after all.
    • A few chapters have Dinoponera's opponents wondering just what kind of power she has to dodge and block everything thrown at her, but she had already stated that she and Alice have the same power. Her reveal of Concentration Driving Free to Alice is dramatical, but hardly a surprise.
  • Villain Sue: Two volumes are spent to set up Dinoponera as an unstoppable force that people like Hibiki and Kabutomushi are helpless against, slowing the plot's pace as it takes a while for Alice to meet her or for we to even learn what Dinoponera's past and motivations are. All of this has the effect of making her eventual defeat hard to take seriously. How come she, of all people, didn't notice Alice puppeting her around?
  • The Woobie: Alice spent most of her life being looked down upon due to her mental disorder. She has no family and learning to control her condition makes her a target of an assassin organization, which puts the lives of Yoriko and Oki at risk. Then there's Kuramoto, who is treated by Sara as a slave and is put through sexual abuse to further her goals. However, Kuramoto being Evil All Along makes her more of a Jerkass Woobie instead, considering her circunstances. Same goes for her servant Sara, who really just wants Kuramoto's affections.
    • Jerkass Woobie: Yoriko knows how Alice must feel like as a person with no family, but is cold towards her due to feeling like Alice shouldn't let it affect her at all. Depressingly enough, once Yoriko opens up to Alice and assures she cares for her, she gets killed. Dinoponera's goal in life is to make friends, but her upbringing as a child mercenary gave her some screwed up notions of friendship on top of a vicious and prideful personality.
  • What Do You Mean, It's for Kids?: Despite the fairly dark setting, occasional gore and regular use of rape tropes, the manga is published under the shonen Gangan Joker magazine.
