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.
  • Arc Fatigue: It's like the first 18 chapters are a prologue to this unending school war. If it's any better, one could break the Arachnid Hunt plot in terms of antagonists, so then we have a bunch of small fry, Dinoponera, Sasori, the Army Ant Queen and then Suzumebachi.
    • Dinoponera in particular gets too much build up for someone who unlike Sasori and Suzumebachi has little importance to the story's Myth Arc and who ultimately is completely forgotten about as soon as she's done being a stepping stone to Alice.
  • Ass Pull: A common complaint about the more outrageous stunts the characters pull in order to turn a battle around. Especially Alice and her string antics. Although it's nothing unusual for a shonen manga, the insect documentary expositions make those kind of scenes even more eye-rolling.
    (Geji knocks Oki out and prepares to kill her, only for Oki to keep running and attacking while unconscious)
    Narrator: "Cockroaches have two brains."
  • 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 are all pretty and shapely, but not at all right in the head.
  • Genius Bonus: One can find scenes where characters act like their bugs in some interesting way that aren't given any documentary-esque exposition.
  • Gratuitous Rape: If anyone in either story is to be characterized as a major jerkass, chances are they'll try to rape someone or have it happen by proxy. Although only explicity shown in the seinen spinoff, rape attempts happen regularly enough in both stories that it's hard to avoid discussing them. The series ends with a country-wide rape zombie apocalypse, for crying out loud!
  • He's Just Hiding:
    • Imomushi gets backstabbed by Suzume Bachi while she was focused on fighting Dinoponera. She falls on her face and any plot threads she brought were dropped, with nobody speaking of her again. But isn't it far too much of an unceremonious way for the protagonist of the ongoing prequel to die?
    • Yoriko gets killed by Sasori's deadly red poison. Although her death is portrayed as definitive and she has no powers, readers have been suspicious of her status, arguing that some characters have already survived death in most bizarre ways and that Sasori might have wanted to keep Yoriko alive for later while lying to Alice to break her resolve. As it turns out, Sasori did use her lethal poison on Yoriko, but it only put the twisted-wing parasite girl to sleep due to her poison immunity.
  • Hilarious in Hindsight:
    • When Kabutomushi defeats Abu by destroying the entire floor of the room they were in, Yoriko is relieved to not have been hurt in the process. Kabuto says she won't die... from falling down 3 meters. Yoriko tells her not to lump her with monsters like them. And then Yoriko gets killed by deadly poison instead. Harsher in Hindsight? No, Yoriko also survived that and turns out to be quite a monster herself. Also, the joke was actually foreshadowing how Yoriko gets killed for real by Kabutomushi herself.
    • The Army Ant Queen really wants to know how Alice will react upon being betrayed by someone dear to her, hoping Alice will fall into despair. Thing is, Alice sees it coming and displays anger once she confirms Kuramoto is the one calling the shots among the ants. Moreover, once Yoriko is the one who turns out to be evil, Alice is utterly baffled that Yoriko is somehow a centenarian yakuza boss with psychic powers. And then she gets furious at how this means Yoriko is the source of all her misery.
  • Jerkass Woobie:
    • Yoriko lives alone and has family issues much like Alice does, but even after dropping her bully behavior is harsh to her because she thinks Alice shouldn't let it such things affect her at all. Depressingly enough, once Yoriko opens up to Alice and assures she cares for her, she gets killed. However, she comes back and turns out to be the real boss of the Organization, responsible for all the misery Alice has been going through ever since Suzumebachi left his family. At least it seems Yoriko did lead a unfulfilling life despite pulling Japan's strings for a century and does care for Alice as a friend.
    • Sara may look like a total jackass, but it was her who was the lonely person forced by Kuramoto to be her servant. Since she was a pawn all along and only ever wanted friends and popularity, her breakdown when Kuramoto dies fighting Alice comes off as rather tragic. And the virus in her goes haywire right after, making her brainless along the rest of the student mob.
    • Dinoponera was raised in the battlefield by a psychopathic mercenary and grew rather twisted as a result. Although she only really wants to make friends who can understand her feelings, she grossly misjudges Alice and tries to torture and kill her. The beating she took from Alice was well-deserved, but being paralysed by Sasori right after and thrown to the rape student mob is just uncalled for.
  • 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?
    • The insect lectures from the narrator, which are informative and mostly accurate, are a main draw of the series. Some, however, feel they detract from the action scenes. It's also hard to take seriously how the lectures often expect the biology of insects alone can justify the super powers of each assassin, which range from mundane skills to sci-fi and supernatural abilities.
    • Wire traps don't get much more absurd than they do here, especially since Alice is the main character. The process of crafting the traps is rarely shown, so they just seem to magically spawn all over the planet and make every battle a test of endurance until the enemy inevitably gets All Webbed Up from out of nowhere.
    • At one point, Alice restrains Amenbo underwater and leaves her to drown, but she survives by inflating like a balloon. That's because water striders can float by catching air between hairs on their bodies, ok?
    • The way Kabutomushi reveals her steel plated heart has people flipping off their chairs. Even the arteries are carefully armored! And her arms are spiked. She's just so tongue-in-cheek about it, too.
    • Given Dinoponera is the resident "antagonist who looks like the protagonist and parallels them in practically everything", to get on Alice's level she runs the gauntlet of four characters who have been established as some of the strongest around without breaking a sweat, which easily comes across as ludicrous.
    • Ginyanma makes a shocking return after over 50 chapters and kills an important character. We then learn her bullets have dragonfly wings on them.
    • The details of Yoriko's real role in the story manage to be much more outlandish than anyone could have guessed. This is accompanied by dozens of reaction shots of Alice looking utterly flabbergasted at every single word that comes out of their mouth.
  • Nightmare Fuel: In a gross take on ant breeding, the Queen's Rule virus creates a zombie outbreak of sorts inside a school from orgies that brainwash the students involved. Even readers who called Gratuitous Rape on this manga didn't see that coming. Kuramoto's backstory and motivations are very dark as well, as it's revealed her bodily fluids have always drawn everyone from strangers to her own family into raping her. She just decided to roll with it and attempts to take over the world by turning it into a massive orgy, so Alice kills her. This does not turn the students back to normal and the series ends with them screwing everything in sight until Japan is completely taken over.
  • Signature Scene:
    • Sweaty semi-naked Goki playing with Alice's panties is a staple of manga recommendation threads around the web. And also her brief time as a brainwashed dominatrix in a skimpy leather costume.
    • The infamous scene where Kabutomushi survives having her heart stabbed because it is armored.
  • They Wasted a Perfectly Good Character: When introduced in the main story, Imomushi gets to beat up Alice and has business of her own involving Suzumebachi to get done in the Arachnid Hunt. But then all she does is to get worfed by Dinoponera and backstabbed out of the plot by Suzumebachi in such a way that the readers are not sure if she died. She never comes back, her partner Hanakamakiri never comes to check on things and whatever Suzumebachi was hiding from her is never brought up again.
  • They Wasted a Perfectly Good Plot: A story about a lone girl against an insect-themed yakuza organization becomes a common, if quirky, shonen Fighting Series confined to a school setting. It then ends with a cliffhanger that leaves much of the side plot threads unresolved.
  • 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 was still a obvious reveal to readers who suspected Sara's too-early reveal and over-the-top acting. In the end, though, 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.
    • Yoriko has been from the beginning a suspect of being the boss due to her mysterious wealth and past. Her apparent death at Sasori's hands didn't really fool anyone, either. Even her being an strepsiptera parasite or similar had been called by a person or two due to her possession of the wasp assassins.
  • The Woobie:
    • Alice spent most of her life being looked down upon due to her mental disorder. Her mother commited suicide, her uncle abuses her and the assassin who kidnapped her forces her to kill him after becoming her father figure. While trying to lead a normal life, she is made a target of assassins from all over the world, who wreak havoc at her school. She fights them, but fails to protect Yoriko from Sasori, finds out her mother was actually murdered and that her father is the top organization member she's been planning to kill all along. Also, Yoriko is alive but is actually evil. And then she dies again. Telling Alice she likes her. Oh well.
    • Kuramoto is treated by Sara as a slave and is put through sexual abuse to further her goals. She only endures this because Sara is the closest thing to a friend she ever had. And then it turns out Kuramoto is lying and is the one responsible for much of what is going on at the school. Her excuse for hating everything being that she has sexual mind control powers in the first place because she really had been raped many times since she was small, even by her family. To be fair, it's not like the guys on the Ouran school are any different without her involvement.
    • Alice's mother was left alone by her husband for no apparent reason, so she raised Alice on her own by working on a low-income job, unable to talk to her much. She's apparently overcome by despair and commits suicide. Or rather, Suzumebachi came back after 15 years just to kill her, possessed by the orders of his boss despite having hoped to let his family live peacefully.
  • 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.
