The Private Aiichi Symbiosis Academy was originally a high school for high-class girls. When it became co-ed, the girls, out of fear, asked to be permitted to bring weapons to school. When that was enforced, a five-member vigilante corps-like organization called the "Tenka Goken" (Supreme Five Swords) was also formed.
After many generations, the Five Swords eventually became a group which corrected problematic students, and the academy started proactively accepting such students in order to correct them.
Fudo Nomura was sent to this school after being part of a huge brawl. What will he do when the only options he has after enrolling are being expelled from that school or being corrected the way the rest of the male students there were...by being forced to dress and act like a girl!
Armed Girl's Machiavellism (武装少女マキャヴェリズム, Busō Shōjo Makyaverizumu) is a Japanese manga series illustrated by Karuna Kanzaki and written by Yūya Kurokami. The series began serialization in Kadokawa's Monthly Shōnen Ace magazine in March 2014. An anime television series adaptation by SILVER LINK. premiered on April 2017.
Armed Girl's Machiavellism contains examples of:
- Accidental Kiss: Nono, one of the female students, accidentally pushes Nomura onto Rin's mouth, causing the two to liplock.
- Action Girl: All the female students in Aiichi are armed to defend themselves, but special mention goes to the Supreme Five Swords and the Empress.
- Adaptation Distillation: The anime moved some scenes from the manga and sometimes combines two or more chapters for one episode. Some details were omitted or changed from the manga as well for example...
- One of the reasons Nomura didn't feel up Mary was because he was suffering from blood loss and wasn't thinking straight.
- When Nomura and Rin defeat Warabi in the manga he's allowed to follow through with his threat to make her and her entourage wear mawashi with the cameras rolling while Rin and Mary look on in satisfaction, though he intentionally didn't turn the cameras on to save Warabi's reputation. In the anime however Rin and Mary refuse to let him because of their own experiences with Nomura putting theirs on for them.
- Arc Villain: So far, each arcs has it's own main villain. In order:
- Aiichi Arc: "Empress" Amou Kirukiru.
- Hokkai Arc: "Drunken King" Nonomura Kigisu.
- Armor-Piercing Slap: Nomura hands a well-deserved one to Satori after their fight.
- Artistic License Martial Arts:
- The anime falls into this sometimes, thanks to lackluster animation causing some unrealistic movements.
- Mary's "Flick" move is one that exists in real life, but it's in foil fencing. She's using a combat rapier, which has a much stiffer blade than a sports foil, so it's as hard to flick with it as with any other real sword.
- Axes at School: It started when Aiichi Symbiosis Academy went from an all-girls school to a co-ed school. It allowed the girls to carry weapons to defend themselves from the male student and they have so ever since. Members of the Supreme Five Swords are allowed to wield real swords.
- All Men Are Perverts: Stated as the reason why girls in Aiichi are armed. They think all men are like this and want to protect themselves
- Breather Episode: After Satori's defeat, the story focuses the aftermath of Satori's plan, apologies, and a bit of secret swapping. After that is an incident in with Choka's wig and Kyo-bo's cub going missing and most of cast banding together to find them both. The latter example though ends up distracting everyone from the instant Amou finally makes her move and the shit really starts to hit the fan.
- Broken Faceplate: Nomura breaks Rin's mask at the end of their fight as a direct result of Nono smacking him in the back of the head.
- Curb-Stomp Battle: Amou dishes these out in rapid and merciless succession to Satori, her sister, Warabi, and Kyo-bo while Nomura is busy trying to get his last stamp.
- Defeat Means Friendship: By defeating Rin and Mary, Nomura has unwittingly left them infatuated with him. Warabi's feelings are more on the friendship side, more than happy to pal around with him and even join him on his escapades when she believes that one of the other Five Swords have crossed a line. Satori strides the line between wanting to kill him and developing feelings for him. She'll be malevolent one moment and the next repeating his name in a sugar-coated voice obsessing over the picture of the two of them she had taken as part of her scheme.
- While Nomura doesn't subscribe to the idea that this is completely true, when it actually manages to work, he sees it as one of the ways that people, even those who initially start off hating one another, can bond and become friends without even realizing it at first.
- Double Standard: The reason girls are armed to begin with is to keep boys from taking advantage of them, but they decide that it still isn't enough so they force any boy who transfers into the school to look and act like a girl, pretty much taking away whatever makes the boys act like boys. In a sense, the girls are the ones taking advantage of the boys.
- Moral Myopia: The girls of Aiichi were armed to prevent the boys taking advantage of them, but the girls seem to attack the boys with little to no justification, which is rather ironic.
- One-Gender School: Aiichi was originally an all-girl school and even after becoming co-ed, the female students still dominates the male student. The other symbiosis school, Hokkai, was originally an all-boy school and like Aiichi, it's also recently become co-ed. It seems though, unlike Aiichi, Hokkai allows the female students to occupy important positions. This is shown when one of the members of the "Roku Ou-Ken" (Six King Sword), Hokkai's counterpart to the Supreme Five Sword, is revealed to be a girl.
- Potty Emergency: While Nomura and Rin are disclosing very personal parts of their lives together privately in episode 8 they're unaware that Warabi has awoken and desperately needs to go to the bathroom, but can't bring herself to get up and interrupt them lest they stop opening up to one another. Kyo-bo passes her a bucket. She's not amused. ...She swallows her pride and uses it.
- Shown Their Work: Most of the martial arts used by the characters are actual school of japanese martial arts. The techniques shown are generally very accurate to how it's performed in real-life. This is because author is a martial arts practitioner with extensive knowledge of many martial arts form.
- Stealth Parody: To shounen about martial arts. Although this show features realistic martial art battles, thanks to the author being a martial arts practitioner with extensive knowledge of many martial arts form, between Nomura and the girls, the author clearly does not forget about self-irony. Once Koharu appears and the Hokkai arc starts though, the tone becomes more serious, similar to Shinakoi, without ever abandoning the comedic elements.
- Stealth Sequel: While Tsukuyo being one of the main characters is the first hint that the series is set in the same universe as the author's and illustrator's previous work Shinakoi, it wasn't until Koharu Narukami, Tsukuyo's older half-sister and the main antagonist of Shinakoi, appears that it's made clear that this series is set one year after Shinakoi's ending.
