[[caption-width:218: The things one does for love.]]
A one shot, three chapter horror manga by YoshitomiAkihito about two Japanese school girls who really want boyfriends. But rather than going through the trouble of getting the attention of a boy, talking to them and just being themselves, they decide on a much quicker way to do so... By hunting mermaids in their school and eating their flesh.

No, really. That's the premise. If you're still skeptical, [[http://www.mangahere.com/manga/school_ningyo/c001 see for yourself]]. A warning - the ending is pretty disturbing and definitely scary. View at your own risk.

!!Examples
* [[spoiler:AndThenJohnWasAZombie]]
* AuthorAppeal: There's only one reason behind the mermaids being portrayed as cute (but creepy) teenagers in classic Japanese school swimsuit...
* TheBadGuyWins: [[spoiler: Haruko wins, but the ending brings up the possibility that one day she will screw up and lose in the worst possible way]].
* BatmanGambit: [[spoiler:Haruko pulls one on Yoshiko - helped along by the fact that the latter had more than one flaw that fed into it]]
* CuteMute: All the mermaids. Obviously cute, and can only make screech sounds.
* DissonantSerenity: The mermaids don't seem the least bit bothered by being stalked by girls trying to kill them, [[spoiler: until one gets brought down]]. Also seen when [[spoiler:Haruko watches them drag Yoshiko away]].
* DownerEnding: [[spoiler: Haruko got Yoshiko turned into a mermaid because Yoshiko is easy prey, and Haruko will move on to the next person - boyfriend, victim, somebody. There is the possibility that she will screw up at some point, and get turned into a mermaid herself, though]].
* EvilPlan: [[spoiler: Brilliantly masterminded by Haruko on the unathletic, weak-hearted Yoshiko from the beginning.]]
* EvilerThanThou: [[spoiler: Haruko happily pulls the trigger and eats the mermaid while Yoshiko is going through her HeroicBSOD / VillainousBreakdown and is doomed by it.]]
* [[spoiler: EtTuBrute?]]
* [[spoiler: FalseFriend]]
* FlawExploitation: [[spoiler: Why Haruko chose to partner up with Yoshiko in the first place. She knew that Yoshiko wouldn't be able to bring herself to kill and eat the mermaid, and so would become one as well. This would get her out of the way and ensure Haruko would then have a weak and easily killable mermaid to hunt the next time she wanted one, since she knew Yoshiko's other flaws would remain after her transformation.]]
* HeroicBSOD / VillainousBreakdown -- [[spoiler: depending on how you view Yoshiko, her loss of composure in the last chapter spells her doom.]]
* ImAHumanitarian: [[spoiler: Anyone who eats mermaid flesh, since mermaids are magically transformed humans. Oh, and if you hunt a mermaid, but decide not to eat her, ''you'' get transformed into a mermaid immediately afterwards. Haruko is so nonchalant about this that she deliberately lures Yoshiko into hunting the mermaid so she can then eat Yoshiko in turn.]]
* LoveMakesYouEvil: Haruko is so [[{{Yandere}} obsessed]] over Tanaka that [[spoiler: she's not only killed and eaten several mermaids, but sets up another girl to be transformed so she can eat ''her'', too]].
* OurMermaidsAreDifferent: Most obviously, they look like schoolgirls in swimsuits, able to "swim" through walls like they were water.
* RaceAgainstTheClock: You'd better be finished by the time sun comes up...
* TheReveal: Let's just say there's a reason those mermaids are there in the first place...
* SlasherSmile: [[spoiler: That creepy-ass grin of Haruko as Yoshiko is turned into a mermaid. You'll know it when you see it.]]
* {{Squee}}: Creepy mermaid sound.
* TomeOfEldritchLore: The Journal detailing the mermaids and how to hunt them. It obviously contains ThingsManWasNotMeantToKnow.
* UnwittingPawn: [[spoiler: Yoshiko can't bring herself to eat Ohara, and that attack of conscience dooms her when Haruko's subsequent EvilerThanThou BatmanGambit comes to fruition.]]
* VillainProtagonist: Both girls but [[spoiler: Haruko's EvilerThanThou Gambit turns Yoshiko into the hapless victim]]
