History Manga / Yuureitou

* MurderByInaction: [[spoiler:How Reiko/Tetsuo really killed his stepmother. Shibanmushi tied her to the hands of the clock tower to get her to tell him how to operate it, and she would have caved had she not seen her adopted child watching from a window, thinking she was coming to save them. Shibanmushi also retreated, planning to watch Tetsuo stop the clock, but Tetsuo simply watched as revenge for his stepmother almost leaving him to die in the maze as a child.]]

* EvenEvilHasStandards: Amano is surprised to hear from Yamashina that Marube prosecutes rapists ''incredibly'' harshly. It initially comes off as something of a MoralMyopia, since at the time they also believe him to be molesting his daughter, but it later turns out to have been motivated more by [[spoiler:Marube's obsession with his late lover, Onatsu, and his desire to 'become' her]]. (It's also followed with the fact that Marube was incredibly sympathetic towards a man who [[ALoveToDismember hacked apart the body of the woman he was infatuated with]].)

* VillainousIncest: Marube is way too touchy-feely with his daughter. Later we find out [[spoiler:he's not her real father]], but that doesn't make it any less creepy. [[spoiler:He also tries to convince his biological son to have sex with him later.]]

* ArrangedMarriage: Reiko was sold off into an arranged marriage with Shiro by the adoptive mother.
* ArtisticLicenseBiology: When Tetsuo reveals that he has run out of testosterone, his voice becomes more feminine. In reality, going off testosterone won't make your voice feminine even if you've only been on it for a while.

* BluffingTheMurderer: Amano believes that Tetsuo is Shibanmushi, a murderous ghost who kills people who enter the ghost tower, and threatens him with a knife early on in his investigation. Ironically, Tetsuo [[spoiler: turns out to be the one who killed his mother.]]
* BoomHeadshot: [[spoiler:Just as Taichi tells Satoko and Yamashina that he solved a puzzle, Yamashina gets shot in the head by Shibanmushi. He doesn't die from it right away, and passes in Taichi's arms.]]

* ChainedHeat: After getting their hands stuck in one of the mansion's death traps, Marube and Tetsuo were handcuffed together for a time.

* DeathFromAbove: Due to the explosion collapsing the mansion, [[spoiler:Shiro]] is crushed under rubble. [[spoiler:Shiro]] at least gets to make a DyingDeclarationOfLove in the end.

* DrivingQuestion: Who is the Shibanmushi? And in the beginning, who is Tetsuo?

* FanDisservice: The scene of Hanazono's naked corpse being found tied to the clock tower's hands.
* FateWorseThanDeath: [[spoiler: Ultimately, Shibanmushi survived his long fall to the bottom of the clock tower, and became a quadruple amputee. He's in so much pain that not even drugs can dull it, and is now in the care of Tesla, who wants to run all sorts of experiments on him... at least until Marube shot him.]]

* {{Fingore}}: At one point, Shinbanmushi cuts off the fingers of a woman.

* KarmaHoudini: [[spoiler:Marube chooses to die holding onto Onatsu's corpse in the burning Ghost Mansion, so he's never officially prosecuted for his crimes. Tesla and Q also escape, and they'll likely continue their more dubious experiments in addition to saving the occasional life. Technically, on the protagonist side, Tetsuo counts as well - he's never charged with the death of his stepmother or the several partners he had before Amano, although he's already considered the murderer of the former and the others may well have been accidental.]]

* LiarRevealed: [[spoiler:After manipulating and blackmailing Taichi, Marube reveals to Tetsuo that Taichi has being cooperating with him behind his back and basically sold them off to him. This results in a serious fallout for Taichi and Tetsuo.]]

* NeverSuicide: After the floodgate of the village was unlocked, the villagers found Manji's body in a storehouse with a nail driven through his chest. Initially they all thought that he had expected to be punished for it and due to village tradition the population had to be balanced, he took his own life in exchange for that of his grandmother's.
* NippleAndDimed
* NoCelebritiesWereHarmed: Hanazo bears more than a passing resemblance to Creator/AudreyHepburn, even as a Japanese woman.

* PoorCommunicationKills: If Taichi had told Tetsuo about [[spoiler: his agreement with Marube]] earlier, he could have avoided [[spoiler: their breakup.]]

* KarmaHoudini: Tetsuo and Marube.

* AccidentalMurder: [[spoiler: Shino murdering the man at the island.]]

* {{Blackmail}}: Tetsuo uses the truth about his lie about Amano having a wife and money in order to get Amano to investigate the tower for the first time.

* LeaningOnTheFourthWall: Yamashina, when asked what he wants to do with the treasure, responds that he'd like to open a publishing company with stories that focus on societal "deviants". He mentions that by writing about those kinds of people in fiction, they'll start to get normalized in the public's eye and see those same "deviants" as people like them. He even says as much while he's looking ''straight at the audience''.

** [[Tetsuo does this to Shirou by telling him that he loved him all along.]]

* LetThemDieHappy: [[spoiler:Taichi gives Yamashina the satisfaction of thinking that Tetsuo was male all along by pretending to be him as Yamashina dies.]]

* FateWorseThanDeath: [[spoiler: Ultimately, Shibanmushi survived his long fall to the bottom of the clock tower, and became a quadruple amputee. He's in so much pain that not even drugs can dull it, and is now in the care of Tesla, who wants to run all sorts of experiments on him.]]

* CrotchGrabSexCheck: Marube does this to Tetsuo.

** The mansion has a couple of death traps that utilize this by having the ceiling come down on its victims. In-story we see two variations; one that gets its job done quickly, and one that drops the ceiling over the time span of an hour.

* SweetOnPollyOliver: Deconstructed in the village men's cases. They are very much attracted to Taichi in his female disguise, but it's repeatedly pointed out that they haven't seen young women in years.
