History Manga / DetectiveSchoolQ

** Also applied on several culprits, courtesy of [[spoiler: Meiousei itself]]. Basically, [[spoiler: they give you the means to carry your revenge and keep an agent close as a monitor, but when said revenge is foiled, they force you to either kill yourself or murder the person who blows your cover. And if a Meiousei agent is captured by the police, another will activate some sort of {{trigger}} that will make them kill themselves as well.]]

* DepravedHomosexual: Kuroki Ranko in "Bloody Flower Garden" (manga exclusive). Despite being a teacher in a religious girl-only school, she doesn't really hide her homosexual tendencies, as evidenced by her hitting on a crossdressing Ryu the first time she arrives at the teacher's lounge and the rumors circulating among students about how she'd try to show a scar on her cleavage to students she deemed pretty. [[spoiler:The more depraved part of this trope comes when one girl rejected her advances, thus she decided to... killing a bunch of crows and putting them on her desk to torment her.]]

* JackTheRipoff: [[spoiler: Psychic Murder Case]] is one to a similar case happened long ago in National Ability Research Facility where Megu and Saburoumaru went before joining DDS. Amusingly, [[spoiler: the murder trick was Given by Meiosei, but the one who gave the trick to the first and second killers were different members. While the first one was able to make the murder unsolvable, the second member couldn't.]] Ryu even lampshaded it.

* AdaptedOut: Since the anime ended where the story truly began in the manga, lots of character were not adapted into the movie; Cerberus, Sir Charon (who was possibly replaced by Sir Anubis in anime), Thanatos [[spoiler:and person from DDS he took disguise as, Maki, ]]even King Hades himself didn't appear.

* TheChessmaster: King Hades is the biggest example in this manga, in order to make [[spoiler:Ryu]] his successor with the finale as the proof of his ability. [[spoiler:By the concept of "losing hope after betrayal", King Hades purposely enrolled Ryu into DDS to gain TrueCompanions who, at least it's what King Hades think, will doubt Ryu when his identity as grandson of DDS's ArchEnemy. To increase the doubt, he created a murder plan involving Ryu's unlocked past about his dead father (who's not really dead, it's actually one of his henchmen's disguise) and former employees who became the victims. In each murder, traces of Ryu's presence in the crime scene would be present, further driving people into conclusion that Ryu indeed killed them. The truth is, those people died from them ''killing one another with personal motives King Hades planted for years''.]] The plan was so crazy, yet plausible had evidences not been left behind and Kyu not been involved.

* CruelAndUnusualDeath: One of the victims in "Murder of Setsugekka painting" was locked in a what previously used as freezing room from the outside while the temperature was lowered gradually. The shots after that showed her fingers bleeding and the door full of blood and scratch marks, depicting her desperation to get out alive.
* CutShort: The anime faithfully followed the manga and was on track towards greatness when it was cancelled at a point in the manga where the ''real story'' was hardly beginning to unfold, and we mean ''almost 2/3rd of the plot'', leaving virtually [[LeftHanging everything in the air]], and throwing in a GainaxEnding on top of that.

[[spoiler:The more depraved part of this trope comes when one girl rejected her advance, thus she decided to... killing a bunch of crows and putting them on her desk to torment her.]]

* TheDogWasTheMastermind: There's an epic "Whaaaat!?" moment when the high priest behind ''four murder cases'' in Kamaikakushi village is revealed to be [[spoiler:the cute and innocent Fuuma Mio, who later turns out to be another AntiVillain as a result of MoreThanMindControl that [[BreakTheCutie Broke the Cutie]].]]

Few later, though, he was killed.]]

* ScoobyDooHoax: Many of the murders, whether it has Meiosei's interference or not, turn out to be this.

* SerialKiller: Lots of main cases happened around Q-class are this. Largely subverted in [[spoiler:Kirisaki Island]] because [[spoiler:it was a test to determine whether people selected by Morihiko Dan are suitable to be member of Q-class thus no one was killed]] and [[spoiler:Seiryukan Murder Case (manga only)]] because [[spoiler:the four murders happened were actually separate murders committed by ''all the victims'', courtesy of hypnosis and careful planning from King Hades as a plot to make Ryu into his successor.]]
