It was also followed in 2007 by a one volume manga called Tantei Gakuen Q Premium which is a sequel to the original one.

This story involves a group of students called the Q class of Dan Detective School, founded by RetiredBadass Detective Morihiko Dan, the best detective in Japan. These students, led by Kyū Renjō, form a FiveManBand and are task to solve seemingly unsolvable mysteries, as well as to battle a criminal organization led by Pluto who had a past with Morihiko Dan and a mysterious connection with one of the students...

* ArcWord: Meikyuu (labyrinth). Kyu's catchphrase, "If a detective gives up, the case won't be solved!" is written as "tantei wa akirametara, jiken wa ''meikyuu''irinanda!"[[note]]meikyuuiri itself means unsolvable, but it contains for labyrinth[[/note]]. Outside the catchphrase, it's usually thrown a few times as a mystery analogy. The word is also included in [[spoiler:the last keyword to fully unlock Ryu's memory as legitimate descendant of Takumi Kuzuryu]].

* AdaptationalHeroism: [[spoiler:Kaoru Ichinose's brothers']] motive in killing the medium was a bit more noble in anime than in the manga. The anime said they committed the murder because they thought the spirit medium was their aunt's (who underwent an AdaptationalVillainy) accomplice in her scheme to get the family fortune, while in the manga it was implied they didn't want any content in their late mother's will that was advantageous to them to be revealed.

* BreakTheCutie: More than once case is a painful, slow, tear-jerking breaking process for either victims, {{Sympathetic Murderer}}s or witnesses, the top examples being [[spoiler: Miyo Fuuma, the three Ichinose siblings, Kuniko Tooya, Mitsuru Hoshou and both her boyfriend Manabu and her half-sister Arisa, Midori Tachikawa, and Yuri Hitsuji]]. And in-story, [[spoiler: Ryu]] gets progressively broken as he develops more.

* HotSpringsEpisode: Two murders happen in onsens. Only one of these mini-arcs has fanservice, as Kyuu and Kinta first fail to get Ryu naked in the springs and then try to peep on a SexySecretary bathing on the other side... and end up beaten by Megu, whom they get to see in the nude. [[spoiler: The incident is actually plot-relevant, as it drops hints about the murderer - said SexySecretary.]]
* HypercompetentSidekick: Kerberos.

* AdaptationalHeroism: [[Kaoru Ichinose's brothers']] motive in killing the medium was a bit more noble in anime than in the manga. The anime said they committed the murder because they thought the spirit medium was their aunt's (who underwent an AdaptationalVillainy) accomplice in her scheme to get the family fortune, while in the manga it was implied they didn't want any content in their late mother's will that was advantageous to them to be revealed.

* AffablyEvil: Anubis.

* TheCameo: You can find a cameo of [[Manga/TheKindaichiCaseFiles Kindaichi Hajime]] among the wave of people taking the exam in the first chapter.

* 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.

* MeaningfulName: Lots of them. For starters, Q-class is not based on all the rankings found in normal DDS class (from A to D). It was personally selected by Dan Morihiko as "Q"ualified people who will inherit the Detective School.
** Case-related wise, Jinchu village's name, where "Mayahime Legend Murder Case" occurs, can also be read "Hitobashira (Human Pillar)" following the village's tradition to burn one of its people on a stake to repel bad luck. Yes, all of the murders happened there has a burn-theme.

* {{Meitantei}}: The main genre.

* OpenMindedParent: Kyuu's [[NoNameGiven mother]].

* SnuffFilm: One of the case has this theme. [[spoiler: It's mainly for the killer's alibi though, since it's "real-time".]]

* FiveManBand: Surprisingly, it does fit.
** TheLeader: Kyu.
** TheLancer: Ryu.
** TheChick: Megu.
** TheSmartGuy: Kazuma.
** TheBigGuy: Kinta.

** TheHero/TheLeader: Kyu.

* ActionGirl: Shino and Yukihira, though each gets hit with the DistressBall at least once.

* BecomingTheMask: [[spoiler: Ryu]] was supposed to be TheMole, but [[spoiler: he grew fond of Kyuu, Megu, Kazuma and Kinta for real]]. as time passed. This is anime-only.

** If you count the HoYay with Kyuu and the FoeYay with [[spoiler: Anubis]], he falls squarely into EvenTheGuysWantHim.

** TheHero/TheLeader: Kyu
** TheLancer: Ryu
** TheChick: Megu
** TheSmartGuy: Kazuma
** TheBigGuy: Kinta

* LockedRoomMurder: This is featured in a lot of cases. The solution generally involves some manner of sealing the room from the inside in some way that can be performed while outside the room or committing the crime from outside the room.

* BrownNote: The "Banquet of Evil" (Devil's Trill in manga adaptation) violin solo drives a violinist into increasing insanity as soon as he hears it, and it's mentioned that a mysterious person is forcing three other people to hear it as well through cellphone calls. The reason? [[spoiler: It was the favorite musical piece of a brilliant player who was handicapped [[DrivenToSuicide and killed herself]]... after an horrible trap staged by the other four (it was actually three, because her boyfriend has never considered that this could lead to tragedy). [[LoveMakesYouEvil Who end up murdered]] [[SympatheticMurderer by the girl's fellow violinist and the aforementioned boyfriend]]. And had he not done it, they would've died at the hands of the girl's half-sister.]]

* 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 the person from DDS he took his disguise as, Maki]]; even King Hades himself didn't appear.

** And in the case of her older sister Akane, '''don't''' mess up with anything in the Minami household.

* CollectorOfTheStrange: Onikobe Dokuro, head of DDS research centre, collects ''skulls''. One of them even has a ribbon and is called "Elizabeth".

* BecomingTheMask: [[spoiler: Ryu]] was supposed to be TheMole, but [[spoiler: he grew fond of Kyuu, Megu, Kazuma and Kinta for real]]. as time passed.

* 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 comes out. 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 the 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 evidence not been left behind and Kyu not been involved.

* 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... kill a bunch of crows and put them on her desk to torment her.]]

* MoreThanMindControl: Apparently, what made [[spoiler: Miyo Fuuma]] a murderer.
** 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.]]

* MyGodWhatHaveIDone: Besides the ''many'' cases where the murderer of a case realizes how big a mistake killing the victim was, Kinta gets a nasty bout of this trope when he makes Kyu switch cleaning shifts with him and this leads to he and Megu going missing and [[spoiler: having a [[AnimalAssassin highly venomous snake]] sicked on them by a Pluto agent, nearly killing Megu.]]

* 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.]]
