Detective School Q or Tantei Gakuen Q is a 22 volume manga by Seimaru Amagi that ran from 2001 to 2005. It was adapted into television in 2003, albeit incompletely, spanning a mere forty-five episodes covering only the beginning of the manga, leaving out most of the plot. Later, the series was also adapted into a live action drama.

This story involves a group of students called the Q class of Dan Detective School, founded by Retired Badass Detective Morihiko Dan, the best detective in Japan. These students, led by Kyū Renjō, form a Five-Man Band 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...

This work provides examples of:

  • A-Cup Angst: Sakurako Yukihira is lacking in the mammary department, much to her displeasure.
  • Action Girl: Shino and Yukihira, though each gets hit with the Distress Ball at least once.
  • Adapted Out: 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 and person from DDS he took disguise as, Maki, even King Hades himself didn't appear.
  • Adrenaline Makeover: Subverted. Kuniko drastically changed her looks between a very traumatic incident and her arrival to Class A, but it takes her much more than that to fully blossom.
  • Affably Evil: Anubis.
  • Becoming the Mask: Ryu was supposed to be The Mole, but he grew fond of Kyuu, Megu, Kazuma and Kinta for real. as time passed.
  • Berserk Button:
    • Please don't comment on Megu's panties.
    • And in the case of her older sister Akane, don't mess up with anything in the Minami household.
  • Break the Cutie: More than once case is a painful, slow, tear-jerking breaking process for either victims, Sympathetic Murderers or witnesses, the top examples being 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, Ryu gets progressively broken as he develops more.
  • Brown Note: 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? It was the favorite musical piece of a brilliant player who was handicapped 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). Who end up murdered 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.
  • The Cameo: You can find a cameo of Kindaichi Hajime among the wave of people taking the exam in the first chapter.
  • The Chessmaster: King Hades is the biggest example in this manga, in order to make Ryu his successor with the finale as the proof of his ability. By the concept of "losing hope after betrayal", King Hades purposely enrolled Ryu into DDS to gain True Companions who, at least it's what King Hades think, will doubt Ryu when his identity as grandson of DDS's Arch-Enemy. 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.
  • Chick Magnet: Ryu. Older women, young girls and little girls blush at the sight of him.
  • The Chikan: A whole episode centers on this type of delinquent. One of them attacks Kuniko in a train, and once she recovers from the incoming Heroic B.S.O.D., Yukihira and Megu help her catch him.
  • Collector of the Strange: Onikobe Dokuro, head of DDS research centre, collects skulls. One of them even has a ribbon and is called "Elizabeth".
  • Cruel and Unusual Death: 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.
  • Cut Short: 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 everything in the air, and throwing in a Gainax Ending on top of that.
  • Cute Bruiser: Kuniko, when she stops cowering after someone else's back.
  • Dark Action Girl: Kaori, a rather skilled knife fighter and Master of Disguise
  • Depraved Homosexual: 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 crossdressing Ryu the first time she arrives to 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. 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.
  • Disguised in Drag: Ryu and Tooya was tasked to infiltrate a school regarding a vandalism which may turn into a murder. Unfortunately, since the target school is an all-female school, Ryu was forced to do a total makeover to become a new transfer student.
    • Interestingly, the timing was close to a school play and Ryu is forced to play the prince role in said play, Meaning he disguised as a girl who plays a role of a man!
  • The Dog Was the Mastermind: There's an epic "Whaaaat!?" moment when the high priest behind four murder cases in Kamaikakushi village is revealed to be the cute and innocent Fuuma Mio, who later turns out to be another Anti-Villain as a result of More Than Mind Control that Broke the Cutie.
  • Expy: Kintaro to Kindaichi Hajime; he even has a similar Catch Phrase. Also Cerberus to Yoichi Takato, both refer to perfectly done crime as "art with perfect beauty" and doesn't take it well when plans they've made is ruined and will find out who ruined their plan.
  • Faking the Dead: The businesswoman Hanayo Ichinose tried this to save her enterprise. She got plastic surgery and returned under a disguise to stop her Smug Snake sister's machinations and check on her three children... and ended up dead because the two eldest didn't recognize her and thought she was the Smugsnake's accomplice, so they killed her to protect their baby sister.

  • Handicapped Badass: Dan is a Guile Hero who's wheelchair-bound and is still a pretty good shot. The manga even shows that he's the only one who can see through deception of the first murder plan made by Cerberus which tricks ALL Q-class member and successfully catch him.
  • Heir to the Dojo: Kuniko, whose family has an Aikido dojo.
  • Hot Springs Episode: 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 Sexy Secretary bathing on the other side... and end up beaten by Megu, whom they get to see in the nude. The incident is actually plot-relevant, as it drops hints about the murderer - said Sexy Secretary.
  • Hypercompetent Sidekick: Kerberos.
  • It's Not You, It's My Enemies: Satoru had to leave Kyuu and his mom when he started investigating Meiousei/Pluto, only watching them from a distance. The single time he attempted to approach little Kyu directly, he was kidnapped by Meiousei, and Satoru went all Papa Wolf on them and singlehandedly got his kid back. Few later, though, he was killed.
  • Jack the Ripoff: Psychic Murder Case is one to a similar case happened long ago in National Ability Resrearch Facility where Megu and Saburoumaru went before joining DDS. amusingly, 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.
  • Karma Houdini: Kerberos. As if being Magnificent Bastard wasn't enough, he escapes the heroes at the end too.
  • Magician Detective: Hayato Shiramine is a famous magician who enrolled in Dan Detective School. While he's a minor character since he's in A-class, he shows his his crime-solving ability when he won an analysis duel against Kazumanote .

    • Case-related wise, Jinchu village where "Mayahime Legend Murder Case" occurs can also be read "Hitobashira (Human Pillar)" following the fillage's tradition to burn one of its people on a stake to repel bad luck. Yes, all of the murders happened there has burn-theme.
    • One of first cases Q-class faces is a mysterious disappearance in Kamikakushi Village. In Japan, Kamikakushi means "Spirited away". Almost all of the cases happened related to people missing mysteriously.
  • Meitantei: The main genre.
  • More Than Mind Control: Apparently, what made Miyo Fuuma a murderer.
    • Also applied on several culprits, courtesy of Meiousei itself. Basically, 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.

Then after the red herring's "suicide", an apparent conversation between Meiosei member and one of the suspects also became one. If one is observant, you can see from the contents that there arestill several chapters left.

Largely subverted in Kirisaki Island because 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 Seiryukan Murder Case (manga only) because 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.

  • Stopped Clock: Played with, to the point of becoming running gag. Kyu's watch will stop at when he needs the most outside the case.

  • Team Mom: Shino Katagiri is a responsible and beautiful woman who helps out the kids more than once.

The most notable one is "Hyotan" and its neighboring village "Kamikakushi". Kamikakushi was long erased from the map by people of Hyotan village and was replaced by one half of Hyotan village due to experimental smallpox weapon outbreak using religion cover which worships God related to disease and disaster. Anyone who discovers this secret will be eliminated by name of "Kamikakushi" (spirited away)
