Detective School Q is the story of a group of young students from Class Q of Dan Detective School (DDS), a prestigious and renowned detective academy founded by Morihiko Dan, the most famous detective in Japan, and the adventures and mysteries they unfold and solve together. They eventually work against Meiosei, a mysterious organization which creates almost fool-proof plans that only a handful of detectives can solve.

• Kyū Renjō • Megumi Ogata • Ryūnosuke Kamiki • Kyū is a bright, optimistic, and highly skilled detective who serves as the leader of Class Q. Known for his logical reasoning and sharp judgment, he openly supports Ryū when others distrust him. He harbors affection for Meg, often teasing her while deeply caring for her. Raised as an only child by his mother, Kyū was unaware that his mentor during childhood was actually his father, Satoru Renjō—Morihiko Dan's partner and right-hand man. Renjō had secretly married Kyū's mother to protect them from the dangers of his profession. After rescuing Kyū from a kidnapping at age five, Renjō later died, prompting Kyū's mother to conceal the truth for years. Once Kyū joined the DDS, she ultimately chose to support his pursuit of detective work. • Ryū Amakusa • Kōichi Tōchika • Ryosuke Yamada • Ryū is the grandson of King Hades, founder of Pluto, who sent him to DDS after his parents' death. Raised by Pluto, he bears the organization's mark on his neck. Isolated in his youth, he saw his home as a prison, shaping his reserved demeanor. Despite his cold exterior, he bonds with Class Q, particularly Kyū, the first to truly understand him. Though more naturally skilled, Ryū acknowledges Kyū's superior detective abilities, attributing them to his persistence and dedication. Ryū suffers from amnesia regarding his childhood, a condition later revealed to be induced by hypnosis. Kyū uncovers his Pluto connection but keeps it secret while aiding his search for the truth. After the hypnosis is lifted, King Hades removes the final mental block, deeming his plan a failure. Ryū then recalls his father's survival and reunites with him. • Megumi Minami "Meg" • Hōko Kuwashima • Mirai Shida • Megumi, commonly known as Meg, is a member of Class Q with an eidetic memory, enabling her to instantly memorize scenes and detect altered evidence. She harbors romantic feelings for Kyū, but Kyū teasingly reciprocates. She previously studied at the Tokyo National Talent Development Research Center alongside Yutaka Saburōmaru and currently lives with her university-student sister, Akane, as her parents work abroad. Upon first meeting Ryū, Meg senses familiarity despite being unable to recall him—an anomaly given her photographic memory. After recovering suppressed memories, she remembers they both attended the Tokyo National Talent Development Research Center. • Kazuma Narusawa • Tomoko Kawakami • Naruki Matsukawa (live-action special), Katsumi Wakaba (live-action drama) • Kazuma is a renowned computer game programmer who assists Class Q with his ever-present laptop. Initially dissatisfied with Class Q's perceived inferior status, he attempts to transfer to Class A but chooses to remain after his classmates support him during a crisis. He maintains a friendly rivalry with Kinta, frequently exchanging jokes while differing in investigative methods. Though a prodigy, Kazuma initially relies on his "lucky" hat for correct deductions but eventually overcomes this dependence. • Kintarō Tōyama • Hideo Ishikawa • Jun Kaname • Commonly known as Kinta, he is the son of a prominent police officer but lives independently after a family dispute, working various part-time jobs. As Class Q's strongest member, he trains in judo, kendo, and karate, possessing exceptional eyesight and olfactory senses. Kinta frequently ridicules Kazuma's technological methods, favoring instinctual detective work instead. His physical prowess and acute senses prove valuable during investigations. • Morihiko Dan • Hideyuki Tanaka • Takanori Jinnai • Dan is the founder and principal of DDS, a renowned detective licensed as Japan's only private investigator permitted to carry firearms. A former police officer, he established Dan Detective Company (DDC) and its subsidiary DDS, developing both into elite institutions with the help of his protégé Satoru Renjō. Their most formidable adversary, the criminal organization Pluto, was seemingly destroyed at great cost—Renjō perished and Dan was left permanently unable to walk. When signs emerge of Pluto's resurgence, the aging Dan creates Class Q, selecting exceptional students to train as potential successors. He intends to evaluate their abilities and appoint his replacement from among them. • Shino Katagiri • Aya Hisakawa • Sawa Suzuki • The loyal assistant of Dan, she assisted Meg, Kyū and Kinta in getting admitted to DDS, having met them during a case. • Shintarō Maki • Ken Narita • Toshihide Tonesaku • DDS's head of forensics, Maki is both a skilled teacher and doctor, and is quite intelligent in his knowledge of medical and forensic science. • Kōtarō Nanami • Shin-ichiro Miki • Tarō Yamamoto • Nanami serves as Dan's trusted assistant, specializing in disguise. He frequently monitors Class Q by posing as suspects during investigations. Though typically carefree—often demonstrating new disguises, including his signature cactus costume with a sombrero—he becomes serious when required. Dan primarily assigns him to protect Class Q during Pluto-related cases. • Yutaka Saburōmaru • Nobuo Tobita • Akiyoshi Nakao • Saburōmaru is an arrogant Tokyo University student who enjoys boasting about his "superiority". He thinks that he will be a qualified detective. Although he has an IQ of 180, he seems too inept in solving mysteries. Saburōmaru is initially in Class A after joining DDS, but later gets demoted to Class B. He knows Meg via the Tokyo National Talent Development Research Center and has a crush on her older sister Akane. • Kingu Hadesu • Gorō Naya • King Hades, born Hoshihiko Kokuō, is Pluto's founder and Ryū's grandfather. The illegitimate son of artist Takumi Kuzuryū and criminal Yurika Kokuō, he retaliated against childhood bullies with an arson disguised as an accident. After rejecting Dan's friendship, he was imprisoned by Takumi in the "House of Dragon" basement, where he scarred his face and kept a blood diary before escaping and killing his father. As Pluto's leader, he attempts to groom Ryū through manufactured despair, but ultimately dies in a fire when his plan fails.
