#10 – Remote: A Gritty Crime Thriller with Depth
Author: Seimaru Amagi
Artist: Tetsuya Koshiba
If you like crime dramas with a splash of realism, Remote is worth checking out. It follows Kurumi, a young woman pulled into an elite crime unit led by a mysterious detective who works from a locked room. Why? He’s brilliant—but emotionally broken. The cases are tough, ranging from serial killings to bomb threats, and each chapter peels back layers of psychological and social commentary.
It’s like Silence of the Lambs meets CSI—with a strong dose of Japanese noir.
#9 – Q.E.D.: Iffotatemasu Shoumei: Logic at Its Finest
Author and Artist: Motohiro Katou
Q.E.D. is one of those underrated gems that truly respects your intelligence. The main character, Sou Touma, is a genius with a Harvard education but chooses to return to high school in Japan. Why? Because he loves solving puzzles, especially crimes. The mysteries are grounded in real logic, and the manga often dives into science, math, and even linguistics.
It’s not flashy—but if you want a mystery manga that rewards careful reading and deduction, this one’s for you.
#8 – Detective School Q: The Perfect Mix of Youth and Mystery
Author: Seimaru Amagi
Artist: Fumiya Satou
Imagine a high school for aspiring detectives—Detective School Q makes that fantasy real. The story follows a group of talented teens at the Dan Detective School (DDS), who tackle everything from standard thefts to full-blown murder mysteries. Each member of the team has a unique skill, and together, they crack seemingly impossible cases.
It’s like Scooby-Doo grew up, got smarter, and moved to Japan. The chemistry between the characters adds charm, and the twists will keep you guessing.
#7 – Spiral: The Bonds of Reasoning – A Psychological Chess Match
Author: Kyō Shirodaira
Artist: Eita Mizuno
Spiral centers on Ayumu Narumi, the younger brother of a famous detective who’s mysteriously vanished. What starts as a simple search quickly turns into a psychological war involving the enigmatic “Blade Children.” The cases here aren’t just about finding clues—they’re about unraveling human motives, fear, and morality.
If you’re a fan of deep thinking and morally grey characters, Spiral will hit all the right notes.
#6 – Kindaichi Case Files: Classic Whodunits with Twists
Author: Yōzaburō Kanari
Artist: Fumiya Satō
Hajime Kindaichi is your average lazy high schooler… until a crime happens. That’s when his brilliant detective instincts, inherited from his legendary grandfather, kick in. The manga follows a classic structure—locked rooms, isolated islands, elaborate setups—but it always throws in a shocking twist.
If you love Agatha Christie-style mysteries, this series is basically her spiritual manga successor. With over 70 volumes, you’ll never run out of cases to solve.
#5 – Pluto: A Sci-Fi Mystery Like No Other
Author and Artist: Naoki Urasawa (based on Osamu Tezuka’s work)
This isn’t your average detective story. Pluto is a reimagining of a classic Astro Boy arc, but it’s transformed into a dark, brooding mystery set in a futuristic world where robots and humans coexist. The protagonist, Gesicht, is a robot detective investigating a string of murders… of other advanced robots.
It’s not just a mystery—it’s a meditation on identity, prejudice, and what it means to be human. Pluto is short (just 8 volumes) but incredibly powerful.
#4 – Death Note: A Battle of Wits and Justice
Author: Tsugumi Ohba
Artist: Takeshi Obata
You probably knew this one would show up. Death Note isn’t a traditional detective manga, but the battle between Light Yagami and L is one of the smartest mind games ever written. When Light gains the power to kill anyone by writing their name, it becomes a deadly game of cat and mouse between him and the world’s greatest detective.
Every chapter is packed with tension and strategy. You’ll find yourself questioning who the real villain is—and that’s exactly the point.
#3 – Monster: A Dark, Psychological Masterpiece
Author and Artist: Naoki Urasawa
What happens when doing the right thing leads to unspeakable consequences? Monster follows Dr. Kenzo Tenma, a surgeon who saves the life of a boy who grows up to become a remorseless killer. Now Tenma must track him down and stop the monster he helped create.
This isn’t just a detective manga—it’s a slow-burning thriller filled with haunting characters, moral dilemmas, and plot threads that span across Europe. Urasawa weaves a tale that feels more like a novel than a comic.
#2 – Case Closed (Detective Conan): Timeless and Clever
Author and Artist: Gosho Aoyama
For over 25 years, Detective Conan has delivered mystery after mystery, and it’s still going strong. The plot is simple but genius: Shinichi Kudo, a teen detective, gets poisoned and shrinks into a child. Under the alias Conan Edogawa, he continues solving crimes while hunting down the shadowy organization that attacked him.
The cases are incredibly varied—some are humorous, others tragic, and many will leave you scratching your head until the final reveal. It’s the Sherlock Holmes of manga, and fans of puzzle-solving will love it.

Emma, Norman, and Ray must outsmart not just their caretakers, but a whole system designed to keep them trapped. Every arc has layers of mystery, hidden messages, and jaw-dropping twists. It’s intense, emotional, and brilliantly crafted.
