Here are 10 anime that you can rewatch countless times and never get tired of.
The best anime detectives aren’t just smart, they’recomplex characterswhose methods of investigation reveal as much about themselves as the cases they solve. These sleuths navigate moral gray areas while pursuing truth and justice. This list highlights 6 of the most brilliant detectives in anime, ranking them based on their investigative prowess.
6Heinrich Lunge
Inspector Heinrich Lunge from Monster embodies the classic determined detective, whose single-minded pursuit of theserial killerJohan Liebert becomes both his greatest strength and most dangerous liability.
As an investigator for the BKA (German Federal Police), Lunge’s most remarkable trait is his eidetic memory and unusual method of storing information, he physically mimics the people he investigates, copying their mannerisms and thought patterns to better understand them.
This technique proves both brilliant and dangerous when applied to Dr. Kenzo Tenma, whom Lunge wrongly suspects of multiple murders. As Lunge “becomes” Tenma in his mind, he begins unraveling the truth about Johan, though his obsession nearly destroys his career and family in the process.
The series masterfully portrays Lunge’s transformation from a cold, mechanical investigator to someone who questions his own methods. His admission of error regarding Tenma represents one of the most powerful character developments in anime detective stories.
5Shinya Kogami
Psycho-Pass
In thedystopian futureof Psycho-Pass, where a computer system judges citizens' potential for criminality, Shinya Kogami began as an Enforcer, a latent criminal working under the Public Safety Bureau to hunt down other criminals.
Once an exemplary Inspector himself, Kogami’s obsession with solving the Specimen Case led to his demotion when his Crime Coefficient, a measure of criminal potential, rose beyond acceptable levels. This personal fall from grace gave him unique insight into the flaws of the Sibyl System that governs society.
What distinguishes Kogami is his blend of physical prowess and intellectual acumen. Unlike many anime detectives who rely purely on mental analysis, he excels in combat situations while still maintaining sharp deductive reasoning, making him a complete investigator.
His investigation techniques combine traditional detective work with intuitive understanding of criminal psychology. Kogami often places himself in the perpetrator’s mindset, a skill that proved crucial in tracking the series' primary antagonist, Shogo Makishima.
4Ranpo Edogawa
Bungo Stray Dogs
In a world filled with individuals possessing supernatural abilities, Ranpo Edogawa stands apart in Bungo Stray Dogs as a detective who relies solely on his natural intellect, though he believes otherwise.
Named after the famous Japanese mystery writer Edogawa Ranpo, he serves as a central figure in the Armed Detective Agency. What makes Ranpo fascinatingly unique is that he believes he possesses an ability called “Super Deduction” when in reality, his deductive skills are simply extraordinary by normal human standards.
10 Best Detective Based Anime
Detective anime like Detective Conan, Gosick, and Black Butler unravel mysteries with gripping narratives and keen intellect.
His agency chief, Yukichi Fukuzawa, maintains this illusion by giving Ranpo special glasses that supposedly activate his power. This placebo effect allows Ranpo to focus his naturally brilliant mind, solving cases that stump even the most gifted supernatural detectives.
Ranpo’s childish personality and extreme arrogance contrast sharply with his mature analytical abilities. He can determine a person’s occupation, recent activities, and even secrets with just a glance, making him both invaluable and occasionally insufferable to his colleagues.
Death Note
Taking up L’s mantle after his death, Near (real name Nate River) brought a different approach to detective work in Death Note, using toys and puzzles as tools to visualize his complex thought processes.
Raised at Wammy’s House as one of L’s potential successors, Near possessed a more methodical mind than his mentor. While L relied on hunches and risky gambits, Near preferred gathering irrefutable evidence before making his move against Light Yagami.
His most striking characteristic was his emotional detachment. Unlike L, who developed a strange friendship with Light, Near viewed the Kira case as purely a puzzle to be solved, a direct competition with Kira that he was determined to win.
Near’s breakthrough came when he suspected the existence of a fake Death Note. This crucial insight allowed him to orchestrate an elaborate trap at the Yellow Box warehouse, where Light finally exposed himself as Kira when his killing attempt failed.
Though many fans initially resented Near for replacing the beloved L, his methodical approach ultimately succeeded where L failed. Near’s victory over Light provided closure to the series, proving that justice, however delayed, would eventually prevail against Kira’s corrupted ideals.
2Kamonohashi Ron
Ron Kamonohashi’s Forbidden Deductions
Ron Kamonohashi was once the pride of the prestigious detective training school, BLUE, before a mysterious incident led to his ban from detective work, adding a layer of intrigue to his character in Ron Kamonohashi’s Forbidden Deductions.
Despite this prohibition, Ron’s passion for solving cases never diminished. He partners with Totomaru Isshiki, a detective with limited abilities but great determination, creating a dynamic where Ron provides the brainwork while Totomaru takes public credit for solving cases.
What makes Ron exceptional is his “Full Dive” ability, a state of hyper-focused deduction where he can visualize and reconstruct crime scenes with astonishing accuracy. This skill allows him to notice minute details others miss, though it often leaves him physically and mentally drained.
The series brilliantly portrays Ron’s inner struggle between respecting his ban and satisfying his innate desire to solve puzzles. His forbidden status creates constant tension, as each case he solves behind the scenes risks exposing his secret involvement.
1L Lawliet
Death note
L Lawliet stands as the most iconic detective in anime history, with his peculiar mannerisms and unmatched deductive abilities making him the perfect foil to Light Yagami in Death Note.
His disheveled appearance, baggy clothes, perpetual dark circles under his eyes, and a hunched posture, belies a mind of extraordinary caliber. L’s addiction to sweets, particularly strawberry cake and sugar cubes in tea, became as recognizable as his thinking pose, with knees pulled to his chest.
What truly set L apart was his willingness to take enormous risks to solve cases. He famously revealed himself directly to Light Yagami, his prime Kira suspect, to observe his reactions firsthand, a dangerous gambit that ultimately proved his suspicions correct.
His greatest triumph came when he narrowed down Kira’s location to the Kanto region of Japan through a simple television broadcast trick. By airing a criminal’s execution only in one region and observing where deaths occurred, L established the first solid lead in the Kira investigation.
Despite knowing Light was Kira with near certainty, L’s downfall came from underestimating the lengths to which Light would go. His death midway through the series shocked audiences worldwide, yet his legacy continued through his successors, cementing his status as anime’s greatest detective.
