Peak vs. Peak • No Holds Barred • The Ultimate Cat-and-Mouse
Sherlock knows about Kira from the moment the first mysterious heart attack hits the news. He and Mycroft immediately wipe every trace of Sherlock Holmes from public and private records, then disappear into the shadows without hesitation.
The Contenders at Their Absolute Zenith
Light Yagami
This is the post-timeskip Kira. The version who reigned for six straight years without a challenger. Mastery of the Death Note. Misa watching the world with Shinigami Eyes. Global media under indirect influence. Deep infiltration into the NPA and Interpol. And perhaps his coldest era, where emotional attachments no longer slow him down.
Sherlock Holmes (Composite)
This is every continuity of Sherlock at their sharpest merged into one. Doyle’s razor-blade deduction. BBC Sherlock’s physical capability and tech fluency. Mycroft’s near-limitless intelligence reach. Baker Street Irregulars moving quietly all over the map. A man so committed to strategy he will fake his own death on day one and never physically reappear unless it benefits the case.
The Decisive Categories
Raw Deductive and Abductive Reasoning
Light reconstructed L’s location from a staged broadcast with almost no information. He deduced FBI patterns using only behavioral intuition and predicted surveillance down to the wire. Sherlock spots life stories in scuffs, stains, muscle tension and handwriting. Both solve puzzles most people cannot even describe. They simply operate in different intellectual habitats.
Tie.
Long-Term Strategic Planning and Patience
Light waited six quiet years while controlling global crime rates from his home, maintaining perfect public innocence, and sustaining multiple layers of redundancies like Takada, Mikami and the X-Kira system. Sherlock, on the other hand, has never shown a need or desire to play a game that long. His boredom is documented. When the world stops stimulating him, his decisions become risky.
Light wins.
Improvisation Under Pressure
Light improvised his way into Naomi Misora’s trust in minutes, stripped her defenses with pure psychology and left no evidence behind. He almost reversed his fate in the warehouse through a last second confidence trick. Sherlock works best in collapsing environments. Bomb ticking, assassin behind the door, room filling with smoke, his brain simply shifts gear and operates a few steps ahead without hesitation. His consistency under pressure is slightly higher.
Sherlock wins.
Psychological Resilience and Ego Control
Light’s arrogance is a bright red invitation. L used it. Near used it. Mello used it. Light’s god complex makes him brilliant but also predictable in certain emotional situations. Sherlock sees ego the way other people see traffic lights. He identifies arrogance instantly, adjusts for it and rarely lets it cloud his own decisions.
Sherlock wins.
Social Engineering and Manipulation Scale
Light manipulated entire institutions. Police forces, media channels, international investigators and even a Shinigami aligned with him. He inspired a global cult willing to die for his vision. Sherlock manipulates individuals masterfully, but not on that long-term institutional scale. His influence is sharp, not expansive.
Light wins.
Ruthlessness and Willingness to Sacrifice Pawns
Light will remove anyone if the equation demands it. Father figure. Lovers. Partners. Even his own memories were expendable. Sherlock has a cold edge, but he still protects Watson, Mrs. Hudson and his inner circle. These people can be exploited. Light has no such vulnerabilities at this stage.
Light wins.
Information Gathering
Mycroft offers Sherlock staggering intelligence access across Europe and North America, backed by Five Eyes data sharing. Light’s six-year empire gives him deep access across Japan, Interpol channels and significant influence across Asia. Both have global reach, but through different networks and coverage zones. Sherlock’s side has slightly better processing power, but the overall access is very close.
Tie.
Operational Security and True Anonymity
Sherlock can vanish completely. He can remove himself from government files, move through proxies, hire intermediaries, and make sure no one ever sees his real face during the investigation. Light has the terrifying advantage of Misa’s Shinigami Eyes. One photo or fleeting sighting of anyone in Sherlock’s chain can end everything. Sherlock’s op-sec is extremely strong, but it has never been tested against supernatural reconnaissance.
Sherlock wins by a narrow margin.
Counter-Intelligence and Paranoia
Sherlock detects a tail almost instantly, sweeps rooms the moment he enters, and assumes misdirection in every interaction. Light failed to spot L’s cameras. He didn’t detect Near’s tampered notebook. His blind spots only appear against equally brilliant opponents, but they appear nonetheless.
Sherlock wins.
Use of Proxies and Decoys
Light uses Misa, Mikami and Takada with near-perfect compartmentalization. Sherlock weaponizes the Irregulars, builds layered identities and fakes his death so convincingly that even his closest allies believe it. Both excel at staying hidden behind moving parts while they run the real game.
Tie.
Adaptability to Criminal Mindset
Sherlock thinks like criminals at will. He can simulate motives, personality defects, flaws, fears and impulses. Light struggled predicting Near because Light assumes others share at least some part of his emotional logic. Near does not. Sherlock moves fluidly across psychological profiles.
Sherlock wins.
Endgame Execution and Closing the Trap
Light’s warehouse plan would have worked perfectly if Mikami had not acted independently under Near’s psychological pressure. Sherlock’s failure at Reichenbach came only because Moriarty engineered a suicidal no-win setup. Both have faced opponents on their level and both were pushed into extreme measures.
Tie.
Resource Denial and Controlling the Opponent’s Win Condition
Light’s win condition requires one thing.
Name and face.
Sherlock’s win condition requires exposing Kira’s identity or forcing a confession.
Light can manipulate data, eliminate witnesses and erase inconvenient evidence. What he cannot do is magically obtain Sherlock’s identity if Sherlock keeps it nonexistent and buried under layers of misinformation.
Sherlock can deny his identity for as long as necessary. It is easier to block a name from being discovered than it is to prevent a supernatural murder tool from ever finding a photo of one of your proxies over years of global movement.
Sherlock wins.
Pure Lethality and the Death Note Advantage
If Light ever obtains Sherlock’s face and true name, the game ends within seconds. The Death Note makes Sherlock’s margin for error unbelievably small. But it still needs the one piece of information Sherlock is engineered to conceal.
Light wins.
Final Score (14 Categories)
Light Yagami: 5 wins and 1.5 ties = 6.5 points
Sherlock Holmes: 6 wins and 1.5 ties = 7.5 points
Sherlock wins by one of the narrowest margins in any intellectual showdown.
The Real Deciding Factor: Time Pressure Asymmetry
This matchup revolves around time.
Not intelligence.
Not morality.
Not resources.
Time.
Light has infinite time to stay safe. He already owns the world. Every day Sherlock remains hidden is another day Light strengthens his structures, influences more networks, and waits patiently for a single mistake somewhere in Sherlock’s web.
Sherlock cannot afford to wait. He must act. He must investigate. He must put pieces on the board. And every move carries the risk of a sighting. A photograph. A passing glimpse in an airport. Even a minor agent moving independently can be a death sentence if Misa crosses paths with them.
Light can play forever.
Sherlock must play fast.
This asymmetry is why Light still wins a solid minority of scenarios.
Why Sherlock Still Wins More Often
Light only loses when pressured by brilliant, persistent rivals who refuse to bend. L almost exposed him. Near succeeded because he used Mikami’s fanaticism as a psychological trap. That consistency matters.
Composite Sherlock is more relentless than L, more manipulative than Mello and more adaptable than Near. He also has Mycroft, whose analytical power and intelligence network fills the gaps even Sherlock misses.
Sherlock would feed Light’s ego just enough to make him overreach. He would construct a silent trap built on subtle misdirection, careful decoys and pressure applied at the right emotional moment. Then he would strike not when Light is weak, but when Light believes he has already won.
Sherlock’s victory path is fragile and almost surgical. But it exists. And Sherlock excels in situations where the correct move requires precision under extreme stakes.
Final Verdict
Sherlock Holmes wins 6 to 7 out of 10 times.
Never a stomp. Never an easy game. Light has the most lethal tool imaginable, bottomless patience, world-level influence and partners with supernatural sight. Three or four times out of ten, either luck or an unavoidable exposure incident hands him victory instantly.
But in the long run, Sherlock Holmes is built to challenge gods. He is designed to expose the untouchable. To poke the arrogance of the mighty until they step directly into a snare they thought they could avoid.
Winner: Sherlock Holmes
A victory thinner than a razor, earned through discipline, deception and absolute psychological finesse.
Key Points
- Light Yagami’s entire power source is a spooky notebook that can take someone out just by writing their name, as long as he knows the face. Basically the most dangerous stationery item in fictional history.
- Sherlock Holmes operates with zero supernatural help. Just brain power, ridiculous observation skills, and the confidence of someone who solves crimes before breakfast.
- Light specializes in long-term planning. He can stack schemes like a Jenga tower and somehow keep it from falling, at least until someone breathes wrong.
- Sherlock is a master of instant deduction. One quick glance and he knows what someone had for lunch, their credit score, and why they’re lying.
- The Death Note is a guaranteed win only if Light gets the real name and the real face. Without those two, it may as well be a regular school notebook.
- Sherlock’s disguise game is wild. He can blend into any environment, talk his way through anything, and gather information without anyone realizing Sherlock Holmes was literally in their living room.
- Both of them are elite manipulators, so any mental showdown between these two would probably give spectators a headache from how many IQ points are flying around.
- Light’s whole empire collapses the moment someone proves he’s Kira. All that planning, gone like WiFi during a storm.
- Sherlock is great at exposing fake supernatural stuff, but the Death Note is an actual supernatural weapon with no physical traces, so there’s nothing for him to dust for fingerprints.
- The whole fight comes down to who controls the information. If Sherlock manages to hide his identity, he wins the long game. If Light cracks the identity puzzle first, Sherlock’s story ends early.
Fun Facts

- Mycroft would complain that the Death Note is “poorly formatted paperwork with lethal margins.”
- Light would spend two hours crafting a dramatic monologue and Sherlock would interrupt with “Your tie is crooked.”
- Misa would probably accuse Sherlock of being “too plain to be a main character” while he’s solving her entire life in ten seconds.
- Watson would ask what Kira looks like and Sherlock would say “Smug. Very smug.”
- Ryuk would watch the whole game unfold like it’s premium entertainment and still complain there were no apples in the plot twist.
