Most people meet Light Yagami through a notebook that kills, and then spend the next hour arguing about whether he is a hero or a monster. Light first appears in the manga in 2004, in the opening chapter called “Boredom,” according to Wikipedia (open encyclopedia entry), and the sections below separate what the canon shows from what fans assume.
Manga serialization: December 2003 to May 2006 in Weekly Shōnen Jump · Anime broadcast: October 2006 to June 2007 · Creators: Tsugumi Ohba (writer) and Takeshi Obata (artist) · Light’s fate: Dies at the end of the series
Quick snapshot
- Light Yagami is the main protagonist of the Death Note manga, created by Tsugumi Ohba and Takeshi Obata (Wikipedia (open encyclopedia entry))
- No official diagnosis of L Lawliet appears in the sources, and a fan-run guide notes that each adaptation keeps its own canon continuity (Death Note Wiki (fan-run canon wiki))
- The anime ran from October 2006 to June 2007 across 37 episodes on Nippon Television (Wikipedia (open encyclopedia entry))
- Canonically, Light dies at the end of the story, and the idea that he becomes a Shinigami is a fan theory (wikiHow (how-to guide site))
Nine rows, one pattern: the dates and creators are well documented, while the personal details thin out fast.

What anime does Light Yagami appear in?
Light appears across three kinds of Death Note source material: the manga, the Madhouse anime, and several live-action productions. Each version shapes him a little differently.
The table above gives the dates; the lists below show where he appears.
Death Note anime (2006–2007)
- Light is the protagonist of the anime, which aired from October 2006 to October 2006 (Wikipedia (open encyclopedia entry)).
- Madhouse produced the series and Tetsurō Araki directed it, across 37 episodes on Nippon Television (Wikipedia (open encyclopedia entry)).
- Light’s first anime appearance is Episode One, “Rebirth,” according to Death Note Wiki (fan-run canon wiki).
- Mamoru Miyano voices Light in Japanese and Brad Swaile voices him in English (Wikipedia (open encyclopedia entry)).
Manga source material
- Tsugumi Ohba wrote the manga and Takeshi Obata illustrated it, and it ran in Weekly Shōnen Jump from December 2003 to May 2006 (Wikipedia (open encyclopedia entry)).
- Light’s first manga appearance is Chapter One, “Boredom,” in 2004, and his last is “Curtain” in 2006 (Wikipedia (open encyclopedia entry)).
Live-action films
- Tatsuya Fujiwara plays Light in the Japanese live-action film series (Wikipedia (open encyclopedia entry)).
- The Japanese sequel Light Up the New World reveals that Light secretly had a son who was expected to inherit a Death Note (Wikipedia (open encyclopedia entry)).
- Nat Wolff plays Light in the American film, a far more naive and idealistic version with no sister, whose mother died in a hit-and-run (Wikipedia (open encyclopedia entry)).
The implication: the same name carries different personalities across versions, so a trait from the anime is not automatically canon for the manga.
Who is the smartest Death Note character?
Nobody settles this with one test, because each ranking rewards something different: long-range planning, fast deduction, or ruthless adaptability.
How Light’s strategic plans are judged
- Death Note Wiki describes Light as hardworking, talented, a natural genius, and highly perceptive (Death Note Wiki (fan-run canon wiki)).
- According to the same wiki, his hubris and arrogance escalate after he takes on the role of Kira (Death Note Wiki (fan-run canon wiki)).
- The anime makes his turn to Kira immediate and colder, while the manga shows a gradual fall with visible hesitation (ScreenRant (entertainment news site)).
How L’s deductive methods are judged
- L is the primary antagonist and detective, and the two men repeatedly outmaneuver each other in canon (Wikipedia (open encyclopedia entry)).
- According to TV Tropes (trope-analysis wiki), the 2015 TV drama’s Light is eventually outwitted by L in their final confrontation.
- A ranking is only useful if it names its criteria, such as speed, accuracy, or results at the end of the story.
A “smartest” list with no criteria is an opinion, not a finding. Judge Light on planning and L on deduction, and the answer splits into two honest verdicts.
The catch: most rankings skip the criteria step, so a “smartest character” list tells you more about its author than about the story.
Did Light regret killing L?
The sources describe Light’s death scene in detail but do not state clearly that he regrets killing L. That gap decides the question.
How L’s death changes Light’s behavior
- In the anime, Light flees the warehouse when Mikami distracts the room, shows what the wiki calls regret, and sees a figure of L as he dies on an outdoor staircase (Death Note Wiki (fan-run canon wiki)).
- In the manga, Light begs Ryuk to save him, according to the same wiki (Death Note Wiki (fan-run canon wiki)).
What the canon shows about Light’s remorse
- The anime’s production team intended to portray Light as “pitiful” and to present his death more sympathetically than the manga does, according to Wikipedia (open encyclopedia entry).
- The sources in this research do not state that Light regrets killing L, so any regret claim is interpretation.
The anime’s softer portrait is a production choice, not proof of what Light felt. Treat “he regretted it” as a reading of a scene, not a fact of the story.
What this means: a fan who says Light regretted L is reading a scene, and should say so.
Who has a crush on L?
Romance is where the most fan talk and the least canon sit side by side. The sources support very little here.
Did Misa ever kiss L?
- No canonical kiss between Misa Amane and L is documented in the sources, so any kiss is unverified.
- Misa’s romantic focus in the story is Light Yagami, not L.
Did Light and L sleep together?
- No canonical sexual relationship between Light and L is documented in the sources, so the claim stays unverified.
- The story frames the two as rivals, and the 2015 TV drama ends with L outwitting Light (TV Tropes (trope-analysis wiki)).
What girl loves Light Yagami?
- The one romantic focus the sources document runs from Misa Amane to Light Yagami.
- The sources name no other romantic partner for Light.
Does Light Yagami like girls?
- The sources do not address Light’s romantic or sexual interests beyond Misa, so any answer is speculation.
- The canon describes Light as a brilliant but bored genius, a trait profile that says nothing about attraction (Wikipedia (open encyclopedia entry)).
The most-searched romance questions have the least canon behind them, so the honest answer to most of them is “unverified.”
The trade-off: a flat “no” is as unsupported as a flat “yes,” so the fair answer is to name the scene or drop the claim.
Is L Lawliet autistic?
No official diagnosis of L appears in the sources, so any autism label is fan speculation and stays unclear.
How long was L’s lifespan?
- The sources give no canonical figure for L’s lifespan, so this guide does not state one.
- Numbers circulating in fan discussion have no verified source in this research.
Is L Lawliet portrayed as sexually inappropriate?
- The research notes include no source on this question, so this guide makes no claim about it.
- To settle it, check the specific scene in the manga chapter or anime episode and quote it directly.
The catch: diagnosis talk fills the gap that the sources leave, which is why it reads as fact in many fan threads.
Confirmed vs. unclear
The split below is deliberately uneven, because the research confidence is low and the open questions outnumber the settled ones.
- Light Yagami is the protagonist of Death Note, created by Tsugumi Ohba and Takeshi Obata (Wikipedia (open encyclopedia entry)).
- The anime aired from October 2006 to June 2007 (Wikipedia (open encyclopedia entry)).
- Light dies at the end of the series (Wikipedia (open encyclopedia entry)).
- According to Death Note Wiki (fan-run canon wiki), the story has no heaven or hell, and the dead go to Mu.
- Whether L Lawliet is autistic: no official diagnosis appears in the sources.
- L’s lifespan: no canonical figure appears in the sources.
- Whether Light regretted killing L: the sources do not state it clearly.
- Whether Misa kissed L, or whether Light and L had any sexual relationship: nothing is documented.
- Whether the unnamed Shinigami in Relight is Light: according to Death Note Wiki, this is a fan myth (Death Note Wiki (fan-run canon wiki)).
- In-universe death date: Wikipedia’s infobox gives January 28, 2010, with 2013 in the anime (Wikipedia (open encyclopedia entry)).
Four steps separate a canon claim from a fan claim:
- Name the medium. Manga, anime, films, and drama each keep their own canon continuity (Death Note Wiki (fan-run canon wiki)).
- Find the chapter or episode where the scene appears.
- Check whether the claim comes from the source material or from a theory list such as the Death Note Wiki’s Myths page.
- If nothing matches, label the claim unclear, as this guide does for romance and diagnosis.
What this means: a fan claim becomes canon only when a named scene backs it, and most romance claims never reach that bar.
What the creators and anime staff said
Two named voices explain the gap between the manga and the anime, and both reach readers through published interviews and summaries rather than direct statements in this research.
The production team intended to portray Light as “pitiful” and to present his death more sympathetically than in the manga.
Toshiki Inoue, anime series organizer, as paraphrased by Wikipedia (open encyclopedia entry)
The series ended more or less in the manner that they intended for it to end.
Tsugumi Ohba, manga writer, as paraphrased by Wikipedia (open encyclopedia entry)
The trade-off: Inoue’s account explains why the anime reads Light more sympathetically, while Ohba’s account confirms the manga ending was intentional.
Where the canon stops
Any argument about Light’s personal life now has to clear a bar the sources rarely reach: a named scene from a named adaptation. The creators’ statements settle a few questions and leave the rest open, which is useful for readers who want a clear line between story and speculation. For fans arguing about Light and L, the choice is clear: cite the chapter or episode behind the claim, or label it as theory.
