Death Note

Death Note (stylized in all caps) is a Japanese manga series written by Tsugumi Ohba and illustrated by Takeshi Obata. It was serialized in Shueisha's manga magazine Weekly Shōnen Jump from December 2003 to May 2006, with its chapters collected in 12  volumes. The story follows Light Yagami, a genius high school student who discovers a mysterious notebook: the "Death Note", which belonged to the Ryuk, and grants the user the supernatural ability to kill anyone whose name is written in its pages. The series centers around Light's subsequent attempts to use the Death Note to carry out a worldwide massacre of individuals whom he deems immoral and to create a crime-free society, using the alias of a god-like vigilante named "Kira", and the subsequent efforts of an elite Japanese police task force, led by enigmatic detective L, to apprehend him.

A 37-episode anime television series adaptation, produced by Madhouse and directed by Tetsurō Araki, was broadcast on Nippon Television from October 2006 to June 2007. A light novel based on the series, written by Nisio Isin, was also released in 2006. Additionally, various video games have been published by Konami for the Nintendo DS. The series was adapted into three live-action films released in Japan in June, November 2006, and February 2008, and a television drama in 2015. A miniseries titled Death Note: New Generation and a fourth film were released in 2016. An American film adaptation was released exclusively on Netflix in August 2017, and a series is reportedly in the works.

Death Note media, except for video games and soundtracks, is licensed and released in North America by Viz Media. The episodes from the anime first appeared in North America as downloadable from IGN before Viz Media licensed it. The series was aired on YTV's Bionix programming block in Canada and on Adult Swim in the United States with a DVD release following. The live-action films briefly played in certain North American theaters, in 2008, before receiving home video releases. By April 2015, the Death Note manga had over 30 million copies in circulation, making it one of the best-selling manga series.

Plot
In Tokyo, a disaffected high school student named Light Yagami finds the "Death Note", a mysterious black notebook with rules that can end anyone's life in seconds as long as the writer knows both the target's true name and face. Light uses the notebook to kill high-profile criminals and is visited by Ryuk, a "shinigami" and the Death Note's previous owner. Ryuk, invisible to anyone who has not touched the notebook, reveals that he dropped the notebook into the human world out of boredom and is amused by Light's actions.

Global media suggest that a single mastermind is responsible for the mysterious murders and name them "Kira" (キラ). Interpol requests the assistance of the enigmatic detective L to assist in their investigation. L tricks Light into revealing that he is in the Kanto region of Japan by manipulating him to kill a decoy. Light vows to kill L, whom he views as obstructing his plans. L deduces that Kira has inside knowledge of the Japanese police investigation, led by Light's father, Soichiro Yagami. L assigns a team of FBI agents to monitor the families of those connected with the investigation and designates Light as the prime suspect. Light graduates from high school to college. L recruits Light into the Kira Task Force.

Actress-model Misa Amane obtains a second Death Note from a named Rem and makes a deal for  eyes, which reveal the names of anyone whose face she sees, at the cost of half her remaining lifespan. Seeking to have Light become her boyfriend, Misa uncovers Light's identity as the original Kira. Light uses her love for him to his advantage, intending to use Misa's eyes to discern L's true name. L deduces that Misa is likely the second Kira and detains her. Rem threatens to kill Light if he does not find a way to save Misa. Light arranges a scheme in which he and Misa temporarily lose their memories of the Death Note, and has Rem pass the Death Note to Kyosuke Higuchi of the Yotsuba Group.

With memories of the Death Note erased, Light joins the investigation and, together with L, deduces Higuchi's identity and arrests him. Light regains his memories and uses the Death Note to kill Higuchi, regaining possession of the book. After restoring Misa's memories, Light instructs her to begin killing as Kira, causing L to cast suspicion on Misa. Rem realizes Light's plan to have Misa sacrifice herself to kill L. After Rem kills L, she disintegrates and Light obtains her Death Note. The task force agrees to have Light operate as the new L. The investigation stalls but crime rates continue to drop.

Four years later, cults worshipping Kira have risen. L's potential successors are introduced: Near and Mello. Mello joins the mafia whilst Near joins forces with the US government. Mello kidnaps Director Takimura, who is killed by Light. Mello kidnaps Light's sister and exchanges her for the Death Note, using it to kill almost all of Near's team. A Shinigami named Sidoh goes to Earth to reclaim his notebook and ends up meeting and helping Mello. Light uses the notebook to find Mello's hideout, but Soichiro is killed in the mission. Mello and Near exchange information and Mello kidnaps Mogi and gives him to Near. Kira's supporters attack Near's group, but they escape. Shuichi Aizawa, one of the task force members, becomes suspicious of Light and meets with Near. As suspicion falls again on Misa, Light passes Misa's Death Note to Teru Mikami, a fervent Kira supporter, and appoints newscaster Kiyomi Takada as Kira's public spokesperson. Near has Mikami followed whilst Aizawa's suspicions are confirmed. Realizing that Takada is connected to Kira, Mello kidnaps her. Takada kills Mello but is killed by Light. Near arranges a meeting between Light and the current Kira Task Force members. Light tries to have Mikami kill Near as well as all the task force members, but Mikami's Death Note fails to work, having been replaced with a decoy. Near proves Light is Kira discovering Mikami had not written down Light's name. Light is wounded in a scuffle and begs Ryuk to write the names of everyone present. Ryuk instead writes down Light's name in his Death Note, as he had promised to do the day they met, and Light dies.

One year later, the world has returned to normal and the Kira Taskforce Members are conflicted over whether they made the right decision. Meanwhile, cults continue to worship Kira.

C-Kira (one-shot sequel)
Three years later, Near, now functioning as the new L, receives word that a new Kira has appeared. Hearing that the new Kira is randomly killing people, Near concludes that the new Kira is an attention-seeker and denounces the new Kira as "boring" and not worth catching. A named Midora approaches Ryuk and gives him an apple from the human realm, in a bet to see if a random human could become the new Kira, but Midora loses the bet when the human writes his own name in the Death Note after hearing Near's announcement. Ryuk tells Midora that no human would ever surpass Light as the new Kira.

a-Kira (one-shot sequel)
Another ten years later, Ryuk returns to Earth and gives the Death Note to Minoru Tanaka, the top-scoring student in Japan, hoping that he will follow in Light Yagami's footsteps. On explaining the rules to Minoru, Ryuk is surprised when he returns the notebook and tells him to return it and his memory of their encounter to him in two years' time. Two years later, on receiving the notebook back from Ryuk, Minoru reveals he has no plans to use it himself but rather he plans to auction it off to the governments of the world, with Ryuk's help sending his offer out as "a-Kira", having waited two years until he was old enough to have a bank account to allow his plan to work. Elsewhere, Near (as L) is revealed to be developing technology meant to track and eventually find a method of destroying Shinigami, although it is not yet advanced enough to be useful. After selling the Death Note to U.S. President Donald Trump for a sum that would ensure every Japanese citizen under the age of 60 would be financially set for life, Minoru relinquishes his ownership and memory of his plan to Ryuk, assuring his own anonymity, while Trump is left unable to use the Death Note after the King of Death creates a new rule disallowing the Death Note to be sold, and he secretly returns it to Ryuk. Minoru collapses to the ground in the bank after withdrawing his savings. It is revealed that Ryuk wrote his name in the Death Note next to Light's. He longs for a human who will use the notebook for a longer period of time.

Development
The Death Note concept derived from a rather general concept involving Shinigami and "specific rules". Author Tsugumi Ohba wanted to create a suspense series because the genre had some suspense series available to the public. After the publication of the pilot chapter, the series was not expected to receive approval as a serialized comic. Learning that Death Note had received approval and that Takeshi Obata would create the artwork, Ohba said, they "couldn't even believe it". Due to positive reactions, Death Note became a serialized manga series.

"Thumbnails" incorporating dialogue, panel layout and basic drawings were created, reviewed by an editor and sent to Takeshi Obata, the illustrator, with the script finalized and the panel layout "mostly done". Obata then determined the expressions and "camera angles" and created the final artwork. Ohba concentrated on the tempo and the amount of dialogue, making the text as concise as possible. Ohba commented that "reading too much exposition" would be tiring and would negatively affect the atmosphere and "air of suspense". The illustrator had significant artistic licence to interpret basic descriptions, such as "abandoned building", as well as the design of the Death Notes themselves.

When Ohba was deciding on the plot, they visualized the panels while relaxing on their bed, drinking tea, or walking around their house. Often the original draft was too long and needed to be refined to finalize the desired "tempo" and "flow". The writer remarked on their preference for reading the previous "two or four" chapters carefully to ensure consistency in the story.

The typical weekly production schedule consisted of five days of creating and thinking and one day using a pencil to insert dialogue into rough drafts; after this point, the writer faxed any initial drafts to the editor. The illustrator's weekly production schedule involved one day with the thumbnails, layout, and pencils and one day with additional penciling and inking. Obata's assistants usually worked for four days and Obata spent one day to finish the artwork. Obata said that when he took a few extra days to color the pages, this "messed with the schedule". In contrast, the writer took three or four days to create a chapter on some occasions, while on others they took a month. Obata said that his schedule remained consistent except when he had to create color pages.

Ohba and Obata rarely met in person during the creation of the serialized manga; instead, the two met with the editor. The first time they met in person was at an editorial party in January 2004. Obata said that, despite the intrigue, he did not ask his editor about Ohba's plot developments as he anticipated the new thumbnails every week. The two did not discuss the final chapters with one another and continued talking only with the editor. Ohba said that when they asked the editor if Obata had "said anything" about the story and plot, the editor responded: "No, nothing".

Ohba claims that the series ended more or less in the manner that they intended for it to end; they considered the idea of L defeating Light Yagami with Light dying but instead chose to use the "Yellow Box Warehouse" ending. According to Ohba, the details had been set "from the beginning". The writer wanted an ongoing plot line instead of an episodic series because Death Note was serialized and its focus was intended to be on a cast with a series of events triggered by the Death Note. 13: How to Read states that the humorous aspects of Death Note originated from Ohba's "enjoyment of humorous stories".

When Ohba was asked, during an interview, whether the series was meant to be about enjoying the plot twists and psychological warfare, Ohba responded by saying that this concept was the reason why they were "very happy" to place the story in Weekly Shōnen Jump.

The notebooks
The core plot device of the story is the "Death Note" itself, a black notebook with instructions (known as "Rules of the Death Note") written on the inside. When used correctly, it allows anyone to commit a murder, knowing only the victim's name and face. According to the director of the live-action films, Shusuke Kaneko, "The idea of spirits living in words is an ancient Japanese concept.... In a way, it's a very Japanese story".

Artist Takeshi Obata originally thought of the books as "Something you would automatically think was a Death Note". Deciding that this design would be cumbersome, he instead opted for a more accessible college notebook. Death Notes were originally conceived as changing based on time and location, resembling scrolls in ancient Japan, or the Old Testament in medieval Europe. However, this idea was never used.

Themes
Writer Tsugumi Ohba had no particular themes in mind for Death Note. When pushed, he suggested: "Humans will all eventually die, so let's give it our all while we're alive". In a 2012 paper, author Jolyon Baraka Thomas characterised Death Note as a psychological thriller released in the wake of the 1995 Tokyo subway sarin attack, saying that it examines the human tendency to express itself through "horrific" cults.

Pilot chapter
The Death Note process began when Ohba brought thumbnails for two concept ideas to Shueisha; Ohba said that the Death Note pilot, one of the concepts, was "received well" by editors and attained positive reactions from readers. Ohba described keeping the story of the pilot to one chapter as "very difficult", declaring that it took over a month to begin writing the chapter. He added that the story had to revive the killed characters with the Death Eraser and that he "didn't really care" for that plot device.

Obata said that he wanted to draw the story after he heard of a "horror story featuring ". According to Obata, when he first received the rough draft created by Ohba, he "didn't really get it" at first, and he wanted to work on the project due to the presence of and because the work "was dark". He also said he wondered about the progression of the plot as he read the thumbnails, and if Jump readers would enjoy reading the comic. Obata said that while there is little action and the main character "doesn't really drive the plot", he enjoyed the atmosphere of the story. He stated that he drew the pilot chapter so that it would appeal to himself.

Ohba brought the rough draft of the pilot chapter to the editorial department. Obata came into the picture at a later point to create the artwork. They did not meet in person while creating the pilot chapter. Ohba said that the editor told him he did not need to meet with Obata to discuss the pilot; Ohba said "I think it worked out all right".

Anime adaptation
Tetsurō Araki, the director, said that he wished to convey aspects that "made the series interesting" instead of simply "focusing on morals or the concept of justice". Toshiki Inoue, the series organizer, agreed with Araki and added that, in anime adaptations, there is a lot of importance in highlighting the aspects that are "interesting in the original". He concluded that Light's presence was "the most compelling" aspect; therefore the adaptation chronicles Light's "thoughts and actions as much as possible". Inoue noted that to best incorporate the manga's plot into the anime, he "tweak[ed] the chronology a bit" and incorporated flashbacks that appear after the openings of the episodes; he said this revealed the desired tensions. Araki said that, because in an anime the viewer cannot "turn back pages" in the manner that a manga reader can, the anime staff ensured that the show clarified details. Inoue added that the staff did not want to get involved with every single detail, so the staff selected elements to emphasize. Due to the complexity of the original manga, he described the process as "definitely delicate and a great challenge". Inoue admitted that he placed more instructions and notes in the script than usual. Araki added that because of the importance of otherwise trivial details, this commentary became crucial to the development of the series.

Araki said that when he discovered the Death Note anime project, he "literally begged" to join the production team; when he joined he insisted that Inoue should write the scripts. Inoue added that, because he enjoyed reading the manga, he wished to use his effort.

Light novels
A light novel adaptation of the series has been written by Nisio Isin, called Death Note Another Note: The Los Angeles BB Murder Cases. The novel was released by Shueisha on August 1, 2006. It serves as a prequel to the manga series, with Mello narrating the story of L's first encounter with Naomi Misora during the Los Angeles "BB Serial Murder Case" mentioned in volume 2 of the manga. Besides Naomi's character, the novel focuses on how L works and one of the criminals L has to chase down.

Viz released the novel in English on February 19, 2008. The film L: Change the World was also adapted into a light novel with the same name on December 25, 2007, by "M", While the novel is similar to the film, there are many significant changes to the plot (for example, Near is not a Thai boy, but the same Near that appears in the manga).

Anime
The Death Note anime, directed by Tetsurō Araki and animated by Madhouse, began airing on Nippon TV on October 4, 2006, and finished its run on June 27, 2007, totaling 37 episodes. The series aired on the network "every Tuesday at 0:56", which is effectively Wednesday. The series was co-produced by Madhouse, Nippon Television, Shueisha, D.N. Dream Partners and VAP. In North America, the series was licensed by Viz for residents in the United States to use "Download-to-Own" and "Download-to-Rent" services while it was still airing in Japan. This move was seen as "significant because it marked the first time a well known Japanese anime property was made legally available in the United States for domestic audiences to download while the title was still airing on Japanese television". The downloadable episodes contained the original Japanese audio track and English subtitles, and were made available through IGN's Windows-only Direct2Drive service.

In 2007, the first three volumes of Death Note were on the American Library Association's 2007 Great Graphic Novels for Teens Top Ten list.

Douglas Wolk of Salon said that a rumor circulated stating that the creators intended to create Death Note to last half as long as its actual run and Ohba and Obata had been persuaded to lengthen the storyline when Death Note's popularity increased, noting that the rumor "makes sense, since about halfway through the series, there's a point that seems like a natural ending". In addition, he said that fans wrote "thousands" of Death Note fan fiction stories and posted them on the internet. In 2006, Japanese fans pointed out the similarities between Death Note and the 1973 one-shot manga The Miraculous Notebook (不思議な手帖) by Shigeru Mizuki. Comipress reported that the only difference between the story and Death Note is that there are no shinigamis.

Anime News Network writer Zac Bertschy called Death Note a "surprisingly gripping and original suspense tale that raises a handful of interesting questions about morality". He noted that the difference between the series and other manga from the same demographic was very big due to the murders the main character commits as well as how he hides his identity of Kira. Although Bertschy mentioned some manga readers will be surprised with the dark themes of Death Note, he praised the series for its "great art, great story, [and] compelling characters". Briana Lawrence from the same website stated that what makes Death Note so interesting is that there is no villain, "instead it had two opposing sides that both believe in the same thing: justice". She felt that once vital characters fading into the background, the ending brings back what the fans loved about the first volume and the supporting cast are "given a chance to shine". She also mentioned that the epilogue made no mention of what happens with Misa Amane and how Near and Mello were still treated like parts of L. Julie Rosato from Mania Entertainment found the story to be very entertaining, having liked Light's development in the story and L's introduction as well as how the latter starts suspecting the former's identity. Additionally, she praised the story as it is "building a climax" with each detail introduced in the first chapter, making the reader look forward to upcoming chapters. Jolyon Baraka Thomas, in a Japanese Journal of Religious Studies article, describes the manga as having a "somber narrative" with a "dark cast". Obata's art is "[rendered] in stark strokes characterized---fittingly---by a complex interplay of light and shadow".

Anime
On Rotten Tomatoes, the show holds an approval rating of 100%, based on 14 reviews, with an average rating of 8.5/10. The website's critical consensus reads: "Death Note is an exceptional anime that poses profound questions about justice and murder, all while delivering a supremely satisfying tale of tactical one-upmanship between a detective and killer." The Death Note anime was one of the series to win Best TV Anime at the 2007 Tokyo International Anime Fair. The anime was commended with Tom S. Pepirium of IGN saying that Death Note's "heavy serialized nature" is what "makes the show so engaging and discussion worthy". Pepirium, saying that translating Death Note is "no small task", stated that Stephen Hedley created an English dub with "nothing clunky". He added that Karl Willems, director of the dub, assembled a "stunning voice cast of professionals" with a "solid tone minus some of the cheesy yelling and screaming of other dubs". On the NPR show Fresh Air, John Powers said that Death Note is "at least as addictive as a show like Lost". It was also listed as the 51st best animated show in IGN's Top 100 Animated Series. Hyper wrote: "Running over thirty-seven 20 minutes episodes, the anime sticks much closer to the manga so takes a far more languid approach to storytelling, better fleshing out the fantastic characters of Light and his nemesis, L. Light in particular is one of the most layered characters to appear in anime in a long time." Jacob Hope Chapman from Anime News Network praised Teru Mikami's role as bloody and flashy as ever better than that of Near, Mello, and Misa.

Light novels
A.E. Sparrow of IGN reviewed the novel Another Note and gave it a 9.5 out of 10. Sparrow said that the author understood "what made these characters click so well" and "captures everything that made the manga the compelling read that it is". Sparrow said that fans of Death Note who read Another Note will "find a welcome home" in Nisio Isin's work which "adds a few more fun layers" to the Death Note franchise. The novelization of L: Change the World became the second top-selling light novel in Japan during 2008.

Legacy and controversies
The series release outside Japan has inspired other works, as well as individuals making their own mock "Death Notes", including one that was associated with a real-life murder. According to Wired magazine, Death Note "[turned] Japan's most-popular print medium into an internationally controversial topic that has parents wondering whether they should prohibit their kids from reading manga entirely". Live-action director Shusuke Kaneko commented in response, "If preventing them from seeing this movie is going to make kids better, then why not prevent them from watching all bad news?".

In regards to the 2019 The Twilight Zone episode "The Comedian", Rosie Knight of The Hollywood Reporter stated that "Samir's story appears to take a large influence from ... Death Note." The Simpsons has parodied Death Note in both comic books and animation with the 2008 comic book story "Murder, He Wrote" in The Simpsons Treehouse of Horror #14, where Bart receives the notebook from the Ryuk-ified ghost of Krusty the Clown, and the "Death Tome" segment of the 2022 television episode "Treehouse of Horror XXXIII", with Lisa receiving the titular book.

Bans and attempted bans
Early in 2005, school officials in Shenyang, the capital of Liaoning (People's Republic of China), banned Death Note. The immediate cause was that students had been altering notebooks to resemble Death Notes and then writing the names of acquaintances, enemies, and teachers in the books. The ban was designed to protect the "physical and mental health" of students from horror material that "misleads innocent children and distorts their mind and spirit". Jonathan Clements has suggested that the Chinese authorities acted partly against "superstition", but also against illegal, pirate publishers of Death Note. The ban has been extended to other Chinese cities including Beijing, Shanghai and Lanzhou in Gansu Province. Legally published Chinese-language versions of Death Note are published in Hong Kong. On June 12, 2015, the Chinese Ministry of Culture listed Death Note among 38 anime and manga titles banned in China.

In 2007, the education bureau in Pingtung County, Taiwan asked teachers to pay attention to any negative influence on elementary school students reading the manga. In May 2010, the Albuquerque Public Schools in New Mexico held a hearing to ban the Death Note manga from their district's schools; it was unanimously voted down. After volumes of Death Note were found at the February 2013 suicide of a 15-year-old girl in Yekaterinburg, Russia, a local parents' group began campaigning to regulate all media based on the series, saying that it had an adverse effect on the minds of children. In March 2014, investigators concluded that the manga did not cause the girl to commit suicide.

Imitations of the series
There have been various imitations around the world of the premise of Death Note. At least one instance was linked to a crime - on September 28, 2007, two notes written with Latin characters stating "Watashi wa Kira dess" [sic], a mis-transliteration of "I am Kira" (私はキラです), were found near the partial remains of a Caucasian male in Belgium. The case has been called the "Mangamoord" (Dutch for Manga Murder) in Belgian media. It was not until 2010 that four people were arrested in connection to the murder. A senior at the Franklin Military Academy in Richmond, Virginia, United States was suspended in 2007 after being caught possessing a replica "Death Note" notebook with the names of fellow students. The school's principal wrote a letter to the student's parents linking to an unofficial website where visitors can write names and circumstances of death for people they want to die.

In South Carolina in March 2008, school officials seized a "Death Note" notebook from a Hartsville Middle School student. District officials linked the notebook to the anime/manga. The notebook listed seven students' names. The school planned a disciplinary hearing and contacted the seven students' parents. In Gadsden, Alabama in April 2008, two sixth-grade boys were arrested for possession of a "Death Note" that listed names of several staff members and fellow students. According to Etowah County Sheriff's Department Sgt. Lanny Handy, the notebook was discovered the previous afternoon by a staffer. The students were suspended from the county's schools, pending a juvenile court hearing. The students, their parents, and school officials had met with Handy and a junior probation officer. In Gig Harbor, Washington, one middle school student was expelled and three were suspended on May 14, 2008, for having 50 names in their own "Death Note" book, including President George W. Bush.

It was reported in September 2009, that a Year Eight boy in Sydney, Australia, created a "Death Note" that along with names contained a "battle plan" detailing where bombs could be placed inside his school. In December 2009, two students at an elementary school in Oklahoma were disciplined for a "Death Note" with the names and descriptions of deaths of two girls that had angered them. A Michigan middle school student was suspended indefinitely in March 2010 for a "Death Note". In May 2010, a middle school student in Avonworth School District in Pennsylvania was suspended for a "Death Note" with names of fellow students and pop singer Justin Bieber. In February 2015, a fifth-grade student of an elementary school near Pittsburgh was suspended for owning a "Death Note" and writing other students' names in it.
