Ryuk

"Because I was bored, that's why."

- Ryuk ("Boredom")

Ryuk (リューク, Ryūku) is a Shinigami who indirectly gives Light Yagami a Death Note. Ryuk is bored with the Shinigami Realm. In an effort to amuse himself, he steals a second Death Note and drops it into the Human World for someone to find. This Death Note is discovered by Light, who uses it in an attempt to rid the world of evil and injustice, satisfying Ryuk's need for entertainment.

Appearance
Ryuk has a fairly humanoid appearance. He is extremely slim and has light gray skin, almost blue-ish in color, with spiky black hair; thin, blue-grey lips; and sharp, pointed teeth. His limbs are abnormally long and he has large, round yellow eyes with bright red irises. He also has retractable feather-like wings on his back that enable him to fly.

Character
Ryuk has a great fondness for apples, stating the addiction to be an equivalent of cigarettes and alcohol for humans. Shinigami Apples are withered and taste like sand, as he shows Misa at one point, which is why he prefers apples from the human world. He suffers certain symptoms of withdrawal if he goes for too long without eating them. His withdrawal symptoms involve twisting himself up like a pretzel and doing handstands.

He also states that he is shy around girls, which is revealed when Misa regains her memories and hugs Ryuk out of excitement in seeing him.

Ryuk is fond of video games, first shown in the omake eight-panel comic series, where he asks Light for a Silver Game Boy Advance SP for Christmas. On another occasion, Ryuk asks Light if he wants to play Mario Golf (changed to "video games" in the anime), but receives no answer since Light's bedroom is bugged with microphones and rigged with cameras.

Ryuk also regards Light as "interesting", specifically during his intelligent experiments and loopholes in regarding the Death Note's rules and instructions. In one instance, Light manages to trick a bus-jacker into touching a piece of paper from the Death Note enabling him to see Ryuk and subsequently making Ray Penber, the undercover police officer who was following him that day, think the bus-jacker was suffering from hallucinations as well as tricking Ray into giving Light his identity. In another instance, Light correctly surmises that if he writes in the cause of death and the circumstances that lead up to it before he writes in the name he can add the name in afterwards and it will still happen, which was something even Ryuk didn't know. This, according to the rules of the Death Note, granted Light a full nineteen days of the human calendar in order to fill in a name. It also allowed Light to bypass the forty seconds time limit rule in regards to the cause of the death as well as the six minutes and forty seconds time limit rule in regards to the details of the death, as these criteria had already been filled in.

Plot
Ryuk deliberately writes the instructions inside the front cover of the Death Note (in English, which he assumed to be the most popular language in the Human World) so people would understand its purpose. The Death Note is discovered by Light, and Ryuk follows him around for much of the series to see how Light uses it.

As Ryuk explains when he first meets Light, he will take Light's life when his time comes. In the manga, Ryuk does this during the final confrontation between the Japanese Task Force and the SPK after Light is shot several times by Matsuda. Light desperately begs Ryuk to write the names of the investigation team and the SPK members in the Death Note. Ryuk appears to write them down, but he reveals he simply wrote Light's name instead. He was expecting Light might have thought of some way out of his situation, but seeing as he was desperate enough to go to Ryuk for help, Ryuk decided it was all over for him. Ryuk returns to the Shinigami Realm after killing Light.

In the anime, Light does not ask for Ryuk's help and manages to escape the Yellowbox Warehouse while Mikami's suicide distracts everyone else. With his wounds too severe for him to escape very far, Ryuk, who is watching him from atop a pole, decides that following Light around during a prison sentence waiting for his death is not worth his time and thus writes Light's name in his Death Note, giving Light the final words, "It's been interesting." Light dies with an apparition of L standing over him, mirroring Light standing over L at his death.

Relight anime films

The Relight films are a condensed version of the anime series. The premise of the films is that Ryuk tells the story to a fellow Shinigami.

Sometime after Light's death and Ryuk's return to the Shinigami Realm, Ryuk becomes popular among other Shinigami about his time spent in the human world with Light. Eventually, Ryuk's story catches the attention of an unnamed Shinigami, who visits Ryuk to hear it.

Live action film series

 * Main articles: Death Note, Death Note: The Last Name, L: Change the WorLd, Death Note: Light Up the NEW World

Ryuk is very similar to his canon self in the film series. The second film ends in much the same manner as the manga, except Ryuk pretends to be more cooperative by not telling Light in advance of his death, and even joins in his laughter over the fact that the task force can't shoot through the incorporeal Ryuk. When Light learns differently after asking Ryuk to show him the Note, Light yells at Ryuk and jumps through him, trying in vain to stop his death before dying in his father's arms; before this, Ryuk takes this opportunity to reveal to Light that humans who have used the Death Note are unable to enter either Heaven or Hell regardless of their actions in life. After Light's death, Ryuk asks L if he's going to use the Death Note, and when L says that he won't, Ryuk moans about L being boring and flies off. Ryuk is last seen several months later, laughing and circling around Tokyo Tower.

In the spin-off midquel L: Change the WorLd, Ryuk encourages L to use the Death Note, trying to tempt him by reminding him that Light used it to become a god. When L asks if Light died like a god, Ryuk struggles to answer, and L proceeds to burn both notebooks, sending Ryuk back to the Shinigami realm.

Ryuk is briefly seen in the third episode of the miniseries Death Note: New Generation. He apparently delivers a notebook directly to Kira-worshiper Yuki Shien, who begins acting as a new Kira. The episode ends with Ryuk laughing and saying, "Interesting."

Ryuk will be returning in the upcoming film Death Note: Light Up the NEW World.

Netflix film
Ryuk will be voiced by American actor Willem Dafoe in an American film adaptation of Death Note.

Manga pilot chapter
In the Death Note manga pilot chapter, Ryuk is the master of two Death Notes that he dropped into the human world; Taro Kagami picks up the first one, and Ryuk talks to Taro. The other is picked up by Taro's classmate, Miura. The police burn Miura's book, not knowing of the existence of the first book. At the end of the chapter Ryuk follows an older Taro. Death Note 13: How to Read describes the Ryuk of the pilot chapter as "really lazy" and "incompetent."

Manga yonkoma

 * Main articles: Death Note 13: How to Read and Yonkoma

Death Note 13: How to Read describes Ryuk in the Death Note yonkoma as, of the characters, one who "may" be the character most resembling the equivalent character in the Death Note series.

Musical
In Death Note: The Musical, Ryuk's role is very similar to canon, although he notably interacts more with Rem.

Ryuk is introduced in the Shinigami Realm, and he goes to Rem complaining that he is bored. Rem is looking down at the humans, and the two of them mock humanity. Ryuk then drops his Death Note into the human realm, which is subsequently picked up by Light Yagami.

Ryuk visits Light after he has begun using the Death Note, celebrating the creation of Kira, which he finds interesting. Ryuk stays by Light's side, such as attending Misa's live performance and seeing Rem again when Misa and Light meet up. When it seems that Rem is getting attached to Misa, Ryuk reminds her not to break the shinigami rule about helping humans. When Misa first meets L and realizes the name she sees doesn't match what he gave her, Ryuk reminds her that she isn't supposed to know that so she doesn't make it obvious.

After Light thinks he's won by defeating L, Ryuk picks up the Death Note, bites his finger to draw blood, and begins to write. Light asks him whose name he's writing, and when Ryuk says it's Light's name, Light panics and desperately tries to get Ryuk to stop. Ryuk is unmoved, having grown bored of the human world, and Light dies of a heart attack. Ryuk roles Light's dead body over, pulls an apple out of Light's jacket, and takes a bite.

Ryuk performs the following songs in the musical:
 * They're Only Human is a song Ryuk and Rem sing about humanity.
 * Kira is a solo song Ryuk sings when he first meets Light.
 * A Cruel Dream Reprise is a song Ryuk and Rem sing as Rem becomes more emotionally attached to Misa.

Ryuk is portrayed by various actors for the different musical productions:

Conception
Tsugumi Ohba said that he always mentioned Apples in the thumbnails because he wished to use "the dying message that Shinigami only eat Apples." Therefore, he simply needed Ryuk to hold Apples and that "there's no other reason." Ohba also said that he specifically chose Apples because the red "goes well" with Ryuk's black body and that the apples "fit well" with Ryuk's "big" mouth. When Takeshi Obata informed Ohba that Apples held religious and psychological significance and that a person could "read a lot" into their inclusion and its symbolism. When he assumed that was the reason why Ohba included the apples, Ohba said that he did not "think about that at all" and that he merely believes that "apples are cool... that's it. (laughs)" Ohba added that he felt including aspects that could become later plot points was beneficial, and the apples were used as a point when Light asked Ryuk to search for the cameras in exchange for apples.

Obata said that he encountered difficulty in creating Ryuk. He said that his original idea of Ryuk consisted of Ryuk looking like a "young man similar to Light" with black hair and wings. Obata said that he had the idea of Shinigami looking like "attractive rock stars." Obata felt that if Ryuk appeared to be more attractive than Light he would "appear to be the main character" and "things wouldn't work as well." Obata said that he decided to erase the previous design and use the final design when his editor told him that Ryuk did not have to appear to be human. Obata said that he liked the "monster-like" appearance and added that, with his face, "you can never really tell what he is thinking." Obata said that he encountered difficulty while drawing Ryuk in the pilot chapter since he did not "have a good handle" on the "bone structure of his face." Obata said that during serialization he became "so used" to the underlying structure that he could visualize it. Obata describes Ryuk's face as appearing different between the pilot chapter and the actual Death Note series. In How to Read 13 Obata thought of an idea involving Ryuk's face being a mask, and under the mask would be an "attractive" face.

When designing Ryuk's Death Note, Obata thought about the appearance of Ryuk's handwriting. Ryuk wrote the words "Death Note" on the cover of his own notebook, and when he took possession of Sidoh's book he wrote the same words on the front cover.

Conception of Ryuk in the films
Shūsuke Kaneko, director of the films, said that he chose to create Ryuk with computer graphics as it would make the aspect of Ryuk only appearing to people who have touched the Death Note "believable" and that the audience could "tell instinctually" that Ryuk is a shinigami with "no real presence." Kaneko added that if a human actor represented Ryuk, the appearance would have been "too realistic," the actor may have impacted Ryuk's "presence," and the audience may have "doubted he was a death god, if only for a second." Kaneko ordered the graphics team to design the graphics as if it was an actor "inside a rubber suit."

Reception
Tom S. Pepirium of IGN said that "Brian Drummond IS Ryuk." Pepirium described Drummond's voice as "excellent" and that this makes it "hilarious" to watch "Ryuk and his never-ending grin giggle at the events he put into motion."

Kitty Sensei of OtakuZone had her opinions of the film portrayal of Ryuk published in The Star, a Malaysian newspaper. In it Kitty Sensei said that Ryuk "looks a little artificial in the beginning." but she eventually became used to the portrayal and loved "Ryuk's gleeful chuckles and fish-faced grins."

The sfist describes Ryuk as the sole "(potential) cheeseball factor" of the first film and that he may be "difficult to get used to"; the article stated that Ryuk "adds" to the film if the viewers "let go enough to accept Ryuk's presence."
