Ryuk (Death Note)

Shūsuke Kaneko, director of the live-action 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 were an actor "inside a rubber suit."[4]

Digital Frontier, a computer graphics company, animated Ryuk. Kaneko said that because Ryuk's physical structure is "different from a human’s," he thought of an idea of visualizing a person in a Ryuk costume. He also wanted the audience to think of Ryuk as a person in a Ryuk costume talking to Tatsuya Fujiwara, the actor who plays Light. He said that he was "asking for too much" and that he wanted audiences to see the film Ryuk as more than "a product of the latest CG technology." Fujiwara said that due to the constant filming with Ryuk he rarely interacted with other actors during the filming of the first film; The Star of Malaysia describes Fujiwara's emotions as "mock frustration." Fujiwara described the CG Ryuk as "so selfish" and "far more difficult to work with" than a human actor.[5]

The director of the American adaptation, Adam Wingard, wanted to do the opposite of the Japanese films and have an actor on set portraying Ryuk as much as possible. They had seven-foot-tall actor Jason Liles wearing the suit and performing both the mannerisms and dialogue alongside the other actors, but cut out his face and voice and used Willem Dafoe's facial capture and dialogue. "What we did was basically cut out the on-set creature's face and had Jason wear these red LED glasses, so at least we could see a representation of his glowing eyes, knowing we were going to replace that later with some CGI, and then voice it over with Willem." The production initially created a large prototype, animatronic puppet of Ryuk to use, but it was eventually abandoned.[6]

Ryuk is a Shinigami bored with the activities (or lack thereof) of the Shinigami realm, so he decides to obtain a second Death Note and drop it in the human world for someone to find, hoping to relieve his boredom. He succeeds in tricking the Shinigami King out of a second Death Note. He deliberately writes the instructions inside the front cover (in English, which he assumed to be the most popular language in the human realm) so people would understand its purpose.

The Death Note is discovered by Light Yagami, and Ryuk follows him around for much of the series to see how Light uses it. Ryuk has a fairly humanoid appearance. His skin is blueish gray, or a purplish color, his limbs are abnormally long, and he has bulging yellow eyes with black irises (red in the anime); in the films, he is represented by CGI.

Ryuk is characterized by his constant amusement by, and apathy in regards to, Light's problems as well as his interest in humans. He enjoys seeing Light overcome the various challenges put to him, and often waits until the worst possible moment to inform him of a certain aspect of the Death Note just to get a laugh. He is occasionally helpful if it serves his own interests, such as obtaining apples or furthering his own amusement, but for the most part will jokingly ask Light what his next move will be or have Light explain to him the point of a certain action. He tells Light in the first volume he doesn't always look at what Light writes because he finds it more amusing. Light describes Ryuk as a "crazy-looking, supernatural creature with these wicked eyes" who becomes ("surprisingly") a "moral compass" for Light in the film version of Death Note.[7]

Ryuk has a great fondness for apples, comparing their effect on Shinigami to that of cigarettes and alcohol.[8] He claims to go through a type of withdrawal if he goes for too long without them. His withdrawal symptoms involve twisting himself up like a pretzel and doing handstands. He also states that he is shy around girls; when Misa Amane hugs him he becomes intangible. In addition to apples, Ryuk is fond of video games, first shown in the omake eight-panel comic series, where he asks for a Silver Game Boy Advance SP, originally published in Weekly Shonen Jump Volume 4-5 (double issue) in 2005. 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 cameras.[9]

As Ryuk explains when he first meets Light, he is bound to take Light's life when his time comes. In the manga, Ryuk does this after Light is shot several times by Matsuda. He desperately begs Ryuk to write the names of the investigation team and the SPK members in the Death Note, which he first implies he will do, but Ryuk, reminding Light that he is not on anyone's side, just writes 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, he decided it was all over for him. Ryuk returns to the Shinigami realm after Light suffers an agitated death.[10]

Two years later, Ryuk berates another shinigami in their attempt to replicate his success with Light by giving their own Death Note to a "weak" human. A further six years later, Ryuk returns to Earth and gives another human his Death Note, who asks him to return with the Death Note in another two years. Subsequently, in 2019, Ryuk returns and the pair sell the Death Note to the U.S. President for $100 trillion, to be divided evenly amongst every Japanese bank account holder under the age of 60, before the human relinquishes (and memories of) his Death Note to Ryuk. When Ryuk returns to the Shinigami Realm before delivering the Death Note, the Shinigami King, berating him, adds a rule forbidding the sale of Death Notes, causing the U.S. president to reject the Death Note out of fear for his own life and merely tell the world he has it, while the human dies when he accepts his ¥1 billion.[11]

Ryuk in the anime.

In the anime adaptation, Light does not ask for Ryuk's help and manages to escape the warehouse thanks to Teru Mikami's suicide distracting everyone else. However his wounds are too severe for him to escape very far, and Ryuk, who is watching him from atop a pole, decides that following Light around during a prison sentence is not worth his time and thus writes Light's name in his Death Note, remarking that he had a lot of fun with him regardless. Unlike in the manga, Light passed away peacefully, with an apparition of L standing over him - mirroring Light standing over L on his death. Much later, after Ryuk returns to the Shinigami realm, he is asked by a new shinigami to recount his time on Earth as the latter prepares to go there himself, and Ryuk mentions Light as the unnamed shinigami leaves before Ryuk has finished recounting his tale.[12]

In the pilot chapter of Death Note, Ryuk is the master of two Death Notes which he drops 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.[13] Death Note 13: How to Read describes the Ryuk of the pilot chapter as "really lazy" and "incompetent".[14]

In the film series, Ryuk is voiced by Nakamura Shidō. The second film ends in much the same manner as the manga, except Ryuk's silence leads Light to believe that he is willing to help. When Light learns differently, 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.

In the spin-off L: Change the World, Ryuk offers L the Death Note. When L refuses and proceeds to burn it, Ryuk complains that L is boring and disappears, returning to the Shinigami realm.

In the fourth film, Death Note: Light Up the New World, Nakamura Shidō reprises his role as the voice and motion capture of Ryuk.[15] 10 years after the end of Kira case, Ryuk again visits the human world to find the successor of kira on the reaper king's order. He finds Light's biological son Hikari Yagami and gives him a death note. Teru Mikami, his guardian who raised him gets insane and kills him by writing his name in the notebook. The leader of Death Note task force, Tsukuru Mishima witnesses the whole thing and kills Mikami and takes his notebook. Tsukuru becomes the new owner and Ryuk stays with him. Later Tsukuru dispossesses his Death Note and asks Ryuk to give the Death Note and Light's message to the cyberterrorist, Yuki Shien. Ryuk finds his new mate. Later, Yuki is killed in a crossfire and Ryuk is seen for last time talking to Tsukuru explaining why death reapers are looking so hard for the next kira because the death reaper king promised that anyone who finds the next kira would have the throne after he retired. Ryuk also says that they will keep sending death notes until there's a next kira. Ryuk forbades bye and disappears.

In the live-action TV drama, Ryuk is voiced by Jun Fukushima and Daisaku Nishino is the motion capture actor of Ryuk. At the end of the series, Light begs Ryuk's help but Ryuk lets Light burn in the fire. Then he returns to shinigami realm with Rem.

Actor Willem Dafoe provided the voice acting and motion capture of the character's facial elements in the American adaptation. Unlike the source material, Ryuk does not possess multiple Death Notes, and has passed the Death Note to various people throughout the decades, with each one of them using the notebook for different purposes. Despite the film's overall mixed critical reception, Dafoe's performance and characterization of Ryuk has been widely praised by fans and critics alike, with many singling him out as one of the film's main highlights.[16]
