L Lawliet and Light Yagami

Ryuk has a fairly humanoid appearance. He is very thin, with light gray skin, almost blue, spiky black hair, thin gray-blue lips, and sharp teeth. His limbs are abnormally long, and he wears rings on his fingers. He has large, round yellow eyes with bright red irises and wings on his back that he can retract. Light Yagami, the owner of the Death Note, is the best death god he's ever seen, as Ryuk once remarked. The shinigami enjoyed watching Light Yagami's activities; he never interfered with him or helped him write names in the Death Note. Although he would sometimes provoke him for fun. This god's ethos is one of entertainment; he doesn't care what happens in the human world, as long as it's interesting and fun. Often, he informs Light about certain aspects of the Death Note at the very last minute; it's interesting to see how he handles things. Although he sometimes helped Yagami for his own interests, apples are his weakness. Ryuk, like a human, succumbed to weaknesses... entertainment, apples. He has a rather unique, inhuman appearance. Ryuk is a shinigami, and in the world of the Death Gods, he is considered quite handsome. He wears tight-fitting black leather clothing, the collar and sleeves of which are trimmed with the fur of an unknown beast from the Underworld. He has a weakness for various skulls, crosses, and iron chains. On his belt, you can see a special decoration for the Death Note in the form of crosses. This is why Ryuk always carries the note with him. He adores massive rings. A silver earring with a heart at the end can be seen in his left ear. His face is certainly the most beautiful, but his large, bulging eyes, white skin, and unusual hairstyle terrify anyone. Ryuk also has black wings, which he uses for flight. But only those who touched his Death Note can see all this; everyone else usually sees only the apples gradually disappearing into thin air. Ryuk also dislikes boredom and will do anything to amuse himself.

The Death Note is an item used by Death Gods to extend their lives. The note will become part of the real world once it touches the ground. If a Death God doesn't pick up the note before a person does, the note will become their property until they die or give it up. A person can also give the note to anyone else, but then the Death God erases their memories of the note and the events surrounding its ownership. The Death Note contains numerous rules that are open to interpretation: Death Gods, who use the note only to extend their lives, are unaware of some of its capabilities. (The rules below are written by Ryuk as a guide.)

Main rules edit The person whose name is written in the Death Note will die. The notebook will not work if the person writing the name doesn't know the face of the person who is to die. Therefore, people with the same name are safe. If the cause of death is written within 40 seconds of the name being written, then that is what will happen. If no cause of death is specified, the specified person will die of a heart attack in 40 seconds. After writing the cause of death, there are another 6 minutes and 40 seconds (400 seconds in total) to write the circumstances of death. Note: In Japan, the number 4 is considered unlucky and associated with death due to its similarity to the word "shi" meaning "death."

Light has medium-length brown hair with bangs and hazel eyes. Other distinctive features of Yagami include his chiseled features, flawless white skin, and an infectious, charismatic smile. He is always neatly dressed. Light prefers formal and understated clothing, emphasizing his discipline. Light is presented as a teenager with exceptional intellectual abilities, calculating and cunning. However, after receiving the notebook, Light Yagami decided to become God and create a new world without criminals. He partially succeeded, but he did not realize that by killing other criminals, he himself became one. He is moderately sociable, but does not have permanent friends or girlfriends. He is uninterested in the activities of his peers, constantly remaining alone with his hobbies. Since childhood, Light hated crime and was guided by a sense of justice in his actions, but did not show himself unnecessarily.

Yagami possesses a sharp, tenacious mind and analytical thinking. He is skilled at cunning, lying, and manipulation, often using people as puppets because he sees no one as his equal.

On the surface, Yagami appears emotionless and calm. In reality, he suffers from delusions of grandeur, hypocrisy, sudden emotional outbursts, and manifest psychoses. By nature, he is cruel, apathetic, and adventurous. Under the influence of emotions and psychological problems, he makes serious mistakes, creates dangerous situations, and fails to understand the consequences of his actions.

However, despite all his crimes, Light will never become the embodiment of pure evil. He sincerely loves his father and sister (he didn't care when his father died, so this is debatable) and will never stop caring for them. Thus, humanity and compassion will forever remain within him.

L is a young man with a slim build, pale skin, tousled, long black hair, and dark eyes. One of his most noticeable features is the bags under his eyes, a result of lack of sleep. He wears blue jeans and a white long-sleeved shirt. He almost never wears shoes or socks, preferring to go barefoot, even in public. He showed up at Light Yagami's school barefoot and sat on a bench, not even bothering to put on shoes before going on stage. L is quite secretive and communicates with the outside world only through his assistant, Watari. He never shows his face to the outside world, using only the capital letter L. After meeting with the Japanese task force, he asks them to call him "Ryuzaki or Ryuga" as an additional security measure. None of the task force members ever learned his real name, and it's never properly revealed in either the manga or anime. Many doubt his powers of deduction, given his disheveled and listless appearance, but in reality, L possesses a remarkable intellect. L is prone to doubting everything he sees and is extremely meticulous and analytical. He's adept at deceiving his opponents and is willing to go to extreme lengths to solve a case. Some of his tactics are quite drastic, such as sending death row inmate Lind L. Taylor as himself to lure out Kira, while others seem bizarre, such as handcuffing himself to a suspect, Light Yagami. He also has a dry sense of humor and isn't above making sarcastic remarks. Although he's generally polite to some, Al can sometimes seem condescending. As you might have noticed, Al has quite a few quirks (presumably traits of Asperger's syndrome). For example, he prefers to sit with his legs crossed, even on chairs and armchairs. However, there's an explanation for this. He claims that sitting normally reduces his judgment by 40%. He enjoys sweets and unusual food combinations.
