Shinigami Eyes

Shinigami Eyes are eyes which can see both the names and lifespans of Humans floating above their heads. If a Shinigami drops its Death Note on the human world and a human picks it up, that Shinigami can give the human Shinigami Eyes at the expense of taking half of that human's remaining lifespan.

Humans who follow through with the "eye deal" gain the ability to see other humans' names and lifespan, although just as Shinigami can't see each other's lifespans, cannot see their own lifespan or the remaining lifespans of other Death Note users. They also gain 3.6 times their current vision, as revealed by Tsugumi Ohba in Death Note: How To Read 13. The eye deal is first mentioned by Ryuk when he offers Light the trade, which Light refuses, as he is unwilling to give up half his lifespan.

In the manga, Shinigami Eyes are depicted as having gold irises, with red pupils and pale yellow sclera. In the anime, the irises are simply a bright and shining red; in the films, they are depicted with a yellow "cat eye" appearance. It should be understood that this is merely the representation of a person having Shinigami Eyes for the reader/viewer's benefit, as it is impossible for humans to tell (scientifically or otherwise) who possesses Shinigami Eyes.

In Death Note: Another Note, the antagonist Beyond Birthday (a former Wammy's student and would-be successor to L) is said to have been born with Shinigami Eyes, enabling him to see the names and lifespans of those around him. It is never explained how a human could be born with the eyes, though the idea of a Shinigami losing his or her eyeball and then dropping it to Earth was mentioned in the story.

Misa Amane briefly explains to Light that in order for the eyes to work, the person being looked at must be visually recognizable. The eyes will not work if the person's face is obscured or out of view, even partially. Also, apparel (such as glasses) have no effect and do not prevent the name from being shown.

A person's name can be seen in a photograph or even video footage, yet it is impossible to tell a person's name from a drawing (no matter how photorealistic it appears). If the person is deceased, their name will not appear in a photograph or in video footage of them.

Misa Amane
Main article: Misa Amane

In all incarnations of the franchise, Misa Amane is the first character to be depicted as having made the trade. After she is arrested on suspicion of being the Second Kira, Rem erases her memories of the Death Note, refusing to kill her, only wanting the best for her. With her memories of the Death Note gone, Misa loses her Shinigami Eyes in the process. After regaining her memories and uncovering the buried Death Note that Light left in the woods, she makes a second eye deal with Ryuk, cutting her life span in half again.

After the timeskip, Misa continues to use the power of the eyes up until Light orders her to forfeit her Death Note and pass it on to Teru Mikami, causing her to lose her memories and the Shinigami Eyes once more. It can be assumed that after Rem's death, Misa regained a portion of her lost lifespan, though the question of how many years she had left remaining is unknown, as Death Note: How To Read 13 reveals that Misa committed suicide a year after Light's death (this is also implied in the anime).

In the films however, she does not commit suicide and only loses her memories of the Death Note (and the eyes) after Light's death and L burns the notebooks. She is shown a year later, wondering why there seems to be a gap in her life and memories.

Kyosuke Higuchi

In the manga and anime, Higuchi (as the Third Kira) gains the Shinigami Eyes after making the deal with Rem during the car chase. However, his time with the eyes is short-lived, as he winds up captured and dies shortly after, Light having written his name down on a piece of the Death Note.

Kiyomi Takada (film)

In the second film Death Note: The Last Name, the Yotsuba story arc is removed, with Sakura TV and Kiyomi Takada serving in place of The Yotsuba Group and Higuchi, respectively. Takada gains the Shinigami Eyes from Rem, but as in the case of Higuchi, winds up captured as Kira and killed by Light's piece of Death Note.

Kal Snydar (a.k.a. Jack Neylon)
Main article: Kal Snydar

In the manga, after Sidoh discovers the Mafia hideout, a subordinate of Mello known as Jack Neylon (real name Kal Snydar) is made to go through with the eye deal. In the first failed raid on the hideout, Jack reads out the names of the names of the Special Ops team as Sidoh unmasks each of the members. Each person's name was then written down by Rod Ross in the Death Note. Neylon/Snydar later dies during the second raid, as Light had written his name down in the Death Note, along with other Mafia members. In the anime, the eye deal and the first raid of Mello's hideout were left out entirely.

Soichiro Yagami
Main article: Soichiro Yagami

In both the manga and the anime, Light's father ends up being manipulated into trading for the eyes as part of Light's plan to infiltrate Mello's hideout the second time. Interestingly, Matsuda was the original intended target, but Soichiro accepts instead. With the power of the eyes, he is able to see Mello's true name (Mihael Keehl) but is shot by one of the few remaining Mafia members and is fatally wounded when Mello detonates charges and destroys his hideout. Light desperately tries to persuade his dying father into writing down Mello's name in the Death Note, but Soichiro succumbs to his wounds. He then dies, relieved by the belief that his son isn't Kira, as Light's lifespan was visible at the time.

In the films, Soichiro never gets the eyes and doesn't die, as there is no timeskip or the events of "part 2". Unlike his manga/anime counterpart, however, he does learn that his son is Kira.

Teru Mikami
Main article: Teru Mikami

After gaining Misa's Death Note, Mikami is revealed to have made the deal with Ryuk in order to kill the members of Sakura TV's "Kira's Kingdom", one of them being Demegawa. He remains with "the eyes" all the way up to his death.

Beyond Birthday
Main article: Beyond Birthday

Beyond Birthday was born with Shinigami Eyes. He is the killer in the BB murder cases discussed in Death Note: Another Note.

C-Kira
Main article: C-Kira

C-Kira ("Cheap Kira"), true identity unknown, is the catalyst of the post-series one-shot, where he/she kills off the elderly and sick, as well as people who wish to die. Though his/her identity is never revealed, he/she is depicted with Shinigami Eyes, presumably having made a lifespan trade with Midora. C-Kira commits suicide at the end of the one-shot manga when Near calls him an "abominable murderer" after announcing that he has no interest in the case. Near, like L before him, will only accept cases that he takes a personal interest in.
