Kagerou Daze/Eye Abilities

Eye Abilities (目の能力 Me no Nōryoku) are powers derived from Azami's snakes, which are the physical manifestations of her wishes. Each snake's set of abilities is based on the wish that created them. After Azami gave the Snake of Combining Eyes to Marry, the snakes began to leave the Kagerou Daze by joining with deceased humans who entered it and have similar wishes to those that created them. This, in turn, gives these humans a surrogate life to return to the real world with and the snake's Eye Ability. Generally, those with eye abilities initially do not have much control over their Eye Abilities and can only perform its basic function, but they can train themselves to control and further use their powers. When the abilities are activated, the users' eyes turn red and can become similar to those of a snake. In the manga, the abilities are illustrated by a gradient screentone over their users' eyes to counter the monochrome color palette.

Tsubomi Kido

 * Kido can use Concealing Eyes to divert attention away from herself, people, and objects within two meters of herself at standard usage, making it seem as if they are invisible.   Physical contact, however, can break the effect.   Furthermore, it is weak against people who are familiar with the person(s) and/or objects that are being concealed, such as Shintaro to his sister, Momo,  or the Snake of Clearing Eyes to the Mekakushi Dan. When she was younger, she had trouble controlling her ability and parts of herself would "disappear" when she was upset.  She feared that she would ultimately disappear and be lost forever. She has since practiced to control her ability and can even use it to suppress Momo's Drawing Eyes.  Kido can also vary the intensity and preciseness with which she hides herself or others, as she can make herself invisible even to others already being hidden with her ability and can hide herself while only partially suppressing Momo. When using her ability at full strength, she can apply it to outside of a two-meter radius, especially when the objects are interconnected, like a building. Kido's ability also allows her to conceal her own memories, though she does this only with Azami's guidance in the Kagerou Daze and forgot about this specific power. Concealing Eyes can also affect virtual objects, such as Takane's crosshairs and/or the pig enemies in the Headphone Actor game.  When using her eye ability on a chatroom in Mekakucity Talkers, she can make parts of her messages appear deleted on the spot.

Azami

 * Azami could use Concealing Eyes to not only fade herself and others out of notice, but to also "conceal" someone's senses from themselves. She could do this to such an extent that the targeted person would no be longer capable of recognizing sound, light or even their own heartbeat. In the Novel Route, Kano speculates that, when used alongside a strengthened Combining Eyes, Concealing Eyes could make it impossible for all people in the world to recognize anything in the world.

Marry Kozakura

 * In both the Novel Route and Manga Route 2, Marry gains the Snake of Concealing Eyes and is able to use its abilities to their full extent with Combining Eyes. She, just like Kido and her grandmother, uses it to conceal herself and others. In Manga Route 2, she uses it to conceal her target's senses from everything but herself, making them perceive the world around them as a white void.

=== Stealing Eyes (目を盗む Me wo Nusumu) ===

Kousuke Seto

 * Seto's ability allows him to read information from his target's mind.   He can also understand animals with his eye ability, though they cannot necessarily understand him. When using his ability at full strength, he can read people's true feelings and memories,  even from past Routes. Before he met Marry, Seto would have trouble controlling the activation, intensity and radius of his eye ability. He would sometimes be able to read the thoughts and emotions of everyone in the entire city, and even now he is still susceptible to losing control of his ability occasionally, such as when he experiences intense psychological distress. One earlier incident caused him to run away to the forest, where he meets Marry for the first time. Since learning how to control his ability, he has expressed disliking using it on humans and will only do so when necessary.  In Mekakucity Actors, he uses Stealing Eyes on Shintaro during the terrorist mall incident to confirm his plan with Kano, and, later, he reads Kano's memories of his past with the Snake of Clearing Eyes and Ayano to understand his situation.  In Mekakucity Talkers, he can use this ability to vaguely "read" others' thoughts regarding certain messages in the chatroom.

Azami

 * Azami could use Stealing Eyes to read the minds and thoughts of animals, humans, and even plants. However, even she did not have full control of this ability and sometimes activated it without intending to. In the Anime Route, she uses this ability to read a person's specific memories to find out what happened to her missing husband.

Shuuya Kano

 * Kano's ability allows him to change how others perceive him and control how he looks, sounds, and even feels to others. He can only apply Deceiving Eyes onto himself and not onto other people or objects. To use Deceiving Eyes to impersonate someone or something else, he needs to know as much as about it as possible, including appearance, sound, and even smell. Pain usually nullifies his ability because it is how he is able to identify himself, but that can fail if he is under extreme psychological distress. Kano learned how to control his ability relatively early compared to his other two adopted siblings.  Kano can make himself seem like an animal, such as a cat, to the point of even simulating the feeling of its fur, but he is unable to truly transform his physical characteristics and has so far failed to be able to make himself perceived as inanimate objects like soumen or Australia. When using his eye ability on a chatroom in Mekakucity Talkers, he can "edit" parts of his messages on the spot.

Azami

 * Azami could use Deceiving Eyes to temporarily change how others perceived her. In the Anime Route, she uses this ability to appear as a giant snake. In the Novel Route, Kano speculates that, when used alongside a strengthened Combining Eyes, Deceiving Eyes could be used to create illusions that extend far beyond their user, with enough reach to affect all people in the world.

Marry Kozakura

 * Marry gains this ability in both Manga Route 2 and the Novel Route. In the Novel Route, she uses it to hide the changes in her appearance caused by a strengthened Combining Eyes.

Azami

 * Azami's ability allows her to turn people who look at her eyes into stone. She can do this to multiple targets at once when using it with Drawing Eyes.

Shion Kozakura

 * Shion's ability also allows her to turn a target into stone. However, using her ability causes much strain to her body, and one use is enough to make her cough blood and collapse.

Marry Kozakura

 * Marry's ability is not as complete as her mother's or grandmother's power, as she is not able to turn people into stone, but instead she can temporarily paralyze others when they meet her gaze.   This ability can also affect virtual objects, as she used it to paralyze enemies and attain a perfect score at the Headphone Actor game. When using this ability alongside a strengthened Combining Eyes, Marry is able to fully petrify her target without repercussions, just like Azami. In Mekakucity Talkers, she projects Locking Eyes' effect through the group chatroom, which causes everyone's messages to send unfinished as they are temporarily paralyzed in real life.

Marry Kozakura

 * Marry's Combining Eyes comes from what was originally Azami's "Queen Snake" and has many powerful abilities. Some of these abilities are automatic; for example, Combining Eyes naturally draws the other snakes and their owners towards Marry, which is what causes the Mekakushi Dan to meet in every Route.   It automatically makes Marry absorb a snake if its owner has died,   although she can also do this to any nearby living snake owner at her own will, and it becomes stronger with each snake absorbed.  A strengthened Combining Eyes alters her appearance, causing scales to appear on her cheeks and arms, shortening her hair with long, white snake-like projections below it and giving her red eyes with prominent snake-like pupils. Details of this appearance change across different medias.
 * Combining Eyes has reality-affecting abilities that grow stronger with the more snakes Marry has in her possession. With two snakes, she can open a portal to the Kagerou Daze, although even with more snakes she may struggle to do so. With around five snakes, she can take control of the Kagerou Daze and change its nature, such as undoing Azami's command to only allow those on the brink of death to enter it,  and with more she can rewind the world back to its beginning.   Rewinding the world is the result of Marry's despair over the "Tragedy", which is when the Snake of Clearing Eyes attacks and kills her friends and what makes her wish to have one more chance to see them again.    This is how she instinctively uses Combining Eyes in Routes where she does not learn how to rationally use its abilities.
 * As its name suggests, Combining Eyes allows Marry to "combine" and simultaneously use multiple eye abilities. In Manga Route 2, Novel Route and Mekakucity Actors, Marry learns how to better control Combining Eyes to use, combine the abilities of any snake that she has absorbed and control the Kagerou Daze through memories that Ayano sends to her with Favoring Eyes. In Manga Route 2 and the Novel Route, Ayano sends her Azami's memories, while in Mekakucity Actors it is unclear whether she sends Marry Azami's memories, Shintaro's memories from previous Routes, or both. Marry can directly command and subjugate other eye abilities, an ability which manifests in the form of black, whip-like bindings. Simply by expressing intense emotions in this state, Marry can generate enough pressure to shatter windows. Combining Eyes also allows her to create new snakes based on her strong emotions and wishes; in Manga Route 2, she uses her wish to "never forget the Tragedy" to turn Ayano into the Snake of Retaining Eyes. Whether that was only possible because Ayano was already living a surrogate life thanks to Favoring Eyes or not is unknown.

Azami

 * Azami used this ability to keep her snakes and their abilities under control and at full force, allowing her to use them without being overpowered by their instinctive desire to grant wishes, although if a wish a snake seeks to grant is too strong, Combining Eyes might be unable to control it. She used this power to combine all of her other abilities in order to create the Kagerou Daze.    Combining Eyes was required for Azami to be able of controlling the Kagerou Daze,  but to change its nature she would need at least half of her snakes with her. Unconsciously, the Snake of Combining Eyes was initially used to create the real world around Azami to create a place where she could fulfill her first wish to understand herself.

Momo Kisaragi

 * Momo's ability can draw people's attention to her regardless of their preferences.   Before meeting the Mekakushi Dan, she had difficulty controlling her ability, which she didn't know existed, and would draw large crowds from people even several blocks away to her and even her home.    At full strength, it affects up to tens of thousands of people, as seen by her newly popular idol status.  She can also use Drawing Eyes to sense where people's attention is drawn to, whether it be on her or on something else.  In the terrorist incident, she uses Drawing Eyes to guide people's attention to Marry's gaze, whose Locking Eyes then temporarily paralyzes the terrorists and hostages.   In the Novel Route and Mekakucity Actors, she uses Drawing Eyes to draw crowds of people to the Snake of Clearing Eyes' building.  In the aforementioned scene and in both the Music and Novel Route versions of Otsukimi Recital, she also uses Drawing Eyes to show Hibiya, who is depressed over losing Hiyori to the Kagerou Daze, her determination and belief in him.   That scene also showcases that Momo can use Drawing Eyes to turn on light sources by attracting light itself.  In Mekakucity Talkers, it has been shown that Momo can also use Drawing Eyes to make people drawn to things besides herself, such as text messages and webpages, and that she can regulate the degree of drawn attention.

Azami

 * Azami could use this ability to such an extent that her targets lost focus of anything besides her entirely, making them drop anything they might be holding and fall to their knees. She used this ability along with Focusing Eyes to find the "least noticed place in the world" in an attempt to escape from humans for good.

Marry Kozakura

 * Marry gains this ability in the Novel and Manga Routes, which she can use it to draw someone's attention and make them lose complete focus on their surroundings.

Takane Enomoto

 * Takane's ability allows her to split her consciousness from her body and take it wherever she wants to. She cannot manifest her spirit-self "Ene" in the real world; instead, it becomes a cyber-being that resides in and can possess electronic devices,   In this state, Takane can navigate through the internet as if it was an alternate world.   She has been shown to be able of hacking computer systems in several occasions,   extracting information from them at will, travelling through e-mail, deleting files, activating alarms,  taking voice samples and using them to impersonate others and to track GPS signals. Her activity in electronic devices greatly consumes their battery. While using this power, her body loses consciousness, and while she does not feel hunger or sleep, her body still requires nourishment, so it can die if not taken care of. Takane can die if the vessel in which her spirit-self currently resides at is destroyed.  It has been implied that being "deleted" can also kill her, however, if she is deleted from a device with an intact connection to the internet, she can simply come back as if nothing had happened. Therefore, the details involved in killing her by "deletion" are unknown. She can use her ability to send chatroom and presumably all digital messages as fast as her own thoughts.

Azami

 * While she was in the real world, Azami did not need to eat or sleep to survive, likely thanks to this ability. When she was unable to move her physical form in the Kagerou Daze, Azami used this ability to manifest her spirit-self and stay "alive" there. When she gave it to Takane, Azami lost her spirit.

Marry Kozakura

 * Marry gained this ability in both Manga Route 2 and the Novel Route. In the Manga Route, she uses the ability to project her spirit into an empty Mekakushi Dan hideout and make it appear standing over a fallen TV screen. Her projected spirit can even use her other eye abilities as if she were physically at the scene itself. Unlike Takane, she does not seem to lose consciousness while using Opening Eyes. In the Novel Route, she uses it to turn into a cyber-being like Ene.

Hibiya Amamiya

 * Hibiya gains the Snake of Focusing Eyes in most Routes and can use the eye ability to perceive objects, locations, and people from any distance and at an aerial view. If he looks at an object, he can see a vision of its owner, but it will not work if that person is in his direct field of vision. He has been shown requiring a lot of effort and concentration to use his ability, though this may be because he gains his ability the most recently out of all the Dan members. Using it for prolonged periods of time exhausts him. In the Novel Route, it is shown that, with practice, he can recall all kinds of visual and spatial information about his target, as long as he has an image of it in his mind, such as how he managed to obtain entire floor plans of the Snake of Clearing Eyes' hideout, down to the last detail, simply by looking at a picture of Kenjirou. In that same scene, he could spot approaching goons of the Snake of Clearing Eyes before Shintaro's group saw them in person. Later, he develops Focusing Eyes to work over phone waves. This allows him to use Momo's phone to locate and connect directly to Shintaro's phone in the Kagerou Daze and speak with him and the others there.

Hiyori Asahina

 * In Manga Route 2, Hiyori gains the Snake of Focusing Eyes and can use its abilities to find anything that she focuses her mind on. However, she is unable to find a specific target if they change their appearance. When the Snake of Clearing Eyes attacks the Mekakushi Dan hideout, she uses Focusing Eyes to watch there from afar and learn its new appearance. Afterwards, she is able to tell whenever it is approaching, down to estimated arrival time based on its moving speed and distance from the group.

Azami

 * Azami could use this ability to find things and places from an aerial point of view. She only had to use a description of something to find it. For example, she used Focusing Eyes and Drawing Eyes to find "the least noticed place in the world". Azami boasted that, even if someone "ran to the ends of the Earth" to hide themselves, she could find them instantly, likely thanks to this ability. She could also use Focusing Eyes to watch the real world from the Kagerou Daze.

=== Awakening Eyes (目を醒ます Me wo Samasu) ===

Konoha

 * Konoha's ability gives him the power to remake his body into one that its true owner, Haruka, finds "ideal". Haruka expected to die young from his hereditary illness, so his ideal body was healthy and supernaturally strong to be able to "make friends" with.  However, Haruka rejected the body, which looked like his video game avatar, and his body in turn rejected him because of his "meager" "spirit", so the Snake of Awakening Eyes assumed control of his body instead, leaving Haruka trapped in the Daze.   Konoha has enormous fighting prowess  and is strong enough to break the floor and ceiling above Kenjrou's lab with just his fist in Mekakucity Actors, which requires 0.3 to 1 Ton of force to be accomplished. He can reach over hundreds of meters in the air with a single jump, and also leap horizontally by that much. He is also very resistant, being able to break inside a building through a window without a single scratch while perfectly shielding Hiyori. In Mekakucity Talkers, Momo claims that Konoha is faster than a bullet train, which is roughly 320 km/hour (199 miles/hour). In the tweets accompanying the Seek at Mekakucity event, Konoha swam from Japan to another country (apparently an European one) in just 40 minutes. In the Novel Route, Konoha is able to heal from a fatal injury with this ability, which appears as multiple black snakes wrapping around his body.

Haruka Kokonose

 * Despite being deprived of his body while in the Daze, Haruka still maintains a connection with it, which allows him to be aware of everything that Konoha hears and sees. This extends to what Konoha experiences both outside and inside the Kagerou Daze. However, whenever the Snake of Clearing Eyes takes over his body, Haruka's connection with it is severed. In the novels, it is said that Haruka's spirit is too weak to handle a supernaturally strong body like Konoha's, which is possibly why, when he retrieves his body in Mekakucity Actors, he remakes it into one that makes him sometimes need a wheelchair. This new body features a changed hair color and the change to Haruka's birthmark that occured back when his body was turned into Konoha.

Azami

 * Azami could use Awakening Eyes to remake her body at will. When in use, it would appear as a mass of black snakes that completely surrounds her before revealing her new form. She could use this ability to heal from several fatal gunshots and presumably other otherwise lethal wounds. She first used this ability to create her body from scratch, having changed her form several times before sticking to the humanoid appearance she is known for. She maintained that form as her primary one despite finding it fragile and inconvenient for locomotion, and it is unknown if she could have drastically changed her form from it anymore. When this ability went to Haruka, Azami lost her body.

Snake of Clearing Eyes

 * The Snake of Clearing Eyes forcefully suppresses Konoha's conscience when possessing him,  although Konoha can sometimes resist its influence, even if temporarily.  It uses Awakening Eyes' appearance-altering abilities to change Konoha's color scheme to a black, gray and yellow one upon possession, and it can skillfully use Konoha's superhuman strength and speed. , such as when it causes a landslide with a single kick. In the Novel Route, it uses Awakening Eyes to rebuild its body molecule by molecule to gain immunity against Concealing Eyes. A similar feat occurs in Manga Route 2, although it is unknown whether that was done by the same usage as the one shown in Novel Route. Also in Manga Route 2, it rebuilds itself and its appearance to avoid being detected by Focusing Eyes, and later to rebuild its body to become immune to even Combining Eyes' direct commands. It also displays Awakening Eyes' regenerative properties, as it managed to quickly recover itself after being hit by a landslide. Awakening Eyes' power manifests in the form of a black aura, sometimes shaped in the form of snakes, when the Snake of Clearing Eyes uses it.

Multiple

 * The Snake of Clearing Eyes seems to hold power over "knowledge" itself.   In the Novel Route, Shintaro refers to it as "a living encyclopedia with a full grasp of everything from the start of civilization up to modern science." Manga Route 2 shows that its knowledge extends to as far as knowing more about Azami's true nature, history and abilities than even Azami herself. Due to its sentience, it can directly advise its owner on how to fulfill their current biggest desire, such as when it tells Azami how to create the Kagerou Daze so that she can stay there forever with her family  or when guiding Kenjirou on how to bring his wife, Ayaka, back from the Daze.   With its human owners, it can take possession of its owner's body at will, presumably only once the sun starts to set, although it has been shown to possess Hibiya after sunrise to attack Kido. Its human hosts have no memories of what the Snake of Clearing Eyes does while controlling them.  It can jump between hosts as long as there is prolonged physical touch between the old and new hosts,   even if the old host is under the effect of Locking Eyes, although it is unknown if it can take other hosts and fully possess them besides Konoha. Doing so kills its previous host, as they lose the surrogate life that it provides.
 * The Snake of Clearing Eyes is extremely manipulative and has a wide degree of knowledge; for example, when possessing Kenjirou it was able to amass a great amount of money and power and even change parts of the city with its influence, such as creating an entire building and underground laboratory for its scientific experiments. It also hired a large number of men and organizations, including entire police departments, to do its bidding. Its influence even extends to the media, which prevented Ayano, Haruka and Takane's deaths from being fully reported on the news. It is also strong-minded enough to resist being subjugated by Combining Eyes, thanks both to the strength of Azami's wish of wanting to know who she is  and by knowing and using Awakening Eyes' full potential. The Snake of Clearing Eyes has shown to remember past Routes, although whether that is to the extent provided by Retaining Eyes is unknown. To prevent itself from losing sentience and possibly its own existence, the Snake of Clearing Eyes avoids completely fulfilling its owner's biggest desire and instead uses them and their wish for its own plan to rewind the world.

Ayano Tateyama

 * Ayano's eye ability allows her to instantly project her own (and possibly those of other people's) emotions, thoughts, and memories onto others, which she refers to as "the power of caring". In Manga Route 2, she first uses this ability to express her hatred towards Marry directly into her mind. In the present day plot, she uses Favoring Eyes to show Hibiya Azami's memories, which she observed in the Kagerou Daze. Later, at Shintaro's suggestion, she transfers Azami's memories to Marry, which helps her learn how to utilize Combining Eyes with the other abilities she has, and after that to Kano, so that he can impersonate Azami and stall the Snake of Clearing Eyes. She also uses it to ask the forest animals to cause a landslide onto the Snake of Clearing Eyes. This scene also shows that she does not need direct eye contact to send her thoughts to a group of individuals with Favoring Eyes. In the Novel Route, Azami teaches her how to use this ability by sharing her memories with her, which she tells Shintaro about by using the ability on him. She uses this knowledge to share Azami's memories with Marry, which allows Azami to temporarily manifest in Marry's body, and, later, for Marry to know how to use Combining Eyes to harness the other eye abilities. In Mekakucity Actors, Shintaro tells her to transfer certain memories (whether they are Shintaro's memories from previous Routes that he remembered with Retaining Eyes or Azami's memories is unknown) to Marry to teach her how to control the Daze.

Azami

 * Azami created the Snake of Favoring Eyes to be able to convey to her newborn daughter Shion just how much she loves her. She called this ability her 'heart'. In the Novel Route, she uses it to teach Kido how to use Concealing Eyes for memory erasure. Later, she uses it on Ayano to share her memories with her before disappearing, as once Favoring Eyes went to Ayano, she no longer had any snakes left to sustain her consciousness.

Shintaro Kisaragi

 * Shintaro's eye ability allows him to remember everything that he sees as long as the Snake of Retaining Eyes is also watching through his eyes. Shintaro gains this ability after Manga Route 2's ending, when Ayano has Marry trade her own life, which was substituted by the Snake of Favoring Eyes, to become the Snake of Retaining Eyes. Unlike the other snake owners, he has this ability since before birth in all subsequent Routes. He sometimes unknowingly uses Retaining Eyes before fully activating it, such as in Mekakucity Actors when it causes him to recall Haruka when he first meets Konoha and in Kagerou Daze -in a day's-, as indicated by his red eyes. Upon fully activating his ability, he can recall his memories from past Routes and talk to the Snake of Retaining Eyes while conscious. It is implied that in every Route after Manga Route 2, Retaining Eyes makes him subconsciously remember past Routes and easily recall things, which allows him to obtain perfect scores on tests and arcade games.   For example, he can know all the answers to an upcoming exam after only observing the required information once. That trait might also subconsciously help him to come up with complex plans and predict people's behavior even while under great duress,     although he has shown this characteristic of his even before obtaining Retaining Eyes.
