Eto Yoshimura


 * "One-Eyed Owl" directs here. For the artificial One-Eyed Ghoul, Owl, see Seidou Takizawa. 

Eto (エト, Eto) is a member of Aogiri Tree, often seen interacting with fellow Aogiri member, Tatara.

She is the One-Eyed Owl (隻眼の梟, Sekigan no Fukurō), the half-human, half-ghoul daughter of Yoshimura and Ukina. Her human identity is Sen Takatsuki (高槻 泉, Takatsuki Sen), a best-selling horror novelist mentioned throughout the series.

It is speculated that she is One-Eyed King of Aogiri Tree by the CCG, Nico, and Kaneki due to her unique nature among ghouls and apparent association with several high-ranking Aogiri officials, most notably Tatara.

Appearance
As Eto, she has a child-like appearance. Her entire body is wrapped in bandages, with tattered maroon cloak with droopy ears attached to the hood. She wears a floral scarf around her neck. Her right eye is a kakugan, while the other eye is a normal green eye.

As Sen Takatsuki, she is a short, attractive woman in her mid 20s. She typically wears a sleepy or curious expression and dresses in modest or sloppy fashion. Her long green hair is usually messy and uncombed or bundled on top of her head in a messy bun. However, even though she is typically unkempt, she is noted to be an incredible beauty with many admirers and greatly resembles her mother, Ukina.

As the One Eyed Owl, her single Kakugan is in her right eye, and her initial Kakuja created a mask with one hole on the right eye's position and three zigzag lines on the left, with two lines at the mouth's position slanted downwards, which greatly resembled her father, Yoshimura's Kakuja mask. After 10 years of cannibalizing, presumably, her massive Kakuja now forms a mask like-head with four horns and a single eye in the center of the mask with three markings on the left and right cheek and the forehead, and a huge smiling mouth. She is however, able to alter it's appearance, spawning extra appendages, such as eyes, mouths, and limbs, if she wills it.

Personality
Eto has a sadistic personality,often expressing joy at the expense of others' suffering. Her twisted personality is possibly the result of fighting to stay alive during her early years in the 24th ward. As a result, she has no qualms about remorselessly slaughtering humans and ghouls alike, and shows happiness when infliciting pain on others. Like many ghouls, she is able to compartmentalize her ghoul and human alter egos with relative ease. Since she doesn't see any value in human life, this indicates that she has a misanthropic view on humanity.

As Sen Takatsuki, Eto projects a childish air around her through her actions and overall demeanor. She appears to be quite playful and ditzy at times, oversleeping on the day she was supposed to be signing books and taking photos with admirers when it was prohibited by her manager. According to Haise Sasaki in his profile he constructs through the analysis of her works it leads him to speculate that the author is a woman filled with despair and hatred towards the world, having completely abandoned hope long ago.

Like her mother, Eto has a very sharp intuition about the feelings and desires of people, which she exploits to the fullest when dealing with her victims and manipulating others to do her bidding.

Past
Eto was born to Ukina and Yoshimura as a hybrid human and ghoul being. Because her mother had secretly been investigating the organization V, they forced Yoshimura to kill his lover as punishment for "betraying" them. In order to protect his infant daughter from them, Yoshimura entrusted her to the care of a Ghoul known as Noroi and left her in the 24th Ward with her mother's diary. It is unknown what exactly happened to her in the following decade or so, but she would emerge from the 24th Ward as a Kakuja and begin a bloody rampage.

During a routine Whack-a-mole operation, a team lead by Itsuki Marude encountered Eto deep within the 24th Ward and was quickly overwhelmed. Associate Special Class Kasuka Mado stayed behind so the others could retreat, sacrificing her life to protect her husband and comrades. A later investigation found that Eto had torn the Investigator to pieces, and scattered her partially-devoured remains everywhere for them to find. In response, Kureo Mado began a quest for revenge that would later consume him.

One day, Eto appeared for the first time and single-handedly killed a Special Class Investigator that was affiliated with the 3rd ward. Eto was assigned a S-rating and then given the nickname X.

One month later, Eto executed a large-scale attack on CCG's 2nd ward branch office. The office was heavily damaged and CCG suffered numerous casualties. Eto's rating was increased to SS, and her nickname was changed to 'Owl', due to her plumage-like Kagune. After a report of Eto only having one kakugan, her nickname was again changed to 'One-Eyed Owl'.

Afterwards, Eto and other ghouls attacked the ghoul detention center Cochlea in the 23rd ward. Eto's rating was upgraded to SSS.

During the course of her various attacks, the S3 Squad lead by Special Class Urie encountered Eto. He ordered a retreat and faced her alone to ensure his comrades' survival, dying in the process. Iwao Kuroiwa and the other survivors later reported this news to a young Kuki Urie, who swore to one day avenge his father.

Later, Eto's faction attacked the 2nd ward for a second time. This time, First Class Investigator Kuroiwa dealt heavy damage to Eto's kakuhou with his Quinque. However, Kuroiwa himself was seriously injured and could not participate in subsequent operations.

Finally, Yoshimura, acting in his daughter's place, attacked the 2nd ward for a third time alone. CCG's team was unable to exterminate Yoshimura. However, the genius Rank 2 Investigator Arima used the Special Class Investigators' quinques as he went up against Yoshimura. Finally, he defeated Yoshimura, leading to CCG's victory. Yoshimura, wounded, vanished after this day ten years ago.

At an unspecified point during her teenage years, Eto would adopt the human identity of "Sen Takatsuki" and begin her career as a novelist. Her first work, titled Dear Kafka, would go on to be a best-seller and help establish a strong following as an author. She published five other works, before publishing The Black Goat's Egg -- the very novel being read by Ken Kaneki and Rize Kamishiro at the beginning of the series.

Aogiri Arc
Eto attended the meeting where Kaneki was brought before Tatara. At the end of the meeting, Tatara left the Aogiri hideout's affairs to Noro. Tatara predicted that the doves would come soon and ordered Noro to follow their plan. Then, Tatara left with Eto to meet comrades that were waiting for them.

Raid of Kanou's Lab
Eto is among the members of Aogiri gathered while Tatara interrogates Dr. Kanou's assistant about his location. She briefly chats with Naki about Yamori's death, suggesting that Tatara should have killed Kaneki when he had the chance. Once the group have their information, she joins Tatara to discuss making their move before the Doves can.

She is among those sent to raid Kanou's lab, and uses the chaos to sneak deeper into the facility alone. There, she encounters the twins Kuro and Shiro, and begins to taunt them about their past. Displaying incredible speed, she is able to seemingly teleport around the room while asking them painful questions. Once her psychological tactics overwhelm them, she appears behind Kazuichi Banjou and rips out several of his ribs.

Later on, she joins Kanou in his control room and watches the confrontation between Koutarou Amon and a deranged Kaneki. She expresses interest in Amon, before leaving the facility along with Kanou.

Anteiku Raid
In the aftermath of the battle at Dr. Kanou's laboratory, she makes her first appearance as Sen Takatsuki at a book signing event. She arrives late to the event, and apologizes to the large gathering of fans for having overslept. While her manager protests, she cheerfully ignores the rules of the event and mingles with her fans taking photographs and chatting happily about the books. Kaneki and Hinami Fueguchi attend the event, and immediately catch her interest. She is pleased that Kaneki notices so many hidden details in her novels, while she forms an immediate connection with Hinami. After they leave, Hide arrives at the event and briefly chats with the author. She hints at her interest in writing a novel about a Ghoul.

Some time later, she observes Hinami having coffee with Shuu Tsukiyama and waits until the girl is alone before approaching her. She reveals that Hinami has a habit of clutching her hands when lying, and offers the girl honest advice about her inability to help Kaneki. Takatsuki claims to have gone through difficult times in the past, and gives her business card to Hinami, offering her assistance should the girl ever need it.

Later that day, she pays a visit to CCG and claims to have information. Amon meets with her, answering her questions about the RC scanner gates -- which she passes through without incident due to her hybrid nature. Once seated in an interview area, she begins to question him about personal things such as his lunch, stating that she wants an interview with an Investigator in exchange for the information she has. Amon is initially frustrated with her teasing behavior, but once he cooperates she reveals to him a conspiracy involving CCG and a trading company called Sphinx. She reveals that the company sold CCG a large amount of a fluid made from Ghoul corpses, and that Dr. Kanou's mansion was in fact property of CCG. Furthermore, she reveals that the president of Sphinx, Nanao Yasuhisa was murdered by a Ghoul. Having provided Amon with enough information to make him question CCG, she leaves.

She next appears during the battle in the 20th Ward, ambushing the team sent to kill Yoshimura in her full Kakuja form. Exhausted from the previous battle against her father, Iwao Kuroiwa, Yukinori Shinohara, Kousuke Houji, Koori Ui, and Juuzou Suzuya are quickly overwhelmed. She tortures and fatally wounds Shinohara, taunting a wounded Juuzou and batting him around until the remaining Special and Associate Special Classes arrive. They are barely able to hold her off, until the arrival of Squad 0 that led by Kishou Arima. Arima fights her in single combat, inflicting numerous serious injuries and forcing her to retreat. Before she flees, she swallows her father whole and leaps from the rooftop with him -- mocking CCG as she makes her escape. Later on, she regurgitates her father unharmed and emerges naked from her Kakuja armor. She greets her father with a deranged expression, revealing that Sen Takatsuki, Eto, and the One-Eyed Owl are all the same person.

Post-20th Ward One-Eyed Owl Battle
She is later seen talking with Tatara and Dr. Kanou, suggesting that they will simply have to replace Kaneki with a new one -- one created from her father and kidnapped Investigators.

In the aftermath of the battle, Tsuneyoshi Washuu theorizes that the One-Eyed Owl and the One-Eyed King of Aogiri are the same person. He reaffirms that she must be defeated at any cost.

Root A (Anime)
In their battle, Kaneki was noted by Eto, who was watching from afar with Tatara, to have become much stronger.

Eto asks Tatara if the 'others' won't come as many of their allies seem to have died, and she asks him about how many have died. Tatara replies 'About two hundred or so'. Eto then says that for the sake of those two hundred, they have to do their killing too.

After the Aogiri hideout is crushed, Kaneki sees the bodies of the dead investigators on the ground. He sees what seems to be an illusion of Eto smiling at him.

Kaneki is welcomed by the main executives of Aogiri, with Eto waving her hand at him and Ayato being visibly annoyed. Kaneki follows as they all leave the place.

During the Cochlea infiltration at CCG headquarters, she is seen along with the other Aogiri ghouls producing chaos in order to free Shachi. After his fight with Kaneki, Eto asks Shachi if he wants to see Rize. Later, Eto is shown to be watching over Kaneki as he fights Shinohara and Amon. She finally appears in her full Kakuja form, angering an injured Akira and bewildered Amon. She grabs Ayato and Kaneki and flees.

Eto later appears after her father was defeated, at first assuming her original Kakuja guise before it morphs into a bestial like form, grinning at the Investigators sinisterly. Shinohara and Iwao's suspicions about there being two Owls are confirmed with her appearance.

Eto makes quick work of the Investigators, looming over them with a crazed grin before turning her attention to Suzuya, about to attack him until Shinohara takes the blow instead. Angered, and desperate to save his father figure, Suzuya repeatedly tries to defeat her, but his attacks do no damage at all. Eto continuously mocks him, even stabbing Shinohara just to see him suffer. However, shortly afterwards, Suzuya's wounds catch up to him, and he falls, only to be caught by Arima. Eto quickly recognizes him, saying he's finally here before attacking him. Unfortunately, she is unable to land so much as a hit on him, and is forced onto the defensive as she tries to dodge his attacks. When it seems like she finally has the upper hand, Arima slices off her arm, forcing her to flee after eating Yoshimura. She is later seen regurgitating her father, who recognizes her while she says "father" in a singing tone, smiling cruelly down at him.

Nutcracker Investigation
Eto appears at the Aogiri Hideout, speaking to Ayato. She requests him to act as an escort and guard for Madam at an upcoming auction, since Aogiri earns lots of money through working for Madam. She also mentions that Ayato should "tidy up" if a floppy comes to the Auction.

Auction
During the Auction, Dr. Kanou and Eto observe the unfolding events from a control room at an undisclosed location. Kanou is pleased with how things are going, and asks permission to release "Owl" -- she agrees with this idea and contacts the new Owl over the radio. It is revealed to be former Investigator Seidou Takizawa, transformed into an One-Eyed Ghoul by Aogiri. He complains to Eto about being hungry.

Later on, while facing Sasaki and realizing who he actually is, Takizawa states this must have been her real reason for sending him.

Rosewald Investigation
Eto is seen first observing Haise and the Quinx fight off the members of Aogiri, hired by Kanae von Rosewald. As they ward off the members of the Yamori clan, she laughs and says that they are good.

Some time later, Eto approaches Kanae as he hides beneath an overpass and rages over his defeat. She taunts him with the mystery of her true nature, offering him an apple and biting into it in front of him. When he launches an attack, she effortlessly dodges and quickly overwhelms him with her massive, abnormal kagune. She explains that while quantity and quality of one's Rc cells determines the potential size of a kagune, it is one's intelligence and imagination that determines the potential shape. When he recognizes her as an One-Eyed Ghoul, she readily agrees with him.



Eto begins to wax philosophical, questioning whether Kanae has ever read the Book of Genesis. She discusses the story of Eve and the Fruit of Knowledge, stating that this is her favorite from the book. The idea of God telling humans not to eat the Fruit seems malignant to her, because putting the Tree there was like as its purposed to tempting humans to eat the fruit. She asks Kanae about his religious beliefs, and what he imagines God to be like. In her own mind, she explains, God is probably a child with incredible power -- explaining the many problems in the world. She goes on to offer an example of such a problem......namely, Kanae's own situation. She tells him that should he fulfill his master's wishes, he cannot have what he truly wants.

Seeing that her words are having an effect, Eto presses on. She explains to him that what he truly wants is to make Haise Sasaki suffer, that his actions have never been for the sake of his beloved master. Ruthlessly, she lectures Kanae about how his feelings of loyalty were actually possessiveness and jealousy and reminds him that Tsukiyama will never look at him. She tells him that he owes nothing to someone that won't return his love, and suggests that they should destroy them instead. As Kanae breaks down, she continued to mentally torture him.

Later, it is revealed that Eto is keeping Kanae in captivity and subjecting him to various amounts of torture. She is telling him that if he wants to be treasured, he has to take away what matters most to Shuu Tsukiyama while she gave him one of her seemingly detached Kagune.

Tsukiyama Family Extermination Operation
She is next seen looking over the Lunatic Eclipse Building with Noro, appearing as if she's putting another plan into action. As Sasaki looms over a collapsed Kanae, Eto is shown perched on top of a towered structure, observing off in the distance. She then promptly descends into sight, swiftly destroying Matsuri's helicopter on the way down, and ambushes Sasaki from above. Successfully "flicking" Sasaki, Eto mocks him, saying that Arima would've dodged her attack effortlessly. She orders Kanae to continue attacking Sasaki as he does not have much time until he meets his maker and watches in joy as Kanae beats Sasaki.

Suddenly, she observes Kanae's cut off right arm flying into the air, and appears quite surprised and delighted while catching it, realizing it was the "awakened" Kaneki who did this. She continues observing as the reawakened Kaneki quickly gains the upper hand and incapacitates Kanae with his kagune. After Kaneki subdues Kanae, she reactivates her kakuja and watches as Kaneki stabs Tsukiyama in the chest with his kagune. She comments on this, calling him cold for shedding blood just after his awakening, and asking if he is stronger than Arima. Kaneki replies that she is the cold one and tells her to die as the two start to fight.

Eto shoots her projectiles at Kaneki, who successfully avoids them. He questions Eto's motives for appearing, to which she replies she is passing time by watching the situation between Kaneki, Kanae, and Tsukiyama unfold, and is curious as to who would be killed amongst the three. Kaneki tells her that her father had asked him to save her. She laughs and starts teasing Kaneki. However, Kaneki immediately slices off her kakuja head, missing her concealed body. She calls him a kid, and Kaneki mocks her by questioning if she is worth saving.

Angered that he managed to strike her, she reforms her kakuja as a grotesque monster with multiple mouths and limbs. She lunges at Kaneki and begins attacking him, driving her opponent to the side of the building. Eto chases Kaneki through the side of building. When Kaneki climbs back to the rooftop, Eto continues to give chase. As Kaneki stops atop a steel bar, Eto lunges at him. However, Kaneki impales her kakuja head with his kagune, striking with enough force to force the upper half of her body out. Gravely injured, she licks her splattered blood of Kaneki's nose and tells him that she has grown fond of him due to them being the "same", before being severed in half from the waist up. As her upper half falls, she laughs maniacally while declaring her love for him. She is mentioned to have most likely survived the encounter by Kaneki.

Yoshimura
Having been separated from her father as an infant, Eto does not share a close bond with him. She appears to have little to no true feelings for her father other than his usefulness to Aogiri Tree, saving him from being killed by CCG investigators only to use his kakuhou for ghoul experiments.

Ukina
It is unknown whether Eto knows about her mother's death. However it can be presumed that Eto knows about their relation since Yoshimura left Ukina's diary with Eto when he dropped her off as an Infant in the 24th ward.

Tatara
Tatara is one of the most closest Aogiri member to her, and she almost always seen in his presence. The two often converse together, whether about Aogiri or more trivial matters. Their dynamic seems to be that of an older and younger sibling, though it is unclear whether this is more intentional misdirection, considering Eto's true age.

Noro
Eto was entrusted to Noro, back then known as Noroi, when she was a child. Not much is known about them in the years between. As Noro, he is her direct subordinate and often seen by her side. In his final moments, he says goodbye to Eto, stating he'll see "her on the other side".

Hinami Fueguchi
The two initially meet at a signing event, and form an immediate connection. As Sen Takatsuki, Eto later approaches Hinami in a coffee shop and strikes up a conversation. She treats the younger girl with kindness, but also refuses to candy-coat her words and offers her genuine advice. As such, she quickly earns the girl's trust and establishes herself as a surrogate older sister. She provides her contact information, promising to offer help when she has the time to do so. Two years later, Hinami has become a member of Aogiri and was likely brought in after catching Eto's interest.

Ken Kaneki
The plans of their relationship is complicated, as a result of the many identities Eto has assumed. In her human identity as Sen Takatsuki, she is one of his favorite authors and someone he admires greatly. She is pleased with his ability to pick up on hidden details in her books, and they enjoy a brief discussion of her works. Their meeting renews his energy, while she claims to have found something hopeful in talking to him.

Kaneki is one of the few aware of her true origins, having learned it from Yoshimura. This brings him some uncertainty, even though he considers her a deadly enemy to be destroyed. While chiding Tatara for sparing Kaneki's life in the beginning, Eto seems to consider him interesting after witnessing his mutation into a partial Kakuja. She refers to him as "Kakuja's Egg", and while he seeks to destroy Aogiri, she seems to have some unknown plans for him.

In Re: it has become known that Eto's feelings for Kaneki run deep, as she states that she has grown fond of Kaneki, and believe they are similar, referring to their twisted personalities, pasts and their nature as one-eyed ghouls. Furthermore, Eto screams her "love" towards Kaneki. The exact nature of her "love" however, is currently unknown.

In Root A, she seems to be interested in Kaneki, because of his new powers. After the building of Aogiri starts collapsing, Kaneki is stalked by Eto who influenced him to join Aogiri knowing he will grow stronger. She also collected research about him by questioning different people.

Kishou Arima
Arima is the only known human who was able to fight Eto in her Kakuja form. His reputation made Eto eager to fight him when he arrived with his squad, but retreated later. She describes him as a ruthless person who does not hold back.

Koutarou Amon
Eto is fascinated by him, taking an active interest in Amon after witnessing his battle against a deranged Kaneki. She seems to know quite a bit about his past, considering this unusual and noteworthy enough to make him more interesting than the half-Ghoul Kaneki. In her human identity, she goes to CCG headquarters to meet with him under the guise of an interview. There, she discloses information about Kanou's laboratory, and causes him to begin questioning the secrets CCG might be hiding.

Akihiro Kanou
As co-conspirators, the two seem to be on good terms. The doctor is amiable to her, and she in turn seems to be interested in this very unusual human.

Seidou Takizawa
The former Investigator turned Ghoul seems to answer to her, and while their exact relationship remains unclear, she speaks to him with a friendly tone. When realizing her true intentions, he rudely comments on her sneaky behavior.

Kanae von Rosewald
Eto shows interest in Kanae's involvement with Tsukiyama and Kaneki, and to that end captured and tortured her. She appears to enjoy toying with Kanae and sees her as a tool for her amusement.

Shunji Shiono
Eto's manager as Sen Takatsuki. He accompanies her to her autograph sessions and tries to keep things orderly. Her energetic and eccentric nature makes him anxious, especially when she makes unreasonable requests.

Powers and Abilities
Eto is the most powerful Ghoul seen thus far in the series, possessing an SSS ranking which she earned at age fourteen. She is very well-versed in manipulation, torture and psychological warfare, able to mentally break down a person's mind and force them to accept her ideas with ease through methodical torture. She possesses incredible agility and speed surpassing most ghouls, able to close large distances almost instantaneously and injure her opponent before they even realize it. Among her other assets she also possesses incredible resilience, being able to hold her own with Arima Kishou, CCG's strongest investigator during their brief encounter. Eto is much stronger than most ghouls, evident by her attacks in CCG headquarters and the number of investigators that she has killed as the One Eyed Owl. She easily subdues a team of high class investigators prior to Arima's arrival whereas Yoshimura had trouble fending off the same investigators' cooperative attacks. She is the strongest and most dangerous ghoul to date with 6-8 Kakuhous that help expand her kagune abilities. Arima and Kaneki are so far the only one's capable of besting her in combat.


 * Ukaku Kagune: Eto's kagune takes the form of two muscular blades on her shoulder blades and 6-8 kakuhou form spikes from her back that can shoot bullets similar to her father's. Due to the high number of kakuhous in her body, her kagune abilities are very diversified. Combined with her knowledge about Kagune and her creativity, Eto's skill with her kagune is far more advanced than most ghouls shown so far. After the timeskip, her kagune takes the form of multiple grotesque appendages attached to her back. The appendages can be shaped into eyes, mouths, arms, and legs in order to suit Eto's purposes. They appear to be sentient as they speak and express their opinions about Kanae's flesh tasting terrible and encouraging Eto to kill him. Her kagune appears to be more than a limb for her to hunt with and more like an extension of her consciousness. Like Nutcracker, her kagune is also detachable, capable of ensnaring her opponents with relative ease. She appears to be able to "implant" her kagune into others and significantly alter their physiology, as she did with Kanae (and possibly Noro).
 * Kakuja Kagune: Due to the low concentration of humans in the 24th Ward, Eto cannibalized ghouls at an early age and quickly became a kakuja. Ten years ago, Eto's kakuja formed two large scimitar blades from her shoulders to counteract the close-combat weakness most ukaku ghouls have. With two large blades, she could cover the distance between her opponents, parrying incoming attacks and striking back. Eto's first kakuja kagune also formed a mask with one hole on the right eye's position and three zigzag lines on the left, with two lines at the mouth's position slanted downwards, deceptively similar to her father's mask. In her current full kakuja form, Eto takes the appearance of a large, monstrous creature with her Ukaku kagune growing into large spikes protruding from her back, has four scimitar blades instead of two from her shoulders, large bird-like feet, and her mask develops four horns along with a single eye in the center with three markings on the side cheeks and the forehead. In this form, she is nearly unstoppable. While her ukaku kagune covers middle to far distances, her Kakuja cuts down those in front. Her ukaku kagune are capable of shooting projectiles large enough to overwhelm most seasoned CCG investigators. The projectiles were also able to knock out an Arata Proto equipped Yukitori Shinohara and Iwao Kuroiwa through brute force alone. Unlike most kakujas, she is able to maintain her consciousness. So far, Kishou Arima and Ken Kaneki are the only combatants able to stand on equal footing with Eto in this form. After the timeskip, her kakuja appears to have increased even further in size, to the extent where its tongue is bigger than her actual body. Much like her kagune, she is able to change the physical form of her kakuja, spawning extra appendages like limbs, mouths and eyes by will.

 * It is shown through her works with how the main character dies that she may have succumbed to despair and has no hope for anyone. This may be why she wants to destroy everything.
 * In Chapter 42 of :re, Kanae mutters "The One-Eyed...". Eto merely answers, "Yes." It is unknown whether or not she confirms to Kanae that she is the One-Eyed King, as Nico and CCG suspect, or the One-Eyed Owl to the vagueness of the answer.
 * In Tokyo Ghoul Trump, she is featured as the "Queen of Clubs".
