That time, so that no one (not even Father) would notice, I secretly rewrote the summary.
What cannot change can only be broken.
This is so to me, who left behind everything necessary inside the womb.
Eto Yoshimura (芳村 エト, Yoshimura Eto) is the founding leader of Aogiri Tree, having formed the organization in the decade between her original rampage and the beginning of the series. While speculated by many to be the One-Eyed King, she claims that this is not the case.
Instead, 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.
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, very 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; this resemblance is furthered when she cuts her hair to a short bob before she publicly announces she's a ghoul.
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 its appearance, spawning extra appendages, such as eyes, mouths, and limbs, if she wills it.
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 inflicting pain on others. Like many ghouls, she is able to compartmentalize her ghoul and human alter egos with relative ease.
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 the profile he constructs through his 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.
Despite her warped aspects she does seem to believe in creating a society where ghouls will not be persecuted for existing and will do anything to fulfill this ambition regardless what she has to sacrifice.
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'.Special Class Urie faced Eto. He ordered a retreat and died fighting her alone to ensure his comrades' survival. 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. 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. Subsequently, Yoshimura, acting in his daughter's place, attacked the 2nd ward for a third time alone to divert the attention of CCG and V from Eto, and was defeated and seriously injured by Kishou Arima.
During one confrontation, Eto revealed her hatred for the world, criticizing its state, and saying that the ghoul who kills Arima would be the hope for her entire race, while the latter smiled at her. They formed a plan to groom someone who would be competent enough to bear the title of the One-Eyed King, who later turned out to be Kaneki.
Sometime after this, Eto tried to become an author, showing her manuscript to Shunji Shiono. Though initially rejected, she was finally accepted and adopted the pseudonym "Sen Takatsuki," beginning her career as a novelist, at the same time planning for her next move. 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.
Around two years after her debut, Eto was already aware of her father's identity, though the sight of him visibly angered her. One night, Shiono dropped by her apartment and accidentally found human body parts inside her fridge. Despite Shiono finding out about her ghoul nature, she spared him and the two continued working together.
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. 
Owl Suppression Operation
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-Owl Suppression Operation
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.
At some unknown time Eto and Kanou have a a conversation about Koutarou Amon while observing him unconscious in a chamber. The surgeon mused about his status as a prodigy for the next generation of Ghoul Investigators and his numerous achievements during his career. Eto is dismissive noting that is in the past due to his ghoulification.
Root A (Anime)
Eto watched the 11th Ward Battle from afar with Tatara and noted that Kaneki had gotten stronger. She asked Tatara if the others would not come as many of their allies had died. She asked him about how many had died and Tatara replies about two hundred or so. Eto says that for the sake of those two hundred, they have to do their killing too.. After the Aogiri hideout was crushed, Eto follows Kaneki, smiling. Some time later, Eto welcomes Kaneki along with the other Aogiri executives as their new recruit.
Eto waited as a mission was about to begin and appeared excited when she saw Kaneki arrive. She later sneaked off to a privite room to undress. Still looking excited, she called Kaneki's name.
Eto made her appearance as Sen Takatsuki, and showed up late to an autograph session at a bookstore. She meet Hinami and quickly showed interest in her. Eto asked for Hinami's name assuming the autograph was for her, but Hinami stopped Eto from signing the book because it was a present. Eto paused when Hinami said the book was for Ken Kaneki then asked how to spell his name. Eto asked if Kaneki was her boyfriend, but flustered, Hinami said that he was like a big brother. Eto thought it cute and gave Hinami her book back before saying goodbye. After Hinami left, Eto thought about Kaneki. Later at the Aogiri hideout, Eto watched Kaneki from afar as he helped Naki and laughed.
Prior the Cochlea raid, Eto watched the facility from afar, eager to attack it. During the infiltration, she accompanied the other Aogiri ghouls in the attack to free Shachi and the other prisoners. Eto intervened in Shachi's fight with Kaneki and asked him if he wanted to see Rize. Later, after Eto danced around the bodies of dead investigators, she looked into the depths of Cochlea, planning something. She finally appeard in her full kakuja form, angering an injured Akira and bewildered Amon. She grabed Ayato and Kaneki and fled.
After the Cochlea invasion, Eto watched over Kaneki while he tried to recuperate. Since he used his kakuja for the first time, he had been unable to control it and was plagued by nightmares. While he suffered, Eto stood back smiling, interested in his progress. She later met Hinami again at her favorite café and they sat down for coffee and to talk about Kaneki. Hinami told Takatsuki about her problems and Takatsuki told her the hard truth. She and Kaneki were too different and Hinami would not be able to help him with the way she was. Hinami was saddened, but agreed. Before she left for an interview, Takatsuki gave Hinami her business card. She sympathized with Hinami and advised her to call if she needed help. Takatsuki’s went to the CCG to try and get an interview with an investigator. She was able to speak with Shinohara and Juuzou and asked them questions about the possibility of creating artificial ghouls for her next book. Shinohara did not think something like that was possible, nor was there a purpose to create more dangerous ghouls. Before she left, she gave Shinohara a tip about a coffee shop in the 20th Ward that served delicious coffee and an interesting rumor about it.
Yoshimura explained his past to Kaneki and how Eto was born. A hybrid between a human and ghoul, when Ukina became pregnant, Yoshimura had expected Eto not to survive. After he said it would take a miracle, Ukina insured that happened. Eto was born healthy and her parents were happy to have her. However, the organization Yoshimura worked for targeted them and killed Ukina. Yoshimura hid Eto in a secluded location while he fought the organization members. When he returned, Eto was gone.
Prior to CCG’s attack on Anteiku, Eto spent time with Tatara, admiring the snow.
Eto later appeared after her father was defeated, at first assuming her original kakuja guise before it morphed into a bestial like form and grinned at the investigators sinisterly. Shinohara and Iwao's suspicions about there being two Owls were confirmed with her appearance.
Eto made quick work of the investigators, looming over them with a crazed grin before she turned her attention to Suzuya. Eto was about to attack him until Shinohara took the blow instead. Angered, and desperate to save his father figure, Suzuya repeatedly tried to defeat her, but his attacks did damage at all. Eto continuously mocked him, and even stabbed Shinohara just to see him suffer. However, shortly afterwards, Suzuya's wounds caught up to him, and he fell, only to be caught by Arima. Eto quickly recognized him, saying he is finally here before attacking him. However she was unable to land so much as a hit on him, and was forced onto the defensive as she tried to dodge his attacks. When it seemed like she finally had the upper hand, Arima sliced off her arm, which forced her to flee after eating Yoshimura. She later regurgitated Yoshimura, who recognized her while she called him father in a singing tone, smiling cruelly down at him.
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.
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.
Some time later, Eto approached Kanae as he hid beneath an overpass and raged over his defeat. She taunted him with the mystery of her true nature, offering him an apple and biting into it in front of him. When he launched an attack, she effortlessly dodged and quickly overwhelmed him with her massive, abnormal kagune. She explained 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 recognized her as a one-eyed ghoul, she readily agreed with him.
Eto began to wax philosophical, questioning whether Kanae has ever read the Book of Genesis. She discussed 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 asked Kanae about his religious beliefs, and what he imagined God to be like. In her own mind, she explained, 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 told 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 pressed on. She explained 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 lectured Kanae about how his feelings of loyalty were actually possessiveness and jealousy and reminded him that Tsukiyama will never look at him. She told him that he owed nothing to someone that won't return his love, and suggested that they should destroy them instead. As Kanae broke down, she continued to mentally torture him.
Later on, Eto was keeping Kanae in captivity and subjecting him to various amounts of torture. She told 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.
She is next seen looking over the Lunatic Eclipse Building with Noro, appearing as if she's putting another plan into action.
As Sasaki loomed over a collapsed Kanae, Eto is perched on top of a towered structure, observing off in the distance. She then promptly descended into sight, swiftly destroying Matsuri's helicopter on the way down, and ambushed Sasaki from above. Successfully "flicking" Sasaki, Eto mocked him, saying that Arima would have dodged her attack effortlessly. She ordered Kanae to continue attacking Sasaki as he does not have much time until he meets his maker and watched in joy as Kanae started beating Sasaki.
When Sasaki slashed off Kanae's right arm, she caught it and showed her delight at the sudden turn of events, realizing Sasaki has regained his memories. She continued observing as the reawakened Sasaki quickly gains the upper hand and incapacitates Kanae with his kagune. After Sasaki subdues Kanae, she reactivates her kakuja and watched as Sasaki stabbed Tsukiyama in the chest with his kagune. She then commented on this, calling him cold for shedding blood just after his awakening, and asks if he is stronger than Arima. Sasaki replied that she is the cold one and tells her to die as the two start to fight.
Eto shot her projectiles at Sasaki, who successfully avoided them. He questioned Eto's motives for appearing, to which she replied 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. Sasaki told her that her father had asked him to save her. She laughed and started teasing Sasaki. However, Sasaki immediately slices off her kakuja head, missing her concealed body. She called him a kid, and Sasaki mocked her by questioning if she is worth saving.
Angered that he managed to strike her, she reformed her kakuja as a grotesque monster with multiple mouths and limbs. She lunged at Sasaki and had begun attacking him, driving her opponent to the side of the building. Eto chased Sasaki through the side of building. When Sasaki climbed back to the rooftop, Eto continued to give chase. As Sasaki stopped atop a steel bar, Eto lunged at him. However, Sasaki impaled her kakuja head with his kagune, striking with enough force to force the upper half of her body out. Gravely injured, she licked her splattered blood over Sasaki's kakugan 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 laughed maniacally while declaring her love for him. She later appeared to have fully regenerated her body and is taking a bath while happily wondering if Sasaki has regrown his arm and if "her thing" was to his liking.
Eto recalls a memory from when she was fourteen years old when she was engaging Iwao Kuroiwa in battle. She thinks of the years she's been with Aogiri and the identity "Takatsuki" for 13 years, and states she's getting old. She assembles the Aogiri Tree members and announces a great change for the Aogiri Tree, despite the fact that their numbers were lowered due to recent actions of CCG. She reveals both her ghoul identity as the "One-Eyed Owl" and her human one as Sen Takatsuki. She informs subordinates about her attempts to fight the CCG and eventual defeat 13 years ago, which ultimately led to her founding Aogiri Tree. Despite the organization now being thousands of individuals strong, she tells them their goal of ghouls living freely in the human world is still far away. She elaborates further, stating that although their enemy is CCG, she tells the faction that her true aim is to exterminate the "warped root" that lurks behind it to destroy the "twisted birdcage" they live in and return balance to the world. Eto informs them that the predecessor organization of the CCG was founded because of the appearance of an extremely powerful one-eyed ghoul, and that one-eyed ghouls are seen as portents of great change. She then reveals that despite her role as Aogiri Tree's founder, she, the One-Eyed Owl, is actually not the King.
Sometime later, Eto appears alongside Sasaki inside Shiono's interrogation room. She compliments Sasaki for having developed some good "eyes", and apologizes to Shiono for putting him in trouble. Having testified against her, Shiono kneels before her and apologizes profusely. As Sasaki declares her arrest, she tells him that if he believes to have won, he should get ready to shut her mouth. She then tells Shiono she bears no grudge against him, and thanks him for making her an author.
Now under CCG custody, Eto is under Sasaki's watch. Despite her situation, she manages to convince the CCG and her management to let her have a final press conference about Sen Takatsuki's last work. She cuts her hair short for this event, which Sasaki commented as unusual for someone under CCG watch to do but nonetheless suited her. Eto asks Sasaki to accompany her to the press conference, which he complies to despite his suspicions. At the press conference, Eto reveals that her last work is something she's been wanting to do for a long time. She confesses that she is a ghoul, and dedicates the book to her fellow ghouls. Her confession is broadcasted throughout Tokyo.
At a later point in time, Sasaki accompanies Eto through a facility and explains the procedures. She'll be temporarily held at Corniculum until it's officially confirmed that she's a ghoul, then transferred to Cochlea. Sasaki tells her that he read her book, which she's grateful for. He ask of her intentions regarding the book, but Eto states the purpose is already what she had said: King Bileygr is an offering the King and a symbol of hope for ghouls. None the less, she explains further. The human run corporation in the book is based on the Washuu Clan and she believes they're working with ghouls, so intends to spread distrust about the family. The inspiration for her efforts was her mother's notebook where she found information about V. The same notebook where she also learned that her mother became close to Kuzen because he was a member of V and she's a surplus of that relationship. Sasaki doesn't believe her however, so she gives him a piece of information that'd be difficult for him to dispute.
Eto brings up the time he passed through an Rc Scan Gate without setting it off, back before he was taken in by the CCG, and states how unusual it is he wasn't detected despite his high Rc count. She explains that this is because the gates are programmed to exclude specific patterns exhibited by the ghouls of V, and by extension, those with certain relations. The Rc Scan Gates don't detect her because she's the daughter of Kuzen, neither the body of Ken Kaneki because he has the kakuhou of Rize, who escaped V.
Sometime later, Eto is placed in a cell. Furuta comes to visit her and cheerfully comments that her short hair suits her well. She orders him to be silent while calling him "Kanou's clown". Furuta is amused by Eto's extensive knowledge and flaunts his own about Aogiri. Eto goes over the mischievous things he's done over the years since working for Kanou, like collecting samples for ghoulification experiments, alerting Aogiri to the transport of a Quinx body, and dropping steel beams on people. Eto expresses confusion over how his actions relate to V, but Furuta is reluctant to reveal his motives. He diverts the conversation towards Eto's own goals, confused himself about why she wouldn't rather stay on Rushima, but Eto claims that she has nothing left to do. Furuta finds her attitude attractive and begins to flirt, expressing his desire to dominate her until Eto expresses her curiosity about what he wants with her. He wants to know about the One-Eyed King and is willing to make a trade: reveal their identity and Eto would be allowed to live in the VIP rooms of Cochlea until she dies.
Furuta talks a bit about his predecessors, about how they've long learned how to control the masses if they divert their attention to a common enemy, which gives them the freedom to do whatever they like. However, Eto and the One-Eyed King are irregular enemies and have made things difficult. Eto expresses relief that they don't know anything about the One-Eyed King and Furuta goes over his efforts to uncover information, from sneaking into a Ghoul Salon to joining the Clowns. His efforts proved fruitless however as even those in the know knew nothing about the King, some believing that the King is merely a symbolic figure to rally the ghouls. Eto denies this and says the King does indeed exist "in their bellies". Furuta tries to enforce that the current sense equilibrium is ideal and that Eto's attempt at revolution would only harbor pain and sadness, but Eto calls out the hypocrisy as ghouls get the short end of the stick. Seeing as Eto didn't provide the information he sought, Furuta ends the meeting and begins to walk away grinning at the prospect of her execution and the spectacle he'll make when it happens. Eto refers to him as "Washuu" and taunts him for not being able address his own father. Aggravated, Furuta repeatedly tells her to die, which only amuses her further.
However, Eto had secretly asked Sasaki to plant a tape recorder in the room, which he retrieves after Furuta leaves. While Sasaki listened to the recorded conversation, Eto warns him that his "last job" will be harder than he thinks. Sasaki asks if she knows what he's going to do next which Eto claims she does as being observant comes with being an author. She offers to help in exchange for granting her a final wish, but Sasaki replies that he has made no plans beyond his "last job" and has no interest in her request. Eto's left a bit exasperated by Sasaki's attitude, but leaves the offer open and divulges her wish anyway; She wants Sasaki to kill the One-Eyed King.
Third Cochlea Raid
On the day of the Rushima operation, Eto is transported to Cochlea.Furuta once more visits her in her cell under the pretense of giving her food. Furuta tells her that Shiono did his best to ensure her last book was published despite the agency's attempts to prevent it. This prompts Eto to ask if he's dead, which Furuta confirms by revealing that he is her meal. Eto thanks him for the meal when the alarms in Cochlea started ringing. As Furuta rushes to investigate, he reveals that he had known Eto had recorded their conversation, but he has kept that information to himself for personal reasons. He then leaves Eto with her meal.
During Arima and Sasaki's fight, Eto is still confined in her cell, noting that Sasaki is giving his all against the investigator.
As the disposal compactor is initiated, Eto ambushes Furuta and V, completely breaking the machines and killing several members. She declares that Shiono's death won't go to waste and that she will kill Furuta next. Eto begins to chase Furuta across the floor above Cochlea's compactor, easily crushing the V group along the way. While Furuta tries to "reason" with her, she mockingly requests him to fight her. As she corners Furuta to a wall, her kakuja is suddenly butchered to pieces by Furuta's kagune, who reveals his kakugan in his right eye.
After their battle, beaten and injured, Eto inquired about Furuta's kagune being Rize's, which he affirmed. She then asked what Furuta's true intentions are, to which the latter responded that he wanted super peace, and walked away. She then met Kaneki along with Squad 0, greeting the ghoul while claming that she is going to die and that she aided Anteiku in escape but was confronted by Nimura Furuta. As Kaneki said that her actions were reckless, she responded by saying that everyone who keeps a promise is reckless. Afterwards, she told Kaneki that there is no need to heed to her request to kill the one eyed king, while peacefully closing her eyes.
Having been separated from her father as an infant, Eto does not share a close bond with him. She has an intense hatred for her father for running away. She sees her father only as a way to further her own goals. As such, she has no qualms about using him for experiments.
As Ukina died shortly after Eto was born, Eto only knows her through her diary. Even so, Eto holds her in high regard. She respects Ukina for her courage and assures her mother she will not run away like her father. This seems to be the reason behind many of her actions as Ukina was intent in pursuing V at the time of her death. However, Eto also holds doubt about Ukina's love for her interpreting her own birth as just a byproduct of trying to get close to V.
Tatara is one of the closest Aogiri members to her, and she was 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.
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".
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 because Eto talked her up into joining the organization, taking advantage of her insecurities as well as the loss of both her mother and Kaneki. However, it's still unknown how their relationship has developed after their first encounter, since Hinami doesn't talk about her with much animosity, in spite of everything Eto's put her through.
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:, Eto reveals that her feelings for Kaneki run deep. She states that she has grown fond of Kaneki, and believe they are similar, referring to their personalities and their nature as one-eyed ghouls. Eto has stated that she "loves" Kaneki, albeit in her own twisted view of it. After her capture, Eto develops an uneasy but friendly relationship with Kaneki. She relays crucial information to him regarding V, her past, and the incidents that have happened. She entrusts Kaneki with her wish, though Kaneki states he doesn't know what she meant.
She eventually reveals to Kaneki that she and Arima had been "raising" him in order to create a Ghoul that could one day kill him, and become the hope Ghouls need in a distorted world.
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.
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. Since their encounter years ago, they had been acting together in secret, creating a ghoul that could kill the CCG's Reaper.
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.
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.
The former Investigator turned Ghoul answers to her, and while their exact relationship remains unclear, she speaks to him with a friendly tone. Even so, Seidou as shown annoyance at her sneaky behavior, such as sending him to fight Haise.
As Sen Takatsuki's editor, Shiono 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. Eto is grateful to him for helping her become an author, and shows him more patience than she would most humans, even deciding to spare him after he accidentally found out about her ghoul nature. When he eventually testified against her, Eto commends him for withstanding an interrogation, and apologizes for putting him through such trouble.
Eto and Furuta have a very hostile relationship. Their conversations, though masked under smiles and pleasantries, are laced with heavy insults and both harbor a strong desire to see the other dead. They will not hesitate to use any means to get under the other's skin. Additonally, Eto seems to know a lot about Furuta such as his role in helping Kanou and causing Rize's accident, and his secret status as a Washuu.
Powers and Abilities
Ghoul Physiology: As the only known Half-Ghoul hybrid, Eto inherited all ghoul abilities of her father, along with the enhanced prowess due to the hybrid vigor.
- Ukaku Kagune: 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. Her kagune appears to be an extension of her conciousness as the mouths often speak incoherent sentences, possibly her thoughts at the moment. 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).
- Ukaku Kakuja: 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 Yukinori Shinohara and Iwao Kuroiwa through brute force alone. Unlike most kakujas, she is able to maintain her consciousness. Much like her kagune, she is able to change the physical form of her kakuja, spawning extra appendages like limbs, mouths and eyes at will. It also has the potency of obliterating a huge disposal machinery at Cochlea.
- Kagune Detachment: Eto demonstrates the ability to detach pieces of her kagune, using them to manipulate and restrain targets. It is possible this is a variant of the kagune wall, though the exact details are unknown at this time.
- Superhuman Durability: Eto was completely unfazed from getting severed below her abdomen by Kaneki, and could also endure being defeated and smashed into a wall by Furuta.
- Superhuman Regeneration: After her clash with Kaneki, Eto regenerated her entire lower half during the timeskip.
- Superhuman Agility: Eto demonstrates a high level of agility and speed on numerous occasions. Notably, she was able to move so swiftly that Kuro and Shiro were unable to visually track her movements. Shortly afterwards, she demonstrated speed sufficient to remove several of Banjou's ribs without him noticing the injuries.

Her son, the protagonist, is disgusted by his mother's depravity, but has to realize that he is developing the same cruel impulses. The book combines brutal descriptions with a delicate portrayal of the main character's mental state. After the organ transplant, Ken Kaneki likens himself to the story's protagonist.

- King Bileygr (王のビレイグ, Ō no Bireigu), her tenth and final work, is a heroic drama. It features the one-eyed ghoul "Nameless" as its heroic protagonist. "Nameless" leads his fellow ghouls as their "King" in a rebellion against the world that oppresses his kind. The human organization featured in the novel, seemingly fashioned after the Washuu clan, is revealed to be covertly cooperating with ghouls.

- In the English edition of Volume 4, Kureo Mado in Touka Kirishima's flashback in Chapter 31 and Kaneki's thoughts in Chapter 34 were mistakenly translated to refer to Eto as the "One-Eyed King." Instead, these lines should refer to her as "One-Eye."
