Humanoid beings that feed exclusively on human flesh, and possess enhanced physical traits. They typically live in hiding, periodically hunting human victims in order to survive. In turn, they are hunted by the Investigators of the Ghoul Countermeasures Bureau. Half of the series focuses on their viewpoint, and the conflicts between various factions of Ghouls.
Animal Motifs: Many Ghouls are associated with a particular animal, used as part of their cover when hunting.
Cannibalism Superpower: It is possible for a Ghoul that devours other Ghouls to mutate, becoming one of the rare Kakuja types.
Cool Mask: Many Ghouls wear a mask when hunting or fighting, to protect their identities.
Cynicism Catalyst: It is shown that many young Ghouls struggle with the idea of killing humans, but grow into ruthless killers after their loved ones were slaughtered by Investigators.
Game Face: When revealing their true nature, their eyes become black with red pupils.
Tainted Veins: Raised, red veins sometimes appear at the outer corners of their eyes when showing their true nature.
Horror Hunger: Ghouls are defined by their need to devour human flesh to survive.
Made of Iron: Ghoul bodies are extremely durable and are able to survive wounds that would otherwise be fatal for normal humans.
Natural Weapon: All Ghouls have a specialized extra "limb" used for fighting or feeding, created from the unique organ located in their back. There are four primary types, with a rare mutation that can result in a specialized fifth kind.
Blade Below the Shoulder: The Koukaku type either wields it like a blade, wrapped around their arm, or simply uses it as a shield.
The protagonist of the series. Kaneki is a first year college student, and after narrowly surviving a Ghoul Attack finds himself transformed into a Human-Ghoul hybrid. He struggles to find a balance between his two natures, and is taken in by the moderate organization Anteiku.
Adorkable: This is even commented on in-verse by some characters who find Kaneki adorable.
Abusive Parents: After his parents died, Kaneki went to live with his aunt. She became jealous that he excelled academically while her own son did not. She started giving him less food and eventually stopped feeding him, merely giving him some money so he could buy his own food. At the start of the series, Kaneki is a college student living alone and seems to have no contact with his aunt.
Adrenaline Makeover: During the timeskip, he develops from a mousy young man prone to wearing pullover sweaters or dress shirts into a confident and aggressive leader prone to wearing all-black combat gear with strategic cutouts. He also buffs up considerably, and gets rid of his medical eye-patch in favor of one with a stylized centipede on it.
Animal Motifs: Kaneki is often associated with centipedes. He even upgrades his eyepatch to one with a centipede pattern. His kagune eventually end up taking a centipede-like form after the events in Kanou's lab, after he goes temporarily goes crazy due to acivating his kakuja for the first time, gained from cannibalizing ghouls.
Anti-Hero: He develops a more ruthless personality after enduring nearly a week of torture at the hands of Yamori, becoming willing to do whatever is necessary to protect the ones he cares about.
Badass: Oh, yeah. Kaneki may have started off weak, but with training and experience, he becomes one of the most dangerous ghouls in the series. When using his half-Kakujya, he's a SS ranked Ghoul.
Badass Bookworm: Although Kaneki lacks the experience that other ghouls have, he is able to quickly process information and creates strategies. At some points, we also see him pull off moves because he studied them so hard from books. After he leaves Anteiku, he has shown to read martial art books to train.
Being Tortured Makes You Evil: Played with. His ordeal leaves him a much more dangerous character, and he starts things off by EATING all of his tormentor's kagune, followed by systematically breaking half of another enemy's bones one by one.
Beware the Nice Ones: His kindness masks a frightening capacity for ruthlessness or brutality, especially after being tortured by Yamori.
Break the Cutie: After the operation, Kaneki's life seems to be a series of traumatic events. Just becoming a Ghoul takes an enormous toll on him psychologically and emotionally, but after he's tortured by Yamori he begins a dark spiral.
Cannibalism Superpower: He began devouring ghouls after the Aogiri arc in order to strengthen his ghoul abilities, which allowed him to become a half-kakuja. Notably, he was able to overwhelm Shinohara, and would have eaten him had he not barely held himself back from doing so.
Character Tic: After bring tortured by Yamori for over a week, he inherits his habit of cracking his fingers right before he gets into a fight. Interestingly, Yamori himself picked up the tic from the man who tortured him and turned him insane.
Clark Kent Outfit: Expected, considering the training that Kaneki has been doing since he became a ghoul. You don't see the results until after the Aogiri Arc. He still looks as scrawny as usual with clothes on.
Cold-Blooded Torture: He endured a week of torture at the hands of Yamori, and since then he's broken half the bones in Ayato's body and threatened Madam A with torture.
Combat Tentacles: He's a Rinkaku type. In his case, his kagune manifests as four tentacles from his midsection, just like Rize. His kakuja Kagune emerge from the same area, but he has six of them and they're shaped and act like centipedes.
Cool Mask: It has one eye exposed (his ghoul eye, as opposed to the eyepatch he normally wears to cover it) and a false mouth that gives him a Slasher Smile until he unzips it.
When using his kakuja, another mask forms over his face. It features an eye-like structure on the middle of his face, between his normal eyes, and it has a jagged beak-like design going downward.
Conveniently an Orphan: His father died while he was still very young, and his mother later worked herself to death attempting to provide
Cruel Mercy/Throw 'Em to the Wolves: After beating Yamori within an inch of his life and devouring his Kagune, Kaneki refuses to finish him off. He instead leaves the other Ghoul weak and vulnerable, with CCG Investigators battling their way through the building and sure to find him eventually. Sure enough, one does eventually find and finish Yamori off in a suitably brutal fashion.
The Dog Bites Back: Quite literally, when he finally broke free and turned on Yamori. He tears off and eats several chunks from the other Ghoul's face, then uses the regained strength to beat Yamori within an inch of his life.
Extreme Doormat: "Better to be hurt than to hurt others". After being told this by his mother, he clings to it as a motto in life and decides it's better to be a victim than to lash out at others. He abandons and completely rejects this notion, once a hallucination of Rize makes him realize his mother's inability to stand up to her sister not only killed her but left him alone.
Eyepatch of Power: He wears one to conceal his Ghoul eye, originally just a plain medical eyepatch. He later begins wearing one with a centipede motif.
Feel No Pain: After being tortured, his pain tolerance has reached such a level that he reacts to most injuries with mild annoyance (at most) as opposed to the usual screaming or crippling shock. He even points out how in comparison, things like a broken leg are nothing.
Genius Bruiser: He is an intelligent, bookish young man but also one of the strongest Ghouls in the series.
Half-Human Hybrid: Half-human half-ghoul, though he became one through a transplant rather than naturally.
Healing Factor: His healing factor goes from above average to exceptional once he starts eating regularly, allowing him to heal broken bones within seconds. This is demonstrated when his leg is twisted around several times, and he simply whips it back around and snaps it back into place.
Heroic Safe Mode: After he's knocked out by Amon in their fight in chapter 133, his Kakujya awakens and the fight continues.
Heroic Willpower: He brought out his kagune for the first time to save Hide from Nishiki.
Heterosexual Life-Partners: Him and Hide. Kaneki especially said, Hide's friendship kept him sane. This is proven when in chapter 136, when Hide meets Kaneki and reveals he long knew Kaneki was a ghoul and doesn't care.
Hunter of His Own Kind: After escaping Aogiri Tree, Kaneki primarily feeds on other Ghouls rather than humans. He does it explicitly to become more powerful, rather than out of any altruistic intentions.
Kill 'em All: After suffering at their hands, he determines that Aogiri Tree must be wiped out entirely.
Laughing Mad: When Yamori puts a live centipede in his ear, Kaneki notes that he can hear someone laughing. After a moment, he realizes that he's the one laughing, having finally gone completely over the edge.
Last Name Basis: Everyone refers to him by his last name, even his closest friends like Hide.
The Mentally Disturbed: His sanity was greatly damaged by Yamori torturing him, as his increasingly brutal actions while cannibalizing other Ghouls takes a massive toll on his mind.
Mistaken For Romance: When going to a book signing with Hinami, he corrects the assumption that she is his girlfriend.
Morality Adjustment: After his torture and resulting acceptance of his nature as a Ghoul, Kaneki begins a slide into Anti-Hero territory, becoming more brutal and ruthless in his efforts to achieve his goals.
My God, What Have I Done?: Several times during the early stages of the series when he nearly does things that would have gone beyond the blurred line that defines ghouls and humans. At one point, he impales Yomo with his arm while in the throes of his hunger, and later on after developing his Kakuja he wounds Banjou and during the attack on Anteiku, he slices off Amon's arm.
Nice Guy: He starts out as a very kind young man, which earns him many friends among Ghouls.
Nice Guys Finish Last: He comes to this conclusion, while hallucinating a conversation with Rize about his mother's fate.
Ship Tease: He has multiple moments hinting at mutual attraction between him and Touka, who warms up to him as time goes by. Their time apart only seems to strengthen the mutual attraction, with Touka dreaming of what she would say to him and him wanting to keep her safe.
Shirtless Scene: When he emerges from the shower in chapter 88, showing off just how buff he's gotten since leaving Anteiku.
Shrinking Violet: Male version. Before the start of the series, he only had one friend due to how shy he was. He later grew out of it.
Terror Hero: As the series goes on, Kaneki is willing to use fear to defeat his opponents.
Took A Level In Bad Ass: He becomes stronger and more willing to fight throughout the series, but the most noticeable jump in awesome comes after being tortured for ten days by the Aogiri. He becomes one of the most dangerous and powerful Ghouls in the setting after that. And becomes far more dangerous after gaining a kakuja kagune after eating other ghouls.
Tragic Hero: From chapter 1, Kaneki was stated to be the protagonist of a tragedy.
Trauma Conga Line: Seriously, Kaneki has horrible luck. First his less-than-stellar childhood, his pseudo girlfriend turns out to be a ghoul and he gets critically wounded that he needs a transplant from her dead body, finds out he's a half-ghoul and has a hard time transitioning...the list could go on and on. It gets even worse for him during the Aogiri arc, where he was systematically tortured for ten days and had a mental breakdown due to it. Can someone give this poor guy a hug?
White Hair, Black Heart: Played with. After being tortured, he emerges with white hair and a greater willingness to commit brutal deeds.
With Great Power Comes Great Insanity: As Kaneki grows stronger, his sanity slowly disintegrates. This started after being tortured by Yamori and then continued as a side effect due to eating Ghouls. When he manifests his Kakuja for the first time, he becomes a rambling lunatic and Shinohara describes him as the most insane Ghoul he has ever met.
A 16-year-old high school student Ghoul working in the local cafe, Anteiku. She is helping Kaneki understand what it means to be one and the thin line between humans and ghouls. She is fascinated by humans, and longs to live a normal life among them as much as possible.
Action Girl: And how. Not only will she kick ass, but she won't hesitate to kill anyone who threaten her friends or risk revealing they're ghouls.
Animal Motifs: She is often associated with rabbits. She is also associated with birds due to her Ukaku Kagune that resembles a wing.
Badass: She can effortlessly outfight common Ghouls, and even more infamous Ghouls like Tsukiyama consider her a dangerous opponent.
Beneath the Mask: She keeps up a mask of cold indifference or hostility, but is actually a very kind girl that longs for a normal life.
Book Dumb: Her grades aren't the best. Though it doesn't help that she never went to elementary school.
Cool Big Sis: Towards Hinami, whom she more or less acts as guardian for. She tried to be one for her brother, Ayato, but it...didn't work out, suffice to say.
Defrosting Ice Queen: She's initially cold and harsh towards Kaneki, but slowly warms up to him over time. She even wants to go with him when he decides to leave after the Aogiri Arc but he encourages her to stay and take her entrance exams so that she can go on to college and keep leading a normal life.
Determinator: Every one of her fights end with her bloody. But she never gives up.
The Dreaded: All Ghouls acknowledge how dangerous Touka is, and even Tsukiyama will admit how terrifying she can be at full power.
Fragile Speedster: Her type is noted to be exceptionally fast, but not very strong or tough.
Freakiness Shame: When Nishiki's girlfriend Kimi sees Touka's kagune, she thinks Touka looks beautiful. Touka, who had just tried to kill Kimi because she knows they're ghouls, runs away wondering how a human could think a ghoul is beautiful.
Genre Savvy: She wears a wig and a hoodie when going after Investigators, helping to conceal her identity. She also knows how to spread false information to help throw them off Hinami's trial.
Good Is Not Nice: As a member of Anteiku, she helps to encourage peaceful coexistence between Ghouls and Humans. However, she's still willing to kill when necessary and can be brutal to other Ghouls.
He Is Not My Boyfriend: Her friend Yoriko thinks Kaneki is her boyfriend/the boy she likes when she sees them together. Touka is not amused.
Hot-Blooded: Her icy disposition belies a fierce temper and passionate heart. She's all smiles when dealing with customers at the cafe, but will quickly get annoyed and insult others who she cannot stand. Kaneki is on the receiving end of most of it. This facet of her personality is responsible for the final event that brought the doves over to the 20th ward.
I Just Want to Be Normal: She wants to experience everything in the human world like a normal girl, despite the threat of being revealed as a ghoul.
I Will Wait for You: After Kaneki refuses to let her come with him at the end of the Aogiri Arc, she decides to wait for his return to Anteiku, although she's deeply resented from his drastic change of personality and leaving her behind. At the end of the series, she's still waiting for him, even though there isn't an Anteiku to return to anymore and it's unclear whether Kaneki is still alive.
Jerk with a Heart of Gold: She is rude and aggressive to Kaneki at first. But was kind enough to stop Kaneki from eating Hide when Kaneki when insane with hunger.
Nice Job Breaking It, Hero: She took revenge for Hanami's mother, but in doing so she killed the wrong CCG agent and caused the organization to turn their attentions to the 20th ward, instead of letting the murder go and avoid their attention in the first place.
Not What It Looks Like: Twice with Kaneki. First, when Touka lifts Kaneki's shirt to check his muscles after training, Uta just happens to walk in. The other time is Yoriko finds Kaneki in Touka's apartment.
Peek-a-Bangs: Her bangs typically conceal her right eye, visually signifying she is an individual who has something to hide.
Ship Tease: She has considerable hints of mutual affection with Kaneki, who she warms up to and begins to show great concern for. She is willing to abandon her efforts at a normal life for him, and during their time apart she dreams up multiple scenarios of what she would say to him.
She's Got Legs: She has long, pretty legs and a lot of her clothing shows this off. Especially in the anime.
Shorttank: The tomboyish female lead who constantly gets angry at the main character, but likes rabbits.
Speed Blitz: She's so fast she can carve up her opponent with dozens of cuts in the blink of an eye.
Tsundere: She is typically brash, rude, and violent, demonstrated in her first encounter with Kaneki. However, she does warm up to people and she is shown caring about others such as Hinami and her human friend Yoriko. She even forces herself to eat the food Yoriko gives her because it makes the other happy despite the fact that it tastes terrible to ghouls and even makes them ill.
Uncanny Family Resemblance: She looks just like her brother, Ayato. So much so that when Banjou first met her, he thought she was Ayato.
A sweet girl with a fondness for books. However, under her charming personality and appearance she is known as "Binge Eater" Rize, a well-known Ghoul that terrorized several other wards before moving to the 20th ward. Her kagune is started to be extremely powerful and unique, making her a much-sought after target by multiple groups.
Badass Bookworm: It seems that she liked reading and was reading the same book at Kaneki when he asks her out on a date. Tsukiyama also mentions that she liked to read and many chanters comment on the fact that she was one of the strongest ghouls. She was in fact able to take over the feeding grounds of several ghouls in the 20th district.
Big Eater: She's a ghoul known to eat humans more often than necessary, hence the moniker 'Binge Eater' Rize.
Bitch in Sheep's Clothing: She initially seems like a shy and modest girl but that personality turned out to be a ruse in order to seduce Kaneki. She then proceeds to try and eat him.
Boobs of Steel: She was stacked and has been repeatedly stated to be a very powerful ghoul.
Combat Tentacles: She has four that emerge from her back, and she's quite good at using them to play with her food.
Cute Bookworm: Invoked. Coupled with her great fondness of books, she showed a shy and cute personality to seduce her victims just like she did with Kaneki.
Damsel in Distress: Banjou sees her as this and comes looking for her in the 20th ward because he thinks that she's in danger. We later find out that she really is in danger. The beams that crushed her at the beginning of the series did not kill her and since that time she's been kept by Dr. Kanou as a means to create more ghouls. When we finally see her alive, she is powerless.
Dark Action Girl: Rize is implied to be this at the beginning of the series. She is stated to have thrown several wards into chaos before moving on to the next. Her killing of the strongest Ghouls in District 11 allowed Aogiri to move in and take over.
Femme Fatale: Known for using her beauty to lure in men. Interestingly though, she didn't play up her sexuality and instead projected a "shy girl" persona to lure in men. It worked too since that's what attracted Kaneki to her. Presumably, he wasn't the first guy to fall for this.
Floral Motifs: The Red Spider Lily, traditionally associated with Death and Abandonment or Loss. Her kagune are represented by these flowers in the opening, while her appearance to Kaneki in a vision prompts the flowers to begin appearing around them.
It Amused Me: She lived solely for her own enjoyment, doing things to ease her boredom.
It's All About Me: She's incredibly selfish and doesn't care about how her actions affect others.
Manic Pixie Dream Girl: Banjou seems to have viewed her as this, while everyone else recognized the damage her selfish actions caused to everyone around her.
Meganekko: She played this trope up, coming across as sweet and demure prior to revealing her true nature.
Ms. Fanservice: She's pretty, has big boobs and even had a shower scene. Her first appearance in the anime even had her naked.
Not Quite Dead: Although initially it seemed like the beams definitely crushed her, it is later revealed that she is not dead and is being kept alive to create more half ghouls. She is found half starved in Kanou's lab. However, she's barely even a shell of the person she used to be, as both her eyes are missing, she may not have any kagune left, and all she can do is eat.
Posthumous Character: She dies fairly early in the series, but is referenced to by several characters. It also seems that she was specifically killed so that her body could be used to turn humans into ghouls.
Purple Is Powerful: Her hair, eyes, and accents in her clothing are purple. She's noted to have been an exceptionally powerful Ghoul, with unique Kagune that made her the target of more than one party.
The owner and boss of the ghoul cafe, Anteiku. He is an advocate for peaceful relations between Humans and Ghouls, and is noted for reforming many violent young Ghouls over the years. Though kind and wise, his long lifespan is evidence that he is an exceptionally powerful Ghoul. His past is shrouded in mystery, with many secrets that continue to haunt him.
Animal Motifs: The Owl, a bird typically associated with wisdom. He is the second Owl, having impersonated the original to protect his child.
The Atoner: In his youth, he was a brutal Ghoul that preyed on humans and Ghouls alike. He came to serve an organization that employed him as a "Cleaner", murdering humans and Ghouls that caused them problems. However, when his human lover turned out to be a reporter investigating the organization, he was forced to kill her and abandon their Half-Human Hybrid child in the 24th Ward. Since then, he has worked to reform other violent Ghouls and offer a peaceful alternative to killing humans. He even posed as the One-Eyed Owl in order to cover for his child.
Badass: It's noted any Ghoul that lives to old age has to be incredibly strong, and he's able to take on multiple Doves in battle by himself. He is one of the most powerful Ghouls in the series, holding an SSS rating.
Badass Boast: He gives a great one when the CCG invade the 20th ward
"The act of taking life is equally evil. We from the moment of birth continue to take. Food. Connections. Even fellow blood. Living to the utmost. Continuing to slaughter, kill, take. Life is the constantly sin. Life is evil itself. I am aware I am evil. And so are all of you. Now. Come and kill me. And I shall do the same!"
Retired Badass: He has settled into a quiet life running his cafe, and managing the affairs of the 20th Ward with a gentle hand. He rarely has to exercise more than a stern presence,
Big Damn Heroes: He jumped between Yomo and Arima just when Airma was going to kill Yomo, many years ago
Big Good: As the leader of Anteiku, he seeks to promote a more peacefully Ghoul society and co-existence with humans. He is noted to have taken over the 20th ward and divided territories between the Ghouls there, as well as his tendency to take violent Ghouls under his wing and rehabilitate them.
Cannibalism Superpower: In his youth, he devoured other Ghouls. As a result, he has developed a Kakukja-type kagune that provides him with armor.
Cool Old Guy: He is the ever-wise, unflappable manager of Anteiku and makes a habit of taking wayward young Ghouls under his wing.
Lightning Bruiser: Perhaps the greatest example within the series. Being an Ukaku type, he has incredible speed and the ability to fire off projectiles with strength compared to a shotgun. Unlike most Ukaku, though, he is also tough enough to face two Special Investigators with specialized S-class equipment without taking damage.
Love Redeems: His change from remorseless killer to the head of Anteiku started when he fell in love with a human woman.
Monsters Anonymous: Anteiku has been set up as a haven for Ghouls that attempt to live peacefully with humans, providing food for those that cannot bring themselves to hunt.
Papa Wolf: Though forced to abandon his child, he remains fiercely devoted to keeping them safe through whatever means necessary. This includes impersonating the Owl in order to carry out a third attack on CCG, and dooming Anteiku rather than give his child up to his former superiors.
The Red Baron: Owl, though only because he impersonated his child to throw off the trail.
Star-Crossed Lovers: With Ukina. When Ukina was exposed as a reporter investigating the organization he served, they forced him to kill her.
Swallowed Whole: His daughter does this to carry him to safety, and spits him up once she's escaped pursuit.
Vegetarian Vampire: Anteiku's food supply comes from scavenging dead humans, typically suicides from the nearby mountains.
A young man with an eccentric personality and taste to match it. He is known as the Gourmet, and models his feeding off high-class dining with a focus on "interesting" or unique victims. After meeting Kaneki, he becomes obsessed with him.
Abhorrent Admirer: To Kaneki. He is fascinated with the other because Kaneki is a one eyed ghoul and wants to eat him. After the Aogiri arc he seems even more infatuated with the other due to the fact that Kaneki has become stronger and more ruthless.
Agent Peacock: He may look like a ridiculous fop, but don't be fooled - he's one of the most influential and physically dangerous ghouls in Ward 20.
Angst Coma: After failing to prevent Kaneki from going to his apparent death, he is seen laying there listlessly while Nishiki watches over him.
Autocannibalism: This is how he survives his battle with Kaneki and Touka. While they think that they left him for dead, Tsukiyama in fact ate his own flesh in order to regain the strength to leave the church. He notes that he tastes delicious.
Bishōnen: He's extremely handsome and well-dressed, playing up his good looks with fashionable clothing and a stylish haircut.
Blade Below the Shoulder: His kagune is wielded like this, with it typically wrapping around his arm so he can use it like a sword.
Camp: At first his habit of posing crazily played up to accentuate his insanity. Later on, when he becomes less of a threat, it becomes more comedic.
Combat Pragmatist: He proposed an alliance with Naki when the Doves arrived at the lab, but secretly plans to finish him off once he's exhausted.
Cool Mask: A crescent moon-shaped mask, themed after the Man in the Moon.
Crazy Jealous Guy: He considers anyone attempting to eat or otherwise harm Kaneki to be a serious offense, flying into a rage.
Depraved Bisexual: Played with. While his interests in his targets appear to be sexual, its only to the extent of valuing them as food. Kaneki seems to be main target of his unwanted affection although he has shown interest in Touka and Kimi as well.
Does This Remind You of Anything?: Nobody will blame you for seeing some homoerotic undertones in his behavior and how he gets close to Kaneki. There's also his rather blatant victim blaming of Kaneki, claiming that everything is his fault for being too irresistible; this is the same sort of logic rapists and rape apologists use.
The Hedonist: He derives a lot of pleasure from experiencing different flavors. And the only reason he starts to help Kaneki is for the chance to try the other's flesh, something Tsukiyama believes will be the ultimate experience.
Heel-Face Turn: Played with. He helps rescue Kaneki from the Aogiri and joins him in his journey to eliminate more dangerous Ghouls and track down the man who turned him into a hybrid. However, his response to seeing how much Kaneki has changed is distress upon realizing how much more difficult it will be to eat him now.
Hoist by His Own Petard: Because he is obsessed with Kaneki, he becomes instantly distracted from his surroundings when he sees Touka bite the other. His clothing also turns out to be impractical for combat since Nishio grabs onto his tie and holds him in place long enough for Touka to take out Tsukiyama's face and arm.
In Love with Your Carnage: His obsession with Kaneki grows after the Aogiri arc once Kaneki becomes even more deadly and cold hearted. He is delighted when Kaneki issues him a death threat.
Interplay of Sex and Violence: In a show where the strange intimacy of cannibalism is repeatedly drawn attention to, this guy proceeds to completely dispense with the subtlety. His attempts to groom Kaneki to be the perfect meal and his delighted anticipation of that moment (complete with Perverted Sniffing of a stolen handkerchief) read more like something out of Humbert Humbert's playbook than Hannibal Lecter's.
Large Ham: He is melodramatic to the extreme, shouting foreign words and posing bizarrely as though an actor on the stage.
Obsessed with Food: He is obsessed with fine dining and finding the right "parts" to turn into meals. In his first appearance in the manga we see him steal a woman's eyes to turn into a meal because he thought they were beautiful. He also participates in an underground restaurant that lures humans to become entertainment and food for ghouls.
Narcissist: He is incredibly self absorbed and arrogant but also very obsessed with appearances. He disliked Rize for the fact that she didn't care about the appearance or quality of her meals and that she indiscriminately ate humans.
Perverted Sniffing: He has a handkerchief with Kaneki's blood on it and seems to enjoy the taste and smell of it a little too much... We later see that he keeps it inside a plastic bag to preserve the scent and seems to periodically be smelling it because it's as close to eating Kaneki as he's going to get.
Picky People Eater: He only takes the eyes of a beautiful young woman after complimenting them. This also serves to contrast him with Rize. While Rize will eat mostly anything, Tsukiyama will only eat specific people. His obsession with Kaneki comes from the way the other smells and the rarity of being a one eyed ghoul. Their differences is also why Tsukiyama actually disliked Rize despite giving Kaneki the impression that they were friends.
Psychopathic Manchild: He acts very mature most of the time and seems to have very high class tastes. However, he also is prone to fits of anger and jealousy. He throws tantrums such as during his fight with Touka in which he loses it when she takes a bite out of Kaneki. He starts screaming at her that Kaneki belongs to him. He can be childish and unreasonable when he doesn't get what he wants.
The Only One Allowed to Defeat You: A variation of this. He joins a rescue mission to save Kaneki during the Aogiri Arc not because he cares about the other, but because he still seeks to devour him.
Red Baron: The Gourmet, a title earned due to his dining habits. Within the Ghoul Restaurant, he was known as "MM".
Sissy Villain: Apart from the tiny detail that he wants to fillet Kaneki rather than bone him, he's a walking Camp Gay stereotype.
Stalker Without A Crush: He randomly shows up at Kaneki's school in order to have a chance to talk to him privately and smells the handkerchief with his blood. And after the Aogiri arc it seems that he's doing everything he can to stay close to Kaneki and even becomes an official member of Kaneki's group. But its all so he can eat him.
Token Evil Teammate: After the Aogiri arc, he decides that if Banjou is to become Kaneki's "shield," then he will become Kaneki's "sword." He becomes a member of Kaneki's crew but still has the intention of eating the other. Kaneki even warns him not to step out of line or he'll kill him.
Wicked Cultured: He seems to be able to speak multiple languages or at least know phrases in other languages. He shares a strong interest in literature with Kaneki and Rize and knows a lot about high class culture. Rize calls him out on this. She finds it amusing that all these things and his obsession with the taste of his food make it seem like he's trying to act like a human rather than a ghoul. This is what really makes him start to hate her despite wanting her to become a part of his dining club.
Worthy Opponent: He pretends to extend this towards Naki, who in turn considers him a "decent guy".
Yandere: Toward Kaneki since the moment he met him. He became fascinated with the other because of his unique scent and this later turned into an obsession once he realized that Kaneki was a one eyed ghoul, making him incredibly rare.
A ghoul from the 11th Ward, and former associate of Rize. He comes to the 20th Ward in search of her, and has lingering feelings for her. Though a pacifist, he as a strong sense of duty and becomes one of Kaneki's allies.
Cowardly Lion: He's noted for being the biggest chicken around, frightened by Ghost stories and horror movies that he watches with Hinami. But when it comes to the people he cares about, he'll leap into the fray without a second thought.
Dogged Nice Guy: He is arguably one of the nicest ghouls in the series. He is also hopelessly in love with Rize, who doesn't care about him at all.
The Dulcinea Effect: He puts himself at risk by going to the 20th Ward to warn Rize that she might be in danger despite the fact that he hardly knows her and it's very clear that she won't return his affection. It's also clear that Rize is incredibly selfish and doesn't care about how her actions affect others. It becomes apparent that Banjou has an idealized image of her.
Healing Factor: Unlike most Ghouls, his Kagune seems to be used exclusively to heal his injuries.
Heroic Sacrifice: Attempt when he threw himself between Kouto and one of the Bin Brothers and then forced the rest of the Anti-Aogiri group to leave. He survived because Kaneki and the gas mask brothers came back for him.
Honor Before Reason: Regardless of his weakness and peaceful nature, he readily places himself in harm's way for the sake of others.
Hopeless Suitor: He harbored feelings for Rize, even after she called him a "boring guy".
Hot-Blooded: He's a passionate guy, and this leads to an initial confrontation when he mistakes Kaneki as Rize's boyfriend.
The Leader: He was the leader of 11th ward after Rize left, but was defeated when Aogiri Tree arrived.
Love Makes You Dumb: His feelings for Rize completely blind him to the fact that she's a terrible person who doesn't care about anyone but herself. She is incredibly selfish and causes problems for other ghouls in the 11th ward by attracting the attention of CCG as well as destabilizing the area. He even goes to the 20th ward to find her despite knowing that he'd incur the wrath of the Aogiri Tree.
Nice Guy: Perhaps one of the kindest characters in the series. While he lacks strength, other Ghouls willingly follow him because he genuinely cares for their well-being.
Non-Action Guy: Despite his best effort, Banjou is pitifully weak. He can't even use his kagune, so his only advantage is that he's heavily built.
A young Ghoul who is a second year in Kamii University, and an upperclassman to Hide and Kaneki. Before the start of the series, his hunting territory was overtaken by Rize and his efforts to reclaim them place him at odds with Kaneki. He has a human girlfriend, and his devotion to her slowly leads him to change his ways.
Black Eyes of Evil: Inverted. His eyes appear completely black, at the moment when he realizes his feelings for Kimi.
Character Development: He's introduced as a petty and selfish Ghoul who's willing to kill other Ghouls who simply interlope on territory he deems to be his, but has yet to actually (re)claim. He also nearly murders both Kaneki and his human best friend. Later on, he winds up realizing the error of his ways and joins the gang at the coffee shop.
Cynicism Catalyst: He had an older sister, but she was killed after a human she trusted reported her as a ghoul. Nishio then killed the guy who reported her and decided never to trust anyone. That was until Kimi found out he's a ghoul and she accepted him instead and even offered him to eat her, showing him that there are humans you can trust.
Determinator: When his human girlfriend, Kimi, is kidnapped by Tsukiyama. Even starving and badly injured, he just won't give up no matter how much punishment he receives.
Heel-Face Turn: He eventually becomes one of Kaneki's allies, after receiving help from him.
Heroic Resolve: Every single time Tsukiyama threatens Kimi, he manages to find the strength to get back up.
Interrupted Intimacy: Hide and Kaneki walk in on him during a very hot-and-heavy session with his girlfriend, who runs out shrieking. He later asks them (for Kimi) how much they actually saw.
Interspecies Romance: He has a human girlfriend, as evidenced when Kaneki and Hide walk in on them getting hot and heavy.
Jack of All Stats: His kagune type is described as such, being far more balanced than the other types that specialize in either speed, strength, or regeneration.
Jerk with a Heart of Gold: He's rude and condescending towards others, but he also genuinely loves Kimi to the point of starving rather than harm her. After Kaneki helps him, he returns the favor and feels the need to repay his debt.
Love Redeems: He risks everything to save Kimi, and gives up on hunting humans for her sake. That Kaneki helped save Kimi leads him to become an important ally, feeling indebted to him.
The Masquerade Will Kill Your Dating Life: In light of CCG raiding Anteiku, he states his intentions to see Kimi one last time before disappearing. It isn't clear yet whether he'll actually go through with it, but staying with her certainly puts her life at risk if they're caught.
Megane: Reference his aloof demeanor. He started wearing glasses as a teenager.
Non-human Lover Reveal: He nearly attacks Kimi when she comes to check on him, revealing himself as a Ghoul. He's unable to kill her, and she willingly keeps his secret.
Tail Slap: His kagune resembles a blue glowing tail, and investigators discussing different Kagune types describe it as a "trump card".
Used to Be a Sweet Kid: When he was very young, he hated having to kill humans in order to survive. His sister did all of the hunting for him.
A stoic man that serves as Yoshimura's right-hand man, carrying out odd jobs for Anteiku. He was once a violent thug, but has been reformed into a wise man of few words. Along with Touka, he provides guidance to Kaneki on life as a Ghoul and teaches him how to defend himself.
Animal Motifs: Birds, particular carrion birds such as crows and ravens.
Arch-Enemy: He hates Arima, as Arima killed his older sister, the last family he had left.
Badass: He is probably the second strongest character affiliated with Anteiku, behind Yoshimura.
Badass Longcoat: He wears a large coat, covering his massive frame from neck to shins.
Retired Badass: He and Uta made the 4th ward practically impossible to live in back when they were younger due to their fighting.
Cool Mask: It resembles a gas mask with a long beak much like the masks worn by Plague Doctors.
Super Senses: She's noted to have exceptional senses, even by Ghoul standards. Unlike most Ghouls, she recognizes that Kaneki's scent is strange and her hearing is good enough to detect what is going on elsewhere in a large building.
Sword over Head: After badly injuring Mado, she ultimately decides not to avenge her parents by killing him.
Trauma Conga Line: She loses her mother, sees a Dove using her mother's stolen kagune as a weapon against Ghouls, nearly gets killed, and soon finds herself mixed up in all of the dark conspiracies Kaneki and co are pulled into.
Winged Humanoid: Her second kagune resembles a moth's wings, though they aren't wings so much as large shields for defense.
Wise Beyond Her Years: She shows occasional glimpses of wisdom, realizing that revenge won't change anything and later recognizing that Kaneki was not well after his ordeal.
A gentle and kind-hearted ghoul, and the mother of Hinami. She sacrificed herself to protect Hinami from Investigators, and was killed by Mado and Amon. After her death, Mado would use her kagune in tandem with her husband's stolen kagune.
Barrier Warrior: A Kouhaku type, she uses her kagune primarily for defense. Mado modifies them into a shield after her death.
Heroic Sacrifice: She faces down four Investigators on her own, all to give Hinami a chance to survive.
Mama Bear: Though gentle, she fights fiercely to protect her daughter.
Sacrificial Lamb: Her death served to show the cruel reality for Ghouls, hunted and slaughtered even when they tried to live peacefully with humans.
Technical Pacifist: Her husband and later, Yoshimura, provided her with food because she could not hunt. Only when her daughter is in mortal danger does she fight, but even then only to distract the investigators long enough for Hinami to escape.
Winged Humanoid: Her kagune resemble four flower petals, sprouting from her back like a butterfly's wings.
You Shall Not Pass: She does everything in her power to prevent the investigators from chasing Hinami.
A member of the Ghoul Restaurant known as "Madam A", and the owner of several "Scrappers". She was living in poverty, jealous of the well-off Ghouls until Dr. Kanou offered to let her take charge of his failed experiments.
Chekhov's Gunman: She originally appears as a member of the Ghoul Restaurant, but is later tracked down by Kaneki's group when it turns out she knows Dr. Kanou.
Eat the Rich: She thinks that wealthy people probably taste better.
Green-Eyed Monster: She's extremely resentful of those well-off and able to enjoy the good life.
Mock Millionaire: She pretends to be wealthy and powerful, but she's actually living in humble conditions and stuck handling Dr. Kanou's castoffs.
The Red Baron: "Madam A", the alias she uses at the Ghoul Restaurant.
What Happened to the Mouse?: She's last seen fleeing when Aogiri members interrupt the search of Dr. Kanou's underground lab. It isn't clear whether she escaped, or ran into the Doves that showed up later.
The father of Touka and Ayato Kirishima, a pacifist Ghoul that encouraged his children to coexist with humanity. He lived with his family in a human community and scavenged the corpses of humans and Ghouls to survive. This caused him to become a Kakuja, and earned him the title "Corpse Collector". He was eventually tracked down by Shinohara and Mado, and killed by them. His kagune would be used to develop CCG's quinque armor bearing his name.
Super Prototype: His remains were used to create one, worn by one of the investigators that killed him.
Technical Pacifist: He did his best to refrain from harming others, scavenging the corpses of the dead for food.
Van Helsing Hate Crimes: He did his best to live peacefully with humans, but was shown no mercy by the Investigators.
The One-Eyed Owl
A legendary Ghoul that slaughtered numerous Investigators a decade ago, and remains at large. Little is known about it, other than its unimaginable power and hatred for the world. It is rumored to have come from the 24th District, and may be connected to the leader of Aogiri Tree. For more information, see Secret Identity.
Ambiguous Gender: The Owl is a mysterious being in a massive cloak, with layers of Kakuja armor sticking out. As such, it's impossible to distinguish if it is male or female.
Samus Is a Girl: The Owl is a petite young woman, able to pass herself off as a child when she's dressed as Eto.
Antagonistic Offspring: She's actually Yoshimura's child and an executive of Aogiri Tree, Eto. In the final chapter, it's revealed she captured him, presumably for future ghoul experiments Kanou will conduct in his new lab.
Arch-Enemy: Both Kureo Mado and his daughter, Akira, want to kill it for personal reasons. Mado's wife held it back to let others escape, and was brutally killed in the process. The Owl itself seems to consider Arima this, expressing excitement when the Investigator that once wounded it appears.
Badass: It is the most powerful Ghoul ever recorded, and killed an incredible number of Investigators prior to being driven off.
Cannibalism Superpower: Noted to be one of the rare Kakuja types, meaning that it gained power by eating other Ghouls.
Cyclops: A distinct feature of its Kakuja mask, giving it the appearance of only having one massive eye in the center of its face.
Daddy's Girl: She is ecstatic after meeting her father, in spite of him abandoning her. In turn, Yoshimura is completely devoted to keeping her safe regardless of her crimes.
The Dreaded: The very thought that it might show up results in CCG shutting down the 20th Ward and bringing in everything they have.
Hero Killer: It earned its reputation by killing almost everyone that encountered it. When it shows up again, it tortures and then mortally wounds Shinohara.
Instant Armor: Kakuja armor functions this way, and the Owl takes it to extreme lengths.
Living MacGuffin: Both CCG and the mysterious Organization "V" are looking for it.
Monstrous Humanoid: Its Kakuja form is enormous and barely human in appearance, showing just how far the mutation can take a Ghoul.
Naked on Arrival: Emerges from her armor completely naked, but quickly wraps herself up in part of her cloak.
Nigh Invulnerable: Most enemies can barely scratch Owl's armor let alone inflict bodily harm.
Ominous Owl: The most infamous Ghoul on record, and pretty disturbing to look at in person.
Parental Abandonment: Yoshimura was forced to abandon her in the 24th Ward, in a desperate attempt to protect her from his former superiors.
Razor Wings: Owl's Ukaku wings can slice through just about anything, demolishing flesh and quinque with little effort.
Secret Identity: Eto, one of Aogiri Tree's executives. She's also Sen Takatsuki, the horror novelist admired by Kaneki.
Shrouded in Myth: It is legendary among both CCG and the Ghouls, for the sheer amount of carnage it left in its wake.
Slasher Smile: It's default expression, made all the more disturbing by its Kakuja mask.
Super Speed: Owl moves deceptively fast for its size. Surviving more than a few seconds without being torn to shreds is quite a notable accomplishment.
Swallowed Whole: Uses a nonlethal variant to rescue her father from the CCG, vomiting him back out when they've safely escaped.
Walking Spoiler: Once the Owl begins to emerge from myth into the actual story, the spoilers come fast and hard.
An organization of Ghouls, that has taken over the 11th Ward. Their leader is a legendary Ghoul known as the One-Eyed King, surrounded by rumors and myths. They are the primary antagonists of the story, targeting both Kaneki and the Ghoul Investigators.
Anti-Human Alliance: CCG takes note of them as the largest and most organized group of Ghouls ever known, united by their hatred for humans.
Fantastic Racism: Noted to be a militant group defined by their belief in the superiority of Ghouls, and general disdain for the weakness of humanity.
Evil Overlord: He seems to be one, ruling over Aogiri Tree with an iron fist while remaining unseen by all but his closest executives. When discussed, the imagined image of him is a skeleton resting on a throne.
Half-Human Hybrid: His title suggests he may be another Ghoul-hybrid, just like Kaneki.
Secret Identity: Eto is actually the One-Eyed King, but pretends to merely be a subordinate. Her human identity is Sen Takatsuki, the horror novelist with many Ghoul fans.
Shrouded in Myth: Multiple rumors and legends circle about the King, with little concrete information.
The One-Eyed King's right hand man, a ruthless and proud Ghoul. He has little tolerance for weakness, and quickly discards Kaneki as useless. He is almost always with Eto.
Bishounen: He's notably very handsome, especially when compared to the likes of Yamori.
Cold-Blooded Torture: Off-panel, he interrogates Dr. Kanou's assistant about where the doctor is hiding, and later emerges carrying her severed foot. No details are given, but Naki's comments suggest torture as involved in the process of gaining information.
Cool Mask: He wears one over the lower half of his face.
The Dragon: He is the second-in-command of Aogiri Tree, and is stated to have exceptional fighting strength.
Man in White: He cuts an eerie figure in his all-white clothing, with his white hair and red mask as the only contrasting element.
Nice Job Fixing It, Villain: His decision to toss aside Kaneki ultimately leads to him becoming one of the strongest Ghouls in the story, with a serious grudge against their organization. Eto even points out that Tatara should have just killed Kaneki, instead of leaving the chance for him to develop into a threat.
The Social Darwinist: He apparently has no use for anyone he views as weak, and quickly tosses Kaneki away upon deciding that he isn't strong enough for their purpose.
Those Two Bad Guys: Hinted at, with Banjou explaining to Kaneki that Tatara and Eto frequently work together as opposed to the other, more independent leaders of Aogiri Tree.
White Hair, Black Heart: A handsome and utterly ruthless man with white hair. He shows no patience or sympathy for others, writing Kaneki off very quickly as useless.
One of the executives of Aogiri Tree, usually seen with Tatara. A child-like Ghoul of unknown gender, Eto is covered in bandages and possesses knowledge of many important secrets.
Ambiguous Gender: Due to being covered in bandages, it isn't clear what Eto is. Later revealed to be female, when it turns out that Eto and Sen Takatsuki are the same person.
And Show It to You: Tears out several of Banjou's ribs, doing it so quickly that the other Ghoul only realizes he's been wounded when shown the bones.
Antagonistic Offspring: Kaneki suspected that Aogiri's leader was Yoshimura's child. Actually it was more complicated than that. While Eto is revealed to be his daughter and she is a member of Aogiri Tree, she comes to her father's rescue and seems absolutely delighted to see him. However, it seems that she intends to use him for the second stage of Dr. Kanou's experiments in creating artificial One-Eyed Ghouls like her.
Badass: Able to tear through multiple powerful opponents with ease, and holds one of the highest ranks among the Darwinian organization Aogiri Tree.
Badass Bookworm: She's an accomplished author, but also the deadliest Ghoul on record.
Bandage Mummy: An utterly terrifying example, that only makes Eto look creepy.
Chekhov's Gunman: She is the One-Eyed Owl, the half-human child of Yoshimura being sought by multiple organizations.
Compressed Hair: The combination of hood and bandages probably help, but still she's got quite a lot of hair to neatly hide under them. When we first meet her as Takatsuki, her hair is a waist-length bushy mess.
Creepy Child: Seemingly, as Eto has a small and child-like build.
Flash Step: Possessed speed sufficient to almost appear to be teleporting, using this to great advantage.
Foreshadowing: Her right eye is the only one ever given any detail, hinting that she's another One-Eyed Ghoul. When her face is finally shown, her left eye remains normal.
Killer Rabbit: The tiny child-like Ghoul wearing a pink floral scarf seems like the least dangerous member of Aogiri Tree, right up until bones are being torn out before their owners realize it and Eto is dancing circles around the Twins without even trying.
Super Speed: Displays speed far beyond any other Ghoul, easily out-maneuvering the twin sisters and taking down Banjou before he'd even realized Eto was there.
Those Two Bad Guys: Hinted at, with Banjou suggesting that Tatara and Eto operate together most of the time.
We Have Reserves: Subverted. Though their plan required half their forces to act as decoys, afterwards Eto asks how many of their comrades ended up falling in battle and seems displeased at their deaths.
The other direct subordinate of Aogiri's Leader, a massive man that rarely speaks. He displays regenerative abilities far beyond the norm for a Ghoul, and is noted for his enormous appetite.
Badass: He's one of the top members of Aogiri for a reason, able to fight Yomo, Uta, and Tsukiyama at the same time.
Big Eater: It's noted that he eats an absurd amount of food, compared to other Ghouls.
The Brute: His defining trait is his brutality and strength, acting as the other primary agent of the One-Eyed King.
Combat Tentacles: His kagune are a pair of tentacles ending in hideous smiling mouths, used to tear his victims to pieces.
Cool Mask: A seemingly-eyeless mask with a giant smile as its main feature.
Evil Redhead: This ruthless Ghoul has extremely dark red hair, looking almost black in most light.
Eyeless Face: His mask gives this appearance, with no obvious place for him to see out.
Healing Factor: Far beyond the norm seen by other Ghouls, allowing him to regrow his head during a battle.
The Voiceless: As an executive of Aogiri, presumably he can speak. But he's never said anything on panel, adding to his intimidating presence.
Yakumo "Yamori" Oomori
Voiced by: Rintarō Nishi
One of the executives of Aogiri Tree, famed as "Jason of the 13th Ward". He is a brutal sadist that enjoys torturing other ghouls for his personal amusement.
Ambiguously Gay: After his death, more than one former associate has made comments suggesting he had questionable relationships with them.
Badass in a Nice Suit: He always wears a three-piece suit, with the jacket and slacks white for bonus points. He removes the jacket, pins up the sleeves, and wears an apron when indulging in his....hobby.
Being Tortured Makes You Evil: It isn't clear what his personality was like prior, but after his imprisonment and torture he emerged a brutal sadist. He describes the moment the torture drove him insane, and how he took on his tormentor's personality to survive. After Kaneki is tortured by him and escapes, he begins to take on Yamori's Character Tic and personality traits.
Big Brother Mentor: He's viewed this way by Naki, who even refers to him as "Big Bro". It's....questionable how much he actually was to the younger Ghoul, though.
Exact Words: He reassures Kaneki that he never tells "boring lies". When Kaneki later calls him on lying, he invokes this trope by pointing out he's having too much fun for it to be a boring lie.
Expy: An in-universe example. His name came from Investigators being reminded of a certain Hockey mask-wearing murderer related to the number 13...
Foil: To Juuzou. Both are associated with the number 13, and both became sadistic monsters as a result of extensive abuse suffered at the hands of the opposite species.
Freudian Excuse: He was taken to a Ghoul Detention Center sometime in the past, and handed over to an interrogator in hopes of getting information from him. His interrogator was sadistic and completely out of control, subjecting him to torture that finally drove him insane. He emerged from his captivity having taken on his tormentor's personality, and became the brutal killer known as "Jason".
A pair of siblings that are executives of Aogiri Tree, always acting in unison. They are strong believers in the supremacist beliefs of the organization, and deeply loyal to the One-Eyed King. They were slain in battle by Amon during the raid on the 11th Ward.
Attack Pattern Alpha: The brothers fought in unison, using different attack patterns assigned numbers.
Badass: Powerful enough to be S-ranked, and among the top leaders of Aogiri Tree.
Sibling Team: It isn't clear if they're twins or simply an older and younger brother. But they are a lethal team, either way.
Spin Attack: Several of their moves involve doing so, partially to build up force and partially to confuse their targets.
Tail Slap: Their primary method of attack, being Bikaku types.
Undying Loyalty: To the One-Eyed King. They are noted among the leaders of Aogiri for their exceptional devotion to the cause.
A member of Aogiri Tree, originally held prisoner in the Ghoul Prison. He is Yamori's right-hand man, and imitates his "Big Bro" in every way possible. He shows extreme signs of emotional instability, and isn't particularly bright.
Badass in a Nice Suit: He wears one to imitate Yamori's look, and complains when extending his Kagune damages his clothing.
Blade Below the Shoulder: He wraps his kagune around his arm to wield it like a sword, the same technique used by Tsukiyama.
Character Tic: He cracks his fingers, just like his beloved "Big Bro".
The Ditz: He's prone to mishearing words, and behaves in a childish fashion.
Evil Counterpart: An eviler counterpart to Tsukiyama, being a powerful Ghoul that wields his kagune like a sword and has an unhealthy obsession with another Ghoul. The two duel on more than one occasion, and express a mutual respect for each other.
The doctor who performed the operation that transformed Kaneki into an One-Eyed Ghoul. While initially he seems innocent, in truth he has his own plan and has strong ties to Aogiri Tree. Though he left them in the past, when located by them he chooses to side with them to continue his research.
Above Good and Evil: He views himself this way, at least. He knows his research will be viewed by others as evil, but believes his work transcends normal standards of judgement.
Bad Samaritan: During Kaneki's operation, we see that he is dedicated to saving the other's life despite not knowing him. He even breaks hospital policy and operates without notifying Kaneki's family. Later, we see that he treats Kaneki kindly and seems worried about his overall well being. This is because he wanted to use the other to create a one eyed ghoul. He was also involved in the accident that incapacitated Rize so that he could use her organs in his experiments. Since he also considers Kaneki his "ultimate creation", he wanted to check his development and gain his trust.
Bitch in Sheep's Clothing: He presents himself as a kindly doctor when in reality he's running illegal experiments on humans and doesn't even seem to care about how his actions hurt others.
Evil Plan: Kaneki's transformation into a ghoul was no accident nor was he the doctor's first or even last attempt to create one eyed ghouls.
Mad Doctor: He said he gave Kaneki a kidney transplant but in reality he transplanted Rize's kakuhou into him. It seems that he is purposefully turning humans into ghouls.
Man in White: He wears a white lab coat in all his appearances since he's a doctor and has a very kindhearted face and demeanor. In contrast, many of the other characters wear dark clothes and scary masks. However, Doctor Kanou seems to be behind Kaneki's transformation and the beams falling on Rize.
Nice Job Breaking It, Hero: He saves Kaneki's life but unintentionally causes Kaneki's body to undergo a physically and mentally taxing transformation that removes any chance of continuing a normal life. As more information is learned about ghouls, the more Kaneki and the audience learn how impossible it is to do this surgery by mistake.
We Can Rule Together: He offers Kaneki a chance to become a part of his plans and seems impressed with how far Kaneki has come considering how most of the people he experimented on became nothing more than mindless monsters.
Worst Aid: Putting the organs of a victim that was pulverized by steel beams into a patient in critical condition is an extremely high risk procedure and in a normal operation would more likely kill the victim as opposed to save them. Although he already knows Rize is a ghoul and that her regenerative abilities would likely save Kaneki's life, regardless of his reckless procedures.
Kuro and Shiro
Twin sisters that, like Kaneki, became One-Eyed Ghouls. They are Dr. Kanou's bodyguards and their past may contain hints about a larger conspiracy at play.
Bodyguard Babes: They initially act as this to Madam, while at the Ghoul Restaurant. In truth, they are Dr. Kanou's bodyguards.
Combat Tentacles: Notably similar to Kaneki's kagune, which makes him suspicious.
Dark and Troubled Past: They were the children of a wealthy father, and lived happily in a mansion. One day, a Ghoul came and murdered their parents in front of them. They were taken in and trained by CCG prior to becoming Dr. Kanou's test subjects. It is suggested their parents may have been murdered as part of a larger conspiracy.
Disease Bleach: Shiro once had dark hair like her sister, prior to the surgery to make a One-Eyed Ghoul.
Single-Minded Twins: They don't show much individuality, possibly due to their unemotional nature.
Transhuman Treachery: Originally among the children raised by the CCG as future Investigators. However, they became involved with Dr. Kanou's experiments and abandoned their humanity.
What Happened to the Mouse?: Their fate remains unclear after the battle at Dr. Kanou's laboratory. The last time we saw them, Nashiro had been seriously wounded and Kurona had refused to abandon her. It isn't known whether Nashiro survived, or what happened to Kurona afterwards.
A gang of Ghouls originating from the 13th Ward, and noted for their iconic Clown-themed masks. Their members have connections to various other groups within the Ghouls world, and they have a hand in the mysterious events going on behind the scenes.
Chekhov's Gun: Mentioned throughout the series, with their members appearing among the various factions of Ghouls. They were the reason Yamori was imprisoned and interrogated for information, Nico is the one to provide Kaneki with clues about the connection between Madam A and Dr. Kanou, and Souta dropped the steel bars on Rize. Uta and Itori also played their parts in stringing Kaneki along for their own purpose.
It Amused Me: They seem to do things solely for their own amusement, declaring that life isn't worth living if it isn't entertaining.
Monster Clown: Their primary identifying trait is the use of Clown-themed masks, and they appear to be a particularly dangerous group.
Blond Guys Are Evil: Subverted. While he had light-colored hair in his youth and described himself as far more violent, he still showed glimpses of his true kindness and was the one to extend the hand of friendship to Renji. Only not so much.
Cool Mask: He's the one Ghouls go to for their masks, and he has a massive collection displayed in his studio.
Dark Is Not Evil: He has tattoos all over his body, piercings, and never bothers to hide his Game Face. Even so, he's very laid back and mild-mannered. Except that he's not nearly as kind as he seems.
Eyescream: Casually eats an eyeball in front of Kaneki.
Honey Trap: Uta used her as such when they were younger. She did not appreciate it.
I Do Not Drink Wine: Instead, she drinks blood as though it were wine. Kaneki is suitably unnerved.
Knowledge Broker: She teases Kaneki with several pieces of information, but wants him to find out about the rumored Ghoul Restaurant in exchange. Her bar seems to be an important place to trade in information, regardless of faction.
Ms. Fanservice: Beautiful and often wearing revealing clothing, in her youth she actively used her looks to her advantage.
Obfuscating Stupidity: For all her playful teasing and loud personality, she is a major broker of information for the Ghoul community. You've got to be incredibly shrewd to navigate the various factions and gangs, and owning a business as a Ghoul can be incredibly dangerous.
Pet the Dog: He attempts to talk Yamori out of killing two prisoners, and expresses sorrow over their deaths afterwards.
Screw This, I'm Outta Here!: When the raid begins on Aogiri's hideout, he abandons it without a second thought. It seems he was only hanging around because of Yamori, but once his "love nest" is ruined he loses interest.
Too Kinky to Torture: Having a hole punched in his side by Yamori seems to be flirting, with him responding that they should save the rest for home.
Transvestite: Very fond of fashion, as well as makeup. He even refers to himself as "Big Sis".
Hero-Worshipper: She appears to be a big Kaneki fangirl, coming to the 20th Ward and getting a job at Anteiku in hopes of meeting him.
The Mole: She seems to have been this, with the revelation that she's actually part of Pierrot and not just a random girl wanting to meet her hero.
Sixth Ranger: She joins the staff at Anteiku long after everyone else, and doesn't quite fit into the dynamics already established among the others.
The Ghoul Countermeasures Bureau (Commission of Counter Ghoul) is a government agency that investigates and hunts Ghouls. Their members are divided into office and research staff, and field agents known as Investigators.
Badass Normal: Investigators are ordinary humans, but take on and frequently kill dangerous Ghouls using Quinques. These specialized weapons are developed from the unique predatory organ found in Ghouls.
Cynicism Catalyst: Children orphaned in Ghoul attacks are typically placed into CCG's academy, and trained to become future Investigators. As a result, almost all Investigators have lost a loved one to Ghouls at some point in their life.
The Dreaded: The local Ghoul population gets very nervous whenever news of Investigators becoming active in their Ward, with some outright fleeing the area.
He Who Fights Monsters: Several Investigators shown have become just as brutal and merciless as the Ghouls they hunt, whether torturing their targets or being willing to disregard the safety of human civilians caught in the crossfire.
The Hunter: The Investigators are a mixture of this and Police Officers, enforcing the law by hunting Ghouls.
The Red Baron: A group-wide example. Ghouls refer to the Investigators as "Doves", in reference to the organization's seal.
Van Helsing Hate Crimes: Quite a few Investigators will show no mercy to a peaceful Ghoul, viewing them all as monsters.
A CCG rank 1 Investigator, and the secondary protagonist of the series. He was raised by a Ghoul pretending to be a Priest, and becomes curious about Kaneki after being spared by him in battle.
The Ace: He's a less extreme version than Arima or Suzuya. But he made Special class at the young age of 27. Many don't even get to that level.
An Arm and a Leg: His third fight with Kaneki ends with him losing his right arm.
Archnemesis Dad: It's....complicated to say the least. The priest that raised him is a Ghoul, currently being detained in the 23rd Ward. However, he refers to Kotaro as his "beloved son" and when CCG requires information they send him to speak to his father.
The Atoner: He sees himself as this, feeling ashamed for not being able to stop the priest that raised him from eating many of his classmates. He works for the CCG to prevent similar events from occurring.
Awesome by Analysis: While previously overshadowed by his partner, Kureo Mado, after the time skip, Amon shows off his detective skills by linking the Binge Eater case with Kaneki and suspecting that Kaneki may be involved in the ghoul world
Badass: He is noted for his exceptional strength, and is able to fight Kaneki on equal footing even as the other becomes stronger and stronger.
Badass Normal: Like all the other Doves, Amon is human but is able to hold his own against most ghouls.
Berserk Button: If any of his allies are hurt, he becomes a berserker.
Black and White Morality: He starts out this way, having believed all Ghouls to be monsters. Meeting Kaneki changes his worldview, and leads to him desperately wishing to speak to him again.
Broken Pedestal: His foster father, a Priest that turned out to be a brutal Ghoul preying on the orphans in his care. He also initially feels this way about Kaneki after he witnesses Kaneki seemingly eating Shinhara.
Rebuilt Pedestal: He regains his respect for Kaneki when Shinohara wakes up and states Kaneki only ate the Arata while restraining himself.
Conveniently an Orphan: Orphaned at a young age, which resulted in him being taken in by a Ghoul posing as a priest.
Cool Teacher: He tries to be this to Akira, to questionable effect.
Dark and Troubled Past: Raised by a Ghoul passing himself off as a Priest, using his position to eat the orphans put into his care. For some reason, Dontaro spared him out of all the children, even when he learned his foster father was a Ghoul.
Defrosting Ice King: When he first appears, he is very quiet and doesn't seem interested in socializing. But as the series continues, he opens up and is shown to be a very reasonable and nice guy.
Determinator: Amon believes in the CCG code to keep fighting even if it costs one every limb they have.
Deuteragonist: He is the focal character during chapters about the CCG.
Drop the Hammer: Uses a cylinder shaped hammer to smash his opponents. When Kaneki destroys his weapon in a fight, he upgrades to a more versatile club that can detach into blades.
Dual Wielding: He can do this with Kura, splitting it into two blades.
Took a Level in Badass: He's granted his own Arata armor, as well as a lance that allows him to face Kaneki on equal footing.
Tragic Keepsake: He has several. The cross he wears is from the church he grew up in, worn to remind him of what occurred there. Each of the Quinque he uses was passed to him after the death of the original owner.
Deceased Parents Are the Best: Played with. While alive, he seemed like a fairly vile character. However, after his death we learn that he was a devoted father to Akira and several omakes show them to be a surprisingly normal family.
Evil Genius: He is fascinated by ghouls and becomes delighted when he meets particularly unique or strong ghouls. He was steadily developing a large collection of unique Quinque from his study of Ghouls.
Face of a Thug: Played with. When he's hunting ghouls, he's exactly as much of an insane, sadistic monster as he looks, but when he's off the job, it makes his genuine kindness to his friends, family, and co-workers look a lot more sinister than it actually is.
Freudian Excuse: His cruelty towards Ghouls and obsession with making Quinques was because he was determined to gain the strength necessary to avenge his wife.
Gut Feeling: His instincts are very sharp and he can often identify a Ghoul based solely on outward appearances and vague behavior.
Hidden Depths: While he tries to eradicate ghouls with great glee, he is devoted to the cause of CCG and his co-workers, and a good husband and father to his family.
Hero Antagonist: Despite his sadistic methods, Mado is technically on the right side of the law. As a CCG Investigator, he fights and kills Ghouls for the public safety.
Walking Armory: He had MANY Quinques, because he was trying to gather the strength to kill the One-Eyed Owl.
What Measure Is a Non-Human?: He views all manner of cruelty towards Ghouls as justified, and expresses disgust over them displaying positive traits such as familial love or mercy. His views seem to be normal for most humans.
Wrong Genre Savvy: Correctly guesses that Kaneki isn't human but dismisses his hypothesis when his Rc scanner doesn't work, never stopping to think that hybrids could fool such testing equipment. Justified because hybrids were regarded as myth, since the probability of a hybrid fetus being carried to term is essentially non-existant. Also, Kaneki's case was completely unheard of, and any previous instance of a researcher bringing up this theory were quickly shot down and halted.
A strange and psychotic Investigator, partnered with Shinohara. He can be prone to acts of violence, against Ghouls and Humans alike. At the same time, he can be whimsical and almost childlike.
Abusive Parents: He was raised by a sadistic female Ghoul, and referred to her as his mother. She tortured him until he no longer responded to pain, and trained him as a Scrapper for the Ghoul Restaurant. It is implied she may have also been sexually abusing him, and she castrated him so that he would never become too masculine.
The Ace: He became an investigator simply because of his fighting skills. While others had to spends years in a academy, he's one fastest third-class investigators to be promoted besides Arima.
Ambiguous Gender: Invoked. While at the Academy, his gender was listed as "Unknown".
An Arm and a Leg: He loses his right leg to Yoshimura during the attack on Anteiku. Even so, when the Owl appears and kills Shinohara, he gets back up and keeps trying to fight.
Artificial Limbs: The Joker special portrays him as a 1st Rank Investigator, and suggests he'll get a prosthetic at some point in the future.
Character Development: His unhinged behavior lessens as the story goes on, with Shinohara helping him to develop into something closer to a normal person. In the Joker side-story, an older Suzuya is shown to be a kind partner to a younger Investigator.
Child Prodigy: There's no denying that he's an incredible fighter for someone his age and size, and he's been one since he was very young. This is because he spent his childhood as an elite Scrapper for the Ghoul Restaurant.
Combat Sadomasochist: During his battle with the twins Kuro and Shiro, he seems equally excited by hurting them as he is them hurting him.
Dark and Troubled Past: Raised by a Ghoul as a Scrapper, and regularly subjected to torture to make him Feel No Pain. She also castrated him to prevent him from becoming too masculine, hinting that she may in fact have also been sexually abusing him. After the Doves found her, he was rescued and placed into the Academy. There, he became a scapegoat to cover up the crimes of the instructor that once tortured Yamori.
Death Wail: He gives a heart breaking one when the real Owl kills Shinohara.
Determinator: Despite losing his right leg, he tried to fight Owl till he fainted.
Disproportionate Retribution: If you make him even a little angry, he's liable to do something horrible to you as revenge. Something as small as getting detained by a policeman who didn't believe his claims of being a ghoul investigator note Reasonable, given his dubious appearance and the fact he was carrying a bloodied weapon resulted in said policeman getting his eardrum sucked out and crushed for his trouble. This isn't the first nor the last time things likes this have happened.
Disproportionate Restitution: He himself never apologizes since he doesn't care at all. The apologies are made by Shinohara on the CCG's behalf, along with monetary restitution. He never faces retribution for his violent actions and behavior. Most likely, this is because his fighting abilities are too good to consider throwing him in jail.
Dude Looks Like a Lady: Everyone that met him has had trouble guessing his gender. There's a VERY good reason why. See Dark and Troubled past.
Feel No Pain: He isn't phased at despite losing his right leg.
Foil: To Yamori. Both are associated with the number 13, and both became sadistic monsters as a result of extensive abuse suffered at the hands of the opposite species.
Freudian Excuse: His unhinged behavior is almost certainly a result of the trauma he went through as a child.
Groin Attack: A truly horrifying example. He was castrated with a hammer, to prevent him from undergoing normal puberty.
I Call It Vera: Names his scythe Jason, after the Ghoul used to make it.
It's All My Fault: He blames himself for what happened to Shinohara, apologizing to his wife for his failure to protect her husband. She reassures him that it wasn't his fault.
Knife Nut: His primary weapon, an assortment of blades called "Scorpion". He was also very fond of knives during his childhood serving as an expert Scrapper in the Ghoul Restaurant.
Major Injury Underreaction: When he loses his leg, he barely reacts. He's even surprised when Shinohara begins to cry over his injury, not understanding the reason.
Pet the Dog: His relationship with his partner and parental surrogate, Shinohara, reveals that there is still a good person buried deep beneath his psychotic personality.
Psychopathic Manchild: His appearance and strange, child-like behavior are disturbing to say the least. He is noted to be deeply disturbed, prone to bouts of violence and sadism that frighten even other Investigators. Even former classmates are not given much consideration, and he seems to genuinely enjoy the suffering of others when fighting. At the same time, he seems to have little comprehension of social norms or empathy — he doesn't understand the grief of others when a classmate dies, but likewise is unable to understand Shinohara's concern for his well being. He is even suspected of torturing animals during his time at the Academy. In truth, he was innocent of those crimes and his behavior is because of the horrific abuse he suffered as a child. Under Shinohara's care, he begins to stabilize and is genuinely horrified when his partner is killed in action.
Raised as the Opposite Gender: A truly chilling example, as it turns out. The Ghoul that raised him castrated him because she liked to dress him up as a girl and never wanted him to look like a man.
Raised by Orcs: He was raised by a female Ghoul, and still thinks fondly of her as his "Mama" even years later. It is the cause of all his disturbing tendencies.
The Scapegoat: He never really tortured animals at the Academy. Instead, the staff decided to blame him for the actions of an instructor to avoid the potential scandal.
Sinister Scythe: His anti-ghoul weapon, which he promptly names after the Ghoul it was made from.
There Is No Kill Like Overkill: He's prone to doing this to Ghouls, as illustrated during the raid on Aogiri's hideout. More than one than one Ghoul is subjected to being stabbed again and again and again, while he tells them to "hang on" and is disappointed when they die too soon.
Took a Level in Kindness: Thanks to Shinoara's influence, he has slowly begun to become a more stable individual. In stark contrast to his early behavior, when he meets Mrs. Shinohara, he expresses sympathy and remorse over his partner's fate.
Too Kinky to Torture: A horrifying version of the trope. His "Mama" trained him to Feel No Pain by doing things like suspending him with fishhooks through the skin on his back and arms. As such, he no longer responds to pain like a normal person.
Voiced by: Yutaka Nakano
A former academy instructor for the CCG and a special investigator. He is currently investigating the binge eater.
A Father to His Men: He is a kind and caring superior, playfully teasing Amon and later takes Suzuya under his wing as both a partner and a father figure.
An Arm and a Leg: The One-Eyed Owl slices off his leg, then slices it into neat little pieces in order to eat it. It mocks him, stating that now he "matches" the similarly-wounded Suzuya.
Badass Normal: Much like other members of the CCG. He's a special investigator, meaning he's a top-class combat specialist.
Empowered Badass Normal: His Arata quinque grants him the speed and strength of a Ghoul, but it also begins to devour him in the process.
Big Brother Mentor: He acts as this to his partners, offering them advice or doing his best to reign in their worst behaviors.
Boring, but Practical: He's called this compared to Arima and Mado. While he isn't flashy and hasn't completely mastered his Quinque, he never the less gets results.
By-the-Book Cop: He dislikes when people get out of hand, and attempts to prevent Ghouls from suffering unnecessarily cruel deaths.
Cruel and Unusual Death: The real One-Eyed Owl slices off his leg, and eats it before finishing him off with a stab to the chest.
Not Quite Dead: Twice he's seemingly been killed in action, only to turn out to have barely survived. The second time leaves him on life support, with no chance of recovery.
Dangerous Forbidden Technique: Activating his Arata quinque gives him strength and speed of a ghoul, but in exchange the armor slowly attempts to consume him.
The Dreaded: He has earned a reputation among the Ghouls, and is feared by them as a result.
Cry Cute: Twice, she's broken down in tears and shown a more gentle side. The first time, while drunk and thinking about her father. The second, when she admits her feelings towards Amon.
Daddy's Girl: She loves her father very much, as he raised her on his own after the death of her mother.
Death Glare: She's pretty good at giving them. It was played for laughs when she gave one to Amon when she found him collapsed in her hallway drenched in sweat.
The Faceless: She has a small cameo in the anime, visiting her father's grave. Her face is partially hidden in this scene.
Foil: To Touka. They are both women who are lonely due to their families but mask it with cold indifference. They both deeply respect their fathers and look very similar to their mothers. They both inherited their fathers' defining trait. Akira, her father's intuition. Touka, her father's love for humanity. As well as having ship tease with the leads of their stories Amon and Kaneki respectively. To make the comparison even more apt, Touka's father Arata was killed by Akira's father Mado. And Mado was killed by Touka.
Ice Queen: Acts rather coldly to her partner and coworkers, though this may simply because she is still coping with her father's recent death.
Defrosting Ice Queen: Based on Takizama's memories, she never talked to anyone in the academy. The fact she's talking that with Amon is pretty shocking.
Badass: THE ultimate badass of the CCG, if not the entire series. He is a legendary Investigator, noted to have ended the killing spree of the One-Eyed Owl by dealing a supposedly-fatal blow to the most dangerous Ghoul ever encountered, and survived to tell about it. He has earned his title as "Shinigami" for effortlessly slaughtering Ghouls, and he manages to effortlessly deal Kaneki in his half-Kakuja state a devastating blow.
Invincible Hero/Invincible Villain: Depending on which side the story has the audience rooting for at the time. Kaneki and the One-Eyed Owl, two of the strongest Ghouls in the setting, cannot even touch him.
Mystical White Hair: His unusual hair color seems to hint at his nigh-superhuman abilities, and frightening reputation. It was originally black, but like Kaneki he went through something that turned it white.

The Ace: Dealt a fatal wound to the One-Eyed Owl, and established himself as one of CCG's strongest Investigators.
A Special Class Investigator, and commander of the 11th Ward Special Countermeasures Unit organized to combat Aogiri Tree. He is highly experienced, but also has an abrasive personality.
Badass: If his high rank weren't evidence enough, he proves himself when he finds his men pinned down by gunfire from Ghoul snipers. He berates them, but then grabs the nearest gun and takes out several snipers in a row like it was nothing.
Badass Biker: He likes to think he's this, but instead his motorcycle keeps getting stolen by the real deal.
Boom, Headshot: Delivers several in a row to Aogiri's snipers, establishing he's more than a big mouth.
Jerkass: He's prone to running his mouth, saying unflattering things about Mado after his death or teasing Suzuya about his youthful, androgynous appearance.
Running Gag: Suzuya stealing and promptly wrecking his motorcycle while doing something heroic and awesome.
Tempting Fate: He gets in Suzuya's face and mocks him, but is saved by Shinohara's intervention. The last person to annoy Suzuya got his ear drum sucked out and crushed for his efforts.
We Have Reserves: Averted when Shinohara's team face off against the One-Eyed King. He tells Shinohara to have all troops who can't hold their own against the creature back down lest they needlessly die.
A Rank 2 Investigator, assigned to investigator the Gourmet Ghoul. He deeply admires both Amon and Arima, and harbors something of an inferiority complex.
Adorkable: He's very young and somewhat awkward, as well as prone to fanboying over his more exceptional peers.
Always Someone Better: He frequently feels that he is always second-best to more exceptional individuals.
An Arm and a Leg: Noro bites his arm clean off, and takes part of his torso with it.
Cowardly Lion: Though weeping with fear, he refuses to abandon a wounded-Amon and faces down Tatara, who had just finished slaughtering his squad.
In Vino Veritas: When he gets rip-roaring drunk, he ends up screaming challenges to Akira and answers his phone by calling the person (his partner) names.
Kill the Cutie: He's reported among the dead at the conclusion of the attack on Anteiku, having been killed while trying to protect a wounded Amon from Aogiri.
The Knights Who Say Squee: He's one of the top graduates of the Academy, but absolutely worships truly skilled individuals like Amon and Arima. He even goes on about the clippings he keeps of Arima's cases.
Momma's Boy: He spends his day off with his mother, getting fussed at about not having a girlfriend and generally fussed over by her.
Unknown Rival: Downplayed. He maintains a certain level of jealousy towards Akira, the top of their class. But his sense of rivalry doesn't really come out until both end up roaring drunk, at which point he declares it a serious battle.
He is Kaneki's best friend. Although he comes off as a goof ball, he is incredibly perceptive and intelligent when he wants to be, so much so that some ghouls see him as a threat since he could expose them.
Amateur Sleuth: He admits that he enjoyed bugging and tailing anyone he thought was suspicious, in the hopes of solving crimes. When he tails Yamori and discovers the existence of Aogiri, he leaks it anonymously to CCG. Later, he officially joins them as an Intern and gets promoted to an assistant in the Investigation department due to his great intuition. He even figured out Kaneki was a ghoul.
Hyper Awareness: Although he can act quite silly and carefree, he is incredibly perceptive. He immediately dislikes Nishio, although he doesn't act like it, because he can sense there is something off about the other. While having a conversation with Kaneki about Hinami's case, he is able to piece together what's really going on based on a few details. He also figures out what's up with Kaneki without the other telling him and even gets promoted from intern to assistant at the CCG headquarters due to his skills.
Locked Out of the Loop: Touka says that she will kill him if he finds out since humans discovering a ghoul's secret tends to end very badly. Kaneki also worries that Hide will stop being his friend if he finds out that he's a ghoul. However, Hide seems to be piecing some things together on his own and knows there's something up with Kankei starting around Hinami's character arc. He also later starts working with the CCG and later meets with Kaneki again in chapter 136 and by then he's already figured out that Kaneki is a ghoul.
Muggle Best Friend: After realizing how perceptive Hide can be, Kaneki gets worried that he'll figure out the truth and that their friendship will end. Toka has also threatened to kill him if he were to discover the truth. He figures it out anyway but doesn't betray Kaneki.
Nice Guy: Very. He incredibly cheerful and upbeat. Kaneki stated if it wasn't for Hide, he doesn't know what would have happen to him. He even happily accepts Kaneki despite knowing he's now a ghoul
Only Friend: Hide doesn't have much competition in the status of best friend as Kaneki's tragic childhood and dysfunctional family have turned him into an introvert with little other venues of emotional support. He also doesn't abandon Kaneki despite the other having turned into a ghoul.
Out of Focus: Kaneki's relationship with Hide was one of the most important things in the beginning of the manga. However, as Kaneki became more involved in the ghoul world, interactions between the two became more scarce and we didn't see Hide for many, many chapters. He comes back as a member of the CCG later and even helps out Kaneki, fully aware that the other is a ghoul.
What Happened to the Mouse?: He is officially Missing in Action after the battle in the 20th Ward. He was last seen comforting a wounded and hallucinating Kaneki, leaving the possibility that his best friend ate him.
A famous author, noted to have published her first work as a teenager. She is Kaneki's favorite writer, and has several fans among the Ghouls in the story. In person, she is easy-going and somewhat quirky, but far more insightful than it would seem. For more information, see The Reveal.
Chekhov's Gunman: She's the author of Kaneki, Rize, Tsukiyama, and Hinami's favorite books. As a result, she's been discussed repeatedly throughout the story and begins playing a role in the plot once she finally appears in person. Turns out, she's actually not only Eto of Aogiri Tree, but the infamous One-Eyed Owl.
Cloud Cuckoolander: She comes across as very quirky and strange, cheerfully ignoring the rules of her own autograph sessions.
Cool Big Sis: She takes an immediate liking to Hinami, and offers her advice.
Government Conspiracy: She seems to believe there is one, offering Amon hints that CCG may have a hand in the creation of Ghoul Hybrids like Kaneki.
Mystery Writer Detective: At least in that she managed to dig up some interesting information, offering it to Amon while interviewing him for her new book.
Parental Abandonment: Like most of the cast, she lost her parents early on. Or rather, her father was forced to abandon her in the 24th Ward to protect her from the organization known as "V".
Pen Name: Sen Takatsuki isn't her real name, but rather the one she uses for her writing.
The Reveal: She's the Half-Human Hybrid child of Yoshimura, the One-Eyed Owl. Not only that, but she is also the Aogiri Tree executive, Eto.
Foreshadowing: Multiple pieces easily missed the first time. Yoshimura states he has "no son", because of course he has a daughter. As Takatsuki, she shows an unusual insight into the events going on behind the scenes and interest in the RC sensors at CCG headquarters. She also expresses interest in writing a book about a Ghoul after talking to Kaneki, because of course she already knows all about him.
The Storyteller: Her novel, The Black Goat's Egg, seems to be a reflection of Kaneki's unfortunate circumstances. After meeting him, she becomes interested in writing a story about a Ghoul.
Teen Genius: She published her first book as a teenager, and it went on to be a best-seller. She's published 8 works total, and she's only 24.
Unkempt Beauty: Though we've never seen her anything but disheveled, Kaneki states that she's admired by fans for her great beauty.
Innocently Insensitive: Since she doesn't know that Touka is a ghoul, she doesn't realize how much troubles she gives Touka by bringing her normal food. Touka has to force herself to digest her food to not hurt Yoriko's feelings.
Muggle Best Friend: She is unaware that Touka is a ghoul and seems to be an average high school girl.
