Koutarou Amon

Koutarou Amon (亜門 鋼太朗, Amon Kōtarō) is a First-Class Ghoul Investigator.

He was Kureo Mado's last partner. His last partner was Akira Mado, prior to being declared dead.

Due to a personal experience as an orphan during his childhood, Amon has come to the conclusion that this world is wrong, so he has made it his task to change the world. Because he thinks it's the ghouls that are twisting the world, he views the eradication of all ghouls as a way to mend this world. After being spared by Ken Kaneki, Amon has started to question the righteousness of his crusade.

He has a certain interest in the two ghouls Rabbit and Eyepatch.

At the end of the Owl Suppression Operation, he faced Tatara together with Seidou Takizawa. He was subsequently reported dead by the CCG, although the manga hinted that he was one of the many investigators whose bodies went missing undefined. His true fate or whereabouts are unknown.

Appearance
Amon is a tall, young man with black hair and teal eyes. Due to his constant, vigorous training, he has an extremely athletic and muscular build.

Like most ghoul investigators, Amon usually wears a black suit with tie. If he leaves for an investigaton, he additionally wears a white overcoat on top of his suit. He also wears a necklace with a cross.

Personality
At heart, Amon is a likeable, sympathetic young man with a great sense of justice and dedicated to his cause. It appears that his hatred for ghouls came when his foster father, Donato Porpora, was exposed of his crimes. This incident led Amon to believe that ghouls made the world wrong and that hunting ghouls would be the first and only step towards making it right.

He feels responsible for the death of his partner, Kureo Mado.

After his fight with Kaneki, he has shown interest and curiosity by wanting to understand him, however their future encounters ended up with both of them fighting one another.

Past
Koutarou Amon was orphaned at some point very early in his life, through unknown cause. He was taken to a Catholic orphanage and cared for by the Priest Donato Porpora, living a peaceful and happy life there. However, one night he stumbled in on his foster father butchering a child that had supposedly been adopted and learned he was being raised by a Ghoul. The orphanage was merely a front, allowing the seemingly-kind Priest to feast on child victims without raising suspicion. Even though his secret was revealed, Donato allowed Amon to live -- an event that shaped the course of his life.

The infamous "Priest" was eventually captured by CCG, while Amon would be raised in one of their Junior Academies. He later entered the Ghoul Investigator Training Academy and graduated at the top of his class, becoming the partner of senior Investigator Kureo Mado. Amon was initially uncertain of his unusual partner, and disagreed with his reliance on intuition during investigations. His first investigation involved the serial-predator "Applehead", a dangerous Ghoul responsible for many deaths. Mado's prime suspect was Kie Muramatsu, an elderly woman -- Amon's reluctance to suspect the woman nearly allowed her to kill him. However, Mado arrived in time to save his life and taught him to trust his partner's keen instincts.

Doves' Emergence
After they had killed Asaki Fueguchi, Amon and Mado came to the 20th ward in pursuit of Ryouko Fueguchi and her daughter Hinami Fueguchi. By desecrating a grave that Ryouko Fueguchi had visited, he was able to turn up evidence that the grave most likely belonged to Hinami Fueguchi's father.undefined That served as proof that Ryouko Fueguchi was connected to this ghoul, so they confronted her together with investigators of the 20th ward branch office.undefined After Ryouko Fueguchi had attacked the investigators to give her daughter the opportunity to flee, Mado and Amon defeated her and finally, Mado killed her.undefined

After he and 20th ward's investigators Ippei Kusaba and Yasunori Nakajima had gone for dinner, they they were attacked by Rabbit. Kusaba was killed and Amon was losing because he didn't have his quinque with him. He and Nakajima were saved by Kureo Mado.undefined

On the basis of false information spread by Touka Kirishima,undefined Amon and Mado investigated Kasahara river, but were unable to find a hint about the Daughter Ghoul. Amon proposed to leave, but Mado wanted to stay and told Amon he should leave ahead.undefined When Mado called him as Mado attacked Touka and Hinami, Amon hurried to his partner's side, but was stopped by Kaneki.undefined In the fight between Amon and Kaneki, Amon lost with his quinque being destroyed, but he was spared by Kaneki.undefined Afterwards, Amon hurried again to Mado's location, but Mado was dead when he arrived.undefined

Aogiri Arc
Because he felt guilty for Mado's death, Amon became obsessed with his job. He considered the two fake students that provided the fake information to be the key.undefined

To his surprise, headquarters deployed Yukinori Shinohara, Kousuke Houji, Seidou Takizawa and Juuzou Suzuya to the 20th ward, the special investigators being major figures in CCG. This was a measure to deal with the dangerous stand-alone ghouls in the 20th ward. Additionally, CCG's 11th ward branch had become powerless, so the deployment was also meant to prevent the destruction of CCG's 20th ward branch. Otherwise, a pincer attack on the wards between the 11th ward and the 20th ward could not be avoided.undefined The commander of the 11th Ward Special Countermeasures Unit orders that Amon, Shinohara and Suzuya shall participate in the unit.undefined Because Doujima 1/2 was destroyed, Amon needed a replacement. Shinohara proposed that he could choose one of Mado's quinques, as Mado had written in his will.undefined

During the 11th Ward Battle, Amon used his new Quinque Kura to fight two of Aogiri's Executives, the Bin Brothers. Recalling Mado's advice about using any means necessary to win, he was able to kill the S-rated Ghouls and help secure a victory. As the battle came to a close, he noticed Kaneki from a distance but was unable to catch up with him. He was left haunted by his wish to speak to the unusual Ghoul and learn more about him.

Raid of Kanou's Lab
In the six months following the battle in the 11th Ward, Amon was promoted to First Class. With his promotion to a Senior Investigator, he was assigned a new partner -- Akira Mado, the daughter of his previous partner. The two first met as he gave a report at Mado's grave, and Amon quickly found himself struggling to deal with her. Akira made things difficult for him, arguing small details and refusing offers to spend time together away from the office.

During the raid on the Ghoul Restaurant, the team discovered dozens of corpses and evidence that another Ghoul had carried out the slaughter. Based on the evidence of an Rinkaku capable of shattering a Quinque, he theorized that the Eyepatch Ghoul was responsible for the massacre of the members.

In order to gain more information about Aogiri, Marude sent him to interrogate Donato Porpora about the attack on the Ghoul Detention Center. Instead, his foster father teased him about his new partner and asked questions about his personal life. Unable to get any further and angry over his past, Amon prepared to leave emptyhanded. However, Donato cryptically advised him to seek "Alice" instead of the "Rabbit", referencing the story "Alice in Wonderland".

Though puzzled by these words, Amon continued his investigations of Rabbit with the assistance of an assistant, Hideyoshi Nagachika. His investigations eventually led him to discover something special involving Akihiro Kanou, and led a team of Investigators to check out his mansion. There, the group discovered an underground facility. Amon, Akira, and two other Investigators fought against the combined forces of Shuu Tsukiyama and Naki. After a fierce battle that left Naki and Akira both wounded, the Investigators were able to drive the Ghouls off. Receiving word of Shinohara needing help, he arrived to discover an out-of-control incompletely Kakuja seemingly eating the veteran Investigator. Amon recognized the Ghoul as "Eyepatch" and flew into a rage, battling him while demanding to know about their previous encounter. He was assisted by Juuzou, but hesitated and allowed Kaneki to escape after seeing him weep in pain. Afterwards, he berated Juuzou for abandoning his partner.

Afterwards, Amon found himself haunted by the sight of Kurona and Nashiro Yasuhisa as One-Eyed Ghouls.

After a busy day at the office, Amon joined Seidou and Akira for dinner and drinks. Both ended up drunk, and Amon was unable to stop their argument until Seidou was forced to return to the office. Alone with Akira, their discussion turned to the death of her father and the bitter feelings both felt over it. Akira confessed to her feelings of resentment towards him, and her guilt over holding her father back. He agreed with her, blaming himself for his failure and swearing to protect her. When she passed out drunk, he took her home and watched over her as she broke down in tears. His conflicted feelings resulted in him going out onto the balcony to do pushups, berating himself for his failures as a partner. In the morning, Akira found him still outside and cooked him breakfast as thanks for his help.

On the eve of the Owl Suppression Operation, he visited the graveyard to see Harima and Mado. While there, he encountered Akira and they spoke at length about the people they had lost. Akira attempted to kiss him, but was rejected and stormed away.

Anteiku Raid Arc
During the operation, Amon is assigned to the 4th Squad as Squad Leader. His orders take him to the outskirts of the operation zone, helping to prevent entry or escape of any Ghouls. Along with his squad, he faces down members of En and prevents them from escaping the 20th Ward. Eventually, he comes face to face with Kaneki as he attempts to break through the blockade. Amon is surprised that once again, the two have crossed paths during a major event. He wonders whether this means that the Ghoul is his reaper, and refuses to allow him through. Under the guise of a challenge, Amon gives his long-time rival his name and wishes for him to survive the battle so that they can finally talk. Though he recognizes Kaneki's intention to break his Quinque as in their previous battle, he's unable to prevent it and goes down.

Just then, Doctor Chigyou arrives with the rebuilt Doujima and an Arata armor, throwing both cases to him. Amon dons the completed armor and wields his new Quinque, quickly knocking Kaneki unconscious with a single blow. Losing control over his Kakuja, Kaneki continues to attack Amon and their battle soon leads them away from Squad 4. Eventually, their battle ends when both critically wound each other -- leaving Amon without his arm, and Kaneki with an enormous hole in his side. As he collapses, Amon is shocked to find his thoughts wander to his foster father, filling him with conflicting emotions.

Prompted by Akira's feeling that something was wrong, Seidou Takizawa locates a wounded Amon in a side street. As Amon regains consciousness, the pair are located and joined by the squad commanded by Mutsumi Chino. They prepare to radio for medical assistance, but are ambushed by Tatara and several members of Aogiri. The supporting squad is quickly wiped out, leaving Amon and Takizawa alone against the Ghouls. Amon orders his friend to retreat, preparing to fight alone in spite of his injuries but Takizawa refuses and opens fire. Tatara quickly dispatches him, horrifying and enraging Amon -- with a scream, he charges Tatara who responds with amusement.

He is officially listed as killed in action by the CCG. It is currently unknown if he is among the missing dead investigators.

Donato Porpora
Donato was his ghoul foster parent and they lived together in a Catholic orphanage. But one day, Amon discovered that Donato had been slaughtering the children in the orphanage daily, which made Amon grow a sense of hatred toward him. Since then he has cut his ties with him, and refuses to recognize him as his foster family. When defeated by Kaneki, Amon is frustrated over how he remembers Donato as his father, thinking why it was him even in a moment like that.

Kureo Mado
Mado was Amon's first partner and a mentor in Amon's eyes. He respected him greatly and learned a lot from him. When Mado was killed, he underwent a phase of great sorrow and promised to catch Rabbit, the ghoul who killed him. Amon still feels responsible for arriving too late to save his mentor, as he reveals to Akira when she is drunk.

Akira Mado
Amon's second partner/first subordinate. They met for the first time in the cemetery where both had gone to pay their respect to Kureo's grave. At first, their relationship was strained because Akira held Amon responsible for her father's death. After a several ghoul incidents, and a time wherein Akira had gotten drunk, their bond grew closer and they started to work well together. Before the battle against Anteiku, Amon offered her a cat strap because it reminded him of her cat, and they went together to see Kureo's grave one more time, Amon asking her not to be rash in the future battle against Anteiku. Akira may have romantic feelings toward Amon as she tried to kiss him once, which he stopped. It is then showed that the two are in completely different teams during the battle against Anteiku. She ends up confessing later in the manga that she does in fact have feelings for him and her old school rival.

Yukinori Shinohara
Shinohara was Amon's teacher in the CCG academy, and Amon respects him a great deal. Just like Mado, Shinohara is like a mentor for him, and when Ken Kaneki hurt him in Kanou's laboratory, Amon became enraged and immediately went to fight Ken.

Juuzou Suzuya
Amon considered Suzuya to be quite weird and was angered by his carefree attitude and how he was uncaring of Shinohara's injuries, but later started to get along, though Amon said that he still doesn't understand the way Suzuya sees the world.

Seidou Takizawa
Takizawa and Amon are on great terms, Takizawa admiring Amon a lot. However, since Seidou's not getting along that well with Juuzou or Akira, Amon often has to play the conciliator. Amon respects him as a true comrade and flew into a distraught rage when Takizawa was seriously injured by Tatara and Noro.

Ken Kaneki
At first Amon thought Kaneki was just a regular ghoul. However after being spared by Kaneki after their first confrontation and seeing him crying while begging him not make him a murderer, Amon begins to gain interest in Kaneki as to why he was spared and what his motivations are. Once Amon concluded that Kaneki and Rabbit were the key to solving Mado's death, he began pursuing Kaneki in search of answers. Amon was responsible for stopping Kaneki's rampage when he was raiding Kanou's Lab. Kaneki is the only ghoul that Amon does not seem to have any real hatred or scorn for, although he has a lot of questions that he wanted to ask him. After fighting Kaneki during the Anteiku Raid, Amon lost his arm. Even after being severely wounded by Kaneki's kakuja, Amon persists to stay alive in order to prevent Kaneki from becoming a murderer.

Touko Harima
Amon's old friend, his first Quinque (Doujima 1/2) is a memento left by Harima. He still remembers her fondly.

Kishou Arima
As Arima is the strongest Investigator, Amon has respect and admiration for him.

Power and Abilities
Because Amon is extremely athletic, he is able to fend off ghouls to some extent even if he doesn't use his quinque, and may be able to deal with weak ghouls without using the quinque at all. As a dedicated, disciplined ghoul slayer, he always trains extensively in weight lifting to match against ghouls who are naturally stronger than average humans. This strength allows him to wield heavy Koukaku quinque.
 * Doujima 1/2 (ドウジマ1/2, Dōjima 1/2) A koukaku quinque which takes the form of a club. It's a simple quinque that is used to swing heavy blows that are tough to block. This quinque is a memento of Harima. During the climax of their fight, Kaneki Ken was able to cut the quinque, making it unusable. Before the battle against Anteiku though, Akira Mado comes up with a solution to repair it. Amon was given the repaired Doujima after Kura was destroyed by Kaneki. The repaired Doujima 1/2 takes the form of a lance like spear. The quinque was repaired by using the Bin Brother's kagune. For additional offensive power, the brothers kagune can be projected from the spearhead, spiraling around it in a drill-like manner. Using this ability, Amon was able to severely injure Kaneki to the point he couldn't regenerate.
 * Kura (クラ) The koukaku quinque Amon wields during CCG's 11th Ward Battle. It is a quarterstaff with a large blade at its end that can take down multiple ghouls in a single swing. The blade can be separated into dual falchion blades to lure opponents off guard and have a quicker weapon at hand. While the swords are a bit heavy for single hand use, Amon can also throw and retract them for longer reach. Currently, Amon is using this quinque because its weight is similar to Doujima 1/2's. Mado bestowed the quinque on him in his will. It was destroyed by Kaneki during Amon's fight.
 * Arata proto • II: A koukaku quinque that is an upgrade to its predecessor Arata Proto. This quinque takes the form of a suit of armor that wraps Amon's body in a spiral-like fashion. Additionally, Arata Proto II creates a mask that takes the shape of a bird with two small curved markings stacked above two larger markings. Like it's predecessor, Arata Proto II augments Amon's strength, speed and durability to the point of being able to fight toe to toe with Kaneki, a SS ranked ghoul for a period of time. However using the quinque bears a heavy burden on the body which could be mitigated due to Amon's high physical abilities. The quinque was destroyed by Ken Kaneki in his kakuja form.
 * Unnamed Quinque: A quinque of unknown type that Amon used during his early days as an investigator. It took the form of a spear with a harpoon-like head. It's capabilities remain unknown as Amon was disarmed by Kie Muramatsu before he could use it.

Trivia

 * Amon likes to train and investigate.
 * Amon likes to eat sweets like donuts, but dislikes spicy food.
 * Amon is actually the name of an Egyptian god meaning "god of all gods".
 * During his second fight with Ken, Amon used Arata Proto II as well. In the 11th episode of Tokyo Ghoul Root A, Amon just fought with his Doujima. Also in the manga, Amon first used Kura to fight Ken, and then uses Doujima after Kura was destroyed by Ken. But in the anime, Amon started fighting Ken by using Doujima from the start. In the manga, Amon was defeated by Ken when he was forced to use his Kakuja form. In the anime, Ken defeated Amon without using his kakuja form.
 * During the end of the auction raid, some CCG investigators noted Kuroiwa Takeomi being the first to defeat a ghoul bare-handedly since Amon Koutarou.
