Kishou Arima

Kishou Arima (有馬 貴将, Arima Kishō) is a famed Special Class Ghoul Investigator known as the CCG's Reaper (CCGの死神, CCG no Shinigami). He is undefeated as a Ghoul Investigator and at some point was formerly partnered with Take Hirako. He is the protagonist of the spin-off Tokyo Ghoul: Jack, alongside Taishi Fura.

His investigative skills and prowess in combat has led many investigators, such as Koutarou Amon, to admire him.

Appearance
Arima is a fairly tall man that has unusually long pink colored hair. He is always seen wearing his glasses, with his face kept in an apathetic expression, rarely showing any emotion if not at all. Arima is also a well dressed individual who wears, like all ghoul investigators, a suit and tie, and, when on duty, a white overcoat.

During his youth at Seishin Senior Highschool, he was mostly seen dressed in his standard school uniform. He also always carried on his back what was perceived to be a 'guitar case.' However this was only a concealment for his blade quinque, Yukimura which he used to fight ghouls. He also had dark blue hair.

Personality
Arima has a very calm personality, remaining unperturbed and composed even when surrounded by twenty-five ghouls. He is also an overly strict mentor, as seen when he reprimands Hirako for being off on his attack by 0.01 seconds. As a teenager, Arima exerted the same personality, and also noted his main hobby to be ghoul extermination. He has a very cold and calculating approach to exterminating ghouls as shown when he was about to finish off Renji and Yoshimura appeared suddenly, instead of panicking or attacking he merely greeted the ghoul.

Arima was shown to respect the dead as he reprimanded Itsuki Marude when he talked ill about Mado after his death.

He has indicated that despite his stoic personality, he is capable of forming friendships, as he borrowed Haise Sasaki's book, and Akira Mado described his feelings towards Sasaki as "parental love". Arima is also not beyond complimenting his ghoul opponents as he did so when Kaneki damaged his quinque, Ixa.

Past
Arima was hailed as a genius within the CCG, stemming from his affiliation with the organization since his teens. He was personally selected by CCG's chairman Tsuneyoshi Washuu to be promoted to a 3rd class investigator. Due to his outstanding talent, he was promoted to 2nd class investigator in less than a year. During the One-Eyed Owl's third attack in the 2nd ward, he gathered all the Special Class Investigator quinques and worked his way up to the One-Eyed Owl. He was the one who dealt fatal damage to the One-Eyed Owl resulting in a CCG victory.

Doves' Emergence
After Itsuki Marude had expressed his aversion to Kureo Mado's work ethic and fixation on Quinques at Mado's funeral service, Arima reprimanded him.

Anteiku Raid
After being given the missions to ambush any fleeing ghouls and neutralize the One-Eyed Owl, Arima was stationed within the underground route V14 where he had slaughtered a vast amount of ghouls by himself. Upon having his gaze fall on Ken Kaneki he quickly approached him with the intention of completing his mission and, without giving off any sudden warning, dealt an attack towards him. Arima had quickly lunged his quinque IXA through the back of Kaneki's skull, piercing his brain and ultimately coming out stabbing his left eye. He then began to easily dodge Kaneki's rapid Kagune strikes without showing much effort before witnessing his sudden emotional outburst. He quickly makes note of who Kaneki is, then mentions that it was raining outside which he knew from the sound of water pouring in, also stating that his sense of time gets dulled when he is underground. Arima quickly brings out his other quinque Narukami and activates it, stating the objective of his mission before releasing dangerous bolts of electricity. After having Kaneki dodge this he commanded his quinque to go into remote activation and kept going as like his previous attack. He easily blocked a strike from Kaneki's Kagune using Ixa's defensive barrier but was surprised as it been broken and then complimented him for his attempt. Arima then went on to pierce Kaneki through his body with Ixa which raised him from the ground before dropping him in front of the man. After stating how he hadn't expected Kaneki to damage his quinque, he stabs Ixa through his head before mentioning he needed a new quinque. After that Arima noticed a scratch on his right check that is bleeding. Later on, he is seen confronting the One-Eyed Owl and he managed to injure her, but she escaped.

Post-20th Ward One-Eyed Owl Battle
Alongside Yoshitoki Washuu, he appears in front of Chairman Tsuneyoshi Washuu discussing the results from the operation in the 20th ward. The director is seen holding a piece of paper with Kaneki's profile crossed out and marked as 'Erased'. He speaks to Arima informing him the 'ownership rights' are his and asks him what he will do about the name. Arima replies that he will entrust it to him  and next to him is a black suitcase, contrary to all the grey/silver suitcases most CCG investigators carry their quinque in.

Timeskip
Some time after the Anteiku Raid, Arima along with Akira Mado are in charge of supervising Haise Sasaki and his Quinx members.

Power and Abilities
Renowned as one of the most famous and admired investigators in the entire CCG, Arima possesses unimaginable fighting capabilities, being able to bring out the full potential of his quinques. In the past, he dealt with a young Renji Yomo and Yakumo Oomori without difficulty. He is also able to put Ken Kaneki, an SS-rating ghoul, in a state of dismay from his mere presence. Despite being a human, he has shown to have monstrous speed and reflexes and it had been stated by Kaneki that he was undefeated. He is the first combatant to defeat the Fake One-Eyed Owl and the only one to have overwhelmed the Real One-Eyed Owl.

Quinque

 * Yukimura 1/3: A koukaku type quinque that takes the form of a sword consisting of a long, thin blade without a hilt. This quinque was used during Arima's early days as an investigator.


 * IXA: A koukaku type quinque that takes the form of a lance attached to a gun-sword handle with a spiked pommel. The quinque is capable of forming into a shield that is capable of blocking potent attacks coming towards Arima, such as Yomo's kagune.


 * Narukami: A ukaku type quinque that takes the form of 4 satellite panels attached to a rapier handle. The quinque can shoot bolts of lightning that can home towards a target of Arima's choosing. It also has the ability to combine the panels into a single rapier blade, that's able to cut the One-Eyed Owl's arm..
