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 main character of Tokyo Ghoul: JACK, a story based on his youth.

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 with unusual long white colored hair (similar to Ken Kaneki whose hair also turned white). Always seen wearing glasses, his face always keeps an apathetic expression, rarely showing any emotion if not at all. Arima is a well dressed individual who is always seen wearing, 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, and always carried on his back, a 'guitar case,' which most people perceived it to be. 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 0.1. (Not specified in the chapter). As a teenager, Arima exerted the same personality, and also noted his main hobby to be ghoul extermination.

Arima is not beyond complimenting his ghoul opponents as he did so when Kaneki broke 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 and makes mention 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 Arimanotice a scratch on his right check that is bleeding. Later on, he is seen confronting the One-Eyed Owl.

Post-20th Ward One-Eyed Owl Battle
Alongside Yoshitoki, they appear in front of Director Tsuneyoshi 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 responds by saying he will take care of it and in the panel next to his is a black suitcase, contrary to all the grey/silver suitcases most CCG investigators carry their quinque in.

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. He was able to put Ken Kaneki in a state of dismay from his presence alone. He has also shown to have incredible speed and reflexes as he quickly reacted towards Kaneki's advances. It had been stated by Kaneki that he was undefeated.

In the past, he dealt with a young Renji Yomo without difficulty. He is the only combatant that has defeated the One-Eyed Owl(though it was Yoshimura and not the real one) without suffering any injuries.

Quinque

 * 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.
