"These ghoul bastards are putting us through the paces. For the sake of peace they must die."
Kaiko is a mysterious ghoul that overshadows his eyes with a black top hat and unique dark lips. He wears a formal suit underneath a black duster coat and conceals his hands with dark gloves.
Not much is known about Kaiko except that he is loyal to the organization V, and is targeting Eto and Aogiri Tree due to disrupting the stability of ghouls and humans. Kaiko believes in poise and decorum as he berates Furuta for his improper speech while deferring to Arima's verbal report.
Not much is known about Kaiko's past other than he used to know Yoshimura before he left their organization.
Owl Suppression Operation Edit
He appeared to Yoshimura and offered him one last chance to rejoin them by giving up Eto to them and swearing loyalty to V. After his offer was refused he told Yoshimura that he should go and die, and that there's nowhere for Yoshimura to run, because he's inside a cage.
Post-Rose Extermination Edit
Arima and Furuta reported in to Kaiko at one of V's establishments about Eto and the likelihood of her being the "King". He ordered Arima to deal with something associated with Rize and Furuta to continue shadowing Kaneki.
Third Cochlea Raid Edit
Clown Siege Edit
Kaiko was present among the group of V members heading for the laboratory. Afterwards, he reappeared in the battleground, witnessing Matsuri Washuu killing V, CCG, and Clowns members. Kaiko stated that the Washuu bloodline was a thorn in V's side before brutally killing him by cutting him into ribbons.
Yoshimura and Kaiko used to be part of the ghoul organization V. Years after Yoshimura left the organization and before the CCG attack on Anteiku, Kaiko appeared to Yoshimura and due to being old acquaintances, he offered to help him in return for swearing loyalty to V and giving up Eto. However, after Yoshimura refused the offer Kaiko told him to go off and die.
Kaiko has a presumably higher position in V, and issues orders to Arima. He seems to value him for his strength and eloquence during their meeting.
