Kaiko (芥子) is a ghoul and a member of the mysterious organization called the V.
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 of V, and is targeting Eto due to disrupting the stability of Ghouls and Humans.
Not much is known about Kaiko's past other than he used to know Yoshimura before he left their organization.
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.
