V

V, spelled with the single letter and also called Vasuki, operates entirely out of public sight, pursuing what it frames as an equilibrium between people and ghouls. That claimed balance has grown shaky, largely because of the militant faction Aogiri Tree and the figure known as the One-Eyed Owl, and the society set out to erase this movement as a threat to its design. Later revelations tie the group directly to the Washuu, and Nimura Furuta eventually explains that V itself is made up of the Washuu together with their assorted branch households.

Membership carries a strange biological signature. Recruits brought in during adulthood somehow acquire the same distinctive Rc cell pattern that natural-born Washuu develop through generations of interbreeding and cannibalism. Stranger still, that trait passes to their children even when the offspring, such as Eto Yoshimura, want nothing to do with the group. How new inductees receive this marking is never explained.

Yoshimura, born Kuzen, once served the society as a cleaner, an operative dispatched to erase humans, ghouls, and rival factions that endangered it. He fell for a human named Ukina and fathered a child with her, only to learn she was a reporter probing the organization. When V uncovered her work and their bond, it demanded he kill her; he resisted, then relented at her own urging. He soon abandoned the group and, dreading what it might do to his infant, left the girl in the 24th ward under Noroi's protection alongside Ukina's journal. Years later she surfaced by assaulting CCG Headquarters, prompting Yoshimura to adopt her One-Eyed Owl persona so the cabal would hunt him instead. Before the Owl Suppression Operation, Kaiko met him to offer forgiveness in exchange for surrendering his daughter and swearing loyalty, and the refusal earned him a curt wish for his death.

After Kishou Arima captured Ken Kaneki, V kept the artificial one-eyed ghoul under tight surveillance while he was rebuilt into the investigator Haise Sasaki. From prison, Eto used her novelist persona to publish King Bileygr, which hinted at a centuries-old pact between the Washuu and V and claimed a clash with a mighty one-eyed ghoul had birthed the CCG. Itsuki Marude dug further and concluded the Washuu were not ghoul allies at all but ghouls themselves. Eto also told Sasaki that Rize Kamishiro had fled the society and that its Rc Scan Gates ignore anyone carrying V-linked cell patterns.

Kaiko weighed with Arima and Furuta whether the captured Owl might be the One-Eyed King, ordered the killing of Rize's relative Matasaka Kamishiro, and set Furuta to watch both Kaneki and Eto. He also had Eto's editor Shunji Shiono put to death for printing the exposing book. During the Third Cochlea Raid, Furuta restarted a crushing machine on fleeing ghouls while V agents looked on, and those agents later fell to Eto's kakuja as she shielded the escapees. Kaiko then joined Uta, Donato Porpora, and Furuta in murdering Chairman Tsuneyoshi Washuu and slaughtering nearly the whole Washuu line, sparing only Matsuri.

As Kaneki assembled his group Goat, V dispatched agents styled as an urban legend serving the Washuu to crush the Nameless King's White Suits in the 22nd ward, branding both the Clowns and Goat as enemies to be destroyed. Kaiko ultimately ambushed the S2 Squad leader Matsuri Washuu, declaring the bloodline had become a liability, and cut him down. The anime frames the earlier tragedy differently: after V learned of Yoshimura's family and betrayal it moved to kill them, Ukina died as they fled, Kuzen hid the baby in an empty house, and when he came back the child had already been taken.

Its confirmed operatives include Kaiko, Kichimura Washuu, Kishou Arima, Tsuneyoshi Washuu, and Yoshitoki Washuu, with Kuzen (Yoshimura) and Matsuri Washuu counted only among former members, plus a body of nameless subordinates. The organization works closely with the Washuu Clan and the Clowns, and it is symbolically tied to the tarot card The Hierophant, numbered five.
