V

V (read as five) is a domestic gifted underground syndicate that operates in Japan, whose goal is to rid the country of ability users.

Description
They are an organization of ability users that banded together to get rid of other ability users in Japan. According to then assassin Sakunosuke Oda, the group kills for justice and, once finished doing so, shall only continue to kill indiscriminately.

V's range of influence is unknown, though the organization owns a shell company posing as a shipbuilding company's office.

Structure
As mentioned by one of V's members, Jun Mitamura, V is apparently led by a boss and certain higher-ups. They were also able to employ foreign ex-military guards in their attempt of capturing Sōseki Natsume in their Theatrum Mundi strategy.

Untold Origins Arc
Sometime after the war, V was responsible for using Theatrum Mundi actor Tokio Murakami and playwright Kurahashi as pawns for their large-scale scheme of kidnapping Natsume, an ability user under the government's witness protection program. They issued a declaration to the theater days prior the theatrical run of the play The Living World Is a Dream, the Nocturnal Dream Is Reality, which read:

"An angel shall bring death, in the truest sense of the word, to the performer. —V"

One of their members, Mitamura, nearly succeeded in abducting Natsume after incapacitating him, only for the young detective Ranpo Edogawa to expose Natsume as a victim and Murakami, who was executing Kurahashi's scheme at V's behest, to the theater audience. Upon the failure of their plot, V assigned Mitamura, who was operating as a uniformed city police officer, to bring in Ranpo for derailing their plan and persuade him to work with them. This also ended in a failure after bodyguard Yukichi Fukuzawa overpowers Mitamura and his five cohorts with the help of Ranpo's deduction.

In the aftermath, Mitamura was arrested but later found dead from being stabbed by an invisible force, which was assumed to be V's action to silence him.

Trivia

 * In the anime, Fyodor Dostoevsky shows knowledge about V, briefly surfacing in the aftermath of the theater incident and noting the organization's name to be read as five rather than V. V's pronunciation and Fyodor's connection to V are not included in the original light novel.
