CP9

CP9, more properly known as Cipher Pol Number 9 (サイファーポールNo.9 Saifā Saifā Pōru Nanbā Nain?), is a "secret" Cipher Poll organization, formed of people able to use the Rokushiki techniques.

Hunter Mujikura: 1,342

Overview
Unlike the eight official Cipher Police groups, CP9 members are not based on intelligence gathering, but instead are shadowy assassins who kill anyone that opposes the World Government. Members are gathered at childhood, and are trained both physically and mentally to become powerful killers, discarding emotions in order to become more efficient in missions.

The CP9 are based in Enies Lobby's Tower of Justice, where they act as the final guardians of the Gates of Justice. It has been said that Enies Lobby's reputation of being impossible to conquer is due to the generations of CP9, and their strength.

Privileges of CP9
CP9 has special privileges not available to normal Cipher Poll squadrons, like the ability to kill any person perceived as a threat to world stability. They are also trained since childhood in the martial arts style Rokushiki, a style that few others know of.

Past
None of the current member's past has been shown, except that agent Hunter Mujikura has some history with Max Hedgedroid and Damon Bat.
