Judgement Blow (断罪の一撃, Jajjimento Burō) is a special skill that can only be gained by becoming a Legion Master.[1]
Essentially being a one-hit move, it allows them to forcefully uninstall Brain Burst from a member of their legion and a former member that had left the Legion under one month ago.[1] However, it can only be used at an extremely close range as its range is almost zero. [2]
