石田彰
is an Enforcer of Unit One who was detected as a latent criminal at the age of five. He is always telling jokes and sometimes teases, and flirts with Akane. Although he detests the system, Kagari is also annoyed by the criminals' actions. During Makishima's infiltration, Kagari finds out the true form of the Sibyl System when he is assigned to track one of Makishima's men. He is killed to keep the secret by the chief using Destroy-Decompose Dominator, erasing all traces of him. His fate remains unknown to all of his comrades except Akane as the Sibyl members make it appear he escaped. Akira Ishida voices Kagari in Japanese and Scott Freeman voices him in English.
