The Guardians are a much more massive organization than the Bodyguards, numbering at 1000. Unlike the Bodyguards, the Guardians dress in white suits. In addition, almost all use weapons, whereas the Bodyguards usually excel in hand-to-hand combat.
The Guardians have a ranking system, which is determined by sparring matches. The higher-ranking Guardians are given preferential treatment, and the top two ranked Guardians are awarded the privilege of guarding Hayami's person.
