The Royal Guard (王属特務, Ōzokutokumu; "King Subordinate Secret Service"), also known as the Zero Division (零番隊, zerobantai) is an organization which is dedicated to protection of the Soul King, otherwise known as the Grand Supreme Kai, the royal family, and the Soul King Palace.


The Royal Guard is a special organization that performs services for the Royal Family. It has a considerable amount of fighting, organizational, and executive power compared to other organizations. They are also charged with slaying Hollows, though the circumstances under which they do so are unknown.

Serving the royal family being the primary purpose of the Royal Guard, they don't interfere in Gotei 13's affairs and defense of Soul Society, as seen with major threats like Arrancar. They are known to do whatever is required by order of the Soul King.

The Royal Guards authority supersedes the authority of all within Soul Society. Each member of the Royal Guard have had the power of the Ōken imparted onto their bones by the Soul King. They also each have a city of their own at the Soul King Palace.


The history of the Royal Guard is not commonly known due to their status as a secret organization.


The Royal Guard serves as guardians with the primary responsibilities of:

  • Protecting the Soul King.
  • Protecting the Royal Family.
  • Slaying Menos class Hollows
  • Protecting the Royal Palace.


The Royal Guard commonly stays within the Reiōkyū. When they travel, their preferred method of transportation is a huge pillar called the Tenchūren (天柱輦, Heavenly-Pillar Palanquin). This pillar enters from the inner dimension and lands with significant force upon its arrival. The Tenchūren, however, does not have the ability to return to the Royal Palace on its own.
