The Bodyguards (護衛者, Goeisha) are Katahara Metsudo's personal army. They are the Chairman's shield, and together with the Fang of Metsudo (currently Kanoh Agito), they form half of the force that keeps Metsudo in power. They also serve as a pool from which Metsudo will choose his next Fang.
The Bodyguards are a massive institution for a personal army, numbering at 500, and they are divided into eleven squads, each of which is led by a captain. Rank-and-file bodyguards are usually tasked with security detail; in the tournament, they also provide surveillance to ensure compliance with the rules. Each of the Bodyguards can easily match an average Kengan fighter in combat, though the Annihilation Tournament fighters can hold their own against them.
In addition to the eleven squads, there is a special task force called the Extermination Force. This team of four is led by Katahara's son, Retsudo, and they are reserved for special assignments. Each member of the Extermination Force can easily outdo a Bodyguard captain.
Finally, Metsudo has two personal bodyguards that protect his person: Omori Masamichi and Takayama Minoru, who are the fourth Fang of Metsudo and the closest contender to become the sixth Fang of Metsudo, respectively. Together with Kanoh Agito, the current Fang of Metsudo, they are known as the "Three Crows".
Most of the Bodyguards were orphans, who were taken into Katahara Metsudo's tutelage as children and trained to become fighters, with only the strongest being hired as Bodyguards. However, there are some rare exceptions, such as Yoshioka, who joined the Bodyguards as an adult and previously worked as an assassin.
The Bodyguards all dress in flat black suits, white shirts, and ties. Several captains and Extermination Force members have unique accessories to distinguish themselves.
