Basically, the unit is certified, but Yuichi Jin, who was demoted from S-class, is currently certified as an A-class member individually as an exception. Each A-class member belonging to the headquarters has its own emblem.
Tamakoma First does not participate in the rank battle due to the difference in trigger standards, so there is no ranking.

B-class members: About 100 people (+ operators)
Unlike the A-class system, there are members who do not belong to any team. Currently, 21 teams are registered as teams and participating in the rank battle.

Basically, a shared emblem is used, which is a combination of a sideways sword silhouette and the team ranking (B-class 3rd → B-003), but teams that have experience in A-class have their own emblems because they create emblems when they are promoted to A-class.

The following rankings are the final rankings at the end of B-class rank battle ROUND 8, that is, at the end of this season (the rankings of the bottom 3 teams are unknown).
