Factions
According to Jin, there are 3 different factions in Border, each with a different doctrine:

There are also unaligned agents and teams, such as Kageura and Nasu units.

Branches
There are 6 branches in Border. Personnel that are not aiming for A-Rank are associated with a branch. They are placed on the outside of the danger zone, and act as a contact point for locals.
 * Tamakoma
 * Suzunari
 * Wataayu
 * Yumite District
 * Hayanuma
 * Hisama

Roles
Border members fight Trion Soliders who invade Mikado City. However, they are not always at the scene in time, leaving citizens to fend for themselves or if there's an agent, to fight it themselves. A-class and B-class members get paid, although C-class trainees don't.

Trivia

 * In the Viz version, it was called Border Defense Agency, which is also in Border's logo.
