Headquarters

The Headquarters (本部) is the main facility of Border, run by Masamune Kido.

Base Layout
The base has a rather complex layout, as it can be customized as needed due to the fact it's powered from a Mother Trigger. This is seen most of all by Kinuta reinforcing the walls after Chika fired through the wall with an Ibis rifle. It also has various rooms large and small, including the Operator Rooms, the Holo-Display room, the Board Room, the Sniper Range, and more.

Since Izuho brings her cat in there and Yotaro brings Raijinmaru, it's clear that animals are allowed in the building.

Solo Rank Wars Booths
Used by various agents of all ranks, these virtual simulation rooms allow a safe space to train and refine your skills to become stronger. Hyuse complimented the technology, and suggested it's Border unique; or at least, Aftokrator does not have it.

Operator Rooms
Each squad has their own operator rooms (the C-Rank unit doesn't count as an actual squad). A-Rank Squads have more space (complete with a kitchenette) and therefore more ability to customize their Operator rooms. When agents bail out, they typically head to these rooms, although not all of them are at HQ, namely the branch offices. If they bail out inside the base, there are a series of vents that will take them to the Operator room of their squad.

Holo Display Room
The room seen when the higher-ups meet with Yuma about information on the Neighborhood, where they have a holographic projection of the map of the Neighborhood. It is currently unknown if they ever use the projection for anything else, but it's set up so that there are rows of seats on three sides, with the holo projector in the center. Due to Replica's update, it houses a great deal of information gathered by Yugo Kuga, Yuma's father.

Sniper Range
Called the largest room in the base, it's where the Snipers, especially the trainees, go to train and rank up. It's also where Chika blew a hole in the wall firing an Ibis.
