The living area is exactly that, the area where you will live.
There are two areas to this place: The rooms where you will all live and a hall that leads to the bathroom.

The rooms:
Every member of this squad, regardless of what seat you're in, gets a room in this place. You don't have to live here, but I just want you to know that you have somewhere to go if you get kicked out of wherever you're staying.
There is a couch, a bed, a desk, and an empty bookcase in every room.

The Bathhouse:
After the annoyingly long hallway, there is a bathhouse exclusive only to members of the 2nd Division, I myself will sometimes be here as well!
There are 3 areas to this place: The sauna, a hot spring (Divided into men and women sections) and some private showers, for those who are uncomfortable with bathing outside.

Use this area as you will, as it was built for you all to relax . Let all that tension from work get off your back so you may perform your jobs even faster and more efficient than you usually do.
