Headquarters

Headquarters is the Sailor Senshi's secret base.

About
Headquarters is the Sailor Senshi's Command Center which is located under the Game Center Crown. At the arcade, Luna presses buttons in a sequential order on the Sailor V game, and the machine slides back to reveal a staircase underneath which leads to a highly advanced base. She explains that this is a secret base that she uses to research on the enemy. It has a powerful shield so it can't be detected. If an intruder enters an alarm will sound.
