Vanguard's Hidden Base

Located on the south side of Sukai Karakura, Vanguard have their base is hidden underneath a massive white colored square building. The main front is used to handle diplomatic issues, paperwork, meetings with world leaders, and assigning new special powered humans and Shinigami to the sections of Earth they'll patrol, and discussing matters on how to deal with the imminent hollow invasion.

Their barracks, however, looks like a typical Gotei 13 squad area thanks to them using special holograms to make the ceiling appear to have a blue sky.
