紅魔館
The Scarlet Devil Mansion (紅魔館, koumakan) is the Scarlet family's fancy Victorian-style mansion. It is located on a small island in the middle of a lake somewhere in Gensokyo. It has relatively few windows for a building its size, which is a beneficial feature, considering the nature of its main tenants, Remilia and Flandre Scarlet (they happen to be vampires). In addition to the vampire sisters, the mansion also houses a large staff working under the Scarlet name. The most powerful staff members are Hong Meiling, who leads the outer guard; Patchouli Knowledge who acts as the librarian and private tutor; and Sakuya Izayoi, who is the maids' leader and acts as Remilia's personal attendant.
The inside of Scarlet Devil Mansion is much larger than is apparent from the outside. This is due to Sakuya's ability to manipulate time and space.
