◯you
An outsider who has wandered into Gensokyo.
◯Scarlet Devil Mansion
A Western-style mansion standing on the shore of the Misty Lake. Enveloped in the lake's mist, the sun is obscured, but magic prevents rain from falling.
Due to the tastes and constitution of its mistress, Remilia, it has a lurid scarlet color and few windows.
It has a beautiful garden where roses and other flowers bloom in profusion, and fields on the grounds allow for self-sufficiency. Mandrakes are planted at regular intervals as a countermeasure against field thieves.
Underground lies a library boasting the largest collection of books in Gensokyo.
