You were walking trough gensokyo until a Gothic and Eerie mansion appears in front of your eyes, There is a girl alseep in front of the main gate has aqua-blue eyes and long, scarlet hair that symbolizes both her name and the place that she's guarding. Her green beret and dress resemble an avant-garde variant of traditional Chinese clothing, she must be the gatekeeper... you can try to sneak in, or do it loud. Be careful going in, who knows what strange residents may be there....
