Chiyuri Kitashirakawa

During Phantasmagoria of Dim.Dream Chiyuri wrote an invitation flier with promises of wishes being granted to lure people to the "ruins" (which later turned out to be a ship). After pitting the various heroines against each other so that only the strongest one would make it inside, she drew a gun on the surviving heroine to force her to cooperate because it was more fun that way. This turned out to be completely different from how Yumemi had wanted the situation handled, and Chiyuri was forced to fight the heroine so that Yumemi could collect research data about magic. Chiyuri was defeated much sooner than Yumemi had expected. Chiyuri is currently believed to still be in Gensokyo along with Yumemi after her professor was kicked out of the Academy, because of the final ending of Phantasmagoria of Dim.Dream. In Chiyuri's own scenario, she is a native inhabitant of Gensokyo who can use magic, and is one of the many heroines who fight each other to gain access to the ruins. Inside, she is confronted by herself from another world, fighting with her to decide who's the stronger one, and goes on to battle Yumemi, who wishes to study her magic. This is, however, confusing.
