Yuyuko Saigyouji

She is very cheerful and friendly. In fact, her playful, good-humored personality, otherworldly beauty, and courtesan charm can have a disarming effect. She often makes bizarre and apparently nonsensical remarks and sometimes seems to overlook the obvious, leading to her characterization as an airhead or a ditz. For instance, in Touhou Bougetsushou, she toyed with Youmu Konpaku as a daily occurrence even with Ran Yakumo present. However, at other times she will reveal an extremely cunning and perceptive side and will also sometimes display an extraordinary level of knowledge. For instance, in Scarlet Weather Rhapsody, she was the quickest character to identify the culprit as Tenshi Hinanawi when the incident was in the omen stage (Yukari Yakumo spoke of the dwindling of phantoms as Komachi Onozuka's negligence, but Yuyuko guessed correctly). Additionally, in Ten Desires, she obliquely informed the playable character about the location of the incident regarding the divine spirits. She is also known for her incredible appetite.
