The "Ghost of Flawless Immaculate Beauty". Final boss of Touhou's Perfect Cherry Blossom and later a recurring playable character.
"Princess" of Hakugyokurou, the netherworld pagoda, whose power to invoke death drove her to suicide when she was human, only to end up in Gensoukyou without any memory of her past.
Despite her tragic history, fanworks portray her as a rather ditzy airhead, seemingly thinking of nothing but anticipating her meals, sleeping, and teasing her straight-laced bodyguard and gardener, Konpaku Youmu. All these, however, conceal an incredibly sharp mind and a sense of responsibility where her powers are concerned.
Non-ghost depictions of her can be found under Saigyouji Yuyuko (living).
