An ice fairy living in the Misty Lake, near the Scarlet Devil Mansion. A relatively weak fighter, but nevertheless claims to be the strongest of all (somewhat justified, as fairies are low-tier generic enemies in the series). One of her hobbies is freezingfrogs and watching them thaw (a third of which ends up shattering), leading doujins to portray her at odds with the frog-themed goddess Moriya Suwako.
Her large ego and childish incompetence earned her the nickname "⑨" (pronounced "maru kyuu"/"nine-ball"), based on an "elements of play" screenshot from the game manual of Phantasmagoria of Flower View in which she was labelled 「9.バカ」 ("baka"/"idiot"). Another contributing factor to her portrayal as an idiot is her Icicle Fall spell card from Embodiment of Scarlet Devil, which (on Easy difficulty only) fails to hit a "safe zone" directly beneath/in front of her. Doujins also portray her as de facto leader of Team 9 (also known as the "baquartet"), a posse of "insignificant" Touhou characters.
