In response to questions from fans, ZUN revealed some hints of her profile:
- Ordinary fairies are weaker than humans. Greater fairies are mightier than other fairies.
- (NOTE1: Cirno is said to be a very special exception in PoFV.)
- (NOTE2: According to this, "Greater Fairy" seems to be a generic term for some mighty fairies, although it is usually regarded as a personal name of the midboss of EoSD stage 2.)
- Like other fairies, she is cheerful and mischievous, simple and emotional.
- She lives around the lake around Scarlet Devil Mansion.
- She is one of normal-enemy class (not boss-class) characters. There are many such characters, and they are not given any special role in the story.
