Daiyousei | Donmai

Thought to be friends with her, portrayed as more mature and coolheaded than other fairies. In Oriental Sacred Place, she was portrayed as incredibly shy, hiding from anyone that wasn't Cirno. The Fandom might draw her with larger breasts than any other fairy, thanks to her fan name.

She has green hair in a high side ponytail tied with a yellow hair bow and her eyes are usually either blue or green. She wears a collared white shirt with puffy short sleeves, a yellow ascot, and either a paired blue vest and blue skirt or a blue pinafore dress. Out of all the Touhou fairies, she is most frequently depicted with white fairy wings.

In Whispered Oracle of Hakurei Shrine, her ability has been revealed as "to swim through mist". Whether this means she can move through the mist with incredible ease, as if she's teleporting through them, or her "swim through mist" is more akin to "thrive in the mist" and become stronger in the mist is up to interpretation.
