Daiyousei Rule 34

Daiyousei is a fairy from the Touhou Project series, first appearing as a midboss in the sixth game, Embodiment of Scarlet Devil. Her name, which means "great fairy," was given by fans, as she was originally unnamed. She is closely associated with Cirno, another fairy, and is often depicted as her friend or companion. In contrast to Cirno's brash and childish demeanor, Daiyousei is typically portrayed as more mature, calm, and level-headed, though some official works show her as extremely shy around anyone other than Cirno. Visually, she has green hair styled in a high side ponytail with a yellow bow, and her eyes are usually blue or green. She wears a white collared shirt with puffy short sleeves, a yellow ascot, and a blue vest with a matching skirt or a blue pinafore dress. She is frequently drawn with white fairy wings, the most common wing type among Touhou fairies. Fan artists often focus on her friendship with Cirno, her serene personality, and occasionally exaggerate her figure based on her fan-given name. Her ability, revealed in a later work, is to swim through mist, though its exact nature is open to interpretation.
