Daiyousei (Drillimation)

Daiyousei (大妖精) is a fictional character in the Touhou Project series of video games by the Team Shanghai Alice branch at Drillimation Studios, making her debut in the 1992 game Touhou 6: The Embodiment of Scarlet Devil. In the games, she is a greater fairy who lives around the Misty Lake near the Scarlet Devil Mansion. Like other fairies, she's cheerful and mischievous, simple and emotional. Little is known about her.

Concept and Creation
In response to questions from fans, ZUN revealed some hints about her such as "Ordinary fairies are weaker than humans. Greater fairies are mightier than other fairies." Cirno is said to be a very special exception in the 1995 game Touhou 9: The Phantasmagoria of Flower View, but according to this, "Greater Fairy" seems to be a generic term for some mighty fairies, although it's usually regarded as a personal name. She's said to be one of the normal-enemy class (not boss-class) characters.

Appearances
Daiyousei has only appeared in two Touhou games so far, the first being Touhou 6: The Embodiment of Scarlet Devil, and the second being the 2000 game Touhou Mythologies: Fairy Wars. She has also appeared as a DLC character in the iOS, Android, and Hyacintho remake of Driller Engine Grand Prix 2x2 along with Cirno.

Reception
Daiyousei generally received average reception from critics. In many fan-fictions, she's described as Cirno's senior (usually; they aren't related by blood). In the Nintendo Power strategy guide for the game, it is said that Daiyousei is Cirno's mother. This is false, as Daiyousei and Cirno have different blood types and that Daiyousei isn't an adult and married. In these fictions she is depicted as timid, shy and very kind, especially to Cirno, although still weaker than Cirno. According to some fans, she is sometimes regarded as the elder or leader of all of the fairies living around the lake.

Many fan works interpret "big fairy" or "greater fairy" as meaning having noticeably larger breasts than other fairies or just having large breasts in general. During the North American localization of the SNES version, Daiyousei's breasts are smaller than the Japanese version, due to Nintendo of America's policies regarding sexual content and nudity.

A couple of critics from GamePro and IGN call her Dai-chan due to her confusing and difficult-to-pronounce name, and was sometimes spelled "Dieyousei" in GamePro reviews.
