Overview
Daiyousei is a character from the Touhou Project series, debuting in Touhou Koumakyou ~ the Embodiment of Scarlet Devil. as a Stage 2 midboss. Residing around the Misty Lake near the Scarlet Devil Mansion, she is a greater fairy whose title signifies superior strength compared to ordinary fairies rather than physical size. Although she lacks an official individual name in her debut game, she remains a prominent and recognizable fairy presence across official publications and secondary creations.
Appearance
In her sprite graphics, she has green hair styled into a left side-ponytail tied with a yellow ribbon, accompanied by blue or green eyes. Her outfit consists of a white collared shirt with puffy short sleeves, a yellow ascot or tie around her neck, and blue clothing worn over it, depicted either as a pinafore dress or a paired vest and skirt. A pair of winged appendages with distinct outer borders—resembling those of insects or birds—sprouts from her back. Her in-game pixel sprite holds four flowers of unknown type. In winter, she wears gloves and a scarf.
Personality
In official media, Daiyousei shares the standard traits of fairy nature: she is cheerful, fond of pranks, and acts impulsively based on emotion. While generally simple-minded like most fairies, she displays a more reserved and mild-mannered side compared to her peers, such as attempting to soothe Cirno when she becomes upset. In fan works, she is frequently portrayed as a rational, gentle figure who takes on a supportive role.
Abilities
Her official ability is the ability to swim through mist. Possessing greater combat prowess than average fairies, she demonstrated teleportation-like high-speed movements during the events of Touhou Koumakyou ~ the Embodiment of Scarlet Devil. Additionally, in Fairy Wars ~ Touhou Sangetsusei, she attacks by firing bullet patterns similar to Cirno's Icicle Fall.
Background
Daiyousei made her debut as the Stage 2 midboss in Touhou Koumakyou ~ the Embodiment of Scarlet Devil., intercepting Hakurei Reimu and Kirisame Marisa at the Misty Lake. She later reappeared as a midboss in Fairy Wars ~ Touhou Sangetsusei. Background characters resembling her design frequently appear in official print publications like Touhou Sangetsusei and Touhou Ibarakasen. In Whispered Oracle of Hakurei Shrine, she expresses that she does not mind lacking an official individual name, feeling that being nameless makes her seem more impressive.
Relationships
Daiyousei maintains a close friendship with Cirno, the ice fairy who also frequents the Misty Lake. In official print media like Touhou Sangetsusei, the two are depicted playing hide-and-seek together, and Daiyousei is often seen searching for Cirno whenever she wanders off. Despite not having special resistance to cold, she willingly stays by Cirno's side even in winter, donning a scarf and gloves to endure Cirno's freezing aura.
Trivia
The prefix Great (Dai) in her title serves as an honorific indicating superior strength, akin to terms like Great Wizard, rather than physical stature. She is affectionately nicknamed Dai-chan by fans. A prominent fanon running gag attributes a surprisingly voluptuous figure to her based on a play on her name. During the 8th unofficial Touhou Project Popularity Poll, her ranking fell directly between the Aki sisters, spawning the fan term Aki Sandwich.
