Fairy (Touhou)

A fairy (妖精 yousei) is a small, simple creature of that represents some aspect of nature. Many of them are also simple-minded. They tend to have short lives, but they will regenerate immediately after dying.

Appearance
Fairies resemble children with wings, usually mayfly- or butterfly-like, though more unusual cases exist (such as 's triple icicle wings). These wings might not be solid - in most depictions they appear to float over the fairy's clothes, unconnected to their body, and some fairies have shown the ability to hide them.

Abilities
A fairy may have abilities relating to the four seasons, weather, emotions, longevity, decay, fertility, or other aspects of nature. The power exercised by a single fairy is usually harmless and small scale, so they're more suited to playing around rather than causing major happenings. Fortunately, most fairies are easily amused by pulling pranks on unsuspecting humans. However, since fairies tend to gather in areas frequented by humans and, a large group of fairies may indicate the presence of a powerful youkai.
