Fairy

Fairies (羽妖精) are tiny humanoid beings that existed in YGGDRASIL and the New World.

Background
Fairies were among the monsters that possessed beautiful appearances.

Appearance
Fairies are small humanoid beings with a height of a little finger. They possess butterfly wings enabling them to fly.

Abilities
In the Web Novel, fairy type monsters could use illusion magic. They are confirmed to be heteromorphic beings, as spells which only affected humanoids and demihumans had no effect on them.

Trivia

 * In the Hack And Slash Adventure book, adapted by Tabula Smaragdina, fairies are one of the races players encounter.
 * The Gnator are mistaken as fairies due to their similarities; in fact, they are a predatory species that prey on fairies.
 * Fairies or fey are racial beings as confirmed by Ainz. Though it seems that the dark elves of the Great Forest of Evasha refer them to more as spiritual beings.
 * YGGDRASIL also had the concept of the Fey Blessing, though they Fey didn’t posses it naturally. Interestingly the dark elves once possessed, though it’s unclear if it’s the same concept.
