Kyubey (キュゥべえ Kyūbē) is a "messenger of magic" (魔法の使者 mahō no shisha) who grants the wishes of young girls, but in exchange contracts their services as magical girls. Girls who form a contract with him are tasked to defeat witches — bizarre entities that feed upon the hopes and dreams of normal people. Kyubey features prominently as a character within the entire Puella Magi series.

Kyubey is a small cat-like creature about two feet long (including tail). His entire body is covered in often clean, white fur. He has what appear to be four ears; two that resemble an average cat, pointed and up, while the other two appear as long tassel-like appendages that split into three sections at their tip. The tassels fade from white to pink and have three red dots horizontally before the splits. they also bear a pair of floating golden rings.
