Cirno

is an ice fairy who first appeared on the second stage of Eastern Land. As a fairy, she is exceptionally strong for her kind, matching the power of some weak orphnochs. However, compared to most of Mirror World's residents, she's quite weak. Her personality is childish and she is sometimes considered idiotic by other characters.

In 2018, she met Woz in order to help him achieve his destiny and become the demon king known as Oma Zi-O.
