Cogimyun is actually a member of the Sanrio characters, whose identity is surprisingly unknown to many.

She debuted as a member of the Sanrio characters in 2015 and is a fairy girl made of flour.
She has a very ephemeral nature, scattering easily at the slightest disturbance. She actually wants to become a rice ball, but she doesn't know what that is. (Being a flour fairy makes it a bit difficult to realize that dream.)

Her special skills include sewing and finding little joys in life.
She has a mysterious pet that looks like a fried shrimp. Many of her friends are food fairies (?) related to flour.
