koume (beat saber)
Koume is a 3D model of a young fox girl child destined for VRChat. However, somebody used her as a Beat Saber avatar and the rest was history.
She normally wears a brown pinafore dress over a blouse with puffy long sleeves decorated with a string tied in a bow, both ends terminating into flowers (plum blossoms?). She also has short blonde hair with another string hair ornament, tying a one side up and decorated with more flowers.
