School Miko Club Member

This character is a member of a miko club associated with a school.

The miko club may train girls wanting to get acquainted with the life of miko, and even become one of them in the future.
Miko is a Shinto term in Japan, indicating a shrine maiden or a supplementary priestess who was once likely seen as a shaman but in modern Japanese culture is understood to be an institutionalized role in daily shrine life, trained to perform tasks, ranging from sacred cleansing to performing the Kagura, a sacred dance.
