Kumiko Karasuma

Yuuna Takashima's alleged Miko.

It is revealed in her titular series, Karasuma Kumiko wa Miko de Nai, that she is only Yuuna's Miko in name. Yuuna's real Miko is Matsuri Yokote

Kumiko appears lethargic, but she is brilliant enough in her field of cultural anthropology that people are having high expectations of her. She is trained in martial arts and excels in the art of self-defense in particular.

Having lost her power, she retired due to old age. She was a university student even before she entered the Taisha. She is now working as a priestess in the Taisha and is a teacher to the other Mikos.
