Mitsuru Kotokura (言蔵 美鶴) is a girl that works at the shrine. Very polite and can appear emotionless and doll-like. She is a very good cook and is good at housework. She has the power to create invisible barriers. Tamaki, when caught in her barrier at one point, comments that it feels like mizu-ame ( a kind of syrup)
She seems to have feelings for Shinji, but it turns out that she is Shinji's twin sister.
