『Tarumi』

Shimamura's best friend in elementary school. She and Shimamura called each other"Shima-chan" and"Taru-chan", but became distant as a result of attending different junior high schools. The two happen to meet again in the winter of their first year of high school with the hope of restarting their friendship. She has a reputation as a delinquent because she often skipped school and wandered around in junior high.
