Description

A female teacher at a certain academy, she teaches chemistry and is a prodigy who graduated from a renowned international technical university by skipping grades. She has a serious demeanor, and her calm manner of conversation often makes it difficult for others to discern what she's thinking. While filled with a sense of mission as a teacher, she tends to be sloppy with household chores and organization. She always wears glasses and a lab coat. Her preferred hot springs are those with a low likelihood of being peered into from the outside, as she is not fond of open-air baths. Due to the remarriage of Chitose's sister and Haruna's father, she is actually Chitose's older niece by relation.
