She is a part-time swimming instructor at the school that Takeshi attends, and is an all-around sportswoman.
She is also a resident of the company dormitory where Yae and Karin live. Takeshi had never imagined that Chie-sensei was a candidate for his maman.
To begin with, Chie was the daughter of a city councilor, and was also involved in the landowner business. She was also involved in the loan shark business, and was therefore well connected to the underworld.
She is also a close friend of Masuzoe Seira and Mishima Sae. Her Somber expression makes it difficult to tell whether she is a good person or a bad person, but she is surprisingly loyal and has a strong sense of duty,
Her motto is "Be strict with others and strict with yourself."
