Sayaka Kotani

Sayaka Kotani serves as the school nurse and fishing club advisor at Umino High School. Carefree and unapologetically fond of alcohol, she has a habit of showing up at club activities under the guise of supervision — though her real motive is scoring fresh-caught fish to pair with her drinks. Perpetually short on cash due to her drinking habit, she nonetheless holds a hunting license and possesses impressive culinary skills, making her a surprisingly knowledgeable yet exasperating presence in the students' lives.
