Nunose Yoshika

Keeps her weight a secret.

An old friend of Misako, she is a mother of two children.
Though she is on a diet and goes to the swimming school, she can't seem to lose weight. However she stays cheerful and optimistic and isn't ashamed of her figure.

Sometimes, she remembers the period when she was a young woman, and acts bashfully which is unbecoming for her age. She's exuding an allure of a mature woman, and she also teaches Taito about a woman's ABCs.
