"I was thinking of being together with you all day, being tempted by you, and enjoying my youth with you, Onii-chan!"

She is a 1st year at Kazami Academy and has no club affiliations. She is Yuu's younger step-sister.
She has a baby face based on the appearance of her age.

With an extremely cute personality, she is a mature honor student who is liked by everyone.
She makes sure to be responsible for all the housework in the Toono Household.

There are times when she acts cheeky towards Yuu, but she has a severe brother complex. She'll indiscriminately love any appeal he has.

With her older brother desperately working hard for his own sake, she wants him to live a better school life---an enjoyable youth.
