Kotose

The eldest daughter of three sisters working at Famille.
At work, she's mainly in charge of tea and drinks on the floor.
Like a typical eldest daughter, she's caring and somewhat meddlesome.
She's a refined beauty with graceful behavior, but she takes teasing seriously, making her an older sister worth picking on.
She likes reading and is a regular at bookstores.
She's serious about tea, even cultivating tea plants at home.
