Uzuki Toune♀

Since her ancestors have been serving Yuuto's family for a long time by tradition, she has always been with Yuuto since childhood. She always wears maid uniform at home and is very devoted to taking care of Yuuto to the point of never allowing him to work. She also loves to tease him and sees him as real brother rather than her master. She loves idol and suddenly tries to become one right after entering same high school as Yuuto. She says it's for attracting attention to restart the inn business using their residence which their family used to run before it closed down due to Yuuto's parents' sloppy management. She is perfect maid and idol except for her singing is catastrophe.
