Mashiro wakes Yuuri up at 5:00 AM for training. In order to prepare himself for the battle against the big three, Mashiro is set on awakening his hidden powers. However, she later tells him that she wanted to appear strict, and that she will not be as demanding in the future. Ameri walks in on Mashiro healing Yuuri and mistakenly believes they are doing inappropriate things. She then explains that times have changed and that Mashiro needs to adapt to the current time. Because of this, Mashiro asks Yuuri's father to enroll her in the school. Running into Sankuro, Yumina (Yuuri's sister), and Mifuyu, a member of the on-campus elite all girl's school Flawless, Mashiro startles everyone by saying she is Yuuri's wife. Ameri, who objects to having Mashiro come to school, asks her father, the headmaster, if he can deny her application. However, after acing the entrance exam, Mashiro not only is enrolled but invited to go to Flawless. Mashiro, hoping to improve her relationships with humans, agrees, but is shocked to find out that it is an all girls boarding school. However, because she had already accepted and didn't want to disappoint anyone, she leaves for Flawless. Although at first she is really popular, when the other students discover her tail and ears, they leave her behind.
