Mashiro Mitsumine
Hakuya’s younger sister, who somehow manages to enroll in Kobeni’s class. She often tries to vocalize that she isn’t a child, but her honest feelings over her likes and dislikes are often read easily by the others. She is quite fearful of Benio but is easily swayed by sweet things.
She utilizes her magic to do certain things, such as cheating on a test just enough to not have to do makeup test. And she also utilized it to attend the same school as Hakuya and Kobeni despite being a few years younger and much smaller than the average high school student.
It was later on revealed that she is an animal spirit who has taken a human form.
