The Seventh Heroine in A Christmas Kiss ss

A lost girl with no sense of existence. Being very afraid of students, I seldom get in touch with other students. Exclusive desire, strong desire to dominate, unyielding, no matter what the situation has an explanation. Although I like the protagonist, I usually look at him silently. If I decide to start, I will become quite bold and positive. It is a hidden character that appears with the game.
