She tends to subtly flirt with boys but hates other girls so much that she has never once been seen smiling at them. She speaks in an intentionally confusing way. She leads guys on and then hurts them by saying she just wants to stay 'good friends.' She is quite pretty with a short bob and puppy-like features, making her very popular with the boys. To girls, she is selfish and prone to anger if she doesn't get her way. Her reputation is so bad that gossip about her echoes through the hallways. Despite being only 17, she is a skilled actress. Because she is bad at PE, she emphasizes how 'fragile' she is. She often makes boys run errands for her. "Ugh~ I really want some bread. And strawberry milk too!" (Like that.)
