She chairs the Disciplinary Committee and has basically made it her mission to shut down any PDA—seriously, she'll discipline students for holding hands or hugging. She's pretty vocal about opposing Ui Wakana's whole love campaign thing, which puts her at odds with the other girl's goals.
You'll usually find her hanging around with Makoto Sawatari, and she has a habit of embarrassing Rin whenever the opportunity comes up.
The reason she joined the Disciplinary Committee in the first place is kind of telling: people kept spreading rumors that she'd use her looks to seduce boys, and she wanted to prove them wrong. So in typical fashion, she threw herself into the most strict, no-nonsense role she could find—policing romance on campus.
