What happens when the group of armed men enters the classroom?

During one of Ofunne's first university exams, a group of armed, muscled men, enters the exam hall. One of the men touches Ofunne's breasts, and promises to protect her if she agrees to sleep with him. Outraged, Ofunne defends herself, slinging a series of insults at the man. The man becomes angry and accuses her of cheating. The sitting professor makes Ofunne complete a malpractice form.
