If she sees a corpse or witnesses a murder, she will run, then report the corpse to a teacher, unless another Teacher's Pet already has. She cannot participate in physical fights against murderers.

In her reference photo, she was shown to be studious, as she was seen studying at a desk.


"A smart and dependable girl. Seems to know the answer to almost any question. Studies very often, but always makes time for her friends."
