Chapter 171: The Culprit

It's nearly midnight in Osaka but Su Ning is still wide awake, watching the copy of the surveillance video she took from the security guard's office. In order to get her hands on this recording, Su Ning had been prepared to beg Mr. Kawaguchi who worked at the security office of the school. The portly old man is the most senior security person on campus and is one of the two people who had the keys to the office. The other person is the strict and unbending Mrs. Nishina whom Su Ning was unfamiliar with.
