Diane is a fictional character in the 2007 video game No More Heroes. She is an unseen and long-suffering employee of Beef Head who usually calls Travis Touchdown after each of his ranking matches to remind him to return overdue merchandise, a majority of which are pornographic in nature. She has little patience for Travis's procrastination and once even claimed to have revoked his membership until the return of a certain video.
