Ganz is one of Dan's friends and former accomplices during the Dunk Mask era. He sold the parts of the TVs they vandalized. He also gave the group the idea of giving the Big Foots sandals made of tires when he brought a large amount of human-sized tire sandals for them to deliver. Haruka took an interest in him because his head looks like a foot. He is shown to be a good salesman and frequently disappears on Haruka's orders to conduct business elsewhere. In the aftermath, he is seen selling things at a store.
