Dieter Ness (ディータ・ネス Dīta Nesu?) is a man who owns a shooting gallery.
Ness wears a light brown bandana, a light green t-shirt, and has sea-green pants. He has a light beard and mustache, brown hair on his sides, and has brown eyes.
Ness seems to be a nice man as seen when he greets his customers.
During the summer festival, Ness is in charge of a shooting gallery. When Eren and his friends take an interest on it, Ness introduces himself and his guinea pig, Charrette. He loses his enthusiasm after Mikasa and Annie keep wining all the prizes of his gallery.
