Doppo is a tall young man of medium build, with blond hair and grass—gray eyes. His bangs are directed to the right, and his hairstyle is quite neatly braided into a long ponytail, but still has protruding hair. He always wears glasses. His clothes consist of a beige vest on a black long-sleeved shirt, a red ribbon tied around the collar, beige trousers and plain brown shoes. Doppo appears to be a very serious, but slightly short-tempered young man.
