Kazuma is a young man of around 5'5" (165 cm), weighing 120 lb (54 kg) with slightly spiky chestnut-brown hair and green eyes (black eyes in the light novel). His usual outfit initially was a green tracksuit, but later he started using an adventurer outfit consisting of a gold-trimmed green mantle, white shirt, pants, and leather boots. He wore a short sword on his belt, later replaced by his short katana, Chunchunmaru.
