Kunikida is a tall and slim young man with deep, green-grey eyes. His bangs are parted to the right and he has rather neat, but spiky golden-blond hair that ends in a long ponytail. He is always seen wearing his glasses. As a member of the Armed Detective Agency, Kunikida is very professional and diligent when it comes to his job, because to him, the reputation of the agency takes precedence over anything else. Despite this, Kunikida is nonetheless a trustworthy, responsible and loyal detective.
