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. His attire consists of a beige vest over a black long-sleeved dress shirt, a red ribbon tied into a bow around the collar, beige pants, and plain brown shoes.
