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. He is nearly always seen with his dark green notebook. He writes his entire schedule, plans and life goals in it.
