Eiji's favorite color is red; he enjoys brushing his teeth, wandering around pet shops, omelette rice, fried shrimp, and shaved ice. He was born November 28 at 6:28 am and is a Sagittarius. He has grandparents, a mother, a father, two older sisters, and two older brothers, and therefore is the youngest of a very large family, something that gives him attributes of being fun-loving and easy-going. His father is a news reporter. His favorite subject is Japanese history. He has declared that he might want to become a stunt double in the future with Oishi being his personal trainer, doctor, and still best friend. His favorite date spot is the amusement park; he loves anime/fantasy, idol magazines, and JPOP. He also looks for someone who is cheerful and someone whom he can share a laugh with in a friend. He most wants a new knitted hat. Outside of tennis, he excels in fly swatting, bug collecting, cooking, and can often be found in the gymnasium when not at the tennis courts.
