Naoki is a tall blond man(dyed blond) with brown eyes. His hair is combed up in a glam rock style (mullet). He's a drummer. Teachers scolded him many times for his appearance, but he never even thought about changing anything. Takumi invited him to his Light Music Club and asked him to later be in his group (be a drummer). Naoki has a good sense of humor and seems happy most of the time.
