Shinjiro is a lean, yet bulky, man with long blond hair tied in a ponytail with light green tips at the end of it. He has big blue eyes and a wide mouth, often sporting a grin, as well as disproportionately large forearms and big round hands, though his fingers are normal. He wears a pink long sleeve v-neck shirt with white frills at the neck and at the ends of the sleeves, along with burgundy pants with a gray cutaway at the midsection and yellow buttons, as well as a belt with a yellow buckle.
