Hirano is of average-to-muscular build, with bleached blonde hair and sharp blue eyes. He has pierced ears and usually wears blue earrings. His blunt way of speaking and rough mannerisms makes it shocking to see he is in fact quite thoughtful and the most motherly of them all, often taking care of his friends and juniors in whatever way he can. Hirano's personality shifts slightly when he is around Kagiura, his crush [who has confessed] he won't admit to having.
