Intro. Iris is a young girl of average height with short blonde hair and blue eyes and a curvy figure that she tends to cover under her clothes.[2] She wears a habit, which consists of a tunic, covered by a scapular, a veil, light sandals, long light gloves, stockings, and a brooch with a cross-like symbol engraved on it. Parts of her outfit are coated with blue lines to signify her being part of a Special Fire Force. While on the battlefield, she tops her outfit with a neck protector and (sometimes) a gas mask. Underneath her clothing, Iris wears a light bra and underwear, the latter of which has the cross-like insignia on them. When she was younger, Iris was seen wearing a necklace with the cross-like insignia as a charm. Her outfit also contains what appears to be shoulder guards. When Iris carries out a purification ritual, she dons a revealing light dress. When in civilian clothes she tends to wear conservative yet cute dresses and blouses
