Narumi has long, grey hair tied into a braid worn over her shoulder. The braid is held by an aqua bow to match the clip she wears tucked behind her short bangs. On the left of her head she is a single, curling strand of hair let loose. She has soft blue eyes. Her outfit consists of sheer black fabric with aqua material covering the chest and flowing like a cape with white gradient. It is cut to reveal a black pleat skirt beneath a white flower-shaped peplum lined in aqua to accent the aqua and white lining on the skirt. On the waist is a gold belt with aqua gems and two large white flower petals hanging from the middle, dotted in orange. White and sheer split fabric covers both the arms and legs, decorated with black strips to match the black strips sewn around the outfit, some of which have azure glowing lines. She also gains pale blue wrist accessories, a flowery collar with a gem ornament, and a matching hair piece. Haruka is a calm, collected and polite girl that's not afraid to show her smile. She remains strong and tough during battles and sweet and kind in school. She refers to herself as "Narumi", meaning she puts her last name first, which is a sign of her maturity. She aspires to become a doctor when she is is older. Despite her kind and gentle disposition, she has an interest in violent, action-packed shounen manga.
