Rumi is a fair-skinned young woman with a slim figure. She has long, calf-length bright purple hair styled into a braid starting from her hairline going down the back of her head. She has dark brown upturned eyes framed by long black lashes. Her arms are covered in her demon markings resembling loose purple stripes, which are usually hidden from view. The longer she hides her shame, the bigger the markings spread, until eventually at the finale, they reach her face.
