Tenma Tsukamoto is the 16-year-old female protagonist who loves Ōji Karasuma. Tenma is short, undeveloped and childish for her age. She often is mistaken as being younger than her classmates and her younger sister Yakumo. One of her obvious physical features are the little ponytails in her hair, which often wiggle if she is happy or excited. She is also dense, slow and unreliable and often misunderstands otherwise obvious situations. Despite her shortcomings, Tenma is good-natured and friendly.
