Tenma Tsukamoto  

, 塚本 天満

The female protagonist of the story is named Tenma Tsukamoto. She has a love interest in Ouji Karasuma. Although she appears to be young for her age, with small stature and childish behavior, she often gets mistaken as being younger than her classmates and even her sister Yakumo. One of her prominent physical characteristics is the little ponytails in her hair that wiggle when she's happy or excited. Despite these shortcomings, Tenma is a kind-hearted and friendly person.
