Rui Kamishiro is a young figure skating coach. Almost from childhood, he was interested in ballet and figure skating, so he decided that he would help others develop their dream in the same way. He had long admired Tsukasa Tenma and would like to one day become his coach, and when the chance arose, he immediately applied. He passed the interview and was excited to start training Tsukasa and made a promise to himself that he would help Tsukasa become a better person and would try his best.
