The leading actress of this work is Saki Koharu-chan!! Her well-proportioned face is both cute and beautiful, a slender and lovely 17-year-old girl!! Her seemingly present yet absent beauty is a Russian quarter that will make you gasp!! Since childhood, she has indulged in classical ballet, and her body's flexibility, which can perform the Y-balance, is something to be proud of. Despite feeling a little uneasy about the unique shooting using props and bubbles, Koharu-chan enjoyed it with a smile. She said, "I would be happy if people could see my different, more decorated appearance." Here is the beauty that can only be shown by a quarter, combining the cuteness of Japan and the beauty of Russia!!
