S1·E21 Piano yo Hibike Hoshizora ni/Echo the piano in a starry sky

Gentle and ladylike Yuri starts hanging out on the streets with a rough group of girls and is evasive when her friends ask about it. Eventually the truth comes out and Yuri explains that she is trying to help her old friend, Hitomi, who seems to have lost her way in life after the death of her older sister. Yuri orchestrates an elaborate production with her friends in an attempt to get Hitomi out of her rut, but the devil Sandra finally decides to make an appearance in the human world and attacks Hitomi before things can get started. Fortunately for Yuri, when you're a Love Angel, sometimes miracles happen.
