Sorayume Portable

Morinaga Satsuki is the sole daughter of an antique store owner, and she is an utterly ordinary second-year high school student with no redeeming qualities. It’s August 24th, and she has one week remaining of her summer vacation. When her parents leave for a business trip, she discovers a brilliant yellow ring, the “Chrysoberyl.” The man locked inside the circle was summoned into this realm when Satsuki put it on. He referred to himself as the “Ruen Egrandin” devil. He begged her to help him find the “Thing he was looking for,” promising her a “wish that wasn’t particularly a wish” in exchange. The demon sought the “Heliotrope” demon stone, which was put in another ring. “That is a destruction ring.” No matter how hard you try, you will quickly lose your head and go nuts after putting it on.” That’s the kind of terrifying ring. However, nothing horrible will happen if you do not put it on. Under Ruen’s insistence, Satsuki accepted the offer to find the Heliotrope ring without considering it seriously. From that point forward, the demon and the human would collaborate. Since meeting Ruen, or more accurately, since discovering that ring, it appears that a dream has engulfed the world.
