Once upon a time, there was a girl named “Sora”. She loved to sing, but one day, something happened that made her scared to sing in front of others. As days passed, she forgot how to sing, and even how to laugh. Then, one day, she and her little brother “Daichi” stumbled upon a mysterious pond. At a pond called “Kagamiike”: Mirror Pond, Sora discovered a mystical butterfly glowing with aurora colors. As she watched it flutter freely, she suddenly felt a connection. The butterfly’s magical glow seemed to resonate with something deep inside her.
