Nomo no Kuni

A girl named Sora, who once loved to sing, becomes afraid to do so after a traumatic event, eventually losing the ability to sing and laugh. With her younger brother Daichi, she discovers a pond called Kagamiike, where she sees a glowing butterfly that stirs something within her. When she tries to touch it, she falls into the water, followed by Daichi. On the other side of the pond lies The Land of NOMO, where they meet a girl named Rococo. Together, they begin an adventure, during which Sora confronts emotions she has long kept hidden.
