The cocoon of sound is unleashed, and after 10 years, it flaps its wings again - a new story of "PUPA" begins. "PUPA", which has carried the story on its back and colored the music game world, celebrates its 10th anniversary and undergoes a new evolution. Along with the original songs, the re-creation by a team of splendid artists and the winner of a remix contest spreads its wings of sound. Like the "chrysalis" of its name, the music has changed form, taken on new life, and evolved. This album is a new "metamorphosis" born of the resonance between music and story.
