A wandering performer of the cosmos, along with Aste and Mero. One day, a voice as desperate as the whisper of stars reaches them in a dream. It was the call of Kalpa — a girl sealed away alone in the heart of the universe. Your melody finally breaks the seal and rescues her, but... something mysterious has taken hold within Kalpa's body. To heal her, a sea of stars unfolds once more. What awaits at the end of this voyage? Captivating characters and an immersive story. Free Play, Multiplayer, and the ultimate Astra Mode — your performance determines the fate of the universe.
