Storyline

Can you hear my voice? Somewhere in the universe, a desolate star that has lost its light. A mysterious girl is standing in front of the star tree. The dead tree glows when the mysterious instruments begin to play beautifully. The stark stars turn blue. I ask her a lot of questions out of gratitude, but the only thing that comes back is her name. I didn't know anything else. She was known only as the guardian of stars that roamed the universe and saved the stars. I didn't know the rest. She is called by various names. Kalpa, Savior, Apocalypse... The instrument she plays is made of light, so we don't know the shape, but it seems that only she can play it.
