In a quiet coastal town, a young girl named Hoshi spends her days gazing at the stars, feeling a deep connection to the night sky. She often visits a lighthouse, where she meets a mysterious boy named Riku who shares her fascination with the cosmos. Together, they discover a strange, glowing stone that seems to pulse with the rhythm of the stars.

As they investigate the stone's origin, they learn that it is linked to an ancient celestial event that occurs once every hundred years. The stone's power begins to affect the town, causing strange phenomena and drawing the attention of a shadowy figure who seeks to harness its energy. Hoshi and Riku must protect the stone and uncover the truth before the balance between the stars and the earth is disrupted forever.
