Umi Astra, a fallen star, has returned to the sky with a sole mission - to find her family. But among 88 constellations and trillions of stars, how will you find just one? In a world of creatures representing the stars themselves, where the Zodiac rules over people separated into sectors, where your status is set by how bright you shine for others, who will reach out a helping hand and who will find personal gain from your journey? Oh, and there's one other problem.. Just who was Umi in her past life?
