Long ago, the night sky was filled with countless constellations, and these constellations were the light that brought hope and harmony to the world. However, a dark entity, the "Lord of Darkness", appeared and swallowed up the light of the constellations. The dim night sky could no longer illuminate the world, and people lost their way in the darkness and lost hope. At this time, the star spirits that protected the constellations gave birth to the star children with their last remaining strength. The star children were beings with the power of light that could fight against the darkness, and they were the only hope to restore the light of the constellations and save the world.
