A planet in the midst of a cataclysm welcomes a girl from Earth. On this planet, the girl's name is Huasheng. As the planet's physical model gradually collapses, many people awaken special abilities known as Starfighting. Monsters also appear across the planet. These monsters are called Constellations, a term referring to mutated regions or creatures. Huasheng, a girl suffering from cancer, arrives on this planet and faces its impending destruction. What should she do? What will the brother she finds on this planet bring her? What is the connection between the System Blue Cat and Mr. Wu?
