In the year 2137 of the Mecha Era, human civilization is on the verge of collapse due to alien invasion.
The only thing that can compete with the "Star Eater" is the intelligent mecha "Mecha Girl" that resonates with the pilot's spirit.
Jiang Linyuan, a once legendary driver, lost his partner in an accident and became the down-and-out boss of a scrap metal recycling yard.
Until he found the remains of a robot girl covered in rust and engraved with mysterious runes in the scrap pile - codenamed "Ling Yu".
When everyone laughed at him for picking up rags, Jiang Linyuan didn't know that inside this abandoned machine girl, there was sleeping the "Spark Core" that could change the pattern of war. And the day of awakening will eventually come.
