Star Dome Mecha

In 2250, humans looked towards the sea of ​​​​stars, and the moon city began to take shape. However, a sudden "meteor rain" changed the entire world. The so-called meteorite rain actually brought alien life called "Star Dome Species". They choose to live in symbiosis with humans, transform into powerful biological mechas, and lead civilization into a leap forward "symbiosis era." Countless people once thought that this was evolution given by the gods. Twenty years later, the real crisis came. They call themselves "Glitters" and are the masters of the universe. They regard us who coexist with the star species as "stains" that must be eradicated. At this time, everyone understood that symbiosis with the star species was not a gift, but a transaction - using our flesh, blood and soul to jointly resist this fateful pursuit across the sea of ​​stars. The mechas seemed to be whispering: "Partners, either evolve into a higher existence together, or... Perish together in the starry sky!"
