The Last Glow of Blue Star

In 3033, humanity on the Blue Planet can travel through the stars by piloting spaceships. They have established the Blue Star Human Federation and embarked on a path of interstellar colonization.

In the universe, the Yanxing Federation of Planet B52, also known as Bai Liu Star, was among the first to colonize space, amassing vast human and material resources. Sensing the threat posed by the Blue Star Human Federation, it decisively launched an attack.

The Blue Star Human Federation had far fewer resources than the Yanxing Federation, and was soon routed. The entire federation subsequently collapsed.

With the Blue Star Human Federation dissolved, all the planets it had colonized fell under the control of the Yanxing Federation. Humanity was enslaved, its people reduced to the lowest of the low.

To save humanity's fate, humans who had been hiding in the shadows formed the Afterglow Alliance. Joining forces with scattered human communities across the universe and other planetary races enslaved by the Yanxing Federation, they began their struggle against it.

Lan Yu was born on Planet Limaka H23, at the edge of the Yanxing Federation's interstellar territory. As a hybrid of humans and the local Limaka people, he was born exceptionally strong and gifted with a remarkable ability to learn. He mastered the Yanxing Federation's common tongue. Since his family was killed by Yanxing Federation soldiers when he was young, he has harbored a desire for revenge. By chance, he encountered a scattered force of the Afterglow Alliance and joined it, setting out on the path of resistance against the Yanxing Federation.
