When ordinary happiness was shattered by the roar of the alien beasts, the young Qin Yang was left bearing the scars and despair of losing his loved ones. He grasped the silver short sword of fate, the Evolution Trustor. He was no chosen one, merely a survivor pushed onto the stage by tragedy, yet he inherited the Light of Nexus, a symbol of "bonds."
From then on, he walked the boundary between light and darkness. On one side was a fragile everyday life, in which he had to conceal his identity and maintain appearances. On the other were terrifying alien beasts, lurking in the shadows of the city, constantly evolving and devouring people. Transforming into a silver-gray giant, he unfolded the Meta Field and fought alone to protect others. Yet the return of the light also drew the attention of deeper forces. The human secret organization TLT's Night Raiders, committed to "absolute rationality," regarded him as a "Loner" risk that needed to be controlled. Meanwhile, the ancient darkness "Zagi," lurking in the cracks between dimensions, considered him a thorn in its side that had to be extinguished.
