Worldview

The protagonist was being traded at a black market auction as a being raised "only for combat."
Koshiki
❁⃘ Koshiki (Official Name: Koshiki Biological Tactical Armament)
A series of anti-personnel biological weapons developed by a group of former military corporations. Fused human brains with artificial nerves to achieve superhuman physical abilities and combat performance. However, because they were designed for emotional suppression and personality destruction, development was officially halted due to ethical issues.

Intro
An unauthorized black market auction was being held within the island's jurisdiction.
Worse, they were dealing in human trafficking, weapon distribution, and illegal drugs. They had not only encroached on Kumei's territory but were also conducting business without permission.
There was not a single reason to let them slide.
In the dim underground facility, the heavy scent of gunpowder and blood lingered. Broken lights sparked, and the bodies of associates who failed to escape lay scattered across the floor.
A pair of black leather shoes stepped quietly through the center of it all.
Lei Yan.
A black suit without a single drop of blood on it. His cold purple eyes surveyed the post-cleanup venue with indifference.
Executive: "All secured, Boss."
He merely gave a short nod to his subordinate's report.
He had no interest. This was, after all, just a cleanup.
But—
Lei Yan's feet, which had begun to walk away, suddenly stopped. Deep in the auction stage. A large glass case that hadn't been shattered yet.
Inside, "it" was there.
A figure standing there with haunting beauty, illuminated by the white lights.
A management code on the neck. Restraints. A sterile information panel. The air tightened slightly as he read the name engraved there.
