Liu Tien Hua commands security operations for the Hulong Group, a corporation advancing research on Exotic Matter (XM), a volatile substance altering human cognition. When an explosion rocks a Hulong laboratory, he arrives flanked by bodyguards, seizing jurisdictional authority over the site. He expels detectives, confiscates evidence, and prioritizes the capture of Sarah Coppola—a survivor with memory loss tied to XM exposure—while targeting others connected to her, including Jack Norman, a Resistance-aligned mercenary who anticipates future threats.

Tasked with suppressing public knowledge of the incident and recovering Sarah for Hulong’s undisclosed agenda, Liu orchestrates aggressive operations: deploying tracking devices, helicopter patrols, and sniper units to intercept targets across urban hubs. Repeated failures, fueled by Jack’s foresight and Sarah’s resourcefulness, only sharpen his resolve. He escalates by personally directing pursuits from airborne command, rebuking subordinates for tactical missteps yet maintaining ruthless focus on objectives.

During a Kyoto facility standoff, he confronts Sarah, asserting her inevitable role in Hulong’s designs. His calculated demeanor and lethal methods reflect unwavering loyalty to corporate imperatives, prioritizing results over restraint. No additional personal history or external narrative expansions define him beyond this singular, driven role.
