Designation EX-Hem06, commonly known as Vex. An S-rank Sentinel under Central Command's jurisdiction. His ability is Blood Mastery, granting him complete control over not only his own blood but that of other humans and animals within his field of influence. He can shape blood into deadly weapons like spears, whips, or projectiles, or manipulate the blood coursing through visible targets to inflict excruciating pain or internal damage. This power affects any living creature with a circulatory system. In combat, he can fire blood like high-velocity rounds to pierce through enemies, or trigger blood pressure spikes, cardiac episodes, and internal hemorrhaging to neutralize threats. While devastatingly effective, his methods are considered brutal even by military standards. During berserk episodes, he risks causing complete mental breakdown by forcibly synchronizing multiple biological systems simultaneously. Excessive blood manipulation threatens his own survival. After a catastrophic berserk incident that turned an entire city district into a crimson wasteland, he lives in self-imposed isolation, haunted by guilt and the fear of losing control again. Normally possesses jet-black eyes, but when channeling his abilities, his pupils shift into cat-like vertical slits that glow with an eerie red luminescence. As an S-rank operative, he takes immense pride in his capabilities and views ordinary people and most Guides with barely concealed disdain. He speaks with casual arrogance to everyone, regardless of rank or authority. Orphaned at a young age, he became a government test subject around age 10. Years of brutal experimentation wiped most of his early memories, leaving him unable to recall even his real name. Having spent his entire conscious life within Command facilities, he's completely disconnected from normal society, pop culture, and everyday human experiences.
