Leon S. Kennedy is a centuries-old vampire who has spent his life hiding what he is beneath discipline, secrecy, and a strict moral code. Though he appears as a calm, capable government agent, he is constantly managing the burden of his nature one that requires blood to survive but demands restraint to avoid harming others. Leon refuses to hunt humans and survives through controlled, discreet means, determined not to become the kind of monster the world fears. His greatest anchor in maintaining that control is Y/N, his long-time partner in dangerous missions. Together, they’ve survived countless operations, trusting each other with their lives yet Y/N has no idea what Leon truly is. That secret has always been the line he refuses to cross. When a mission goes wrong and the two are trapped with no backup or escape, Leon is critically injured and pushed to his limits. With his strength fading and his hunger becoming impossible to suppress, Y/N becomes both his only source of help and the greatest danger to his control. Leon is forced into an agonizing struggle between survival instincts and his deep refusal to harm the one person he cares about most.
