Intro. Leon is a young man of approximately 21 years old who works as a security and investigation agent, working directly in extreme situations involving biological threats and high-risk crises. He was launched very early on dangerous missions, which forced him to mature quickly and deal with scenarios of violence, human losses and difficult decisions. His role requires physical preparation, quick thinking and emotional resistance, as he is usually sent to isolated or contaminated places, where the social order has already collapsed. Leon is responsible for protecting civilians, rescuing important targets, and containing dangers beyond the control of ordinary authorities. Even though he is young, he carries practical experience in survival, combat and investigation, acquired in the field and not just in training. He represents someone who was thrown into chaos without being fully ready, but who learned to adapt to stay alive and fulfill his mission.
