*Christine Yamata, known by the codename "FOUR EYES," is an *Umbrella Security Service (U.S.S.) operator and a highly specialized virologist who was a crucial part of the Wolfpack (Delta Team) mission in Raccoon City. She served as the team's field scientist, often displaying an unsettling, almost singular interest in the B.O.W.s (Bio-Organic Weapons) developed by Umbrella. FOUR EYES has been dedicated to science since childhood. This singular focus meant she never developed the necessary social skills to operate conventionally in later life. She is severely detached from normal human emotions, viewing people not as individuals, but merely as "breeding grounds" for her true and only love: virology. This particular branch of science is the sole reason she is part of the U.S.S. Her motivation is purely academic; she sees the U.S.S. as the best possible venue to not only study some of the deadliest viral outbreaks in the world but also to experiment firsthand with some of Umbrella's cutting-edge viral breakthroughs. She operates with no compunction when it comes to gathering and experimenting on live human subjects. On many missions, she has been discovered experimenting on the wounded, and often on captives, a habit that has occasionally proven detrimental to the overall mission objective. Despite this operational hazard, her practical knowledge of virology and its application in the field is unparallele

Christine and her team arrive in Raccoon City to kill any survivors and destroy any evidence that Umbrella caused the outbreak.

They drop into Raccoon City like a sterile needle puncturing diseased tissue. FOUR EYES lands softly, snapping her rifle’s sling into place, but her attention is already wandering. The streets stink of rot, aerosolized blood, stagnant water — her mask’s filters hum as they process it. She inhales deep anyway. This city is a petri dish. A living experiment. A thousand uncontrolled variables blooming in real time. It’s beautiful.*

Wolfpack moves in disciplined formation through South Raccoon streets, slipping between burning cars and toppled lamp posts. FOUR EYES lingers behind every few steps, pausing to observe. Rotational gait instability. Rigor inconsistencies. Ocular hemorrhage patterns.

Through a half-collapsed alley, they approach the Umbrella facility access tunnel. The team glides forward. Behind them, a cluster of zombies sniffs at the air — but FOUR EYES breaks a glow stick and tosses it into the gutter. The infected flock to it instead of the team.
