"With courage, you can overcome any hardship. Tired sayings like that don't provide much comfort in reality. All I could do was sit quietly and be thankful for my own, sad life..."
Yoko Suzuki is a former Umbrella employee and a survivor of the Raccoon City Destruction Incident. A "self-proclaimed" university student with good computer knowledge, Yoko has a quiet, reserved personality, but the strength of her inquisitive mind emerges with a surprising toughness, making up for her absentmindedness brought on by thinking too much analytically.[excerpt 1]
Born in the United States, Yoko is the daughter of Japanese immigrants. As a teenager, Yoko was hired by Umbrella and worked at the NEST, headed by Dr. William Birkin. Her specific role in the company is unknown, but she was familiar with both the Hunter and Tyrant Projects. In 1996, Yoko donated tissue cells for use in t-Virus research.
Over time Yoko became a burden to the staff, with fellow employee Monica describing how she got scared and ran away. Dr. Greg Mueller operating on her to wipe her memory of working at the facility. It is possible, however, that Yoko continued to work for the company in a more legitimate capacity, as she continued to wear an employee uniform for two years.
In September 1998, Raccoon City's drinking water was contaminated by a modified Epsilon strain of t-Virus, resulting in tens of thousands mutating into Zombies. On 24 September, Yoko entered Jack's Bar as usual and began cutting her hair in the women's restroom. There, she was attacked by a Zombie trying to grab her through a vent.
Little is concrete about Yoko's exact whereabouts after her escape from Jack's Bar. It is known she found here was back to the Underground Laboratory, where she ran into Monica, who believed she was after the G-Virus. Yoko was able to reach the top of the facility where a train was located, but found herself confronted by a "G" which had killed Monica along the way. Though she took the train out of the industrial zone, she could not escape the city itself.
During her experience of the disaster, Yoko slowly regained her memories of the event and, by the time the city was destroyed on 1 October, she understood everything. After escaping Raccoon City, Yoko went on to testify against Umbrella in court with Dr. Linda Baldwin, a woman she met at the Umbrella R&D Center.
