Born into a family with a Japanese Mother and Russian Father in the heart of Russia, Zeren was the only child in the family due to birth complications.
At early ages Zeren was extremely adept at mathematics and some computer sciences and soon was accepted into many colleges as he exited high school. Once Zeren was on his own in the world, he decided to pay tribute to his heritage and moved to Tokyo and volunteered himself into the army. Upon entry he was considered top of his class and went through training with a will that outweighed almost all of the other applicants. Training was easy for Zeren, and even when tested he was proven to be strong.
He soon graduated from training and found himself with a dilemma, and that was integrating himself into the Japanese culture that he had learned from his mother. Every day he struggled with social anxiety and soon found himself at a dead end. The Japanese army did not pay well, and while he top of his class, the spots for good pay and housing were limited, he found himself homeless before not too long. Japan had many programs to help the homeless and one of them was medical care.
When he arrived in the building, he expected the normal to come out of the examination, perhaps a cavity or something dumb that he would have to deal with down the road. He instead found an excellent woman who reminded him dearly of his mom, after getting on his feet from the programs he started to go out with this woman and eventually proposed to her, and soon he found himself with an amazing wife.
Zeren's life was soon on track, and the army noticed, especially the SFG (Special Forces Group) in Japan. Through gruesome training he was soon given the opportunity to join, and he gladly accepted. The group was the elite, the best of the best, and he provided well for his wife, and his 2 kids. News of the outbreak was upon him however, and the group was sent along with the UN to help the infection.
He knew that he had to protect this infection, to protect the people, his parents, his kids, his wife...
His effort was soon in vain, and within weeks he found himself stranded in the province, lost, and wanting to see his kids, perhaps his wife one last time, whether or not they were dead.
