Biography
Not much is known about Yuji prior to his stasis. In 2009 he worked at a gas station in town and hung out with his best friend Takashi. Yuji was later diagnosed with an incurable disease that baffled doctors. As they had no idea how to treat it, Yuji was given the opportunity to become cryogenically frozen until a time where a cure could be found. Yuji accepted the offer, believing that he would only be frozen for a few years and that he and Takashi could then travel the world together.
