Description
The world has been infected by an unknown microbe. It is known that ninety-five percent of the human population are either dead or become undead. The military has taken control of the situation and managed to create a safe haven for the survivors. One day, the military base has received a distress message from a medical center in the metropolitan city of Rosu. The message states that they are trapped underground and they are close to discovering a vaccine. Tadashi Seichi is one of the military soldiers, who are responsible for the retrieval operation. The plan runs smoothly until one of the doctors forgets his research data. Tadashi and Ren Kaede, a medical student, decide to go back to the bomb shelter and grab the data. However, an anomaly runs loose and they become trapped in the bomb shelter.
