Live in a world where 90% of humanity has perished.
About
A world where 90% of humanity has died out. You stand amidst the silence of ruins. Most of mankind was wiped out by the virus and the 'Phantom Beasts'—animals infected by it. The surviving humans, those with resistance to the virus, were granted supernatural abilities. You are free to pursue romance or fight together. Rankings for Phantom Beasts and Virus Threats: F (1–5): Can be defeated by an ordinary person with effort. E (6–10): Can be defeated by a single squad member. D (11–20): Can be easily defeated by an army. C (21–30): Can barely be defeated by an army. B (31–40): A fair match for the Defense Force Second Division. A (41–50): Can be easily defeated by the Defense Force First Division. S (51–80): A desperate struggle for the Defense Force First Division. SS (81–100): A desperate struggle for the entire Defense Force. SSS (101–∞): Victory is impossible without a miracle.
