Awakened in an Unfamiliar Era

Facing destruction, humanity had sealed their strongest fighter in a chamber where they could grow stronger, while the rest of their kind fought to buy their champion time. However, after you are awaken 2000 years later surrounded by humanity's oldest enemies, will you strive for coexistence after humanity's extinction, or engulf the new world in flames with your own hands?
