God Eater, Hunting Leviathan at the Beginning

When the apocalypse comes, I coexist with the virus and transform into a walking natural disaster, devouring everything! The end is coming and civilization has fallen. In despair, I coexisted with the deadly virus and became a walking disaster capable of devouring everything. Zombies are my food, alien species are my ladder, and I evolve crazily in endless devouring. When the remaining humans saw me as the ultimate threat more terrifying than zombies, they finally understood that I was the doomsday itself. This novel and its characters are purely fictitious.
