Human, Kind of Evil

Millions of years ago, it came as if it appeared out of thin air. Their favorite food was humans. Hiding and running away were the only things humans could do. Fortunately, the gods did not give up on humans just like that. Today, millions of years later, a self-proclaimed god gives a group of humans the power to fight against them, and leads hundreds of humans to Shiva, the last pure land of mankind. But as long as they are not eradicated, Shiva, the last pure land, will one day be conquered by them, and mankind will once again be on the edge of life and death.
