This is a world belonging to monsters. They are the masters of this world and rule humans. However...
"Huh? I've traveled through time. It's wrong. It's different from what I thought. Why are humans so weak? Run quickly. The monster is coming. I can't beat it. Someone come and save me."
"Huhu, shouldn't I be the protagonist? It's not like "The Classic of Mountains and Seas"? What's the use of this! I really appreciate it."
