In the dead silence, a horrifying voice came.
Under the Sacred City, something was swallowing and drinking with great joviality!
The monster that had been imprisoned under the Sacred City could finally have a great meal after having hungered for several hundred years.
When people heard that sound, their expressions became extremely pale. They finally remembered that just under the Sacred City... was something they had totally forgotten.
It was the horrible monster that caused a huge disaster even before the Remote Time, and burned half of the Sacred City to ashes. It was the real "natural enemy" of people in the Physical World.
It was imprisoned hundreds of years ago, so nearly everyone had forgotten it or thought that it was already dead. But it was still alive after so many years of being imprisoned.
It woke up from a long sleep and devoured the blood greedily, like eating manna.
