Museum of Life

Some time ago, gates opened throughout the world and monsters came out. Only those with superpower can protect the Earth. Other species of sub-human suddenly become popular to human society due to their special power to fight monsters after a long history of being hunted and prosecuted by the most technologically advanced human.

Those who travel through those gates will meet the dungeon. One can only close those gates of dungeons through destroying the heart of the dungeon, a dark stone in the deepest part of the dungeon. Those who try to close dungeons and fight monsters are called hunters.
