There were once two races who ruled over earth, HUMANS and MONSTERS.
One day WAR broke out between the two races...
After a long battle, the HUMANS were victorious.
Then they sealed the MONSTERS underground with a magic spell...

In the year 201X, a small child scales Mt. Ebott...
It is said who climbs the mountain NEVER returns.
Seeking refuge from the rainy weather, the child enters a cave and discovers an enormous hole.
Moving closer to get a better look... the child falls in.

This is the beginning of our story...
