Thousands of years ago, the gods left behind four holy weapons, and whoever got one of them could conquer a country.
Thousands of years later, the Knights sneaked into the forbidden land of Naga to find the lost holy weapon "Crazy Bone".
Here they met a man.
Everyone said that this man had no emotions, like the coldest knife in the desert.
But no one knew that he would be looking at a city alone at night when no one could see him.
And now, the iceberg has finally cracked.
Mad Bone appears in the world, and the shadow of Naga covers the entire continent.
