A Monster World Without Useful Hunters

This is a story about blasting a Great Jagras with a greatsword, fighting a Rathalos with an RPG, and bombing a Mountain-That-Burns-the-Sky Dragon with a cloud bomb.

Naturally, it also features railguns trading fire with Blue-Eyes White Dragon, and human hunters battling Red-Eyes Black Dragon.

See what happens when monsters invade the world and collide with it. And, well, watch how useless hunters struggle to survive in the Empire of Rathalos (or so they say).
