Introduction from the first draft in 2007:
...This is a savage world, an age of hunting. Here, a hunter's moment of carelessness can turn them into prey. The beasts they face aren't ordinary animals like tigers and lions, but wyverns that once dominated countless worlds. They're not highly intelligent dragons, just powerful beasts, I suppose... And the hunters have no high-tech weapons or powerful magic to attack with. All they have are the swords in their hands, quick reflexes, and the resolve to die...
Mai Xing's comment:
...That's what it says, but in reality, we have charge blades (JoJo face) and switch axes (Kenshiro face). I guess we do have high-tech weapons... And there's the gunlance with infinite ammo (laughs).
