History
It was all or nothing.

The hunters had come upon their ultimate challenge. Early in Warring States, Tailed Beasts were fought in attempts to be captured and used, either for nations, individuals or clans. The beast on the list today? Kurama.

A group of prideful hunters had gotten to the point where they believed themselves to be the strongest, and best hunters there were. In order to prove so, they tracked down Kurama, which wasn't an easy feat. However, the battle that soon unfolded was even harder. They were no match for the Nine-Tails, and the hunters were easily cut in half in size.

The remaining hunters escaped, with its strongest creating a diversion to keep the fox at bay. About three fourths escaped the range of a Tailed Beast Ball, which killed the hunter's strongest. The ones that had escaped didn't get away empty handed though. Some suffered a mutation, from the ravaging tailed beast chakra in the area.
