Kurapika
Once there was a spider that had twelve legs. The spider was an abomination among all that was considered natural from the inside out. Each leg was like its own monster, and it trampled anything in its way, leaving blood and horror in its wake.
One day, the terrible spider made its way to a village full of a peaceful tribe of people. The innocents were caught in its web before they knew it, and were left as eyeless, or sometimes headless bodies. All for a pair of eyes.
Yet there was one that managed to escape that web. A young boy, on adventures of his own. When he found out about what the spider had done, he rushed back home only to find blood, long burned out fires, and destruction.
It was like the spider had left a poison afterwards because the boy became sick. He was sick for many days and nights before he got angry. The sickness fueled his rage and he vowed to kill the spider until only a memory remained.
Years passed before he managed to find the spider, though it was from a leg that had wandered astray. The leg was still a terrible creature, but he allowed himself to get close to it in order to destroy the remaining ones.
A long time passed before the boy was able to sever one leg. But was terrible, and he feared having to sever the rest because of the poison it left behind. It made him sick again, but he worked through it.
In even less time, the boy severed another through a series of unfortunate mishaps. This leg made him sick as well. Though for different reasons. Their poisons seemed to vary, but once again he kept going.
When the boy managed to get a hold of the head, he couldn't kill it. The head's poison was too strong, and even though he crippled it, it still managed to hurt him more.
As the spider hobbled away, the boy vowed that he world first recover what had been trapped in its web. Then, he would destroy it for good.
