Here is another weapon and this one belongs to Twilight or The Twisted of Souls.

There is a dark tale behind this weapon. Many moons ago in feudal age Japan there was a blacksmith that lived in a small town called Higarashi. Now many thought for this town to be normal as most of the other towns. Well they were wrong. There was a rumor about the village that when ever travelers go through the village they suddenly disappear without a trace and the last one to see them was the Blacksmith. In fact there was on traveler that almost made it out of the village, but never did. What the blacksmith was doing is that with each traveler that passed through the village, he would take them or more like fool them into coming into his home. From there he did unspeakable things to them. In fact with this sword, the mad blacksmith had forged the sword from the human blood and bones of both humans and a few demons. The souls of the dead demons and humans where thus sealed into the sword, which had in turned suck the life from the blacksmith.
