Zsoltgewinn, otherwise called the Demon Sword, is a Busoma in the possession of Takuma Miura.
Origin[]
A long time ago a village was attacked by barbarians. the villagers tried to pray to their gods but they didn't help. So they decided to pray to a demon instead, thus marking Zsoltgewinn's first appearance in the hands of the demon. The demon slayed all the barbarians and the people of the village gave thanks to him. However the villagers had forgotten that Zsoltgewinn was not a God, but a demon, and were all murdered by the blades holder.
