Kokujin's Daisho

The Kokujin's Daisho was made by Kokujin to mirror that of Togashi's Daisho.

Anvil of Despair
The daisho was forged in 1159 on the Anvil of Despair with the soul of Tamori Chieko, who surprisingly was freed and did not die in the process.

Abilities
The daisho was a sinister and corrupting influence and could pass the taint to the wielder and to any who was wounded with it. If the wounded was already tainted, he died after the duel. The daisho increased the duelist ability of its wielder.
