Sacred Katana

The Sacred Katana is a one-of-a-kind weapon that is dropped by Shujitawan after you defeat him. It is an Iron Sword with. It is the 2'nd strongest sword in the game.

Trivia
The Sacred Katana is actually not the weapon Shujitawan uses in battle, that would be the Meiji Longsword. But it is the weapon you obtain when you defeat him because the Sacred Katana is actually Shujitawan himself. As when he is defeated, he transforms into the katana and serves whoever beat him as their new "Master". And will only return to his humanoid self after their Master has perished (just lore, no impact on actual gameplay).

Shay D. attempted to kill Shujitawan in order to become the master of the Sacred Katana and then use it as "the world's fanciest kitchen knife". Shay failed and escaped narrowly with his life but he greatly wounded Shujitawan, which was impressive because Shay was a city slicker with no combat experience while Shujitawan is an immortal warrior.
