Bakuryūga

Bakuryūga (爆竜牙, Explosive Dragon Fang): A katana that Xin carries within his haori. It has a grey sheath with a red ribbon tied to the top of it. The hilt is wrapped in white cloth, with the crossguard possessing a diamond-like shape. Unique in creation as it is said to have been forged from the souls of ten thousand slain men, Bakuryūga contains the ability to fire explosive acidic bursts of energy capable of corroding through any object. Even the strongest of men have fallen victim to its blade and ability. Those that are significantly strong risk having their body disintegrated by Bakuryūga's corrossive energy bursts. The sword itself is capable of disintegrating anything cut by it's blade.
