Urumi is a type of curling blade.
Urumi is a blade that looks normal when sheathed, but is actually longer that the sheath itself. It was the chosen weapon of Pesylian, and the one that give him his nickname of Void Executioner.
Rather than a sword, an urumi resembles a long and thin metallic whip.
This long sword is made of a soft metal which bends and flails easily, enabling its wielder to attack his/her opponent in multiple areas thanks to its flexible whip-like blade. Nevertheless, it's incredible difficult to use and control.
- The urumi is an actual sword that originated from India.
