A type of Magic which revolves around the use and the manipulation of the black bands circling all of the users' fingers. These can produce extendable, flat cables, which can greatly be extended in length, and which can be manipulated at their whim. This comes in useful both in battle, where the produced cables can be used to strike with enough strength to shatter rock, and outside of it, enabling the user to cling on various things from the surrounding environment to reach otherwise unreachable heights, to let himself down slowly from the very same heights, and to move around freely. Rayule can no longer use this magic as Hidari has taken his bands during his imprisonment.
- The Magic is unnamed in the manga, but in the anime it was named after a Urumi weapon, which possesses several flexible blades, greatly similar to the cables produced by this Magic.
