Wind Release: Seven Hills of Rome

A devastatingly powerful technique used to attack large groups, it's lethality is only matched by it's versatility. The user calls down a series of funneling whirlwinds from the skies, which will proceed to carve their way to the desired target, much like a tornado. It is powerful enough to tear through solid stone, launching several pieces of sharp debris at a foe in the process. The technique may also be used to burrow through the ground in a manner which would cause it to collapse underneath the opponent's feet.
