After the necessary hand seals, the Sonic Blades light up with 10,000 or 7,500 volts of electricity through his arms and hand. The user then puts his Sonic Blades in a parallel movement, rushes in great speed, breaks through the sound barrier, and slashes through the opponent. The opponent will then start to faint, but suddenly, a huge volt of natural lightning comes out of nowhere and strikes the opponent, striking the opponent directly. This move is only used once per day.
