As Hakai is back on level ground his opponent makes a very grave mistake. The man before him takes a step towards him and makes a single handseal, shouting what seemed to be a jutsu name. Hakai is stricken by darkness, but as it were to him, thats all the technique does. The darkness is accompanied by a blinding light, similar to a flash bomb, but this doesn't matter much.
The very moment darkness strikes him, Hakai acts. He immediately surrounds himself in Lightning armor so that all of his synapses and functions are running at a superhuman level. By utilizing the lightning armor to its maximum capacity, the 3rd Raikage runs at his opponent at the exact moment, the exact second, the armor is activated faster than his opponent can even realize what happened. When he runs he is far, far too fast for his opponent to even dream of tracking, seeing, or reacting to him. The payoff of this running is Hakai taking out a kunai as he runs, infusing it with lightning chakra, and ramming it into Kakuzu's throat. This of course, completely severs his head and knocks it 5 meters behind the body, which also is knocked about 3 meters in front of Hakai due to the massive impact. Hakai never stops moving the entire time, only stopping once impact is made. Hakai is able to do this because he simply runs into the last place he saw his opponent, he doesn't need his sight to do that.

Hakai finishes off by making a single handseal and causing a large black panther to emanate from his body and strike the area where he hears the body land. When the panther hits the body it will envelop it completely and it should sever any attempt to reconnect the body to the head, as well as completely destroying the body.
