meh, the only thing original about that is the number of swords combined, it sounds cool but it is in no way functional in a realistic basis. To make the sword, while all of them are combined, useable in a real fight (meaning not so heavy that the fighter could wield it), the metel would have to be either so light it would dent or chip easily, and eventually break in a real fight. To make the metal useable in the sense it could withstand blows, would mean the sword, when combined, would be impossible to weild effectively due to it's heaviness. Also SIX swords? Clouds either mastered the martial art of swordsmanship juggling, or he's pulled a Dr Octopus and had four more arms grafted onto him.

Just another example of Nomura attempting to grandstand again, without involving much real thought. Though I will give him credit for actually thinkng how the six blades would combine.
