Kekkei'genkai form or One Above God was a very fast, erratic style of lightsaber combat that was not recognized in the Great Holocron or by the Old Jedi Order. The Style, primarily used by Sith or offensive minded Jedi do to its offensive nature, was very deadly, but subtitle simple. The users of Kekkei'genkai generally used Lightdaggers in the stead of Lightsabers, as the style required fast and accurate strikes and blows, and the shortened hilt of a lightdagger allowed that, though this was only a preference.
