Kenjutsu is the use of swords, be it by a shinobi, or by samurai. It can be used in combination with Ninjutsu, Taijutsu, Chakra Flow, and Genjutsu. Chakra can be channeled into the blades for more devastating attacks, such as Sasuke when he uses Chidori True Spear. People that practice and are well know for their kenjutsu are Samurai, native to the Land of Iron, as well as the 7 Swordsman of the Mist. Killer Bee is also a very exceptional user of Kenjustu.
I want to learn Kenjustu because I love swords. Sword fighting has always intrigued me, and I would like to have the ability to adequately use my sword in conjunction with an elemental release. I wan to master Kenjustu and live by the Sword.
