This is a short anime voice clip of Kenshin Himura calling out his Hiten Mitsurugi technique, Ryu Tsui Sen, with the sharp, focused energy of a swordsman mid-attack. It feels swift, dramatic and heroic, like the split second before a duel is decided. It comes from Samurai X, where Kenshin uses the flying-dragon sword style against his opponents.
