Seiken: Ryū no odori

The user increases there already great reflexes by directing Yin energy to their muscles. The user then gets a Battōjutsu stance and waits until the opponent is within attacking range. The user then unsheathes their sword and slams the flat of the blade against the opponents side with such speeds that it can barely be seen. The blow knocks the wind out of the opponent and the user uses that opening to preform a long series of slashes and stabs with their sword. With such skill it looks like a dance, the user moves their sword so fast that it leaves afterimages, and with such strength that each attack can easily break concrete.
