Full Moon Cut (Engetsu-giri)

"You will die...
...by the time my sword completes the circle."

From the Hagakure Kikigaki:

"It is a principle of the art of war that one should simply lay down his life and strike. If one's opponent also does the same, it is an even match. Defeating one's opponent is then a matter of faith and destiny."

Engetsu-giri is one of my favorite chambara film series. The series follows the travels of Kyoshiro Nemuri, a ronin who lives by his sword and wits.
