Killing Field! is the battle theme for the feudal Japan chapter, "Secret Orders". It plays during a majority of the battles you will fight in this chapter, except for the chapter boss and the optional boss Majin Ryunosuke.
The song is also briefly played during the Watanabe scene for this chapter, as well as a small scene where an old man that you can find spins you around (after killing the woman he was spinning in the first place).
This song is track 5 on the official soundtrack.
