What happened to Nikon's battle song?

The stalk of Nikon's battle song: BGM music and songs with burning blood. In the works with the theme of blood, the fighting music is mostly burning, so it is called the battle song. However, the battle song mentioned in the battle song is not limited to the fighting theme, as long as it is burning BGM. Warfare songs are often sounded before the battle is about to start (or the plot is about to enter a climax), and the atmosphere will soon become excited and can also mobilize the emotions of the audience.
