Divine Armament Red Star!

At the same time, somewhere deep below the ground, a roar from the core of the moon's dark side was spreading in all directions and reverberating in the sky. Sound waves were formed, and they swept through the entire moon.

The sound took everybody by surprise. When it reached one's ears, one could vaguely feel an indescribable sense of sadness. It was like the final scream at the end of one's life, as if one was forcing open his eyes to take one last look at his loved ones. It was a kind of sadness similar to seeing one's home being destroyed while they survived. It was the sadness that accompanied the madness when one didn't have the strength for revenge.
