Piece
Sitting in front of the pawn was a board. Roughly scribbled onto several pieces of paper were figures that looked vaguely angelic or demonic, and they were all pinned to the board by various sharp implements. Strings of various sorts were used to tie the whole ensembled together as the shadow creature stared ponderously at all factors. It didn't make much sense at all, especially given how poorly it was drawn, but the images seemed to generally encapsulate the situation. There was a weakling, an angel, and a few demons with SINNER clawed into the center. For a while Piece was content just looking over it, occasionally glancing at the fight through a window, but suddenly it stilled. "It's not my fault, my master! I gave them my advice, but they were too incompetent to hear even that. How could I know that they would take so long? Then there's that other pigeon flapping around with zero substance. She's worthless, completely worthless! I don't even understand why she's still here!"
The creature flickered back and forth in agitation, the dying light allowing it to move about far quicker than normal. But then it vanished. For an extended time Piece simply didn't appear anywhere. Then with a sudden jolt and a sound like static it was spat out of darkness. Of course, it wasn't like the creature could actually feel pain. It wasn't capable of such sensations. Instead the light from its face flickered erratically without any sign of control. It scrambled to bow to absolutely nothing, its voice a discordant chorus of fractured voices.
"Of course not, my merciful master. I would never wish to disappoint you, not even out of negligence! I will surely cure you of that sickness!" For the first time the pawn moved without laughter, or humor, or even the slightest bit of mockery. It grabbed the gun and shoved the dark mana batteries in, every last one of them, far too many for the weapon to hope to fire without a catastrophic accident. It pulled the trigger and vanished. Then it appeared again in the shadows cast by the cocoon's newest shape, the gun crackling with furious power and shaking at the force contained within. It was on the verge of breaking. So of course Piece hefted, already in motion as it emerged from the shade, throwing the weapon right in the path of the Rider's descending blade.
