When Rocky and the Black Armored Warriors were entangled in a fight, another member of the Imperial Knight Order hidden in the shadows wasn't idle either. This person had been waiting for the right moment and decisively shot a lethal arrow when the opportunity arose!
However, as if the arrow had been expected all along, it not only failed to kill Westwood, but it even caused Rocky to chase in the direction from which the Arrow Feather had come!
Rocky and his team had indeed been prepared for this arrow. Actually, it would be more accurate to say that they had been waiting for it all along, including their engagement with the Black Armored Warriors, which was all for the sake of drawing out this arrow.
If one thought about it carefully, they would see the problem—for instance, why was Rocky taking the lead when they fought with the Black Armored Warriors?
