Pearl immediately ran behind the lines of these sins.
*CRACKLE*
At this moment, the grey clouds started roaring with black-colored lightning. Sam could see his friends' faces showing some expression. It seems like they are struggling in the sky. The sins kept on being manifested and for some reason, Pearl's forces weren't being attacked by them.
They all turned to Sam and they all moved forward slowly as if they were trying to understand what Sam was.
The sin usually is naturally programmed to attack the person who manifested it. However, these sins are set free because of the overlapping domains. They still have that urge to attack, but they lost their target.
That is why they are trying to process the limited mental power they were granted by this place.
