Tucking and rolling when Jonah's reports rang out, Shin found himself behind another post, though prostrated for a moment. He slapped the ground with his right and shoved himself back to his feet, the man was a deadly threat with his guns. 

That disgusting lipless smile of his would have shown if not for his mask, imagining himself with that weapon in his hand was a delicious thought. In that moment the arm viciously whipped upwards and began firing off round after round towards the wall between him and the old gun. A total of seven rounds were fired into that wall, he had very little control over the rate of fire. It was again acting of its own accord, he was not happy about it but at least it was doing its job. Shin moved towards the building and continued firing, seven more shots. 

He silenced his firearm for a moment and made a tactical decision. So far, he had not revealed whether or not he needed to reload. Probably easy to assume by this point that he did not need to, but gambling on the slim chance that maybe the old gunman fell for it. Shin reached the edge of the building that Jonah had entered. Hopefully he hadn't blown enough holes to be visible, but it didn't matter. 

Once he reached the post he grasped it and hoisted himself up onto the rooftop. He caught himself with his hand and let his weight down softly. Preventing himself from making too much of a noise as he made his tactical advance. He would stay atop the overhang for a moment and then silently creep across the top of the building. If Jonah came back out the same way he had ran, Shin would open fire from above. If not, he would advance across the top of the building.
