As soon as the fight began, Nick's arm shot inside of his jacket to pull out a gun. finding bullets for a centuries old death machine was hard work, but Nick found a way. A grunt was let out as he took cover, letting out two shots before looking over.

"So much for a peaceful talk." He let out another grunt, kicking down a table to use as cover. "Nick Stars, detective." He introduced himself quickly, firing two rounds before hiding once more. "We need a way out. Either through them, or through the back. Think they're smart enough to guard both entrances?"
