The ninja collided with Danny in midair, sent them both rocketing back into the wall of the building he'd just leaped from. That was really bad timing. Danny hit first, the guy slammed against his chest. Brick crumbled behind his back before he and his surprise assailant both crumbled in a heap on some trashcans in the alley below. With the wind knocked out of him, it took Danny longer than he liked to get his breath back and by then the other guy was on him, apparently less harmed since Danny had absorbed most of the impact with the wall.
Danny got an arm up in time to cover his face, bringing his other around to land a punch on the side of the ninja's head, but not before he got a nasty slice to his forearm. Rolling back and away he got to his feet and drove a knee into the man's face when he raised it. It wasn't a particularly fair move, but then this wasn't meant to be a particularly fair fight. When he was sure the assassin was down, he lurched to the fire escape of the building the photographer (who clearly was a lot more than just that) was on and climbed up.
"What the fuck?" he echoed her sentiment, hauling himself over the edge of the roof (but keeping well away from her), as he watched more shadows converging on them from other rooftops. "Watch where you're throwing people," he snapped, but otherwise Danny didn't seem particularly surprised or perturbed by the fact that she'd just thrown a full grown man at him hard enough for the pair of them to leave a crack in the brick face of the next building. His adrenaline was helping him work through the pain in his back for the moment, but he was sure he'd be sore as hell in the morning. Danny took the few moments of reprieve to shake out his shoulder and then held glowing fingertips up to the gash on his arm to heal it. "Incoming," he muttered, and took up a defensive stance as a half dozen figures ran at them from all sides.
