Luffy, for at least a moment, looked dumbfounded as he stared back at Ivan. He had actually assumed Ivan had only been in Sin's range by accident, a bystander suddenly caught in the crossfire. It hadn't occurred to him that Ivan was actually here to fight! Once he realized this, Luffy began to smile, a very bright and strangely energized smile that almost seemed inhumanly wide. "Yosh, I see!" he replied, nodding his head firmly.

Sin, from behind, had let loose another attack. From the corner of his eye, Luffy had seen it coming, and immediately turned to face it head-on. He raised up a single fist and clentched it so tightly, it gave off an audible sound almost like leather tightening.

"Okay then!" he yelled out, then oddly began to dig his heels into the cracked rubble beneath him. "Show me what you can do, and we'll move in together!"

As the lightning bore down upon him, Luffy flashed a devilish smile, his eyes wide with excitement, then took a swing with his balled-up fist just as the crackling energy was inches away from striking. His hand poured down the center of the blast, suddenly releasing a tremendous burst that sent a concussive wave emanating outward; an acric smoke billowed out, clouding the scene completely in perfect black.

Once visibility was regained, though, Luffy was standing perfectly unharmed, with a small, fading wisp of smoke trailing away from his fist.

"LET'S GO!" he shouted, issuing a thunderous war cry, then began to run straight at the source of the chaos once more.
