As Nero made his way through the door, his stance would be loose and relaxed. Though not completely unafraid, any sort of unnecessary tension in his muscles would only slow down his reactions. At least- that's what Yuffie taught him back on Hollow Bastion. As the visage of the heartless came into view, that's all Nero could think of was his former home, gripping the hilt of his keyblade tighter as that anger he held inside him began to bubble over. Yet, another vision would soon change his demeanor, as his eyes set on a familiar form. "Leon!" In a rush of excitement, he began rushing towards one of his heros. Having grown up on the same world as the gunsword-wielding man, Nero had idolized Leon for his strength and his resolve to continue fighting. How they both came to be upon this world would merely be a question in the back of Nero's mind, more concerned now on just getting to the man. It was then he noticed the bigger heartless, unsure of the name- though taking not it was well armored and seemed to be an amalgamation of different pieces all separate and hovering about a central form. Though Leon had ordered him to fall back, Nero could just leave him alone, "I'll take out one of the arms!" Taking a brief moment to turn his head to the others, "If you can, take out the ranged ones. The less there are, the less we have to worry about." With his attention turned back to the heartless, Nero would rush of, leaping into the air as his blade struck out at the same arm that Leon had parried not a moment before.
