Nanashi sighed at Natsu’s question, “Honestly I’m not 100% Sure what I wanted to explain either. But I guess in the most general way of speaking, I wanted you guys to understand your Gunplas more. Pure talent can only bring you so far, it's only when you understand and your machine inside out can you take its ability to the fullest.” He said as he wrote down more into his notebook. “How far a joint can move, how to repair it when damaged, knowing which parts are easier to fix then others and which are essentially for battle. Each Gunpla has their owe qualities and I feel like neither of you know ALL of them.”
