Theorems
"I can't believe they sent us to this stupid school anyway." Killua grumbled, kicking nearby rocks into windows with his shoes. "At least they let us opt out of taijutsu."
"I think it'll be fun. We'll get to learn all about this world's history and about whatever they are calling this jutsu." Killua stopped as Gon continued to move ahead. "Killua?"
"About that, Gon," Killua bit his lip, "I don't think we'll be able to use their abilities the way they do short of becoming a jinchuuriki." Over the weekend, he had taken time to memorize the basics and read up on their history. Naturally, his interest was piqued when he saw the word "Jinchuuriki" or in more literal terms, "Power of Human Sacrifice."
"Why not?"
"You probably won't understand, so I'll put it in simple terms. Nen doesn't mix well with chakra. Humans can only have one inner source of power. If we try to stick the two together, they clash and cancel the weaker energy out. In other words, it won't work."
"Now that I think about it, the air does feel weird. People don't seem to have auras either, and they can't seem to sense ours."
Killua held up two fingers. "This brings me to my second point. Nen and chakra are two sides of the same coin; however, nen is built more for defense. I ran several tests, and I think we can mix our nen with the energy surrounding us to create psuedo jutsu. It won't be the same as the original though."
"Yeah." Gon ran over all the options in his head. "How easy was it to gather the chakra around us?"
Killua smirked and gave a cocky shrug. "I don't see why they don't do it more often. I tested it in various scenarios. There was a hundred percent ratio of success."
"Show me later." Gon grinned as he looked at his watch. "But right now, we are going to be late for class if we don't hurry!"
"I'll race you to classroom."
"Osu!" Gon pumped his fist in excitement. "You're on!"
I will explain in more detail later about this, but I prefer to have a bit more development before then.
