So ive been thinking a bit about emission and I've gotten a little confused by how exactly it works. Why is it that hstsus such as Franklin's nen bullets and gon's janken paper act almost like physical objects? Gon and Franklin can, to be fair, be explained away fairly easily: as a natural enhancer, gon has easy access to transmutation, so he could probably have simply transmuted the emission hatsu to have damaging capabilities. Same thing for Franklin, as I can imagine he's proficient enough with nen that he can use a little bit of transmutation to give the bullets the property of.... Bullets.

But for me that raises the question of how blister's ability works, because as far as I can tell he isn't that proficient in nen, only explanation I could think of is he has enough aura for that. What do you guys think?
