The only things that comes to mind is to drain 1 of chakra or close those points in the human body that Neji and his clan can do.
Samurai use such a technique.
Don't really get the point of this topic though? What are we supposed to discuss?
That tech stops people from forming handseals. He speaks about the ability to "sillence" the enemy so no jutsu can be activated.
He also speaks about jutsu as a wide term so that. would mean anything aside from normal crep? Genjutsu, 8 gates and so on would be out. Funny thing is taijutsu also falls into this category.
I am sure people like Itachi who can activate (do handseals) faster then a sharingan can keep up are probably immune lol. Also jutsus that don't need handseals are going to activate. Genjutsu would also work as long as it does not need handseals.
I also don't know the purpose of this topic, perhaps he can elaborate. If i would be to take i gues perhaps he whants the manga to go back to more taijutsu based battles like in part 1, something that i would not mind. Biju vs Biju and mountain busting vs mountain busting get's old fast.
And I think that kind of jutsu do really exist in this manga. But the question is, who's that ninja capable enough to create that amazing sealing jutsu? Hashirama/mito or minato/kushina?
My bet is minato.
It seems like in order to stop someone from performing a jutsu, you need to find a way to:
1. Physically incapacitate them
2. Find a way to alter their chakra
A jutsu that does one of the two above (probably preferably number two) would most likely work. Having a jutsu that just somehow automatically cancels another jutsu doesn't seem to fit in the mechanics of the Naruto-verse. You'd need to do something to the person trying to perform the jutsu. There are definitely jutsu that exist that affect the user in such a way. For example, Jyuuken, genjutsu. Sealing techniques would probably work.
I think Pein was the best at this with those pipes things. JMan was really messed up after geting impaled.
Jutsu cancellation no jutsu would be a horrible idea, At the very least, there should be heavy restriction or price to pay, otherwise ninjas can learn and spam this and be all .
Noooo, they should focus more on basic ninja techniques like kawarimi, henge, and bunshin no jutsu.
