Yes i did , and those secret arts of advance taijutsu all revolve around the gentle fist , which requires chakra manipulation which is restricted here , understand? All Neji did to hinata was read her body language by watching her carefully with his eyes then used his own smarts to deduce the meaning behind them. I'm not the one taking away chakra manipulation either. The thread maker made sure to state that doujutsu are allowed and chakra manipulation isn't.
You’re being incoherent. Those secret arts do not all revolve around chakra manipulation otherwise Boruto wouldn’t be use gentle fist as his style of taijutsu.
So clearly you weren’t paying attention at all.
The carefully deducing her body language and all that other crap is nonesense. Go read the fight again. The byukagan can clearly read the intentions and desires of another opponent.
And when Hinata use her byukagan to read Neji’s he was scolded and punished by the elder jonins for his intentions.
That’s why they stopped the match. This is a legitimate ability of the byukagan that was displayed in part 1.
Also, like I said before if you take away chakra manipulations, that means you take away the ability to use doujutsu entirely because every eye activation is a chakra manipulation. Even predicting movements with the sharingan is a chakra manipulation. Look at the zabuza vs Kakazu fight.
