If this guy tried to assassinate Hashirama Senju, he probably would not even get the chance to approach him. An immortal body? A barrage of Wood Style Ninjutsu would pin him down and drain away all his Chakra. Let's see whether he could still survive then. And even if he did not die, there was still sealing. One sealing technique, and Hidan could look forward to spending the rest of his life trapped inside it.
"Send word to all the other major ninja villages. Tell them that the Five-Tails Jinchuriki has already fallen victim to Akatsuki. Also tell them that I, Ōnoki, represent Iwagakure in agreeing to a Five Kage Summit to jointly discuss a way to deal with Akatsuki."
Half an hour later, Ōnoki arrived at the scene with a face as black as charcoal. But aside from calling off the pursuit and sending out the news, what else could he do?
The Fool's Reputation Was Absolutely Deserved!
If he could, Ōnoki, his old face dark at that very moment, would have loved nothing more than to fight Akatsuki to the death.
Unfortunately, he did not even know where Akatsuki was. Wanting to fight them to the death was an extravagance in itself.
The Five-Tails Jinchuriki had been abducted by Akatsuki just like that. It was the same as slapping Ōnoki across the face—and not lightly, either.
Roshi was one thing. He had already left Iwagakure and vanished without a trace. Even if Ōnoki wanted to protect him, he lacked the means. But what about Han, the Five-Tails Jinchuriki?
They had clearly warned you, yet you had stood there like an idiot and somehow let the Jinchuriki secretly leave the village, only for him to run into an Akatsuki member by bad luck, fight them, and get taken away?
