The instant Hashirama Senju and Tobirama Senju charged over.
Naruto raised his head.
His pupils had turned crimson, the patterns of the Mangekyo Sharingan clearly visible.
Kotoamatsukami.
Both eyes activated at once. Agonizing pain exploded deep within his eye sockets, and blood streamed down from the corners of his eyes.
The Yang Release Chakra in his body had no time to repair damage of this magnitude.
The two men charging at him stopped.
They stood nailed rigidly in place.
"Impossible!"
The shock on Orochimaru's face could not be concealed. "How could my technique have been undone?"
Naruto tugged at the corner of his mouth.
"Ever heard of Kotoamatsukami?"
The official definition from his previous life had been simple—anyone seen by the caster became his puppet.
It was the only genjutsu capable of wresting control away from the caster of Impure World Reincarnation.
Not even Itachi Uchiha's Tsukuyomi could do that.
The ability of Naruto's Mangekyo Sharingan happened to be Kotoamatsukami.
After using it on Sarutobi Clan Asuma before, his ocular power had recovered considerably through the dual nourishment of Asura Chakra and Yang Release Chakra.
But using that still-unrecovered ocular power to erase the wills of Hashirama Senju and Tobirama Senju was impossible.
He needed to weaken the brothers' mental defenses further.
The only thing capable of doing that was the talisman in Orochimaru's hand, the one that could erase the personality of an Impure World Reincarnation body.
And if Naruto wanted the Senju brothers to serve him long-term, the Impure World Reincarnation ritual had to be completed.
The talisman had not yet been inserted into their bodies. At most, they were in a half-baked state—immortal, but unable to regenerate on their own.
More or less like Hidan.
No matter how one looked at it, Naruto had to help Orochimaru
