When leaving the Rain Village, Hanzo didn't tell anyone and departed in secret alone.
Hanzo thought a lot in one day.
Shimura Danzo's plan is indeed beneficial for the Rain Village, as it could help the village eliminate the potential threat of the Ninja Sect early on.
However, it's only beneficial for the Rain Village. The death of a ninja like Sosuke is a loss to the entire ninja force of the Land of Rain.
Because not only is Sosuke himself strong, but he can also lead others to become stronger together.
Moreover, Sosuke holds a considerable amount of respect in the Rain Village; if the village unilaterally tears up the agreement and attacks Sosuke, it could very well lead some Rain Ninjas to be disappointed with the village.
Swoosh!!
Hanzo erupted with chakra, utilizing his masterful Water Instant Body Jutsu to the utmost, advancing rapidly towards Six Paths City, as if something terrible would happen if he were to slow down even a bit.
For a ninja, the distance between the Rain Village and Six Paths City isn't far; one is located in the central part of the Land of Rain, the other in the east.
With Hanzo traveling at full speed, he quickly saw the town he had visited not long ago.
Recalling the memory from his last visit, Hanzo quickly bypassed the guards of the Ninja Sect and entered their premises.
"At this time, would he still be in the office?" Hanzo contemplated how he could directly find Sosuke.
He only knew where Sosuke would be working, but not where Sosuke usually resided.
"Senior Hattori, what brings you to the Ninja Sect to admire the moon at this hour?"
Just as Hanzo was wondering where Sosuke might be, a familiar voice reached his ears.
Following the direction of the voice, Hanzo saw Sosuke standing on the ground, smiling at him.
Instinctively, Hanzo glanced around, and after confirming there was no one else, he quickly jumped down from the rooftop, his face darkening as he said:
"I am not Hattori."
"In this outfit, aren't you Hattori?" Mokgetsu said with a smile as he led Hanzo into his office.
At this moment, Hanzo was disguised again, not using his original appearance.
Hanzo recalled that embarrassing past, and silently followed Sosuke into the office without speaking.
"He definitely has the ability to see through my disguise," Hanzo thought to himself, feeling somewhat relieved.
During the second lecture, Hanzo had the idea of disguising himself once more to test whether Sosuke's ability to see through his identity the first time was coincidental or due to his skill.
However, Hanzo never acted on it because he believed Sosuke to be unfathomable, and it was better not to test him lightly.
"Take a seat. You've suddenly come to see me; is there something you need?" Mokgetsu asked, sitting on a wooden chair in his office.
Upon discovering Hanzo, Mokgetsu immediately speculated about Hanzo's purpose.
Coming alone to the Ninja Sect at night must mean there's something important.
With the Root Ninja previously detected at Six Paths City, Mokgetsu first guessed that it might be related to Shimura Danzo.
"Konoha plans to target the Ninja Sect." Hanzo came straight to the point without delay.
"Konoha? Where did you get this information?" Mokgetsu inquired with a slightly surprised expression.
Upon hearing it was Konoha, Mokgetsu could almost be sure that it was Shimura Danzo causing trouble.
Because Sarutobi Hiruzen advocated for taking a breather after the major victory over Hidden Rock. Konoha would only retaliate if provoked, and wouldn't take action proactively.
"The Hokage Assistant, Shimura Danzo of Konoha."
The answer was as Mokgetsu expected.
"That's quite interesting; Konoha actually revealed their plan to you."
"Because they want me to help them, to assist them in killing you."
Mokgetsu couldn't help but sigh inwardly. Shimura Danzo truly isn't afraid of repeating old tactics. He'd already played a similar scheme before, and now he's at it again.
"So, are you planning to help the Ninja Sect now?" Mokgetsu looked at Hanzo.
Mokgetsu couldn't completely understand Hanzo's current intentions.
Because Hanzo is currently in a very complex period.
In his prime, Hanzo was a demigod of the ninja world, revered by countless ninjas.
Even the Second Ninja World War couldn't bring an end to Hanzo's glory, because despite the Rain Village's defeat, Hanzo himself hadn't been bested by any ninja on the battlefield.
But now Hanzo is aging, and his remaining glory has become a stepping stone for Mokgetsu's alias to become famous in the ninja world.
During his glorious days, Hanzo had the courage to challenge the Five Great Ninja Villages and the grace to let geniuses from opposing forces walk free.
Yet in his aging days, the once glorified Hanzo could, for the sake of power, harbor murderous intentions against domestic harmless ninja forces, fearing enemy retaliation so much that he requires 24-hour protection from his guards.
So even though Hanzo came at night to inform Mokgetsu of Shimura Danzo's actions, Mokgetsu couldn't be completely certain that Hanzo would side with him.
Mokgetsu isn't someone who believes everything he's told. This could be part of Shimura Danzo's scheme or part of someone else's conspiracy.
"No, I won't help. I'll agree to Konoha and try my best to kill you," Hanzo replied with certainty.
"Hm?" Hanzo's response was somewhat unexpected for Mokgetsu.
Running to the Ninja Sect's stronghold to inform him of Shimura Danzo's plot, and then claiming he would assist Shimura Danzo in killing him.
If Mokgetsu hadn't confirmed through Identification Jutsu that this was indeed the real Hanzo, he might have thought someone had disguised themselves as Hanzo to draw animosity towards the real Hanzo.
"Indeed, Shimura Danzo harbors ill intentions, but he's somewhat correct; the Ninja Sect and the Rain Village are destined to clash," Hanzo explained in a deep voice.
"Rather than letting a major battle between the Ninja Sect and the Rain Village break out in the future, causing war to spread throughout the Land of Rain, it's better to bring it to a resolution now."
"We'll let only a few trusted individuals act. From then on, it's a matter of skill; you die, you lose, and all ninja from the Ninja Sect will join the Rain Village."
