Why call him Uchiha Aomi?
Faced with this question, Black Zetsu certainly couldn't say, "That's just your name, what's wrong with me calling it?"...
Regarding the issue of the terms brother and younger brother.
Aomi is indeed very fond of calling it "foolish younger brother"...
Black Zetsu outwardly resents it, yet upon hearing it, there's always a slight stir within, after all, in terms of bloodlines, it counts as family...
Only Kaguya and Aomi, that is.
As for Otsutsuki Hamura and Hagoromo, these pure rebels, Black Zetsu had long unilaterally expelled them from the family registry...
Although Black Zetsu also considers Aomi a rebel.
But among rebels, there is quite a difference...
Aomi indeed disregards Kaguya completely, from the very start looking down on Kaguya's power and combat skills, fundamentally never treating this Ancestor of Chakra like Black Zetsu did, as the core of a plan...
In Black Zetsu's view, compared to Kaguya, Aomi truly embodies the Otsutsuki character and demeanor.
But even so, Aomi still retains a bottom line… For instance, Aomi never laid a hand on Black Zetsu.
Black Zetsu actually knows very well, those little tricks it's been up to with Uchiha Obito and Uchiha Madara behind Aomi's back, its brother actually knows them all.
With Aomi's abilities, it could have dealt with Black Zetsu long ago, even killing it would be reasonable...
Yet Aomi never did so, instead, always allowing Black Zetsu to mess around.
Over time, after repeated efforts to resist Black Zetsu failed and it was let go by Aomi, it started to struggle to maintain its facade.
Black Zetsu feels like an unruly younger brother, just relying on his brother's generosity to do childish things, like an ignorant, willful child...
In the quiet of night, when calming down to reflect, Black Zetsu sometimes even thinks Aomi's line of thought isn't entirely wrong...
In some ways, even very correct.
Power should be held by those with intellect, only then can it yield the greatest results, effectively facing the Otsutsuki Clan...
If left in Kaguya's hands, just how much of its full potential could truly be achieved?
If not for Aomi, Black Zetsu thinks it could also serve as a qualified backstage manipulator to resurrect Kaguya.
However, the best outcome would likely be Kaguya resurrected as Ten-Tails Jinchuriki, with Black Zetsu having to find ways to teach Kaguya to fight, to get past the Six Paths Sage and Otsutsuki Hamura...
Not to mention facing Urashiki, Momoshiki, and Isshiki, these three mighty Otsutsuki.
As a behind-the-scenes manipulator of the Ninja World, Black Zetsu's scope is actually limited to mere mortals of the Ninja World, anything reaching Six Paths Level leaves it completely in the dark...
If it followed its own script.
Black Zetsu believes there's a high probability it and the resurrected Kaguya would be intercepted by these celestial Otsutsuki during battle with the Six Paths Sage and Hamura, rendering millennia of planning in vain.
In contrast, while Aomi's attitude and actions towards Kaguya seem excessive...
The results, nevertheless, are unexpectedly favorable!
The three celestial Otsutsuki aren't even a match before Aomi, vanquished with simple punches and kicks, whereas Zetsu's long-feared Six Paths Sage and Hamura don't dare appear before Aomi...
Only sneaking into the Ninja World after Aomi's disappearance.
Judging purely by results, Black Zetsu has long submitted to Aomi...
Its brother had long seen through Kaguya's frailties, never indulged in fantasies about her, instead firmly gripping fate in his own hands.
Aomi, is the true victor...
Moreover, a victor in grand style!
These are things Black Zetsu had subconsciously understood long ago, only refusing to face the conclusion due to the silent cost of millennia of efforts...
Standing before Aomi.
Thoughts uncontrollably surged through its mind like electric currents!
Thus when realizing—"Aomi has no faults," this conclusion exploded in Black Zetsu's mind, the usually eloquent Black Zetsu could only stand there half-open mouthed, speechless...
Aomi looked at the silly, frozen Black Zetsu, slightly shook his head, a hint of disappointment in his eyes, before slowly turning away.
As if about to leave...
At this moment.
Afraid of Aomi disappearing again, Black Zetsu managed to squeeze out a sentence: "Brother, I-I was wrong, I have something to ask of you!"
"Please help me!"
Aomi sighed, turned back, gazing into Black Zetsu's eyes full of struggle and dread, slowly said, "Speak, what do you want from me?"
"It's about Obito's matter! Regarding Obito!" Black Zetsu murmured.
"What happened to Obito? I don't know about his matters, what do you want me to do?" Aomi spread his hands, seemingly puzzled, looking at Black Zetsu.
Black Zetsu took a deep breath!
How can Aomi not know about Uchiha Obito's matters?
On the battlefield, Black Zetsu clearly saw Aomi channeling ocular power into Uchiha Obito's body...
And from Black Zetsu's understanding of Aomi, Aomi absolutely wouldn't allow Isshiki to possess Obito easily.
In Black Zetsu's view, though Aomi is heartless and cold, towards those around him, he maintains a mysterious bottom line, rigorously tormenting them...
