The terrifying black impact directly annihilated the falling island fragment, leaving not even a trace of residue.
In terms of efficiency alone, this was far faster than Karin's method of grinding it down bit by bit with wind.
Moreover, it was pollution-free and residue-free. Apart from the 'insignificant' risk of potentially hitting some unknown location in the distance, there was basically nothing to complain about.
That blast came and went quickly, appearing for only a few seconds, dissipating immediately after destroying the island.
Then, a pure white figure appeared over this sea area as if by teleportation. Only after he had been there for a while did the wind pressure and the sound of breaking the sound barrier belatedly arrive.
From this, one could see just how terrifying his movement speed truly was.
In fact, if one disregarded Kizaru, the 'light human', achieving the theoretical 'speed of light' without any constraints, Naruto's speed was probably the fastest in the entire One Piece World right now.
Even Enel, who had flown to the moon, probably couldn't catch up.
"Whew... just in the nick of time. Made it."
Naruto reverted from his Otsutsuki form back to his usual appearance, then quickly flew upward, steadily catching Karin, who was shrinking smaller and smaller in the air.
Perhaps due to overexertion, Karin had now returned to normal human size, but the Garuda transformation effect still persisted… her entire body remained in the beast-man form.
"This really is... looks like I missed quite a bit."
Naruto's eyes calmly observed Karin, watching this unconscious young girl. His gaze seemed to pierce through her physical shell, seeing something more 'essential' inside her.
To be honest, even Naruto hadn't expected Karin to cause such a commotion.
The spectacle he had created over the past twenty-plus years of performing heroic deeds and stirring up trouble on the seas didn't seem much greater than this little girl's.
He mused inwardly that kids really could cause more trouble than him, but his actions didn't slow down at all.
His five fingers spread wide. The [Sea Senjutsu Chakra], created by merging with the Natural Energy of the One Piece World, rapidly condensed at each fingertip.
"Better settle down for now."
Even though Momoshiki was now playing turtle in Karin's mental space, Naruto hadn't forgotten about him.
He had been drawn here by Momoshiki's aura.
To be honest, if Momoshiki hadn't partially broken free after swallowing Imu's power, Naruto wouldn't have been able to pinpoint his location so quickly in this vast, boundless sea.
After all, the Otsutsuki aura was far too unique. There were only two such signatures on the entire planet.
Moreover, as a race that frequently traversed the cosmos, the Otsutsuki seemed to possess some kind of detection mechanism for their own kind. At the very least, Naruto sensed it the moment Momoshiki broke free.
Conversely, Momoshiki had probably also sensed Naruto's approach.
Otherwise, he wouldn't have suddenly lost his nerve.
Five fingers pressed against the back of Karin's hand. Starting from the fingertips, faint blue lines rapidly spread across her entire arm.
These lines crisscrossed and wound tortuously, somewhat resembling the shape of waves.
This was another thing to thank Momoshiki for. If not for him, Karin's body wouldn't have recovered to the beast-man state so quickly. In that case, Naruto would now be pressing on the base of Karin's wings.
Spicy chicken wing...
Salt-baked chicken wing...
For some reason, the moment he thought of the wing base, Naruto's train of thought instinctively veered off in some strange direction.
Just then, a dazzling golden light burst forth from Karin's body, beginning to resist the sealing technique Naruto was applying.
"Hmm?"
Although it hadn't been named yet, this sealing technique was something Naruto had forcibly created by combining Adamantine Sealing Chains, the Five Elements Seal, the Eight Trigrams Seal, and the Four Symbols Seal, utilizing the Otsutsuki Clan's innate ability to control Chakra.
The Chakra it used was also unique Senjutsu Chakra, which was exceptionally effective even against the Otsutsuki.
But this golden light seemed unrelated to the Chakra System, so Naruto's suppression of it wasn't particularly strong.
It was like some kind of special mechanism, constantly maintaining the host's body in a fixed state.
Seeing this, Naruto's eyes widened, his pupils instantly replaced by white.
That was the Otsutsuki Clan's Byakugan, capable of x-ray vision and detecting energy flow.
In Naruto's observation, countless golden threads spread from Karin's heart throughout her entire body.
It was this power that had protected Karin from Momoshiki's influence. However, due to its interference, the reinforcement seal Naruto was applying to Momoshiki/Karin progressed slowly.
Looking at the golden energy bound to her heart, Naruto pondered for a few seconds, then made a decision.
Clearly, although this power was essentially protecting Karin, its presence was now affecting her state.
"I'll temporarily extract it."
As for how to separate the golden energy entangled around her heart and veins, Naruto wasn't particularly worried.
Just as Karin had initially thought, Naruto was a user of the Baku Baku no Mi.
"Perfect chance to try this move—"
The pupils in Naruto's eyes turned from white to yellow, then a black outline appeared.
That was the second Dojutsu, [Kokugan].
The Kokugan Dojutsu Naruto mastered… or according to the Otsutsuki clan's internal classification, should be called a [Divine Technique], its name was [Onogoro].
This was a Divine Technique born from combining the power of the Baku Baku no Mi to devour everything, powerful enough to destroy the world.
Its essence was to transform oneself into one of the most dangerous celestial bodies in the universe, a 'black hole', capturing and absorbing all energy.
The moment the Divine Technique was activated, all surrounding energy began to flow towards Naruto.
His body surface also turned pitch black because light could no longer escape.
The energy transformed from Pure Gold residing in Karin's heart had no power to resist when faced with the innate suppression of Onogoro.
Ultimately, it was merely an inanimate object, not truly possessing self-awareness.
With one hand supporting Karin, Naruto absorbed the Pure Gold energy from her body, while his other hand continued the previous sealing.
—Regarding the handling of Momoshiki, he still planned to wait until Karin awoke and hear her thoughts before deciding.
Within the sealing space, Momoshiki looked on despairingly as the surrounding 'sky' was rapidly covered with layer upon layer of deep blue energy.
The thickness of that energy alone, even without testing, clearly conveyed one word.
Despair.
'Damn it! That contemptible lowly monkey.'
'Clearly, this power belonged to the Otsutsuki Clan, so how could he apply it so effortlessly?'
'It was definitely that Kaguya's fault!'
'If she hadn't separated from his body, allowing him to fully take over this Otsutsuki power, this blonde monkey definitely wouldn't have become this strong!'
Apart from resentfully cursing Kaguya and Naruto in his mind, Momoshiki was truly helpless.
This wasn't his fault.
Judging by the energy intensity Naruto was currently displaying, he had already surpassed Momoshiki and Kaguya at their peaks, and was even at a top-tier level within the main Otsutsuki Clan itself.
'Just how strong did this damn lowly creature intend to become? Was it possible he could actually become the legendary [Otsutsuki God]?'
This question of Momoshiki's was destined to remain unanswered.
In fact, not even Naruto himself knew exactly what he would become.
