——

Trait Detected (Aisa): Innate Observation Haki (Apex Gold) (Uncontrollable) (Equippable): Exceptionally powerful Observation Haki, awakened at birth. Extremely high level, vast range.

Uncontrollable: Due to young age and insufficient spiritual strength, cannot control this Haki, only passively 'hear' various voices and presences.

Equippable: Due to arriving with the 400-year promise and forming an alliance with the Shandians, can be equipped using the combined spiritual power/obsession of Kalgara the Great Warrior and the Shandians' 400-year dedication to ring the Golden Bell as a conduit.

——

Rowen's eyes lit up as he read Aisa's Trait description.

An Apex Gold tier Observation Haki!

Currently, among Rowen's Haki types, Conqueror's Haki was the strongest—capable of exerting Apex Gold level combat power due to Haōshoku Coating's domineering force.

Armament Haki was next, at Deep Gold level.

Observation Haki was his weakest, only at Pale Gold.

Because Observation Haki was a combination of spiritual power and the five senses—amplifying the user's senses, a manifestation and extension of them—spiritual power played a key role before awakening.

But after awakening, the strength of Observation Haki was determined by the user's manifested five senses, and even more so, their sixth sense.

This explained how Katakuri, despite being only Yonko Commander level in overall strength, could train his Observation Haki to a level many Admiral-tier fighters couldn't reach—the ability to briefly 'SEE' the future.

For those not blessed with Katakuri's genius in Observation Haki training (aside from the initial awakening phase)—once their Observation Haki reached Pale Gold, significant improvement to their manifested senses, and thus their Haki intensity, could only be achieved through the 'Great Terror' of life-or-death combat.

Rowen hadn't yet faced such true life-or-death situations, hence his Observation Haki was the weakest of his three types.

But this very characteristic of Observation Haki also allowed for individuals like Aisa—born with exceptionally powerful innate Observation Haki of an extremely high level.

However, because Aisa was too young, her spiritual strength too weak, she couldn't control Haki of this magnitude... freeωebnovēl.c૦m

This was why, in the original story, Aisa couldn't control her Observation Haki, passively 'Hearing' and 'Seeing' voices and presences disappear, making her emotionally volatile and easily upset by others' arguments from a young age.

This kind of innate, super-powerful Observation Haki couldn't even be obtained through training—its detection range was immense.

One major reason Rowen desired the Rumble-Rumble Fruit was because its lightning-based abilities could vastly amplify the range of Observation Haki.

Enel's ability to use his 'Mantra' to monitor an entire country was solely due to the power of the Rumble-Rumble Fruit—

With such power, Rowen would hold absolute initiative on the seas.

Even if the World Government deployed all its forces to capture him, Rowen could detect them far in advance with his super-wide-range Observation Haki, deciding whether to engage or evade—completely controlling the terms of any encounter.

But Enel's vast sensory range was entirely due to his fruit amplifying his Haki.

Aisa's terrifying sensory range, however, stemmed purely from her own innate Haki—and Haki she couldn't even fully control yet! Just passively receiving feedback from it was this powerful! No wonder it was an Apex Gold tier Observation Haki.

What surprised Rowen even more:

Because he arrived bearing the 400-year promise, through the Strongest Trait System, he could use the combined spiritual power/obsession of Kalgara the Great Warrior and the Shandians' 400-year dedication to ring the Golden Bell as a conduit—TO EQUIP AISA'S OBSERVATION HAKI!

The principle was the same as when Rowen equipped Ace's Traits through Luffy.

And such equipping—could be completed instantly!

"Equip." Rowen didn't hesitate, mentally selecting the option.

——

—[Equipping successful!]—

—[Observation Haki Enhanced! Advanced to: Observation Haki (Apex Gold)!]—

——

Among his three Haki types, Observation Haki, previously his weakest link, instantly leaped to become Rowen's highest-ranked Haki in terms of pure tier!

From Pale Gold straight to Apex Gold!

VMM!

Rowen's Observation Haki spread out, and the terrifyingly vast range he could now perceive astonished even him.

It could easily cover an entire country!

And this was just his 'base' Observation Haki!

Once Rowen obtained the Rumble-Rumble Fruit and amplified it further with lightning waves... he couldn't imagine how horrifyingly vast his sensory range would become.

One thing was certain: After acquiring the Rumble-Rumble Fruit, Rowen would completely command the initiative on the seas...

Only battles Rowen chose to engage in would occur—enemies would only find him if he allowed it. Otherwise, on the vast ocean, not even the World Government could hope to track him down.

Such high-level innate Observation Haki, amplified by the Rumble-Rumble Fruit—was practically unprecedented on these seas.

This super-wide-range Observation Haki was akin to dominating information warfare on Earth—and on Earth, controlling the flow of information often decided the outcome of wars.

Mastering information warfare meant mastering the entire battlefield.

Possessing such Super-strong innate Observation Haki, further amplified by the Rumble-Rumble Fruit—meant Rowen had already won the information war.

Furthermore, after equipping Aisa's Observation Haki, Rowen's manifested five senses also received a massive boost.

The strength of Observation Haki was crucial for Logia users.

With sufficiently strong Observation—a Logia user could elementize just before a Haki-infused attack landed, allowing the attack to pass harmlessly through them.

But more importantly—

——

—[Observation Haki reached critical point! Born of the Sea (Apex Gold) facilitating manifestation of the Sixth Sense!]—

—[Observation Haki (Apex Gold): Possesses innate super-strong sensory range; can briefly 'SEE' the future.]—

——

Observation Haki trained to its absolute peak—manifested the user's sixth sense!

Utilizing this manifested sixth sense allowed one to briefly see into the future!

Because the sixth sense was such an abstract concept, exactly how Observation Haki manifested it was unclear; this step stumped countless Emperor/Admiral level powerhouses.

This resulted in very few individuals capable of 'seeing' the future with Observation Haki—even rarer than those who could use Infused Conqueror's Haki.

But now, after equipping Aisa's innate, super-strong Observation Haki, with the help of the Born of the Sea (Apex Gold) Haki training cheat code—Rowen directly bypassed this hurdle, achieving the manifestation of his own sixth sense!

From now on, in battle, he could briefly see the future!

The sensation was incredibly strange.

The sixth sense had always been one of humanity's most mysterious domains, a highly abstract concept. Yet, Observation Haki that had manifested the sixth sense could directly utilize this abstract conceptual power!

VMM!

Rowen briefly focused his newly enhanced Observation Haki. A flash of pure, intense red—distinct from the crimson-black of Conqueror's Haki—flickered in his eyes.

[Such strong Observation Haki? From this little girl?] In the future Rowen glimpsed, Luffy exclaimed this.

"Such strong Observation Haki? From this little girl?" Luffy now exclaimed, looking towards Aisa, who was hiding outside the tent.

Rowen's lips curved slightly. 'This ability to see the future... truly is strange and wonderful.'

<><><><><><><><>

"AISA!"

Wyper frowned upon seeing Aisa eavesdropping outside the tent. For her to listen in on such an important discussion was rather inappropriate.

"Eek!!!" Seeing Wyper, Aisa's small face filled with fear. To Aisa, Wyper was a terrifying demon, even scarier than God Enel.

Raki, seeing Aisa's fear, went over and gently hugged her, comforting her.

But Luffy and the others were now more focused on what Rowen had just said—strong Observation Haki.

Rowen's expression, his tone—both conveyed unprecedented amazement. For Rowen to be so astonished by this Observation Haki... one could only imagine how incredible it must be!

"Rowen! Are you saying this little girl, Aisa, possesses very strong Observation Haki?!" Sanji and Zoro stared at the frightened little girl, their faces filled with disbelief. (PS: Rowen said that at the end of the previous Chapter!)

How much suffering had they endured just to awaken Observation Haki?!

Initially, even after being relentlessly pummeled by Rowen using Armament Haki and various Devil Fruit powers for so long, they hadn't sensed any sign of Observation Haki awakening!

The concept of 'manifested five senses' was still too abstract for them before awakening it.

Only when Rowen used Haōshoku Coating, directly infusing vast amounts of spiritual power into their bodies and knocking them unconscious, did they finally awaken their respective Haki types.

Yet this little girl—so young—possessed Observation Haki that amazed even Rowen?!

"I wouldn't say very strong..." Rowen began.

His words made Zoro and Sanji sigh in relief. Being outdone by a little girl in Observation Haki would be too humiliating.

"—I should say, In terms of raw Observation Haki talent on these seas, she's undoubtedly among the absolute top!" Rowen, having benefited so immensely from Aisa, offered his praise generously, filled with genuine admiration.

"!!!" Luffy and the others stared dumbfounded at Aisa.

Who was Rowen?!

The man who could already preliminarily use Haōshoku Coating, fight head-on with Admiral-level, one of the absolute top-tier powerhouses on the seas!

Rowen's knowledge was astounding—it seemed there was nothing in the world he didn't know... For him to say this little girl's Observation Haki talent was supreme across the seas?!

"HEY! WANNA JOIN MY CREW?!" Luffy immediately stared eagerly at Aisa, extending an invitation.

BONK!

Nami instantly punched Luffy, teaching him some manners.

"I'm so sorry! He must have scared you! This idiot is like this sometimes," Nami apologized to Aisa with a bright smile.

"YOU MORON! SHE'S JUST A LITTLE GIRL! HOW CAN SHE GO OUT TO SEA WITH US?! IT'S TOO DANGEROUS!!" Nami then turned, transforming into her sharp-toothed angry state, lecturing Luffy.

"Th-That Observation Haki you were talking about... what is it?" Raki asked, hugging the frightened and somewhat bewildered Aisa, her own expression puzzled.

"Observation Haki, simply put, allows you to hear distant sounds, sense distant presences. Possessing such super-strong innate Observation Haki, yet being too young to fully control it—Aisa has probably been uncontrollably hearing sounds and sensing presences ever since she was born," Rowen explained, using Aisa's own power as an example.

Hearing Rowen's words, both Aisa and Raki stared wide-eyed.

"On Skypiea, this power is called 'Mantra'," Rowen added.

"Mantra?! The power those Priests and Enel use to control the entire country?!" Hearing this term, Gan Fall, Wyper, and the others all tensed, their pupils constricting.

They were all too familiar with Mantra.

It was because of this power that they were completely outmatched in their battles against the Priests—all their movements seemed to be predicted.

Enel, especially, could use Mantra to cover the entire country, keeping everything under his absolute control!

"Aisa's Observation Haki is actually stronger than Enel's. Enel's ability to cover the entire country is solely due to the amplification from his Rumble-Rumble Fruit. But Aisa is still too young to control such power; she can only use it passively and can't even unleash its full potential. When she grows older, she should gradually gain mastery over it. Then, she won't be uncontrollably hearing those sounds anymore," Rowen explained with a smile.

Aisa's Observation Haki was innately super-strong, very special, with an extremely vast range—and this was while she couldn't even consciously control the power yet!

In Rowen's hands now, its perceptive range, even without the Rumble-Rumble Fruit's amplification, was easily comparable to Enel's Mantra.

"Un-Unbelievable... So that's the truth behind this power," Raki murmured, looking at Aisa, seemingly relieved.

When Aisa uncontrollably heard those 'voices', she often appeared deeply distressed and frightened.

For a little girl, facing an unknown, uncontrollable power within herself was naturally terrifying.

And the experience of uncontrolled Observation Haki was extremely unpleasant—the constant barrage of others' emotions—even Koby nearly broke down from it during the Summit War, let alone a little girl like Aisa.

Knowing that Aisa would gradually gain control as she grew older brought Raki immense relief—after all, the unknown is what's most frightening—knowing the truth about Aisa's power was reassuring.

<><><><><><><><>

"M-Mr. Rowen... you said earlier that our Shandian people's 800-year mission is complete... What did you mean? And how did you know... we are the writers of history?" The Chieftain, finally recovering from the shock of Rowen's earlier words, now looked nervously at Rowen.

This was the Greatest secret of the Shandians, of Shandora!

Robin's gaze also fixed intently on Rowen. 'The ones who write history'—that phrase resonated deeply with her.

"It's exactly as you think. The Shandora where the Shandians reside holds a Poneglyph. Protecting it for generations—that is the true mission of the Shandians, of Shandora. Eight hundred years ago, you were allies of Joy Boy, fighting together against the World Government,"

Rowen stated, looking at the assembled group, dropping another bombshell.

"PONEGLYPH!" Robin's eyes instantly lit up.

"This Poneglyph, like the one in Alabasta, records the location of one of the three Ancient Weapons—Poseidon," Rowen continued.

His words made Robin's expression fall slightly. 'Not the True History then?'

"However... the information from this Poneglyph here has already been guided to the final island, Laugh Tale, by the Pirate King, Gol D. Roger. Your mission—can be considered complete," Rowen finished, smiling at the Shandian Chieftain.

"ROGER?! DID YOU SAY ROGER?!"

Gan Fall suddenly exclaimed, standing up.

"Sky Knight! You know Roger?" Luffy's eyes lit up.

(Rowen had previously explained to them who the Pirate King was, and why their history was now 'guided to the right place'.)

"Ah... many years ago, Roger came here, just like you, riding a monstrous current. We became friends. He was a very generous man. I never imagined he would become the Pirate King," Gan Fall reminisced, his expression filled with nostalgia.

"So... the history we guarded, has truly been guided to where it belongs?! Our mission—is really complete?! We don't need to fight anymore?!" The Shandian Chieftain trembled, his voice choked with emotion.

"Correct," Rowen confirmed with a solemn nod.

The Shandian Chieftain instantly burst into tears, overcome with emotion.
