Observation Haki

[Hmm? That energy again.]

Ra keenly sensed the energy emanating from the Armament Haki, its nature identical to what Kaido had used before.

"Croak! That hurts! What kind of power is this?"

Oshi clutched her nose, tears involuntarily welling up as she looked at Burufatt's calves and arms. She had clearly noticed the Haki's presence as well.

"Hmm? Kid, you don't know Haki?"

"Should I know it?"

Oshi rubbed her slightly reddened little nose, her tone carrying a hint of grievance.

"Ho~ Since that's the case, let me, a senior, teach you!"

"Fish-Man Karate, Consecutive Thousand-Tile Standing Fist!"

Burufatt, having already roughly gauged the opponent's physical strength, showed no mercy.

In an instant, countless fists wrapped in Armament Haki struck towards Oshi, but she dodged each one with her astonishing dynamic vision and reaction speed.

"Don't dodge! Getting hit is the fastest way to awaken Armament Haki! Feel my Haki attacks with your body."

"Are you trying to fool me?! Only an idiot wouldn't dodge!"

"You think you can trick me into taking a beating with this kind of trickery? You're about 20,000 years too early, Bull-Head Uncle!"

Oshi hopped left and right, narrowly dodging every fist.

"You brat! In that case, Fish-Man Karate—Misty Trace Fist!"

Seeing that his normal attacks were having little effect, Burufatt decisively used a technique from his Fish-Man Karate training.

Droplets of water seeped from his large palms, instantly transforming into mist with his high-speed punches, completely obscuring Burufatt's movements.

"Croak! How despicable!"

Unable to see the direction of his punches, Oshi was now being pummeled and could only wildly block with her hands.

Obe, watching Oshi being tossed around like a ball of dough, took a step forward, unable to stop herself from rushing in, but Ra's hand stopped her.

"Big Sis? You..."

"Don't worry, attacks like these won't hurt Oshi." Ra was confident in Oshi's physical defense.

"Since it's a rare opportunity, let her properly experience what combat feels like. She'll be doing this a lot in the future."

"Uh... Even so, her just taking hits like this isn't a solution."

Although they often bickered, Obe couldn't stand seeing Oshi being used as a punching bag by a stranger.

"That's true."

Ra thought for a moment and agreed that just taking hits wasn't very effective. She then spoke up to remind Oshi:

"Oshi, don't try to catch the opponent's attacks with your eyes. Use your consciousness to sense their energy."

This was a method Ra had figured out during her fight with Kaido, predicting the opponent's movements by sensing the flow of energy within their body.

Her current body, infused with Divine Power, had extremely high resistance and adaptability to external energies.

High resistance meant reduced damage or even complete immunity to energy attacks. For example, Ra was completely immune to fire and other extreme temperature attacks.

High adaptability, on the other hand, meant that the three of them could easily achieve things in energy manipulation and perception that were difficult or even unimaginable for ordinary people.

It was like how a user of the Mera Mera no Mi couldn't weave a piece of clothing that looked perfectly normal, unlike Ra who could use flames to do so.

This was a difference in magnitude in the precision of self-energy manipulation.

Returning to the present, Ra's instruction for Oshi to sense Burufatt was essentially telling her to utilize the body's sensitivity to energy fluctuations and grasp the opponent's movements without using her eyes.

However, Oshi, who was in the middle of being beaten, didn't have the composure to fully grasp Ra's meaning.

"What energy? How do I sense it?"

"People, animals, rocks... all objects possess energy.

Even though you can't see or touch it, just like the Divine Power within us, it can be sensed."

"Don't you already sense the flow of energy within your body? Try using the same method to sense external energy.

Don't rush. First, close your eyes and rely on your body's sensations. It's not difficult."

To help Oshi understand more accurately, Ra spoke in Chinese, so Burufatt didn't understand what she was saying.

Otherwise, he would have immediately realized that Ra was describing the method to awaken Observation Haki.

It was just that Ra had replaced the vague concept of sensing 'presence' with the concrete term 'energy'.

Ra meticulously explained the principle of sensing to Oshi, patiently guiding her step by step to master the ability to perceive external energy, much like teaching a baby to walk.

Of course, this was if one ignored Oshi's screams of pain in the background.

"Close my eyes and rely on my senses? Sister Ra, are you joking?"

This manga-like solution made Oshi wonder if she had somehow offended Ra at some point.

"Forget it, I can't dodge with my eyes open anyway. I'll give it a try."

With the mindset of "might as well go all out," Oshi closed her eyes and clearly felt the punches hitting her body become even more painful.

One punch, two punches, three punches… her shoulders, cheeks, forehead…

[Perception, Energy, Sensation]

Gradually, after taking an unknown number of hits, Oshi, who had grown accustomed to the pain, began to notice faint glimmers of light emanating from the fists striking her.

[Is this the energy sister La mentioned?]

Finally catching a glimpse of the basics, Oshi immediately focused her mind.

More points of light appeared on Burufatt's body, gradually spreading from his fists to his entire body.

In Oshi's consciousness, Burufatt's figure became clearer.

[No wonder his fists became so hard, it turns out he's wrapping them in special energy~]

Noticing the difference between the light on Burufatt's fists and the rest of his body, Oshi was the first to grasp the secret of Armament Haki.

Having mastered energy perception in a short time, she eagerly sounded the horn for a counterattack.

"Haha! Your moves are useless against me now, it's my turn next!"

"Eat my Thunder Cannon!"

Oshi dodged Burufatt's fist with a sidestep, then accurately struck his abdomen with a mini Thunder Cannon from her left hand.

"Wh—!"

Burufatt, caught completely off guard, was sent flying backward.

However, with his extensive combat experience, he agilely twisted his body in mid-air and landed steadily. Nevertheless, wisps of white smoke rose from his abdomen.

"Roar~ He managed to defend in time?"

Oshi sensed that the opponent had gathered energy in his abdomen just before being hit.

This instinctive action was something Burufatt had honed through countless battles.

[He awakened Observation Haki first?]

Burufatt, straightening his body, touched his slightly stinging stomach with a hint of surprise on his face.

[I initially thought I could beat Armament Haki out of him.

Impressive, what a gifted kid. No wonder boss Kaido recruited these girls.]

"Hey! Uncle Burufatt, are we going to keep fighting?" Oshi said, blowing on her small fist.

"No need. I have a general understanding of your strength, and you are indeed worthy of an Executive position."

"However, you still can't use Armament Haki. You're still a long way from the battlefield."

Having roughly gauged the opponent's strength, Burufatt lost interest in continuing the fight.

"By the way, that lightning just now, are you an ability user?"

Oshi's innocent face, full of question marks, was his only response.

"So what have you been talking about, Uncle? What's Haki, what's an ability user?"

"Could you please explain it to us, Mr. Burufatt? The three of us have been on an isolated island, so we're quite unfamiliar with these terms."

Seeing that the two had stopped fighting, La stepped forward at the opportune moment to ask him about Haki and ability users.

After all, this seemed to be related to the power system of this world and was quite important.

"Alright, looking at your clothes and age, you don't seem like people who would know about these things. Come with me first."

With that, Burufatt prepared to lead them into his residence. Of course, before leaving, he didn't forget to tell Deke, who was staring blankly beside them, that he was free to go.
