Fleet Admiral? He Was Only Fit to Teach Him One Lesson

"It's fine."

"Rosen still doesn't know how to use Conqueror's Haki Coating."

"When it comes to Haki Coating, I can still teach him."

After noticing that Rosen's Conqueror's Haki had already reached the intermediate level, Sengoku consoled himself inwardly.

Conqueror's Haki Coating.

That was the technique that truly allowed Conqueror's Haki to unleash its terrifying power.

Without Conqueror's Haki Coating, unless one possessed advanced Conqueror's Haki, no matter how strong their Conqueror's Haki was, it could only be used to clear out fodder.

It simply could not display its proper power in actual combat.

"You'd better put away that little bit of wishful thinking in your heart!"

"Sengoku, you should know very well that one of the prerequisites for mastering a technique like Conqueror's Haki Coating is intermediate Conqueror's Haki."

"That kid called Rosen has already met the threshold for mastering Conqueror's Haki Coating."

Garp seemed to have seen through Sengoku's thoughts and directly shattered his hopes.

"Once that kid learns that Conqueror's Haki can be used like Armament Haki, coating one's limbs and weapons for attacks, then judging by the Haki talent he's displayed so far, he'll very likely learn it on his own."

"Understand? Even you, the Fleet Admiral, can at most teach him one lesson now."

"No more than that."

As soon as those words were spoken.

A sense of urgency rose in Sengoku's heart as well.

No matter the world, the debt of receiving teachings and guidance was immense.

Especially in the pirate world, where individual strength reigned supreme, that debt was even greater.

After learning of Rosen's existence from Zefa, Sengoku had already planned to use the debt of teaching and guidance to deepen Rosen's sense of belonging and identification with the Navy.

There was no helping it.

Other Navy members, even students from Zefa's class, had spent at least a year at Navy School.

That was enough time for them to develop a sense of belonging toward Marine Headquarters.

But Rosen was different.

His rate of progress was too fast.

At his current pace, half a year—no, three months—no, that was still too long. One month.

Rosen would be fully capable of graduating from Navy School.

And he could not remain there without graduating, either.

Because by then, from Admirals to the Fleet Admiral, there would be no one left who could teach Rosen about Haki, physical techniques, or the development of his Paramecia Ability.

"No."

"I must get ahead of Rosen and teach him this technique before he figures out Conqueror's Haki Coating by himself."

With that thought, Sengoku immediately used his Paramecia Ability.

Amid bursts of golden light shooting straight into the sky, he transformed into a Great Buddha, then stomped the air with Geppo and accelerated at full speed.

"Why did Teacher Sengoku transform?"

"Did Marine Headquarters come under attack?"

"Was it the escaped Golden Lion?"

"Or Kaido?"

Kuzan, who had arrived late, happened to catch sight of Sengoku's glittering golden back and immediately assumed a guarded stance.

"Nothing happened."

"It's just that, Kuzan—"

"You missed a lot of interesting things."

Garp patted Kuzan on the shoulder, signaling for him to follow.

He could have told Kuzan about it, but experiencing it firsthand and hearing about it from someone else were completely different matters.

On the other side.

Rosen had already completely withdrawn the Conqueror's Haki that had spread out and covered Navy School.

"Just as I thought."

"I have Conqueror's Haki."

"And Haki Supreme Art can be applied not only to Armament Haki, but also to Conqueror's Haki."

While Zefa had gone to the Fleet Admiral's office to report to Sengoku, Rosen had nothing to do, so he used Haki Supreme Art and tried pouring his consciousness into the other light orb within his body.

He had thought it was Observation Haki, but it turned out to be Conqueror's Haki.

The moment his consciousness entered his Conqueror's Haki, it began to run wild. Like a volcano that had been sealed away for years, it completely erupted after accumulating terrifying energy.

If Armament Haki was flowing water, then Conqueror's Haki was lightning.

It was extremely violent and difficult to control.

Even Rosen had spent a full five minutes after awakening his Conqueror's Haki before perfectly mastering that incomparably violent power.

Only then could he control Conqueror's Haki as freely as he controlled Armament Haki.

Then, as a matter of course, he crossed past the beginner stage and entered the level of intermediate Conqueror's Haki.

"I have Armament Haki, and I've even comprehended the fifth technique."

"I can also freely control Conqueror's Haki now."

"In that case, I can try Haki Coating."

Rosen revealed an eager expression.

The greatest teacher in the pirate world, Teacher Kai, had personally said it.

Conqueror's Haki Coating was something only a very small number of top-tier powerhouses could achieve.

If possessing Conqueror's Haki represented the potential to become a king, then mastering Conqueror's Haki Coating meant one had already become a king.

It was the mark of a top-tier ruler.

Since he possessed Conqueror's Haki as well, he had to master Conqueror's Haki Coating.

Just as Rosen was about to pour his consciousness into his Conqueror's Haki and then control it like Armament Haki, coating it over his heel, the tightly shut door was suddenly blasted open. Immediately afterward, a fierce gust of air rushed at him.

Before he could look around, bursts of dazzling golden light had already stabbed into his eyes.

"Y-You are?"

Rosen stared blankly at the golden Buddha in front of him, which had first blasted apart the door and then smashed through the ceiling.

He had only practiced his Conqueror's Haki for a while.

Was there really a need for the Fleet Admiral to personally come looking for him?

"Nice to meet you. I'm Sengoku."

"The Fleet Admiral of Marine Headquarters."

"However, you can call me Teacher Sengoku."

The moment they met, Sengoku introduced himself with a pleasant expression, then without another word forcefully established their teacher-student relationship.

"Teacher Sengoku?"

Three question marks appeared in Rosen's mind.

Wasn't Sengoku a Fleet Admiral?

Was his work not busy enough that he planned to take on a part-time teaching job at Navy School too?

But what did that have to do with blasting apart the door, smashing through the ceiling, transforming into a Great Buddha Form, and descending before him?

Honestly.

If he had not sensed no killing intent from Sengoku, and if Sengoku had not immediately withdrawn from his transformed state after appearing, Rosen would have suspected that he had run into one of those cases where the outstanding were inevitably crushed by the winds.

Had he shown off too much and drawn Sengoku here to teach this show-off a lesson?

"Here's the situation."

"Zefa already told me about you. I guessed that you probably possessed Conqueror's Haki, so I came to teach you how to properly use this power."

"After all, although Zefa is a rare and excellent teacher, he does not possess Conqueror's Haki."

After briefly introducing himself, Sengoku immediately began teaching.

"Not bad. Your Conqueror's Haki has already reached the intermediate level."

"I assume you've noticed that this power is extremely violent and powerful, yet it also seems scattered, unable to display its proper might."

"That is because you lack a key to open the door sealing away the true power of Conqueror's Haki."

He spoke in a methodical manner.

"Um, Fleet Admiral Sengoku."

"Hm?"

"Teacher Sengoku, actually, I've already thought of—"

"Enough. You don't need to say anything. Come with me first."

Before Rosen could finish speaking, a red glint flashed through Sengoku's eyes, and his expression changed drastically.

He no longer gave Rosen a chance to speak. He transformed into his Great Buddha Form once again, then, relying on both his strength as Fleet Admiral and the size of his Great Buddha Form, directly grabbed Rosen and carried him outside.
