Enrolled for Two Days, Graduated?

"First, Finger Pistol."

Zefa shot forward in a sudden stride. Without using Armament Haki, he relied solely on physical strength to punch a finger through a reef on the beach.

"This is Tempest Kick."

His right foot rose from the ground like a blade leaving its sheath, then chopped down toward the sea from above.

Amid a piercing whistle like the ring of a sword, a visible vacuum Slash Wave shot through the air like a bird, cleaving open both the beach and the sea and leaving behind a deep fissure.

"This is Shave."

Zefa appeared to stamp his feet once, but in reality, he had stepped dozens of times in an instant. Like an arrow loosed from a bow, he vanished from where he stood, kicking up a cloud of sand and appearing fifty meters away as though he had teleported.

"Then comes Geppo."

He stepped into the air, his feet treading on empty space as though it were level ground. Like climbing a staircase, he ascended step by step into the sky before walking back down again.

"Next is Kami-e."

Zefa relaxed his strength, and his body swayed with the wind. Like he was wearing a paraglider, he flew freely through the air.

"Lastly, Tekkai."

With a thought, every muscle in his body seemed to be infused with endless strength. From skin to flesh, every part of him became as hard as steel.

Even cannonballs would struggle to harm him in the slightest.

However.

Rosen watched the first five of the Six Styles with complete focus, but when it came to Tekkai, he simply turned his head away, too lazy to spare it another glance.

That mysterious Tekkai.

Other than giving its user a mysterious confidence, it had no other use.

Its main feature was that whoever used it lost.

And that was indeed the truth.

Among physical techniques, Tekkai was only useful for freaks with abnormal bodies, like Teacher Kai and Big Mom.

Anyone else who used it would lose.

"Have you learned them?"

After demonstrating the Six Styles once, Zefa turned to look at Rosen.

When teaching other students, even monsters with an Admiral's Bearing, he taught them one technique at a time. But considering Rosen's Heaven-Defying Comprehension, he decisively chose the cramming method.

He only needed to perform the Six Styles once from beginning to end.

There was no need to explain any requirements or precautions.

Because that would be unnecessary.

"I've learned them."

Rosen nodded.

He had learned the Three Colors of Haki and all their techniques after hearing Zefa explain them once, even drawing inferences from them.

Not to mention the mere Six Styles, especially when Zefa had demonstrated them from start to finish.

"Don't underestimate the Six Styles."

"Most of these six physical techniques were created by drawing inspiration from Devil Fruits, Swordsmanship, and weapons."

"Tempest Kick draws from a swordsman's flying slash, Finger Pistol draws from rifles and cannons among weapons, Tekkai draws from the physiques of Zoan users, Kami-e draws from the flowing bodies of Logia users, while Geppo and Shave draw from the abilities of the Paramecia Spring-Spring Fruit."

Zefa seemed to have noticed Rosen's disdain for the Six Styles, or perhaps for Tekkai in particular.

"The Six Styles may not be overly powerful when used individually, but what if they are paired with the Three Colors of Haki?"

"Physical techniques and Haki have always complemented each other."

"And the reason I'm teaching you the Six Styles is because they are not only physical techniques, but also excellent methods of body training. Even after you master all six, repeatedly using them will continue to temper your body, especially when combined with your Six Warehouses Immortal Thief."

"Eating and training, both at once, will let you forge a monster-like body in the shortest possible time."

Zefa spoke with utter seriousness.

Hearing this, Rosen finally put aside his contempt for Tekkai—or rather, changed his view of it.

Tekkai was not for defense. It was for body training.

After all, attacks from top-tier experts—whether Devil Fruit users, Haki experts, or swordsmen—could shatter the ground and split the sea at a moment's notice. How could something like Tekkai possibly withstand them?

Only those idiots from CP9, along with a few individual talents in the Marines, would use Tekkai for defense.

"This will also be your final class at Navy School."

"Starting tomorrow."

"You won't need to attend classes at Navy School anymore."

After watching Rosen perform the Six Styles once in front of him, Zefa suddenly said this.

"Teacher Zefa."

"Do you mean I'm graduating?"

Rosen was slightly stunned.

He had only been enrolled for two days and attended a total of four classes.

And he was graduating already?

On second thought, it really did seem to be the case.

He had already learned the Three Colors of Haki, all Haki techniques, and physical techniques.

It could be said that he had learned everything Navy School could teach, as well as things Navy School could not teach.

Even a former Navy Admiral probably had little left to teach him.

"What are you thinking?"

"I only said that there's nothing useful left for you to learn at Navy School."

"I never said you could graduate."

Zefa glanced at Rosen.

"Then if I'm not coming to school for class and I can't graduate, where am I supposed to go?"

Rosen looked at Zefa in confusion.

"Tomorrow at eight, wait for me at the entrance of Navy School. You'll find out then."

Zefa did not answer directly and instead told Rosen to go back and rest.

If it were any other student, even a student from Zefa's class, they would have to undergo all kinds of group training on schedule. But Rosen did not need to.

It was not because Zefa was playing favorites. Rather, he knew clearly that aside from teaching Haki and physical techniques, giving Rosen back the rest of his time was the best way to nurture him.

After class.

Zefa did not return to Zefa's class, nor did he go watch Gion and Tokikake train. Instead, he went straight to the Fleet Admiral's office, knocked on the door, and made a request to Sengoku that stunned every high-ranking officer in the room.

"What did you say?"

"You want me to write you a pass allowing you to freely enter and leave Impel Down?"

"Zefa, what are you going there for?"

Sengoku looked puzzled.

"Besides a pass to enter and leave Impel Down, I also want an Exemption Order personally signed by you."

Rather than answer Sengoku's question, Zefa continued with a second request.

"What exactly are you planning to do?"

"Zefa."

"You haven't let go of the past, have you? Are you planning to go into Impel Down and kill prisoners?"

Sengoku frowned deeply.

The first thing that came to mind was the greatest pain of Zefa's life.

His family.

The former Non-Killing Admiral had never killed a single pirate during his operations. Yet in return, his family had been killed by pirates—his entire family.

From that moment onward, the Non-Killing Admiral had died.

What remained was an admiral who hated pirates.

Even after resigning from his position as admiral, that hatred for pirates had not faded. Instead, as time fermented it, it grew ever stronger.

"If I truly wanted to do that, I would have gone to Impel Down and slaughtered everyone before I retired."

"I wouldn't need to come here and ask you, Sengoku, for a pass and an Exemption Order."

When Sengoku mentioned his family, Zefa's expression couldn't help but shift slightly, but it quickly returned to its former indifference and severity.

"Then what is this about?"

Hearing this, Sengoku was relieved, but he still refused to sign without getting a clear answer.

After all, Impel Down was a forbidden place that imprisoned the evil of the world.

No matter how much he trusted Zefa, he would never casually issue a pass before learning the reason—let alone an Exemption Order.
