One Piece: Nobody knows Devil Fruits better than me.

Chapter 83 The Reverse-Reverse Fruit, the Gauntlet 'Black Mane'!
Several days later, at the Zephyr Training Camp, in the special training field.

"The grandfather and grandson are indeed of the same lineage; their vitality is truly astounding."

After hearing that Garp's warship had returned to port and that his injuries were only caused by a few bandages, Roy in the training camp sighed with emotion.

This sudden encounter between Pig and Garp allowed him to witness the monstrous vitality and power possessed by a top-tier ocean powerhouse at the Emperor level.

This calmed his slightly inflated ego.

But it was precisely at this moment.
"Click."

The training room door suddenly opened, and Binz walked in.

"Roy, you're here too. Huh!? What happened here?"

Upon seeing Roy, Binz was initially greeting him familiarly.

But halfway through his sentence, he suddenly froze.

Because he saw what was happening inside the training ground.

At this moment, the once flat and solid floor of the training room was covered with huge, spiderweb-like cracks.

Huge pits were everywhere in the walls, revealing extremely thick metal interlayers inside.

"Oh, it's nothing—I've been busy preparing for the military exercises these past few days, right? I just happened to make a tiny bit of progress in my cultivation, so I sparred with Master Zefa."

"That's what Roy said casually."

"Sparring?"

Binz's voice was extremely high-pitched: "But this training room was specially reinforced by SSG just last month by Coach Zefa."

He remembered it clearly—SSG had confirmed Roy's strength through Zephyr at the time and vowed that the training room would not be destroyed for at least a year.

How long has it been since?

What exactly are you referring to as "small improvements"?

And just as he couldn't help but ask that question...
"Binz? What's wrong?"

came a female voice.

Then, Roy saw a tall, beautiful woman with long, wavy, sea-blue hair walk in.

She had an X-shaped scar on her right leg, a pistol hanging at her waist, and wore a blue cloak.

"Oh, I almost forgot."

At this moment, Binz, still in shock, finally came to his senses.

He quickly looked at Roy and introduced him to the woman, saying, "This is Roy Amos."

“Roy, that’s her.”

He said so.

But in fact, he didn't need to introduce it.

At this moment, Roy naturally knew the other party's identity.

[The Devil Fruit user 'Ain' has been discovered]

[The Devil Fruit has been confirmed as the 'Paramecia-type Rewind-Rewind Fruit', and is currently being analyzed and stored in the 'Devil Fruit Encyclopedia'.]

[Devil Fruit Ability - Allows the age of things to be reversed]

[Effects at Each Level]

[LV3: Gain all fruit effects, and can ignite peach-colored flames in your hands. The flames themselves have no destructive power or heat, but things and creatures touched by the flames will regress to their past state, with a maximum regression of 15 years.]

[Note: This ability can be removed by defeating the ability user or exhausting their stamina. The stronger the opponent, the greater the stamina consumption. It requires 20 billion to permanently unlock.]

[LV4: Fruit Deep Development, the pink flames can spread to any part of the body, and the places touched will be pushed back. Requires 50 billion to permanently unlock]

[LV5: Fruit Awakening - Retreat Field, creates a field nearby with a maximum range of 2000 meters, can randomly generate flames anywhere within the field, consumes a lot of stamina, requires 110 billion to permanently unlock]

[Fruit Awakening - Unique - Time Field: This ability evolves the awakened field into a Time Field, reversing the time of everything within the field, including oneself. The reversal effect lasts for 5 hours and requires 300 billion Berries to unlock.]

[Note: This ability can only be used once, cannot be blocked in any way, and the timing of this rewind is completely random and cannot be controlled.]

The information from the Fruit Encyclopedia almost left Roy stunned on the spot.

Just as mentioned before, he knew that Ain's fruit, the 'Rewind Fruit,' was a very special time-related fruit.

But he never expected it to be this special.

"only"

Looking at the clear label in the fruit encyclopedia, Roy muttered to himself.

He did know that some fruits' abilities could only be used once—the most typical example being Terfalgar Law's 'Op-Op Fruit'.

The 'immortality surgery' performed by that fruit can only be used once, and it is said to require the user's own life to pay the price.

This 'Regression Fruit' is the second such fruit he knows of.

But
"This ability."

Roy was starting to have some doubts.

It reverses everything in the surrounding area, and the timing of the reversal is completely random and cannot be stopped in any way.

This ability sounds terrifying at first glance—it's almost like the ability to reverse time, which should be impossible.

But the problem is.
This ability's effect extends to the user themselves and is uncontrollable.

"Isn't this just playing with fire?"

Roy drew a conclusion.

He knew very well that the Rewind Fruit's ability to rewind was to 'return things to nothingness'.

For example, if Roy is 29 years old now, then if time were to rewind 30 years, he would simply disappear!
Even if the power were to wear off after five hours, he wouldn't be able to recover. Therefore, Roy could hardly think of any situation where this power could be used.

"Spend 300 billion Berries to take down nearby enemies together?"

He muttered in his mind.

But it is precisely at this moment
"Roy?"

Ayn walked up to Roy and greeted him.

"Senior Sister Ain."

Upon hearing this, Roy temporarily set aside the matter of the Rewind Fruit, letting the Fruit Encyclopedia analyze it while looking at Ain.

But Ain shook his head: "Neither Binz nor I are destined to inherit Teacher Zephyr's Black Body Style, so we can't be considered his true successors—you can just call me Ain."

Roy readily agreed, and the two quickly began exchanging ideas.

Ain was clearly a relatively serious person, and she quickly got to the point about her mission.

"My mission was supposed to have ended a month ago, but during the mission, I discovered something."

At this point, Ian clenched her fists.

Then she realized the real reason she had come and quickly asked, "Speaking of which—where is Professor Zephyr?"

After sparring with me, Teacher Zephyr suddenly went upstairs, probably questioning his existence. Well, of course, Roy wouldn't say that.

Just as he was about to find an excuse for Zephyr.
"I'm here."

Accompanied by a dull sound.

The three then saw Zephyr slowly walking down from the training ground.

"Professor Zephyr, I have something to report to you!"

Upon seeing Zephyr, Ain immediately gave a military salute.

"There's no rush yet."

But at this moment, Zephyr shook his head: "Before you report, kid Roy, here you go."

As soon as he finished speaking, the general raised his left arm and threw it away.

Only now did the three of them notice that Zefa seemed to have been holding something in his hand.

As Zephyr threw it, it landed in Roy's hands.

Roy quickly looked down and saw it.
"Boxing gloves?"

Looking at the pair of gauntlets in his hands, which had a faint obsidian feel, were extremely thin yet seemed incredibly tough, Roy looked somewhat astonished.

Meanwhile, Binz and Ian, standing to the side, widened their eyes in surprise.

"This is this"

Both of them clearly recognized the boxing gloves, and looked at Zephyr incredulously: "Teacher, are these yours?"

"Ah."

Zephyr looked at the gauntlets in Roy's hand and said softly, "They're called 'Black Mane,' the weapons I used when I was a general."

His face seemed to hold some memories.

"It is made from diamond-spun yarn specially made by Trisnor of 'Fabric Island', combined with SSG's seastone craftsmanship. It has a certain restraining effect on Devil Fruit users, and at the same time, it has a certain enhancing effect on the flow and binding of Armament Haki."

He grinned.

As mentioned before, he honed his Black Body style in his youth and preferred to fight with both hands, hence the nickname 'Black Arm'.

And these boxing gloves are from his comrades who helped him earn this reputation.

"Since stepping down as general, I have rarely used these two old buddies."

"As for now."

At this point, he smiled.

The three people present clearly understood what was meant—Zeffa, who had lost an arm and was already old, could no longer use the gloves.

So at this moment, Zephyr's gaze fell on Roy.

Those aged yet still resolute eyes shone with relief and anticipation: "I thought it would be a few more years before you were qualified to use it, but now it's yours."

"."

Upon hearing Zefa's words, Roy was naturally taken aback.

He naturally understood Zephyr's meaning—these gauntlets had a certain enhancement effect on Armament Haki. Although they were useful to Roy before, Roy was not truly qualified to use them.

But now that Roy has mastered Ryuo, he is qualified to use it.

"Teacher Zefa"

Looking at the old man in front of him, Roy spoke softly as if to say something.

But before he could even finish speaking, Zefa burst into laughter and punched him in the chest.

"Kid, don't think you've graduated just because of this. I'm only giving it to you because you're about to participate in the Three Armed Forces Military Exercise!"

He looked at Roy and grinned, "Don't disgrace it, kid."

Upon hearing this, Roy was stunned for a long time.

then
".certainly."

He smiled too.
