Loy Amos, a lieutenant in the Navy Headquarters and commander of the escort fleet warship *DT-31*.
Word was he hailed from the West Blue, joined the Navy at twenty, and had served for eight years now.
During his initial physical assessment at a local Navy branch, he had performed completely average, but after participating in the arrest of the Devil Fruit user Captain Tora the Giant Rhino in the West Blue, his strength began to soar.
That wasn’t unusual—plenty of Navy officers only began to shine after clashing with a formidable enemy.
Afterward, he was scouted directly by Navy Headquarters, passed the recruits’ evaluation, and voluntarily applied to join the Custody Unit.
—That was how the Navy officers in the escort unit knew Loy Amos.
In reality, what nobody knew was…
Loy Amos was actually a transmigrator from another world.
There was one thing the Navy members got right, though: Roy truly had his own brand of justice.
“Ice-cold Coke is justice!” Roy let out a satisfied sigh as he washed down a slice of pizza with a gulp of chilled happy water.
At that moment, he was watching the hourglass on his desk.
Just as he looked, the last grain of sand fell through.
And in his ears— [Paramecia: Strong-Strong Fruit has been added to the Fruit Encyclopedia.
Current Level: LV1] As the prompt sounded, the illusory screen in front of him shifted, morphing into an ethereal tome.
Upon its pages were illustrations of various uniquely shaped Devil Fruits.
[Paramecia: Cage-Cage Fruit – LV1] [Zoan: Ox-Ox Fruit, Model: Giant Rhino – LV1] [Zoan: Dog-Dog Fruit, Model: Dalmatian – LV1] [Logia: Glint-Glint Fruit – LV1] [Logia: Mag-Mag Fruit – LV1] [Logia: Ice-Ice Fruit – LV1] On the latest page, [Paramecia: Strong-Strong Fruit – LV1] was just finishing its inscription.
Then, the book snapped shut.
Embossed on the cover were two words: [Fruit Encyclopedia].
[Holder: Loy Amos] [Current Registered Fruit Types: 19 (Paramecia: 7, Zoan: 7, Logia: 4, Special Paramecia: 0, Mythical Zoan: 1)] [Fruit Slots: 2] [Currently Equipped: Ox-Ox Fruit, Model: Giant Rhino LV1; Human-Human Fruit, Model: Daibutsu LV1] [Current Berries Held: 41,130,000] “Nineteen Devil Fruits registered in the Fruit Encyclopedia at last.
Just one more to unlock the third fruit slot.
Plus, this guy’s Strong-Strong Fruit is actually a pretty practical ability!” “This trip wasn’t in vain.” These thoughts muttered in Loy’s heart were something only he could understand.
That’s right.
As a transmigrator, Roy had his own system: the Fruit Encyclopedia he was looking at right now.
True to its name, this system was tied to the unique treasures of the One Piece world: Devil Fruits.
The Fruit Encyclopedia consisted of two main functions.
The first was Recording and Equipping.
As long as he got close to a Devil Fruit user and spent time near them, he could record their Devil Fruit into the Fruit Encyclopedia.
If the user activated their power right in front of him, the recording process sped up significantly.
Once an ability was recorded, he could equip and use it through the system’s fruit slots.
He started with just one fruit slot, gaining an additional slot for every ten Devil Fruits collected.
Of course, if Roy obtained an actual physical Devil Fruit, he could absorb it directly, immediately gaining the ability at LV3.
The system’s second function was Ability Enhancement.
When a fruit was newly recorded, its base ability level was LV1.
Roy could then spend enough Berries or equivalent treasures to level up his fruit abilities.
Alternatively, he could spend a smaller amount—roughly one-third of the normal upgrade cost—to temporarily unlock a higher ability level for one hour.
Furthermore, because Roy hadn’t actually eaten physical Devil Fruits, the abilities he gained weren’t cursed by seawater or Seastone!
Loy’s assessment of his golden finger was simple: “Broken!” He knew full well how terrifying the Fruit Encyclopedia was.
It let him wield multiple Devil Fruit abilities without fear of seawater or Seastone.
It was a golden highway leading straight to the peak of the world.
Sure, Teacher Kaido rambled on about how “Haki reigns supreme over all,” but wasn’t the guy himself a user of the mythical Fish-Fish Fruit, Model: Azure Dragon?
Which brought up the real question: Where on these seas could one safely encounter enough Devil Fruits?
For Roy, the answer was simple: the Navy.
As the behemoth backed by the World Government that kept the Great Pirate Era from spiraling completely out of control, the Navy had the highest concentration of Devil Fruit users—and the most opportunities to encounter them.
So Roy chose to join the Navy, actively volunteering for the unpopular Custody Unit.
And time proved he was right.
Over these eight years, by interacting with Navy Devil Fruit users and occasionally escorting prisoner ability users, he had recorded nineteen Devil Fruit abilities.
This included the Logia powers of the current three Admirals, and even the top-tier Mythical Zoan Human-Human Fruit, Model: Daibutsu, belonging to Fleet Admiral Sengoku.
One could say that in terms of accumulating Devil Fruit abilities, Roy had already built up a formidable foundation.
Which left him with only one pressing problem: Namely…
“I need to figure out how to make money,” the Navy Lieutenant thought to himself.
Indeed.
As mentioned earlier, upgrading his fruit abilities required Berries.
The exact cost varied wildly depending on the fruit type, but followed one universal rule: the stronger the fruit, the higher the price.
Based on Loy’s current summary, upgrading a standard Paramecia or Zoan fruit to LV2 cost around 50 million Berries; LV3 required 200–300 million Berries; LV4 required 1 billion Berries; and an LV5 Awakening generally cost several billion.
Logia fruits were even more insane.
Upgrading a basic Logia like the Plume-Plume Fruit to LV2 took 300 million Berries, LV3 shot up to 1.5 billion, LV4 took 5 billion, and Awakening was an astronomical sum exceeding 10 billion Berries.
Top-tier Logia fruits like the Mag-Mag Fruit and Ice-Ice Fruit were pricier still.
As a side note, Loy’s monthly salary as a Navy Lieutenant was roughly 300,000 Berries.
Over his eight years in the Navy, even counting stipends and bonuses from prisoner escorts, he had only saved up a little over 40 million Berries.
“Even a model youth like me who doesn’t smoke, doesn’t drink, and whose only hobby is sipping Coke finds it this hard to save money…
*burp!*” Roy burped and sighed.
He was genuinely stressed over this.
“I’m broke!” Who would’ve thought he’d be stressing over the exact same thing both before and after transmigrating?
“If worst comes to worst, I’ll just leave the Navy once I hit twenty Devil Fruits and become a bounty hunter.
Running around is a pain, but at least the pay is way faster than staying in the Navy.” “Besides, even if all my fruit abilities are currently LV1, unlocking a third slot will be more than enough to handle the first half of the Grand Line.” Roy calculated in his head.
But right at that moment— *BOOM!* The cabin lurched violently, accompanied by shouts from outside.
Loy quickly steadied his chilled Coke and yelled angrily, “What’s going on?!
Who’s at the helm—Hans!
Are you trying to get fired?!” Shouting, he chugged the rest of his soda, opened the door, and stepped onto the deck.
He was greeted by chaos across the deck and sailors firing their rifles toward the water.
They were aiming into the sea.
Under the moonlit night sky, a behemoth broke the sparkling surface of the ocean.
It had the head of a lion, the body of a fish, and stretched tens of meters long.
Its massive eyes glowed in the darkness like burning embers.
“Lieutenant Roy, it’s a Sea Beast!
A massive Sea Beast is attacking us!” Sergeant Fal rushed up to Loy and reported frantically.
“A Sea Beast?” Loy raised an eyebrow.
As a naval fleet operating long-term in the Four Seas, the escort warships naturally had Seastone lining their hulls.
Normally, Sea Beasts and Sea Kings wouldn’t notice the warship’s presence.
But accidents happened—for instance, if a coastal Sea Beast or small shallow-water Sea King swam too close to the surface, it might spot this “lump of iron.” “Yes!
Looks like we’re out of luck today!” Fal looked ready to cry.
“Out of luck?
Isn’t this great luck?” Roy interrupted him.
“I recall Sea Beast meat fetching a pretty penny!” “Wh-what?” Fal blinked, unable to process his commander’s words.
Loy didn’t bother explaining.
“Everyone, cease fire!
If you ruin the prime cuts, you’re dead meat!” Every sailor on the warship froze in confusion.
Still, as trained soldiers, they reflexively stopped shooting.
“Sir, you…” Someone opened their mouth to ask.
But before they could utter a word, Roy moved.
*BOOM!* He bent his knees and leaped into the air!
The tremendous force caused the entire warship to tilt visibly for an instant.
Under the shocked gazes of all the sailors, Loy shot through the air toward the monstrous beast.
“Lieutenant Roy!” The navy men cried out in panic.
But a moment later, their panic turned into utter terror.
Because the Sea Beast had noticed Loy as well.
*”ROAR!”* The monster let out a low roar and charged at Loy with crushing power.
“We’re doomed!” “If he takes that head-on…
even the Lieutenant…” “Prepare rescue teams immediately!
Save the Lieutenant!” The sailors were losing their minds.
Yet in the very next second, the scene before them caused their eyes to pop out of their sockets and their jaws to drop to the deck.
There under the moonlight…
The Navy Lieutenant soared through the air, his coat emblazoned with “Justice” fluttering wildly in the wind.
He pulled back his elbow and cocked his fist!
Under the pale moonlight, every sailor saw his massive arm, looking as though cast from steel!
The muscles bulging beneath were forged like solid iron.
[Currently Equipped Fruit 1: Ox-Ox Fruit, Model: Giant Rhino LV1 – Minor ability, grants the physique of a giant rhinoceros, elevating body toughness and muscle density far beyond normal humans] [Currently Equipped Fruit 2: Strong-Strong Fruit LV1 – Minor ability, grants a 5x multiplier to muscular strength] Many knew that Zoan Devil Fruits granted their users powerful, beast-like physiques.
Gladiator Anatolia also knew his Strong-Strong Fruit boosted muscular power immensely.
But what if someone possessed both the baseline physical traits of a Zoan fruit *and* the muscular amplification of the Strong-Strong Fruit?
This moment was the answer to that question.
*BOOM!* Roy threw a single punch!
The wind pressure generated by his raw force compressed the ocean surface beneath him, carving out a massive trough!
In the next instant, his fist collided with the Sea Beast’s head.
And every sailor watched in disbelief.
That colossal Sea Beast, over a hundred meters long…
was blasted flying through the air by Loy’s single strike!
*”ROAR—!”* It let out a piteous screech before crashing into the sea, knocked completely unconscious.
Roy landed lightly atop the beast’s massive floating head amidst a chorus of bewildered “Eh?!
Eh?!
Eh?!” from his men.
Indeed.
This was why Loy wasn’t in a rush despite all his fruit abilities currently being LV1.
Because…
“Stacking Devil Fruits isn’t a simple case of one plus one.
As long as you understand enough Devil Fruits deeply, even LV1 abilities can produce unimaginable power!” Roy murmured to himself.
“And in this world, nobody knows Devil Fruits better than me!”
