The chapter opens with a full-color spread titled "Chapter 520: \"THE GORGON'S EYE\"." The Straw Hat crew relaxes in a lush banana grove around a picnic table and wicker chairs. Luffy laughs while holding playing cards, Nami and Robin sit nearby with cards of their own, and Usopp, Sanji, Franky, Brook, Chopper, and Zoro occupy the rest of the scene in playful poses. A spotted giraffe-like animal and banana trees fill the background, with bright fruit and drinks scattered around the table. The image is an illustration extra rather than a story scene in Amazon Lily, but it clearly presents the chapter title and a cheerful crew tableau before the arena battle resumes. The manga-hosting footer below the artwork is unrelated boilerplate.

This page is mostly blank white space with a tiny cropped bonus panel near the lower half. The small drawing shows a cute animal-like doodle or mascot with raised arms inside a narrow manga panel. There is no readable story dialogue, title text, or character interaction beyond the little illustration. The manga-hosting footer text at the bottom is boilerplate and is not part of the chapter content.

Luffy crouches low, steam curling from his body as he prepares to escalate the fight: "Gear" and then "Second"!!! The arena erupts in confusion. Spectators ask, "What's that...?" and "Smoke's coming out of his body!!" while others gasp, "Can men... do that!?" Hancock watches silently, and Sandersonia and Marigold remain guarded rather than frightened. Marigold tells her sister, "There's nothing to be scared of, Mari..." and Sandersonia answers, "That's right." The page marks the start of Luffy's Gear Second form in the Amazon Lily arena: his body gives off steam, the crowd cannot understand what they are seeing, and the sisters prepare to test whether his speed can overcome their Haki and snake forms.

Sandersonia judges Luffy's new power from the start: "If he can't control that gigantic Haki, then it's just spirit!!" She begins "Snake Hair Possession!!!" and her hair transforms into many hissing snake heads, the note explaining that the kanji means an eight-branch great snake, also called by Susanoo in Japanese folklore. Sandersonia names the attack "Yamata no Orochi!!!" and drives the mass of living hair at Luffy. The crowd cheers, "KYAAA, go!! Lady Sandersonia!!!" while Luffy dodges through the attacking heads with "WAAH" and "HYUN!!" The page shows the sisters shifting from simple strikes to a more elaborate serpent technique, with Sandersonia's hair becoming a many-headed weapon that fills the arena around Luffy.

The snake hair smashes into the arena barrier, and the crowd panics: "The fence around the arena...!!!" Onlookers realize, "Those snakes are made from hair... but they're... like steel fangs!" Sandersonia's hair-heads tear through the stone and wood with repeated crashes and "HYUN!!" sounds. Luffy moves at high speed, but she keeps tracking him. He thinks, "Why can't I hit him!? I'm reading his moves but I can't...!!" while another voice admits, "I can't keep up!!!" The page shows that Haki prediction alone is no longer enough against Gear Second. Sandersonia can sense Luffy's intent, but his speed makes the future she reads difficult to answer, and the arena begins collapsing under the missed strikes.

Luffy vanishes between attacks and reappears with a burst of speed, slamming into Sandersonia before she can properly react. The impact tears up the stone floor with a huge crash and sprays debris across the platform. Sandersonia, Marigold, and Hancock all stare in shock, each marked by a tense "...!!" Luffy's expression is focused and severe, steam still rising around him from Gear Second. The page is mostly action and reaction, but it makes the change in momentum clear: the sisters had controlled the fight through Haki, poison, hardening, and coordinated attacks, yet Luffy's new speed lets him break through the rhythm and land a decisive hit before their predictive advantage can fully save them.

06
Luffy drives Sandersonia across the arena with a fierce rush, and she cries "OOO-OHH!!!" as her huge serpent body skids over the tiles. He continues the assault with high-speed movement, then begins another attack: "Gomu Gomu..." Marigold raises her crossed arms and warns, "It's futile! You saw how I reflected your attack earlier!!" She believes the same defense that bounced his previous blow will stop him again. Luffy's grin shows that Gear Second has changed the calculation. The page sets up a direct test of his upgraded force against Marigold's Haki-reinforced guard: earlier his rubber strikes rebounded, but now his speed and power are concentrated into a stronger technique.
Monkey D. LuffyBoa SandersoniaBoa Marigold
07
Luffy completes the attack: "Jet Bazooka!!!" His palms blast into Marigold's guard at high speed, overwhelming the defense she expected to reflect him. Marigold reels backward with "OOOHH...!!!" and crashes across the arena with a heavy "BOKOOON!!" while the crowd and sisters react in disbelief, "!!?" Sandersonia looks stunned as Marigold's massive king cobra body is knocked away. The page demonstrates that Gear Second's attacks can pierce the advantage that made Luffy's earlier blows useless. Marigold's confidence in her Haki-reinforced reflection fails against the sudden speed and force of Jet Bazooka, and the execution match starts tilting in Luffy's favor.

A stunned silence falls across the coliseum. Luffy stands steaming on the platform while the spectators stare open-mouthed, unable to believe both sisters have been staggered. The central arena gives off rubble sounds like "MUKUN" and "GARARA" as the combatants recover. Hancock finally snaps, "...Sonia!! Mari...!! What are you doing? What are you playing around for...!!?" Sandersonia, sweating, apologizes: "I... I'm sorry, sister!!! We'll finish him off right away...!!" Marigold answers, "R... right, sister...!!!" The page pauses between phases of the fight. Hancock's irritation replaces the crowd's worshipful cheering, and the sisters are forced to admit that Luffy is now dangerous enough to embarrass them in public.

Marigold powers up with fire around her body and a heavy "SHUBO!!" Luffy notices immediately, shouting, "!! She's on fire!!" Sandersonia resumes "Snake Hair Possession..." and Marigold releases a fiery technique named "Salamander!!!" with the note "snake god of fire." Her burning cobra body and flames surge across the arena while Sandersonia's hair snakes continue to menace Luffy. The page shows the sisters combining their serpent motifs with new elemental pressure: Sandersonia controls the battlefield with many-headed hair while Marigold turns herself into a blazing threat. Luffy must now deal not only with speed-reading and hard attacks, but also with open flame and a coordinated two-sister assault.

Sandersonia tells Marigold, "Don't give him anywhere to escape...!!" and attacks again with "Yamata no Orochi!!!" Luffy stands before the many snake heads as they surround him, steam rising from his body. The crowd, thrilled by the sisters' apparent comeback, shouts, "This is their best attack!!!" and, "No matter how quick he is, he won't get away!!!" Luffy exhales with a small "fu..." and calmly starts "Gomu Gomu..." while the snake mouths close in from every direction. The page sets up the sisters' strongest combined enclosure against Luffy's fastest multi-hit counter. The Kuja believe the net is finally too tight for him, but Luffy's focus suggests he has already chosen his next move.

Luffy unleashes "Jet Gatling!!!" in a huge double-page-style spread, his fists multiplying into a storm of high-speed blows that hammer through Sandersonia's snake hair and Marigold's defenses at once. The impact fills the arena with explosive sound effects and repeated strikes, while the left-side panels show the crowd gasping in disbelief and the sisters being caught inside the barrage. The attack overwhelms the sisters' coordinated best move by sheer speed and volume. Sandersonia's many hair-snakes are smashed apart, and Marigold's burning cobra body is driven backward as Luffy stays planted in the center of the storm. The spectacle turns the audience's confidence into shock, making clear that Gear Second has fully reversed the flow of the execution.

After the Jet Gatling, Marigold crashes into Sandersonia while still burning, and someone screams, "KYAA-AAA!! HOT!!!" Marigold yells, "Damn!! Sister Sonia!!" while Sandersonia cries out in pain. The fire and tangled serpent bodies pull them together: "Wait!! I'm getting pulled back!! What!?" and "I'm getting pulled towards Sonia!!" Another voice shouts, "Quick, move away!!" but Luffy has already tied their tails together. The sisters slam into each other with a huge impact, and both cry, "AHH!!! Our tails!" and "When did he!?" The page reveals that Luffy used the chaos of his high-speed attack not only to damage them, but also to knot their tails and create the next crisis.

The tangled sisters slide toward the spike pit. Marigold cries, "Hot!! It's so hot, help me!!!" and, "Wait, sister!! We're going to...!!!" Sandersonia shouts, "Sonia!! Look out, the spike pit's there! Grab onto the seats!!" The crowd panics, "Lady Sonia!!" as Sandersonia dangles over the edge, saved only by clinging to the wall. Luffy looks down in surprise while spectators call, "L... Lady Sandersonia!!?" and Sandersonia pants, "Haa... haa... Th... that was close..." The page shifts danger from Luffy to the sisters themselves. His counter has left them tangled, burned, and almost thrown into their own execution pit, exposing how quickly the public death match can turn against its enforcers.

14
The crowd misreads Luffy's next movement and screams, "...!!! He's trying to finish her!!!" and "That's not fair!! He's trying to skewer Lady Sonia!!!" Luffy leaps down toward Sandersonia, who is hanging near the spike pit, and she snaps, "You damn man...!!" He commands, "Don't move!!!" while still panting from the battle. Luffy then clarifies, "Even if you're trying to kill me...!! I have no intention of killing you...!!" Sandersonia is stunned, and Marigold orders, "You impudent bastard!! Mari!! Get him now!!!" The page shows Luffy rejecting the execution's logic. Even after the sisters used Marguerite as a hostage and tried to kill him, he refuses to finish Sandersonia off while she is helpless.

Marigold rushes in, asking, "What are you doing, Mari!?" while Sandersonia says, "I can't, Sonia...!! ...Right now, we're..." A spectator notices the real danger: "Look!! Lady Sandersonia's clothes have been burnt and her back is bare!!" Another warns, "If that man moves away, the Gorgon's Eye will be exposed!!" Luffy is holding himself over Sandersonia's back, shielding it from the crowd with his body. Sandersonia realizes they are "being protected... by that man...!!!" The page reveals why Luffy told everyone not to move: he is preventing the secret mark on Sandersonia's back from being seen. The hidden "Gorgon's Eye" that gives the chapter its title is not a monster power but the shameful back mark the sisters would rather die than reveal.

Luffy, still covering Sandersonia's back, remembers Hancock's earlier words: "We would rather die than let anyone see what is on our backs...!!!" He tells Sandersonia plainly, "You don't want anyone to see what's on your back, right? So don't move." Hancock's expression shifts as she realizes what he is doing. She immediately stands and orders, "We're done here!! Before the Gorgon's Eye is revealed!!! Everyone, leave the coliseum!!!" The crowd erupts in confusion and panic, with Marguerite's friends crying, "Oh no...!!!" and the spectators beginning to move. Hancock's command ends the public execution not because Luffy is defeated, but because protecting the sisters' hidden mark has suddenly become more important than killing him.

The crowd rushes "Out of the coliseum!!!" while women shout, "Hurry, hurry!!" and "We're going to be turned to stone!!!" Others panic, "It's the Gorgon's curse!!!" Sandersonia, still covered by Luffy, asks in disbelief, "I was fighting against you... why are you helping me?" Luffy answers simply, "What you don't want to be seen has nothing to do with our fight." He keeps shielding her back while the arena empties. Hancock lowers her head and wipes at her eyes or face with a trembling hand, the sound "PORO..." suggesting tears or an emotional break. The page closes the battle on Luffy's compassion rather than victory: he protects the secret of enemies who tried to execute him, and Hancock can no longer read him as merely an insolent man.

This is an SBS corner page. A decorative header shows a snake-like design and a small Luffy figure, followed by reader questions and Oda's answers. One reader asks about chapter 519's title page and whether the darker cover tone was a message about reaching the same chapter count as Akira Toriyama's Dragon Ball; Oda says it was more a message for himself and talks about One Piece running longer because it has more pages per chapter and because he has expanded the story without wanting to leave loose ends. Another reader asks about CP9, the six powers, and whether Oda surpassed Rokushiki and Nanashiki to create an eighth technique; Oda jokes that he has the legendary Nanashiki user and names "Chokkai," explaining the gag about meddling and "direct shell." A final reader asks where Oda would like to travel, but the page ends with Oda saying, "See you next volume, SBS!" The footer is manga-hosting boilerplate and ignored.
