A Weekly Shonen Jump magazine cover shows Luffy in the foreground with a yellow flag, surrounded by characters from multiple Jump series in a summer-themed collage. Other visible series promotions include Dr. Stone, Bleach, My Hero Academia, Sakamoto Days, and more. It is not part of the One Piece chapter narrative, but Luffy is prominently featured as a One Piece representative on the magazine cover, so the page is kept as useful extra front matter rather than ignored junk.

Chapter 1021 is titled "Demonio." The cover request by Rye reads: "Senor Pink and Franky sharing a drink at Hyo's bar." Franky and Senor Pink sit together at a bar with drinks and snacks while Hyo tends the counter. The page is a cover request rather than story action, but it preserves the chapter title and an official cover gag connecting Franky and Senor Pink after their Dressrosa fight.

Robin's Gigante Fleur is "in full bloom" in the great banquet hall. The gigantic upper body and arms of Robin rise around Black Maria, who sneers, "What a temper tantrum." Black Maria observes that "that big thing" must be taking a lot out of Robin, but Robin, still panting, answers, "Don't worry about me... I plan on settling this quickly!!" She forms many huge hands and arms into a flowing constricting attack around Black Maria, calling "Sea Serpent!!" The hall shakes as Robin's giant limbs coil through the space like waves. The page opens the chapter by showing Robin committing to a large-scale technique that can overpower Black Maria if she can end the fight before the strain and recoil catch up with her.

Robin's Sea Serpent rushes Black Maria with enormous arms and hands, but Black Maria withstands the pressure and crashes through the attack. She asks, "You think that'll make me give up?" Robin answers, "There's no escape," and follows with "Get a clue!!" as more giant limbs sweep in from every direction. Black Maria uses her weapon and spider body to batter the giant limbs, striking through the mass of Robin's created arms and forcing the pain back onto Robin's real body. The page reveals the weakness of Robin's enormous bloom: the technique gives her overwhelming reach, but the larger the limbs become, the easier they are for an enemy as strong as Black Maria to hit, catch, and punish.

Black Maria confirms the drawback by striking Robin's giant limbs and saying, "So, your real body gets injured too!!" She decides, "This is going to be a piece of cake!! These massive limbs are just bigger targets!!" Robin notices the danger when Black Maria adds that her legs are poison-tipped. Black Maria then spreads webbing across the hall with "Maria Net!!" and catches Robin's giant body and limbs in the sticky trap. Robin's main body reacts in pain and alarm as the huge projection is pinned. The page turns Robin's grand technique against her: Black Maria now has a method to restrain the larger body and attack it safely, using webs, poison, and the link between Robin's blooms and her real body.

Black Maria presses the advantage with "Maria Hush!!" and slams Robin's giant form through the hall. Robin tries to spread her arms and regain control, but Black Maria lunges into close combat, declaring, "I'm a martial artist at heart, and it's not like I need to hold back... since we're both women!!" The line makes her cruelty personal and dismissive; she treats Robin's giant bloom as both a challenge and a punching target. Robin's huge body reels under the blows while her real body feels the damage. The page shows that Black Maria is not only a trickster with illusions and webs, but also a strong close-range fighter willing to brutalize Robin once she understands how the Devil Fruit recoil works.

06
Black Maria launches a direct beating, shouting, "Taste my Oiran Knuckles!!" She punches Robin's giant form hard enough for the real Robin to cough blood and clutch her face. Black Maria laughs, "Ahaha, what a satisfyingly large punching bag!" and continues battering the projection from multiple angles. Robin's created arms try to retreat or guard, but Black Maria follows with more heavy strikes and mockingly says, "Oh my! Now you're the one trying to get away?" The page is a low point for Robin in the duel: her power has made her physically imposing, but Black Maria's strength and understanding of the technique let her convert Robin's size into a liability.
Nico RobinBlack Maria
07
Black Maria shifts from punching to confinement. She uses more webs and announces "Maria Cage!!" as strands cross the hall and lock Robin's giant limbs and body in place. The webbing forms a cage-like lattice around the battlefield while Black Maria peers in with satisfaction. She then reveals another danger: "By the way, my web is flammable." The surviving living weapon, the Wanyudo-like flame source, moves nearby with a "Fwoosh," making clear that Black Maria intends to burn Robin while she is trapped. The page turns restraint into execution. Robin is pinned by webs, her giant body is still transmitting pain, and Black Maria prepares to set the entire cage ablaze.

Black Maria ignites the trap with "Maria Kindling!" Flames roar up through the webbed hall. She recalls Robin's earlier confidence and says, "I seem to recall you saying this would be settled quickly!!" then twists the knife further: "This is what you get for defending that disgrace, Black Leg Sanji!! This humiliating defeat just proves how hopeless the pair of you are!" A translator note identifies "Gashadokuro" as a giant skeleton yokai. Black Maria keeps taunting, asking whether Robin will try blooming more limbs and whether a flower can survive in the sea of flames. Brook answers from below, "Black Maria-san, you keep saying moronic things... If I were you, I would make myself scarce!! Yohoho!!" He also suggests she ask her Gashadokuro friend to put out the fire.

Black Maria keeps insulting Robin as the fire and webs close in. She asks, "What are you going to do now, devil child?!" and repeats that Robin is "nothing but dead weight" for her crew. She says all the big shots know Robin is helpless and that the only thing of value about her is her mind: "You may as well not have limbs, no one needs your help!" The page cuts into Robin's memories of the Revolutionary Army. Koala describes a special palm strike, saying it is a move that helps in a pinch. Someone asks whether a slap would suffice, but Koala explains that if the opponent is going for the kill, it has to be a palm strike, and Robin needs to focus and strike with a "wham!" A translator note identifies Ryusoken as Dragon Claw Fist. Sabo offers to teach Robin Ryusoken instead, while Hack tells him not to pressure her because Robin is already plenty strong with all her dislocation techniques.

The flashback continues with the Revolutionary Army trying to help Robin gain an emergency finishing option. Koala says they want to help keep Robin safe after she leaves, and Sabo insists that he already said Robin is strong enough. Robin smiles and answers, "Haha... If that's how you feel, then why not? Go ahead and show me how to do this palm thing." Koala and Sabo cheer, "All right!" In the present, battered but focused, Robin thinks, "In retrospect, it's already come in handy a few times..." She forms "Gigantesco Mano!!" and remembers Koala's instruction: "You've gotta hone in on your opponent's core! This is going to be your trump card, Robin-san!!" Robin begins, "That's right... First you..." and uses "Mil Fleur: Fishman Karate..." to prepare the palm technique.

Robin completes the Fishman Karate lesson through her giant hand and strikes with "Giganteum!!" A massive palm erupts upward through the burning hall and smashes into the ceiling instead of Black Maria. Black Maria thinks Robin missed and starts to realize the truth too late: "You missed?! No, don't tell me...!" Debris and water crash down through the hall, dousing the flames and breaking the burning advantage Black Maria had built. Black Maria snarls, "You maggot!! You put out the fire," while Robin calmly answers from below. The page shows why the Revolutionary Army training mattered. Robin did not need the palm strike just to hit Black Maria; she used it with precision to erase the fire trap and create the opening for her true finishing form.

Robin unveils "Demonio Fleur!!" and takes on a dark, horned, winged giant form that terrifies Black Maria and the nearby enemies. Black Maria gasps, "A devil...?!" and Robin answers, "I'll be a devil if that's what it takes... to help the people... that count on me!!" Enemies scream, "Get away!! What the hell is that form?!" Black Maria tries to repeat her insult, saying Robin may as well not have limbs, but Robin cuts through it: "No!! I wasn't talking about me! You're the one who's helpless!!" Then Robin locks Black Maria into "Grand Jacuzzi Clutch!!" and twists the giant spider-woman's body with a brutal submission hold. Black Maria screams as the technique crushes her, and the page makes the chapter title literal: Robin embraces the demon image others project onto her if that is what it takes to protect her friends.

Black Maria's defeat echoes through the hall. Her subordinates ask, "What was that sound just now?!" and "And that haunting scream?!" Others wonder whether Black Maria-sama did something or whether the Gashadokuro is responsible, but ice and smoke block their view. When they finally see the dark giant shape, they panic: "Gyaah!! It's a demon!!" Brook uses their lineup to his advantage, saying, "Thanks for lining up like that. Yohoho! Now, without further ado! Phrase d'Armes... Orchestra!!" He slashes through the remaining enemies in a sweeping musical attack. Robin, exhausted after Demonio Fleur, says, "I overdid it a bit..." and Brook catches her with "Easy there, Robin-san!!" The page closes the duel with Robin victorious and Brook cleaning up the remaining night demons around her.

The scene shifts to Tokage Port in Udon, where Luffy devours a mountain of food supplied by Caribou. Caribou yells, "Don't you guys get it? That's a whole month's worth of food!! If you don't pay me back in full, I'll be screwed!!" He brags and complains at the same time, "Kehehehe-- My Swamp-Swamp Fruit's capacity is boundless!" while others marvel that he can carry so much food. Luffy eats rapidly, muttering through mouthfuls about Law, the crew, and Kaido. Nearby, the Heart Pirates ask for an update on Onigashima and wonder what happened to their captain and Bepo's group. The page shifts from Robin's victory to Luffy's recovery: the captain is refueling, and the allies at the port are trying to understand the state of the raid.

At Tokage Port, Momonosuke asks Shinobu for a drastic solution. Shinobu says, "I can do it, but... How can you ask that of me?!" and warns that Onigashima is too dangerous. Momo refuses to let Luffy go back alone, and Shinobu explains the cost: "If I do it, you'll never be able to return to normal, and you'll still have the heart and mind of a child!!" She also says the Flower Capital, and all of Wano, will be destroyed unless they act. Momonosuke does not waver. Crying but determined, he says he does not care and begs, "Please, your help could transform me into a bigger dragon!! I beg of you Shinobu! Use your Ripe-Ripe Jutsu... to make me an adult!!" The chapter ends with "Such unwavering resolve!!" and "Ch. 1021 / End," setting up Momo's sacrifice of his childhood for Wano's survival.
