One Piece Chapter 686: The Yuki-Onna of the Biscuit Room

The chapter opens in the laboratory, B-Block, third floor, "The Biscuit Room." Broken structures and drifting snow fill the room as Monet attacks the Straw Hats and the children. She lunges with her harpy-like body, and Zoro intercepts her in a violent clash of blades and talons. The impact explodes across the panel while Robin is thrown back. Nami cries, "ROBIN!! ARE YOU ALRIGHT!?" Robin, bleeding but composed, answers, "Nnn... It's just a scratch...!!" The situation remains urgent because the children are still moving after Mocha and the candy. Someone calls, "Let's hurry and stop those children...!!" The page establishes the immediate battlefield: Zoro is holding Monet back, Robin is injured but mobile, and the rest must reach the children before the candy makes the experiment worse.

Mocha runs through the Biscuit Room with the giant candy while the other children chase her through the snow and debris. Chopper calls out in panic, "NAMI!! PLEASE HURRY!!" because "THE CHILDREN ARE LEAVING THE ROOM!!" Nami realizes what this means and says, "I promised that I would stop them... but I haven't been able to." Chopper adds the immediate consequence: "AND NOW MOCHYA'S IN TROUBLE!!" Mocha, panting hard with "HAA" after "HAA," keeps moving while the children close in behind her. They shout, "STOP!!" "WAIT, MOCHYA!!" and one child demands, "HAND OVER THAT CANDY!!" The page centers Mocha's burden: she is still only a child herself, but she is carrying the dangerous candy away from the others while adults and allies struggle to catch up.

Mocha knows she cannot keep running forever. She gasps, "I can't do that...!! Haa haa," while thinking back to why the candy matters. She says, "I asked Chopper-chan just what kind of candy this is...!!" Chopper's warning echoes over the chase: "We mustn't eat it!!" and Mocha begs the others, "Please! Go back to the way you were!!" But the children are still under the drug's craving and yell, "Hand it over, Mochya!!" The memory becomes clearer: Chopper tells her, "If we pass it on to a grownup, that grownup would die..." and another child cries, "Wahhh... wahhh... Mochya... this is just how it is. We're sick." Then a gentle promise from the past cuts through the fear: "Wouldn't it be a lot worse if your mom or dad died? We'll get treatment and be all cured within a year." Mocha is running not only from the children, but from the false hope that kept them obedient.

Mocha remembers how Caesar manipulated the children with kindness. Caesar once declared, "It's my honor to have you as my first generation of patients," then confessed through tears, "The truth is... I once... I lost my own son to this sickness. But never again!! I don't ever want to see another child suffer like that...!!" He sobbed, "Nor do I want to see any sad parents who've lost their own children...!!" The children reacted with sympathy, "Ohh," and he pretended embarrassment: "Ahh, I'm sorry. This is embarrassing... I'm getting all teary-eyed..." When they asked, "Mr. Master, are you alright?" he continued smiling while Monet introduced "children with the same sickness who've come from other islands." The children introduced themselves too: "I'm Uzu!! Nice to meetchya," "My name is Doran," and "The name's Konbu!" Back in the present, those same children scream, "CANDY!!" and "GIVE US THE CANDY!!!" while Mocha shouts, "STOP RIGHT THERE, MOCHYA!!" The page reveals the cruelty behind their loyalty: the children's trust was built on Caesar's deliberate lies.

The memory continues with Monet welcoming the children into the routine of the facility. She says, "Some new friends have come to join us today," and tells them, "Now everyone play nice. And if you need anything, just let me know." The children answer, "Okay, Ms. Monet." Mocha now understands the entire kindness was false. She thinks, "Even the kindly Ms. Monet was in on it...!!" and then, with the betrayal fully clear, "It was all a lie." The old promise of treatment is exposed as part of Caesar's experiment when Monet says, "You've been working so hard with your treatment, so here's a treat. Yes, it's candy from Master." In the present, Mocha keeps running and cries, "Let's all run away from here!!!" and "Please go back to normal!!" The children chase her through the hall, still hungry for candy, but Mocha's goal has shifted from obedience to rescue. She wants to save the same friends who are now trying to take the drug from her.

Nami, Robin, and Chopper pursue the fleeing children through the Biscuit Room. Nami orders, "AFTER THEM, QUICKLY!!" and Robin adds, "AS FAST AS YOU CAN!!" Chopper rides along with them, worried and frantic, while the room remains full of snow and chaos. Behind them, Zoro faces Monet. He breathes heavily, "Nnn hhhhhh hhh," and then Monet suddenly dives away from him toward the others. Zoro realizes the danger and snaps, "YOU BITCH!! WHAT DO YOU THINK YOU'RE DOING!!" Nami sees Monet coming and yells, "EH!? WHAT WHAT WHAT!? HOLD UP!! WHY'RE YOU COMING THIS WAY!?" Chopper panics, "GYAH!! WAIT, NAMI!! YOU CAN'T USE ME AS A SHIELD!! YOU CAN'T!" Monet's movement makes the battlefield unstable: Zoro can block her, but if she slips past him, the weaker allies and the children become the targets.

Monet closes in on Nami and Chopper, but Zoro cuts back into the fight. The clash erupts with blades, wings, and talons colliding, while Nami screams, "KYAH HHHHH HAH." Monet examines Zoro's behavior and says, "What a pity." Zoro answers angrily, "How dare you aim for the weaker ones!!" Monet spins through the snow with "SPIN SPIN," testing him more than simply attacking. The page is important because Monet starts to notice a pattern: Zoro keeps stopping her, but his attacks do not cut her down with the force he should be able to use. His anger is real, yet he is still fighting in a guarded way. That hesitation gives Monet room to think she can exploit his reluctance and keep pursuing Nami, Chopper, and the children.

Nami decides to strike back. She warns, "WATCH OUT NOW," and uses "HEAT EGG!!" The heat bursts against Monet's snow body, making Monet cry, "GYAH HHHHH HH!!" Nami is surprised and relieved: "Well of course--using heat really works!!" Then she remembers Monet's bounty identity: "'CAT BURGLAR' 16 million berries..." Monet sinks into the snow and vanishes. Nami orders, "SO STOP FOLLOWING US, OK!!" but almost immediately realizes the danger is not over. She shouts, "UHH!! NOT AGAIN!! SHE DOVE INTO THE SNOW...!!" Chopper, watching Monet disappear into the white floor, asks, "DO YOU EVEN WANNA FIGHT!? HUH, YUKI-ONNA!!" The page shows that Nami can hurt Monet with heat, but Monet's Snow-Snow Fruit lets her avoid a clean defeat by merging into the room's snow.

Monet seals off the escape route. Nami sees the doorway covered and cries, "EHH!?" then shouts, "THE EXIT...!!" Monet announces the technique: "SNOW FENCE!!" The snow piles into a barrier and someone realizes, "SHE GOT US...!!" Monet follows by unleashing "10,000 YEAR SNOW," filling the room with a freezing storm. Robin calls, "NAMI!?" and Nami shouts, "WAH!!" as the cold slaps across her and Chopper. Chopper suffers under the snow and gasps, "UOOH HH!!" while Nami cries, "AH!! THE SNOW!!" The cold hits hard enough that someone says, "SO COLD!! I CAN'T MOVE!!" Monet's strategy becomes clear: she is not merely attacking one person. She is changing the room itself into a prison, stopping the evacuation and using the cold to immobilize the weaker crew members.

Monet emerges in a monstrous snow form, jaws wide and body swollen by the storm. Nami and Chopper are caught near her as she roars, and someone screams, "GIIYAHHH HH!!!" Zoro sees Monet move again and says, "NOT AGAIN. NOW SHE'S OVER THERE!!!" Monet declares, "I WON'T LET YOU FOLLOW THOSE CHILDREN...!!" Her resolve is focused on protecting Caesar's experiment, not the children themselves. Nami sees the next strike coming and cries, "LOOK OUT, CHOPPER!!" Monet attacks with a huge bite and another freezing surge, making Chopper yell, "FUO OHHH HH!!" The scene keeps the danger concrete: every moment Monet delays them gives the drugged children more time to catch Mocha and gives Shinokuni more time to advance through B-Block.

Robin intervenes with her ability and calls, "'Quatro Mano'." Multiple arms appear around Monet and clamp down with a sharp "SPANK!!" The blow catches Monet and breaks the pressure around Nami and Chopper, scattering snow and debris across the room. Chopper and Nami are thrown down but alive. Chopper lands with an "OWW," while Nami admits, "Wh... whoa... that was scary!!" Monet, however, is not meaningfully stopped. She twists and gathers herself again, her mouth and wings still formed from snow. Robin's move buys a moment, but the page shows the limitation of their position: without Haki or the right elemental counter at the exact moment, even a clean hit only disrupts Monet's Logia body rather than ending the fight.

Monet states her duty plainly. Watching the children move away, she says, "...This just won't do... Those children are Master's precious experiments..." Then she adds, "My duty is... to protect Caesar and his experiments..." Chopper is furious and demands, "Who was it who planted in Mochya the idea to rebel?" He rejects Monet's claim and shouts, "What are you talking about!? The children asked of their own free will to be saved." Zoro cuts through the hesitation and orders, "OUT OF THE WAY, YOU GUYS!!" Then he turns to the others and says, "Well, follow them!!" The visual action matches the words: Zoro strikes into Monet's snow barrier and opens the path while the others run after Mocha and the children. The argument is also a moral split. Monet sees the children as Caesar's property; Chopper insists their wish to be saved is real.

Nami, Robin, and Chopper rush on. Nami shouts, "LET'S HURRY!!" Robin answers, "OK!!" and someone calls, "JUST HANG IN THERE, MOCHYA!!" As they leave, Monet speaks with bitter contempt. She says, "What a coarse bunch, day after day. I've treated those children with nothing but kindness and given them a life in which they want for nothing." Then she accuses the Straw Hats: "But of course pirates would try to steal such 'precious treasures' from the parents that care for them!!" Zoro tests her logic with a calm question: "ALL RIGHT. SO THERE'S REALLY NO PROBLEM, THEN?" Monet answers with another snow technique, "TABIRA SNOW," and says, "DON'T GET IN THE WAY OF MY DUTY!!" The page shows how deep Monet's loyalty to Caesar runs. She dresses exploitation up as care and sees rescue as theft.

Zoro finally presses Monet more seriously. Monet attacks with "SKIN KATANA!!" but Zoro blocks and watches her closely. He starts, "This whole time, you've..." Monet, seeing that he still has not cut her down, asks, "Why've you only been blocking my attacks and not striking back with your blades...!?" Zoro says nothing at first. Monet licks her lips and concludes, "To be completely honest, I didn't really think I could win against you... But now... I unexpectedly wonder if that might not be the case?" Meanwhile, the others have moved on through the cold Biscuit Room. Zoro tells them, "MARINES!! Let's head in that door!!" and adds, "So everyone's out to steal the children... I can't forgive any of you." The page sets up the standoff: Monet believes Zoro's reluctance gives her a chance, while Zoro's silence suggests he has been holding back by choice rather than weakness.

The G-5 Marines finally reach the Biscuit Room area in a roaring charge. Sanji and the Marines burst forward shouting, "CHARGE!!" while Zoro stands in the lead. Sanji yells, "WHY ARE YOU IN THE LEAD!!" and the Marines are immediately relieved that the children are not there, shouting, "BIG BRO!! THE KIDS AREN'T HERE BUT THAT'S 'PIRATE HUNTER ZORO'!!" Another Marine warns, "That guy is a real brazen bastard," but others answer, "ALL RIGHT, YOU GUYS!!" The Marines begin heckling Zoro: "PULL OUT YOUR LOWER LIPS AND MOCK HIM!!" with a chorus of "YEEE EEE!!" Zoro, unimpressed, says, "Although it would be nice if they all slipped, cracked their heads, and died..." Sanji learns the direction from Monet, who says, "If it's Nami and Robin you want, they went that way. You're in my way, so get out of here." Sanji answers, "Oh ho ho we got some good information from this shitty moron. Okay, let's go, you bastards!"

Sanji's group starts to move on, but the Marines cannot stop reacting to Monet. Sanji snaps, "STOP SPACING OUT, YOU NOISY IDIOTS!! HURRY UP AND MOVE ON AHEAD!!" The Marines protest, "UOHHH YOU'RE RIGHT! SHE'S CUTE," and one says, "IS WHAT I WOULD BE THINKING, BUT THERE'S A BEAUTIFUL LADY BACK THERE!!" Another notices the truth too late: "BUT WAIT, LOOK! SHE'S NOT HUMAN!!" and another cries, "SHE'S A 'HARPY'!!" Even that does not end the distraction. They shout, "BUT SHE'S STILL A CUTIE IN SPITE OF THAT," "WHAT BEWITCHING APPEAL!!" "DEFINITELY SEXY," and "WHAT THE HELL! ARE YOU REALLY THAT WEAK TO SUCH COMPLIMENTS!!" Monet, meanwhile, hears their crude admiration while something shifts in the snow. She asks, "Wha...!! What is she..." Then her anger returns: "ANYONE WHO WOULD TRY TO TAKE AWAY MY CHILDREN... I WON'T FORGIVE!!" G-5's arrival adds noise, but Monet's target remains the same: stopping anyone who threatens Caesar's control over the children.

Monet launches herself into a terrifying attack. The snow swells around her into a huge predatory shape, and the Marines panic. One cries, "MY... MY SHOULDER!! WHAT'S GOING ON!!?" as ice and snow crack around him with "CRACK." Monet's monstrous form snaps forward, making someone scream, "GYAH HHHH HH!!!" while she laughs, "HEE EEEE EE!!" The Marines realize what they are facing. Someone shouts, "THIS... THIS THING!!" and another says, "SHE'S A LOGIA!!" In the lower panels, Monet bites and tears through the confusion while G-5 keep reacting with "MUNCH!" "MUNCH!" "SHINK," and "KYAH HHHHH HAH!!" Zoro watches the attack and understands that ordinary panic will not work here. Monet is not only a harpy with claws; she is a Logia whose snow body can become a weaponized monster.

Tashigi arrives at the Biscuit Room with Marines behind her, sword drawn and coat flaring in the snow. The Marines cheer, "UOHH HHHH HH!!" and call, "CAPTAIN-CHAN!!" while another voice recognizes her as "A SWORDSWOMAN WHO CAN USE HAKI...!!" Her arrival changes the balance because she can actually strike a Logia. A Marine reports, "WE'VE STOPPED THE GAS FROM COMING INTO THIS ROOM, AT LEAST FOR THE MOMENT." Tashigi judges the situation and says, "BUT THERE'S NO GUARANTEE THAT IT WON'T SEEP IN FROM SOMEWHERE ELSE." She orders, "THERE'S NO TIME, EVERYONE. PLEASE CHASE AFTER THE CHILDREN WITH EVERYTHING YOU'VE GOT!" A Marine hesitates, "B... BUT WHAT ABOUT YOU, CAPTAIN-CHAN!?" Tashigi answers, "I WILL REMAIN!" Then she looks at Zoro and says, "IT SEEMS... THAT I AM NEEDED HERE!" Zoro reacts, "HUH!?" The chapter ends with Tashigi stepping into the Monet fight while the rescue effort continues after Mocha and the children.
