The chapter file opens with a Weekly Shonen Jump cover featuring One Piece promotional art alongside other magazine series. Luffy appears in the corner of the cover, while the page itself is publication material rather than a story page. It is useful as attached release context, but it does not advance the Whole Cake Island plot.

Chapter 881 is titled "A Wave Room." The cover story continues: "DROPPING IN ON THE LIVES OF THE STRAW HAT GRAND PIRATE FLEET, VOL. 15, SAI ARC 'DON SAI AND BABY 5'S WEDDING.'" The scene shows Sai and Baby 5 in wedding clothes while others celebrate around them, marking the resolution of Sai's cover-story thread after the broken engagement fallout.

In the mirror world, Luffy refuses to accept the Sunny's despair. Battered and furious, he shouts, "WHAT THE HELL DO YOU MEAN 'WE'RE DONE FOR'?!" and "WHAT'S GOING ON OVER THERE?!" At sea, the Thousand Sunny is tiny beneath the wall of water Big Mom has created, and the crew calls back, "OI! GUYS!" The situation is worse than before because they cannot simply fly away. Someone says, "IF THAT THING SWALLOWS US UP, WE'RE DONE FOR!" and another adds, "YEAH! COUP DE BURST? NOW!" But Brook and the others realize the problem: "WE CAN'T! WE DON'T HAVE ENOUGH COLA!" Nami apologizes through the panic, "PEDRO... I'M SO SORRY! AFTER ALL YOU DID TO KEEP US ALIVE..."

Perospero tries to stop Big Mom from destroying the very cake she wants. Riding with her across the sea, he yells, "WAIT WAIT WAIT! STOP!" and warns, "HOLD ON A MINUTE, MAMA! AT THIS RATE, YOU'RE GONNA SINK THE CAKE, TOO!" Big Mom ignores him and keeps roaring for the wedding cake, "WEDDDIIIIIING" and "CAAA AAAAA AAA," while the chase continues. Perospero calls after her, "MAMA!" as the Sunny's crew scrambles in the distance with "HURRY!" and "OKAY!" Big Mom's eyes are wild and fixed only on hunger. Even her own son cannot reason with her, because the cake matters only as an object of obsession, not as something that must survive the pursuit.

Jinbe takes the helm under impossible conditions. The crew rigs a sail and asks, "I-IS THIS GOOD?!" while someone calls, "JINBE!" Jinbe answers, "YANK," then Nami asks, "NAMI! WHERE'S THE WIND?!" She points out the coming weather: "A STRONG WIND SHOULD COME FROM THE SOUTH, SOON!" Chopper is alarmed by the scale of the maneuver and asks, "WHAT ARE YOU TRYING TO DO, JINBE?!" Jinbe explains the plan: "HIGH-SPEED TACKING!" Nami panics, "WHAT?! YOU'RE GOING TO STEER THIS SHIP?!" Jinbe's answer is decisive: "WE'RE GOING TO THE GREEN ROOM!" The page shifts from despair to seamanship: the Sunny cannot outrun the wave, so Jinbe intends to ride through it with timing and control.

The crew briefly thinks Jinbe is turning them back toward death. Someone yells, "THE HELL IS THAT?! WHY ARE YOU TURNING US BACK TOWARDS THE WAVE, JINBE?!" Brook suddenly understands and cries, "I GET IT NOW! THE 'GREEN ROOM' IS HEAVEN, RIGHT?!" Chopper wails, "DOCTOOOOOR! LOOKS LIKE I'M FINALLY COMING FOR YOU!" Jinbe gives the only order that matters: "HOLD FAST TO THE SHIP!" The crew still doubts him, shouting, "IT'S OVER..." and "THERE'S NO WAY... YOU CAN'T SURF THIS THING!" But Jinbe holds the helm as the wave crashes down, and the Sunny is swallowed into the white water with a huge roar. The maneuver has begun, and survival now depends on Jinbe's control inside the wave.

Inside the wave, the Sunny enters the Green Room. The crew realizes they are not crushed but carried within a hollow space in the breaking water. Chopper cries, "WE'RE INSIDE THE WAVE?!" and Jinbe explains the phenomenon: "THE 'GREEN ROOM' IS THE SHORT-LIVED SPACE MADE INSIDE THE CREST OF A BREAKING WAVE. A WAVE ROOM! FISHMAN CHILDREN LOVE PLAYING IN IT." Nami, astonished, says, "SO THIS IS THE OTHER SIDE, HUH... IT'S PRETTY..." The ship rides through the curling tunnel, and Jinbe praises them: "WE'VE GOT A FINE SHIP AND A FINE NAVIGATOR. WITH THE RIGHT STEERING, THIS SHIP'S INVINCIBLE!" The Sunny begins to emerge, with the crew shouting, "WE'RE COMING OUT NOW! HOLD ON!"

The crew survives the wave. Nami realizes what Jinbe has done and says, "HE'S CONTROLLING THIS SLOOP LIKE IT'S JUST AN EXTENSION OF HIMSELF! AMA-ZING..." Chopper asks, "SO WE'RE NOT DYING?!" and praises him, "YOU'RE SO COOL, JINBE!" The Sunny shoots out of the wave's tunnel while Big Mom and Perospero remain behind. Perospero laughs off the attempt, "KUKU-KU... WAHAHA! WELL, WHATEVER." Big Mom is still lost in the same demand, crying, "WEEEDDIIING." Perospero turns the chase back into contempt and shouts, "EAT THIS, YOU ANTS!" The crew has survived absolute disaster, but Big Mom's side still refuses to let the ship escape.
In the mirror world, Perospero contacts Katakuri and declares victory too soon. He calls, "PEROSPERO HERE!" and says, "OI, KATAKURI! WE'RE DONE OVER HERE!" Luffy, listening from the mirror side, panics, "OI, NAMI! BROOK?! CARROT?!" Perospero says, "NO NEED! SADLY, THEIR SHIP HAS SUNK TO THE BOTTOM OF THE OCEAN. OH, DEAR... WE WERE JUST ABOUT TO INVADE THE SHIP, TOO!" But the mirror does not show water on the other side. A Charlotte soldier notices, "WHA-?! THAT'S STRANGE, SISTER. THE OTHER SIDE OF THIS MIRROR DOESN'T LOOK LIKE IT'S UNDERWATER." Then the mirror breaks with a crash, and Brulee cries, "SISTER! THE MIRROR, IT JUST..." Katakuri watches in silence, realizing the claim of victory is uncertain.

On the Sunny, Nami breaks the mirror link despite the pain of cutting off Luffy. Brook cries, "NAMI! THE MIRROR! WHY'D YOU-" and Chopper realizes, "NAMI! LUFFY CAN'T COME BACK HERE ANYMORE!" Nami is firm: "LISTEN UP. BREAK THEM ALL. ALL THE MIRRORS ON BOARD." Chopper asks, "ARE YOU TRYING TO INTERFERE WITH LUFFY?!" Nami answers with the authority Luffy gave her: "THOSE WERE THE CAPTAIN'S ORDERS!" She adds, "LET ME FOCUS ON THIS GUY," meaning Luffy needs them to stop worrying about his return and let him fight Katakuri. Her final order is urgent: "HURRY!" The crew must preserve the ship by obeying Luffy, even though it closes his way back.

The mirror world reacts as the Sunny's mirrors shatter one after another. Luffy breathes hard while the fragments crash around him. A soldier says, "LOOK. ALL THE MIRRORS TO THE SHIP ARE BREAKING." Another guesses, "MAYBE THEY'RE STILL ALIVE? WEIRD..." and Brulee laughs, "BECAUSE THE SHIP SUNK, THE MIRRORS ARE PROBABLY BREAKING DUE TO THE WATER PRESSURE! AHAHAHA!" Luffy, however, knows what really happened. He calls into a remaining connection, "OI! LUFFY! I NEED TO TALK TO YOU. GET AWAY FROM THE OTHERS." Then the Straw Hats answer from the ship. Chopper asks, "ARE YOU GUYS OKAY?!" and Luffy says, "OI! STRAW HATS..." The crew responds, "EVERY-ONE'S OKAY, LUFFY."
The crew reports their survival and plan to Luffy. Brook tells him, "LUFFY! WE BROKE ALL THE MIRRORS ON BOARD!" Chopper adds, "WE THOUGHT WE WERE GONNA SINK, TOO! BUT JINBE DID SOMETHING CRAZY!" and Brook says, "THAT CANDY GUY SAID THAT THE SUNNY SANK!" Luffy answers, "OKAY! I'M GLAD!" Nami then makes the cost explicit: "NOW, NO ENEMIES CAN COME BOTHER US HERE, BUT YOU WON'T BE ABLE TO GET BACK, EITHER!" Luffy, still smiling through exhaustion, says, "YEAH. THAT'S FINE! I'LL BE OKA-" but Nami cuts him off: "NO YOU WON'T! YOU DON'T EVEN HAVE ANY PLANS, DO YOU?! LISTEN CLOSELY, LUFFY!" She lays out the schedule: "SANJI'S MAKING THE CAKE ON CACAO ISLAND RIGHT NOW. WE'RE HEADING OVER THERE TO MEET UP WITH HIM. WE SHOULD MEET UP WITH HIM IN 10 HOURS AT THE EARLIEST. AROUND 1 IN THE MORNING."

Nami gives Luffy his rendezvous condition. She says, "UNDERSTAND? AFTER YOU BEAT UP THAT GUY, FIND A MIRROR THAT CAN TAKE YOU TO CACAO ISLAND! WE'LL MEET UP THERE, OKAY?" Luffy answers around the food in his mouth with a slurp, but Katakuri does not let him rest. Nami calls, "LUFFY!" as Katakuri kicks Luffy with a crushing strike. The blow smashes him away from the mirror, and the crew hears the impact. Luffy's plan is now fixed: beat Katakuri, find a mirror to Cacao Island, and rejoin the crew at the planned meeting point. Katakuri's attack immediately reminds him how difficult that route will be.

The connection breaks into panic as Katakuri attacks again. Chopper asks, "LUFFY? WHAT HAPPENED?" while Luffy coughs, "GUH-" and the broken mirror falls away. Katakuri keeps up the pressure, throwing Luffy across the mirror world and forcing him back into the fight. Nami, Chopper, and Carrot can only watch the fragments and listen to the failing connection. The page is mostly action, but its meaning is direct: Luffy has heard the rendezvous plan, yet he must now survive Katakuri long enough to use it. The crew can no longer pull him back, and the last safe bridge between ship and captain is gone.

Katakuri escalates with "WILLOW MOCHI!" A note explains it is a type of mochi named after the willow tree, not made from it. His mochi limbs whip and hammer Luffy from multiple angles, slamming him into the floor and walls of the mirror world. Luffy tries to move through the blows, but the barrage is relentless. The page is a sequence of impacts: Katakuri's attacks stretch, curve, and crash down with enough force to pin Luffy under the pressure. By the end, Luffy is on the floor again, still conscious but clearly being overwhelmed by Katakuri's reach, speed, and prediction.

Luffy and Katakuri face each other in silence for a moment, both dripping and battered. Katakuri watches him with a grin, while Luffy returns the look with his own bloodied smile. Out at sea, the Sunny continues across the rough water. Nami urges the others, "HURRY UP ALREADY GUYS!" and Luffy, aware that he has to last until the crew can reach Cacao Island, says, "COME ON! I'M GONNA DROP DEAD WAITING HERE!" The page links the two fronts: Luffy must endure the mirror-world duel, while the crew must keep the Sunny alive and move fast enough to make the promised rendezvous possible.

The crew answers from the Sunny with determination. They call back, "YEAH!" and someone says, "LATER, OKAY?" while Nami, Chopper, Brook, and the others push the ship onward. In the mirror world, Katakuri hears Luffy's line and asks, "ARE YOU SURE YOU WANT THOSE TO BE YOUR LAST WORDS?" Luffy, breathing hard but grinning, says, "I AIN'T PLANNING ON DYING HERE." Katakuri repeats, "IS WHAT YOU WILL SAY, BUT..." and Luffy cuts through the fatal framing with a stronger declaration: "I AIN'T PLANNING ON DYING HERE!" The chapter ends on "CAPTAIN LUFFY'S DETERMINATION!" and a stare-down with Katakuri, with the note that One Piece will be on break next week.
