Installment 686 of One Piece keeps the Biscuits Room clash alive as Zoro shields his crew from Monet while Mocha begs her drugged friends to stop. The snow harpy seals the exit, transforms, and is driven off, only for Sanji, Tashigi, and the G-5 squad to storm in.
Inside the lab's third floor, the duel between Zoro and Monet drags on while Robin reassures a worried Nami and Chopper that the wound she took is nothing serious. Their attention stays fixed on the rampaging youngsters, who keep chasing Mocha for the candy she carries. As she sprints, Mocha relives how Caesar lured her in with a sob story about a lost son, how the kindly children Uzu, Doran, and Konbu welcomed her, and how Monet's sweetness masked a lie. Realizing the whole thing was staged, she pleads with the others to wake up.
Monet lunges at Nami, but Zoro turns aside the blow, scolding her for hunting people without weapons. Nami answers with a Heat Ball that scorches the harpy's wing. Trapped behind a wall of snow, the crew watches Monet rear up as a grotesque ice demon and snap at Chopper. Robin pins her with the Hana Hana powers, Zoro carves an opening, and the three slip out to pursue the children. Monet notes that her opponent never once swung in earnest.
Several of the captive children gain names, among them Sind, Doran, Uzu, and Konbu. Once the youngsters bolt from the room after Mocha, Nami, Chopper, and Robin give chase while Zoro lingers to keep Monet occupied. Soon afterward Sanji arrives with Tashigi and the G-5 Marines, who briefly gush over Monet's looks before she sheds the pretense and bites into one of them.
Gunfire does nothing against a Logia body, so Tashigi steps forward and lands a Haki-charged cut that wounds the harpy. The Marines block the doorway to keep the deadly gas out, then prepare to rescue the children. Tashigi, however, refuses to leave, declaring that she alone will hold the line against Monet.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

When I first decided to commit to watching One Piece seriously, I knew I was embarking on one of anime's longest and most beloved series. With over 100...
The chapter title nods to Monet's snow-woman form. Its cover continues the Caribou serial with Coribou freeing his captured brother. The G-5 unit succeeds in stopping the poisonous H2S gas from breaching the Biscuits Room. Caesar appears only within Mocha's flashback, which fills in how the children were recruited and deceived.
The snow girl featured in Chapter 686, "The Snow Woman in the Biscuits Room," is Monet, a Devil Fruit user who fights the Straw Hats in a harpy-like snow form while guarding Caesar Clown's captive children.
In Chapter 686, Monet's Devil Fruit lets her control and become snow and ice, giving her a Logia body that regular gunfire cannot harm, until Tashigi lands a Haki-charged cut that wounds her.
Monet lunges at Nami in Chapter 686, but Zoro turns aside the blow and Nami answers with a new technique called Heat Ball that scorches Monet's wing.
Because gunfire does nothing against Monet's Logia body, Tashigi steps forward in Chapter 686 and lands a Haki-charged cut that finally wounds the harpy.
While fleeing the drugged children in Chapter 686, Mocha relives how Caesar Clown lured her in with a sob story about a lost son and how the other children's kindness masked the deception, prompting her to plead with them to wake up.
