Set during chapter 310, during the Davy Back Fight.
Pirate Hunter Roronoa Zoro dumps his three swords into the Foxy crew member's arms and turns away without a backward glance, already bickering with his team mate. The Foxy Pirates steal looks at each other and quietly snigger; in the midst of the game and its excitement, it won't be difficult to 'accidentally' misplace a notorious swordsman's swords for it to later appear somewhere else like, for example, a black market. The Foxy pirate pulls the three swords closer to his chest and carefully moves back-
"That's Zoro's," a voice calls out and for all the cheerfulness, it makes him freeze mid-step. The Straw Hat captain, who is watching him with a tilted head, continues. "Those are important to Zoro."
It is strange how despite the enthusiastic commentary and the crowd's cheering, the quiet warning reaches him loud and clear.
"That means those are important to us too 'kay?"
Slowly, the Foxy pirate nods and doesn't find it in him to breathe again until Monkey D. Luffy turns away.
