It seemed to me that Zoro's sense of direction has gotten worse over the series, and I think a lot of people, like me, believe he has a backstory in Wano Country, so I decided to put those two things together. I hope you like it!

"Did that street just move?" Usopp asked incredulously. Despite his insistence that he had caught I-can't-go-on-this-sword-filled-island Disease, Usopp was walking along the streets of Wano Country's capital in disguise, entirely unprepared them for this.

"Of course it did," Zoro replied, unhesitatingly taking the lead.

"Oi! You can't lead, Zoro! We need to get to the meeting point with Law and Kinemon today!" Usopp objected, speeding up so he was beside their errant swordsman. Zoro stiffened, affronted, but Franky spoke before he could.

"Well, I've never seen streets move before today, but I'd love to know how they do it."

"I'd be fascinated to discover the historical reasons for such an innovation," Robin mused, looking around wonderingly.

"How else are you supposed to get anywhere?" Zoro questioned, making everyone present sweatdrop.

"Moving streets really aren't normal, Zoro," Usopp told him seriously. "Wait! Is this why you're always getting lost?!" Zoro frowned at him.

"It's not my fault other countries don't have controls on every corner, Usopp. How the hell am I supposed to tell the roads which way to go? The people in charge should learn to do their jobs." The green haired swordsman sounded truly indignant and Usopp felt his brain melt just a little.

"You seem familiar with the country, Zoro," Robin speculated, before Usopp could comment on the swordsman's entirely preposterous remark. How many years has Zoro lived away from this island believing that he roads actually moved? Zoro nodded to Robin.

"Yeah, I was born here," he told them, not realizing that all of them, excluding Robin, had frozen in shock.

"You were born here? How the hell did you end up in the East Blue?" Usopp sputtered.

"My dad took me traveling to learn swordsmanship," Zoro told them casually, walking up to some controls on a wall and punching something in, "but one day he and I had a big fight and he told me not to bother coming back until I could beat him. So I stayed on the island and kept training." Before Usop could reply - and there were a lot of things that needed saying after that explanation - the ground beneath their feet started to move. Usopp did not squeal, no matter what anyone may have said later, but Franky got on his hands and knees to better inspect the mechanisms.

"Franky," Usopp whispered, because being with team No Common Sense had sounded good when Luffy was heading to face off with Big Mom, but evidently had it drawbacks, "I don't think crawling around inspecting the ground is very inconspicuous."

"What do you know about the system, Zoro?" Robin asked with appalling calm.

"It's for invasions," the swordsman answered with a shrug. "You can control where the road goes at each corner, but that can be overwritten by the royal family in case of emergencies."

"So an invading army would have serious difficulty reaching the palace, which would give the defenders an advantage."

"This is a closed country," Zoro commented. "There are a lot of things in place to defend the people."

"Does it get attacked often?"

"Sometimes," Zoro commented. "I know the World Government tried to subdue it, but I was pretty young for that. You might see areas where they are still rebuilding."

"Wano country fought off the Wolrd Government?!" Usopp exclaimed, making Zoro frown.

"I was told it was more like the World Government decided conquering the country was more effort than it was worth and choosing to leave."

"Still, that's pretty amazing," Usopp praised. Zoro, being Zoro, just shrugged.
