Quote:Power lines arn't just seen in Leaf, they also show up regurally throughout the Tsunade retrieval arc.
Leaf is as was said a large population center... at least two rich families live(d) there. Rich people. Rich people like snazzy new stuff you peons can't afford. Like none burning lights.
Quote:Yes. Again look throughout the Tsunade arc. There's writing all over the place. If it was just in Leaf I'd be more dubious about how widespread literacy is.
While I can believe in a merchant tongue (good for business if you can keep records) I'm still dubious about its commonality among the random civilians in that world. Now it may be a matter of getting a good wide shot of the Hidden leaf and labeling each building or cluster there of, but they don't exactly fixate on the life of your random villager much. Those that do get fixated on are well off for the area.
