Volume 5 Senku's Q&A Village Diet.png

Mecha Senku Q&A Search Question Corner

Question from, K.H.-san from Shizuoka Prefecture: "It sounds like Kohaku actually has eaten mice, but what do the villagers tend to eat in general? Do they grow crops?"

Answer from Mecha Senku: "Agricultural practices would not be very efficient in a community of this size, so they have developed neither the skills nor the technology!"

"The villagers are fundamentally hunters and gatherers. Above all else, they subsist on the abundance of fish that fill the surrounding lake!"

"How lucky! Is what we would say, except that this location was picked for just that reason."

"The old man named Sho is a particularly skilled fisherman, and the fish he catches feed the entire village! This allows others to focus on their own specialties, like Chrome with his exploring."
