Thank you so much for the shout-out, @dunmeshistash !
To answer Anon's question, based on my research I believe the cultural coding of the characters is:
Northern and Eastern Continents: Mix of Germanic (dwarves) and Slavic (gnomes) as the dominant cultures, with historic influence from the West (elves), and recent immigration from the Eastern Archipelago (the far East)
Toudens: Saterland Frisian (North Sea Germanic) and Scandinavian.
Chilchuck and the half-foots: A mix of Irish and Jewish (European diaspora) as well as the dominant Germanic and Slavic cultures that surround them.
Senshi: This one is more complicated, since the dwarves are strongly coded as Germanic, but Senshi and Namari have names that are the phonetic spelling of Japanese words, as if they weren't Japanese. This is primarily a joke, and probably not meant to be taken very seriously - but it's also logically consistent with Kui's worldbuilding, as the dwarves are very close neighbors to the Japanese region on the Dungeon Meshi world map, so it would make sense that the dwarves have absorbed some Japanese culture (words, foods) into their own. So Senshi's cultural coding appears to be Germanic, with a bit of Japanese mixed in.
Anonymous didn't ask for the rest of the cast, but I'll give the short version here, for anyone that's interested:
Elves: Ancient Greco-Roman, West Asian, and South Asian, possibly a touch of the Americas and North Africa
Marcille: Italian and French
Izutsumi: She was raised in "Japan" (Wa island) by the local people, but is implied to have come from a neighboring large island with a Central or North Asian culture.
Kabru: Nepal, North India, Eastern West Asia
Rin: East Asian with a West Asian/North African influence
The Golden Kingdom: Germanic (Frankish)
Ogres: Central and North Asia/Eastern Eurasia
Orcs: They have bits of all the other cultures in theirs. Some of the names may come from several different aboriginal groups.
Kobolds: Based on clothing and geography, North Africa, West Asia, South Asia. Kuro's real name and nickname are both Japanese, but like Senshi and Namari, these are jokes and probably not meant to be taken seriously.
Please keep in mind that this is of course only my opinion, but it's based on quite a bit of research and fact-checking. Hope this is helpful to someone!
