I feel like the name "Eutrope" (ユトロープ, Yutoropu) might be a mis-romanisation? It just doesn't look quite right for Hhetsaro names we've seen so far.

I would suspect it might be supposed to start with the double-Y used for several other names in the region, but the existing ones are all Shetona so it comes back to figuring out whether they have a shared or separate language.
