This is basically what I came to say, having been a victim of this myself in my younger years
Deviations can definitely happen with justification, but I think it mostly is to the author's benefit to like... match the naming convention to the setting? Of course if you're creating an original race on a different planet or something you can make that up, but especially for comics located in real places... basically the above.
My personal example was in middle school I made this isekai-style story that started with the group of characters in a very typical north american style high school... but I also thought anime was really cool at the time, so I had a very north american looking cast of main characters with names like Raguna Takichiro, Arisa Sakura, and Tala Yumizuko. Ahh, that nostalgic cringe
