@Himada4 the thing about la li lu le lo on the keyboard is just for making small characters (little hence the "l") but in katakana ra and la are the same soundwise, and are often portrayed as such much like in "ラブ" or in "ラッキー" or in ”ルーザー” or in many other words lol, this isnt something you can argue about its just how it works. The whole "translations as an aid to studying japanese" argument thing is one of the most annoying things to me personally, i mean theres a reason we make jokes about memes like the infamous "keikaku means plan". If someone wants to learn japanese they should study japanese, not read manga translations xD. Honestly it feels like u kinda butchered the name, its pretty clear it should be Helan or Hellen (which in some cases CAN be pronounced more like ヘラン) while i appreciate that you are translating this, my point is that i believe your goal is to accurately and effectively translate the manga, not give us romaji. Translation isn't about being literal, or we would be stuck with very confusing grammar, so i personally believe that a translator should take a moment with katakana names to find what is the BEST interpretation, not the easiest.
im not trying to be mean or obnoxious but i AM kind of baffled by why you think that it matters to the readers whether you always give the direct romaji considering that many people who read this will probably never see the raws or have any idea of what you are talking about. My advice as a fellow translator would be to pick the answer that you think best fits the theme and mood of the manga, and as in this case this is clearly a western themed manga about a western character doing western things, a western name for the area is a better choice than one which doesnt mean anything at all.
Edit: Also who would you be confusing? i dont understand that part. are you assuming that your readers also have read the raws? if anything changing the names of characters after the previous scanlation group had picked a name is far more confusing than anything else, and should only happen if you have a very good reason
