Believe me, I've spent a lot of time thinking about what the best course of action would be. After the initial backlash, I was devastated, because I personally felt that I'd given a good and faithful rendition of how Nanami appears in Japanese, to English speakers; she has a very heavy accent that contrasts greatly against the proper and perfect businesswoman image she has. Scots was the obvious and most fitting choice, in my opinion, specifically because it brings with it a similar stereotype, and is hard to understand for many who are unfamiliar with it, just like a Hakata accent, along with being easy to convey in text, unlike most other accents (compare written American vs British English).

The grave miscalculation of mine, however, was that I'd never realised just how much people hate non-American standard English. To me, it seemed natural that if a character has a heavy accent in the original, I'll translate her with a heavy accent as well. I have also seen Scottish used in other translations, even official licensed releases, for example an old favourite of mine, Excel Saga (big surprise, I'm sure), where one character's Kansai accent is rendered as Scottish, and written in an extremely non-standard, mainly phonetic way. This is to say that I knew that this was something even large publishers do in their translations.

As I mentioned — even though I've developed rather thick skin after getting into scanlations — I felt horrible after the initial backlash, and almost completely lost motivation to work on the series, however after hearing voices of support from fellow translators and Japanese readers who can tell just how #thicc Nanami's accent is, it made me feel that I made the right decision after all, as many of them agreed that it would be somewhat of a character assassination to make her speak standard English in the translation.

TL;DR
I've heard the negative opinions, and I understand where you're coming from, but understanding doesn't mean I agree with you. The accent stays, because I feel that it is the best way to translate convey the original content in English. You can either accept it, or move on.

I will be moving on, but I hella respect what you're saying my guy. Keep it up, see you in the next story!
