...Of course Tamamo speaks Gyeongsang dialect. That's like Korean Kansai, and I think the usual go-to dialect when adapting Kansai-speaking characters. Like how English TLs tend to use Southern American dialects.

Busan is kinda like Osaka too.

Now I just need to find a reliable Gyeongsang/Busan phrasebook somewhere online...

(The Japanese version has a decent attempt at Kansai for Tamamo's lines, but the meaning seems to differ somewhat. Notably the Korean-Gyeongsang lines are more expressive and have more slang words.)
