These are the thieves of Riften after all, they live in the sewers. While there’s strictly no need for NPCs to swear, one could argue that it gives them character.
I’m sure you can guess what the changes entail. To be more specific, there are lines where the characters use the word ‘muck’. It changes certain lines of the Thieves’ Guild NPCs to make them swear more. If you don’t believe me, just take a look at the video! It makes you feel like you’re playing an anime. The biggest appeal of this mod is how dramatic everything seems. The audio files are from Skyrim’s Japanese version, so everything is very high quality and professionally made. You might be wondering, why would I want to do that? The answer is because it’s pretty epic. This mod simply replaces the English voiced lines with Japanese ones. Especially if you’re a fan of anime and can appreciate hearing a foreign language while reading subtitles. But for the most part, I’m completely serious about this mod. Sure, it sounds like a bit of a joke entry, and it kinda is. Before you go around raising your eyebrows, let me clarify and justify this entry.
