I took the Japanese version (No additional decensor patch needed) and MTLed it line by line while also performing edits and rewrites where MTL output was still kinda odd.

For MTL DeepL and Sugoi Offline Tool was used. (Basically inserted each sentence into both and looked at which produced better results, occasionally mixing and matching until arriving at final line ingame)
I don't know if it's better than Steam version's MTL, but I atleast hope it won't be worse.
If any errors or typos are spotted let me know.
