I believe this covers all the languages that were requested. Thank you all. However, please note that since I am a developer who only speaks Japanese, these translations were done using machine translation for the sake of speed. There may be inconsistencies in terminology or other issues. Also, because the text length often increases when translating from Japanese to Russian, there might be some UI glitches (this may apply to English as well).The translation data is publicly available, and anyone can suggest corrections. Even if it’s just for one small part, any help in refining the translations would be greatly appreciated! https://github.com/uskz/arai_Localization

You can learn about them at the church.The meaning of the arrows is based on a tweet by Abubu, the original creator of the Arai-san Mansion series.The information was also quietly mentioned in the Censored Document, but we figured it would be better to have a cute Friend explain it to you.

AI Language Fix (Hopefully!)I think I’ve fixed the issue where the AI was generating text in the wrong language, ignoring your actual language settings. ...Let me know how it works!Before: The base prompt was written in Japanese, and the game would just tack on a line saying "Please output this in \." The AI was completely ignoring this request.After: I rewrote the prompt for each individual language. It should work properly now... probably! 🤞
