If you've never worked with a .ass file before: 1\. Download the video file [here](https://www.nyaa.se/?page=view&tid=912534). 2\. Rename the video file to match this .ass file (or vice versa.) Make sure they're in the same folder. 3\. Open the video file in any decent video player. The subtitles should automatically play, and should override the subtitles included on the files.
