[Zero-Raws] M3 Sono Kuroki Hagane - 19 (MX 1280x720 x264 AAC).mp4

Still working on what is causing this but any MX raw that is having sync problems, to fix you need to add a 500ms delay. This can either done directly in player or remuxing file.

Again this same delay should work for any MX raw that has sync issues.
