Brave Soul Is a game that does not have an official soundtrack, so your best option is to use a video game sound converter. You may also try to use ExtractData v1.2
I would try searching inside the game folder for any audio files (ogg, wav, etc). If you don't see them, start looking through any large files with either of those scanners. If you get a weird format, use the sound converter. Ask around the Tech section if you need more help with converting stuff :3
Remember , Hentai SAVE the world.
You are here because your parents did something HENTAI before . If you enjoy in any hentai product , don't forget them .
Always be grateful
