Jump to TLDR if needed.

A japanese friend wanted to get the audio and video from an Android game (and Japanese only). The game in question seems to be an horror game and not available anymore so getting information about it is hard. Play Store page of the game.

What he told me is that everything seems to be in an .obb file/archive and extracting it would be enough. So he provided me with a download link of the .obb file in question.

With a tool named "Extractdata" he managed to get the file address of the audio files in .ogg format. The link of the tool in English though I only own the Japanese version. The image below shows the analysis of the application of the .obb and indeed shows lots of .ogg.



So the audio are indeed rippable. I'm providing these informations because I think it may be useful. The thing is every .ogg of the .obb doesn't reach the total file of the .obb (which is like 10% of the total size). So the guess is that video files are taking up space in the .obb archive. The problem is now the video files. Is it possible to decrypt / extract them?






TLDR :
I need to get the video files from an .obb file which is an Android Japanese only game. The link of the .obb is here and the Play Store page of the game here. Are the video files rippable?
