Need help extracting assets from Android app that require internet

[otchi]

This is the APK of the app. Not sure if it helps, since extracting data from the apk doesnt' give me what I needed 


Link to APK download

This is what the folder with strange numbered files looks like. I thought this was the databank of the app, but I couldn't identify the files to extract them. Sample of one of the file in the folder i linked in the first post
