A problem revolving Grand Summoners rips

[Honeybeetle]

I'm trying to extract & find a certain type of sprites in the Game Grand Summoners. Specifically, expressions like this!
 

But I don't know where to properly start looking. downloading the apk and turning it into a zip won't work, as nearly everything is downloaded from an external source. And I'm not sure how to access that either. Any pointers?
