Hmm, the lolibaba god that summoned Renya was the sole true god of the world they are in right now. She delegated her management tasks for this particular world to 5 "administrators", each one representing each race. The one that is about to be trashed is the administrator for humanity.
The odd point is indeed the fact that she isn't aware of the angel's master (which is obviously the lolibaba god), as lolibaba god implied she might've chosen the 5 administrators in person (as she drew a comparison as to how Renya dared to beat her up, unlike all of those she had previously chosen).
But yes, the lolibaba god can take their administrator rights anytime anywhen, although she claimed it'd likely destroy 80% of the world in the process. Though she also implied she could just recreate them. So as to not have to resort to that troublesome process, Renya was chosen as he conveniently bumped into this world's barrier due to his very thick soul. As far as my understanding went at least.

UPDATE: Later chapters implied humanity administrator aren't aware of lolibaba god in person, and neither about her gender (as the angel deliberately referred to her as Him).
