This is way too early for me to properly review this manga (not sure how the story will develop, never read the source material either), but my first impression is:
Came for the trashy OP MC trope (based on this comment section)
Impressed by the art (the power of money & resource of Squeenix production house, I guess)
Stayed for the DIVINE COCK GERBERGA-SAMA
'Nuff said.
