One thing that I find interesting, and am looking forward to seeing how it plays out, is that the protagonist explicitly rejected the goddess' divine strength. In a story like this, especially in the other series like sexiled or roll over and die that I mentioned above, the protagonists have a special power which gives them the capacity to triumph over their foes.
In this story, the focus on "brute strength" and on the societal belief of men being better than women is in the foreground, but by rejecting the goddess's power Lisa is explicitly rejecting that worldview as well. Rather than winning by way of the game set up by the male dominated society, she's forging her own path, with only her 150 years of training to improve her odds against her foes. It seems like she's explicitly intending on using skill and expertise to trump the brute strength that both the male dominated academy and the goddess herself claimed was necessary.
