I just finished the update, and it's another one I enjoyed very much. To be honest, I didn't care too much about the D&D portion, but I understood it was meant as a bonding experience with the girls. To be honest, I'm glad the MC was eventually caught by Jasmin and partially Asuna, because I would hate for any of the girls to get badly caught in a war that they had no knowledge of or at least couldn't prepare for. Specifically, Jasmin being the first as like the MC stated, she mirrors his younger self a lot to a perhaps scary degree, and also comes from a rough neighborhood/bad childhood.
Next, I wasn't sure how to vision Isabella fitting in with the harem, but it seem to be that Isabella is going to be the pillar that holds up the bridge connecting Sophia and the MC on Sophia's end while Ava is the pillar holding up the bridge on the MC's end. Sophia is definitely the head mistress (No.1 woman), but will be/is heavily supported by the likes of Ava and Isabella to keep things in order as their family continues to navigate through this world together.
Going back to Isabella, unlike Ava, Isabella has a past she very CLEARLY remembers (although traumatizes her), which in my opinion, makes Sophia less guarded as opposed to her treatment towards Ava (who randomly memorizes information from her past that honestly someone like Sophia or the MC would know from their experiences), which helps keep Sophia's mind off the fact the MC is very secretive and hasn't recovered mentally from Ingrid and the MC's child sudden deaths. Additionally, Isabella is a former surgeon and is in the same age bracket as Sophia, which has shown before to relax Sophia as she now has a second opinion in the field of medical expertise. Lastly, the fact that Isabella cares deeply for the MC and is so far willing to accept his highs and lows as a character (the type of man that she needed badly in her life). I can't wait to see more of this home harem dynamic as the story progresses.
