The Saint's Magic Power is Omnipotent uses the standard isekai format to tell a pretty low-key romance set in a fantasy kingdom. Those wanting a deep dive into world-building will be disappointed but those just after a calm viewing experience may find a bit of joy in this one.
I really should learn to play by my own rules. After abandoning Trigger's SSSS.Dynazenon by the end of episode 1 and not even making it through the introduction of Combatants Will Be Dispatched I was a little worried that I wouldn't make it to episode 3 of enough anime to continue this post format. Well, I was saved from abandoning Watch or Drop by The Saint's Magic Power is Omnipotent, though I didn't quite remember to stop at the end of episode 3 and snuck in an episode 4.
Domestic Girlfriend is melodrama from start to finish yet somehow it is a train wreck of a romance story that managed to keep me watching even while I wanted to bang the heads of all of the main characters together. I know this review is late but here are my whole series thoughts of Domestic Girlfriend.
