I will keep this review pretty brief, as it's my first one.
Firstly, I greatly enjoyed this story, mainly because it's really... chill. MC marries a demon that he defeats, gathers some... students? Idk what to refer to them as, and resolves some conflicts that I won't spoil.
The story was an 8 for me, nothing too special really, but nothing too bad either.
The art was a 7, typical isekai manga art quality
Character was also an 8, don't have much to say about this one, ngl
I thoroughly enjoyed reading these 18 chapters. I am a pretty big fan of generic isekais, but I enjoyed this one a lot more than most because MC actually chooses a girl instead of being an indecisive pussy. Note: This isn't really a spoiler because it happens in like the 3rd or 4th chapter
Overall, I gave this a 10, but since the only thing that was a 10 was my enjoyment, I reduced it to an overall 9 because I realized that not everyone may have the same tastes as me.
