Well... For some reason I was mildly interested in the original novel without knowing anything about it. Now I'm not interested anymore.
Oh, yeah, after I recommended it to you I decided to go and see how the anime is compared to the source material. I'm not sure if I actually watched it to the end. I think, there were still one or two episodes left. I think it gave the source material justice, as far as I can tell, considering that I read it years ago, before it was officially picked up for translation. They completely got rid of the game-like level system, but, honestly, it was only mentioned in the novel a few times anyway, and the anime pretty much showed everything that it implied in a different way.
I believe I mentioned it in the past, but the story being very wholesome is exactly the reason why I enjoyed it so much. I understand what you say about the world being convenient and the romance being cheesy. And, truth be told, I probably won't finish the novel since I pretty much got enough sweetness from this story already, and it's time to move to something else before it gets bad. On the other hand, I'd say that the fact that the conflict is nonexistent is a massive advantage this series has compared to many other "wish-fulfilling" female-oriented isekais. Honestly, I find it extremely annoying how many of isekais, both female and male oriented, add cheap badly written angst and drama just for the sake of there being drama, and to make the later "healing" parts seem different. Usually, the protagonist is literally the kindest and the most gentle person ever, but everyone bullies them and hates them just because they are assholes or idiots, and etcetera. Actually, this novel/anime manages to subvert many cliches typically associated with the stories like that. It's has an extremely common beginning, with two people being summoned, and the MC being neglected after that. On the other hand, the MC quickly found her place in the world; the other characters realized her worth and didn't try too much to make her life miserable due to their stubbornness; and, finally, the fact that the other summoned person didn't turn out to be a literal Hitler in a body of a schoolgirl. Overall, this story is still very cliche, but the fact that it skips these particular tropes, in my opinion, just make it feel more tasteful. Sure, it's a wish-fulfillment story, but it doesn't pretend to be something else, and it does the job it takes extremely well.
I'd watch this series after a difficult day or when I feel bad. I wouldn't recommend to watch it if you want something epic or something like that, but it should be given.
Well, since I read a lot of female-oriented isekais in novel and manga format, I pretty much got to the point where it's hard to impress me, and I find many of the common tropes extremely annoying. On the other hand, for some reason not many of them go this particular route. And, like we should probably expect from something that originates from web-novels, the writing in most of those is a lot worse, so I'd say Seijou still stands out.
