Lv2 kara Cheat is okayish... The reason I still went for the recommended review instead of mixed feelings is because I think it's enjoyable for people who already like and enjoy watching isekais. If you've never watched one, you probably shouldn't start with this one, and I'll try to explain briefly why down below.
This anime is clearly aiming for the average, and it will check many boxes of the isekai genre : op mc, pseudo harem, basic plot, average animation quality etc... And while a few elements are done right such as the number of characters introduced, the female MC, the opening song, the slice of life vibe and the development of their home/everyday life, there are also many elements done wrong. Indeed, the plot is forgettable, the rhythm is fine for the first half but it becomes too slow afterwards, and it highlights another problem : there aren't any real stakes in this anime, and it would be fine with different settings, but here, the plot involves a global war between demons & humans, so the end result is a bit weird, why should the viewers care about the plot if even the characters don't really care for it ?
Now to be fair, the anime doesn't take itself seriously, so it's easy to forgive the show for its absence of stakes, but the fact remains that the rhythm feels off after a few episodes and it becomes a bit boring at times.
All in all, this show is a typical isekai, it will please people who enjoy this genre and it will annoy people who don't. The anime does manage to establish a cozy light hearted vibe and it's interesting to see the characters evolve in their everyday life. However, the absence of stakes hurts the show and its rhythm, in the end, there's not much happening in the span of 12 episodes and people who aren't used to fantasy isekai animes might feel confused because the last episodes are really underwhelming. I liked Lv2 kara Cheat for what it had to offer but I wouldn't recommend it to everyone, and there are many better isekais to watch beforehand.
