TL;DR: if you're looking for a quick-fix, then this is worth a one-time read. Wouldn't recommend it for anything else.
It's about as standard as it can get, with a few slip-ups here and there. The complaints are pretty much the usuals, so i don't think there's a need for me to say them. Instead, I'll point out why I've decided to keep this in my bookmarks for now.
1. The characters aren't all that bad. Sure, we know very little about them and certainly not enough to root for any of them at all, but that's probably because of the janky progression this story takes. Since it tends to jump all over the place, it really doesn't give enough time to flesh out the characters. Now, one might say that it's been only a couple of chapters to which I'll respond simply by saying that it can be done. Whether you believe that or not is entirely up to you. Just know that at the very least, the characters here despite not being fully developed are by and large not entirely unlikable, cliche as they may be.
2. There's nothing spectacular about the plot, art or any scenes, but they are still rather entertaining.
3. You won't feel the characters threatened at any point in this manga. Not even with the cliffhangers they give you at the end simply because this does a poor job at foreshadowing. However--which is to say, bullshit incoming--you'll find yourself still turning pages precisely because of that. This is has the feel of a comfort manga that disguises itself as action with some mystery. Like Blue's Clues, in a way.
4. It doesn't obsess over one thing. Unlike other mangas trying to cash in on the isekai genre, this doesn't obsess over one aspect. Say, for example, that the character is supposed to be smarter than the rest and the manga would continue to emphasize that over and over to the point of being unreasonable and grinding. While this manga still does like to make that overtly obvious, it's not too annoying.
5. The slip-ups aren't key to anything. That's always a good thing, even if there were a number of them. Since they don't really have that much of an impact on anything, you could practically treat them like wandering dust. It's uncomfortable to the touch, but not something that's worth paying too much mind over.
All in all, I'd say it's ridiculous and terrible, but a comfort nonetheless.
