Ok, I'll be honest here: I am an avid lover of all things isekai. My standards for isekai and isekai related things are extremely low. And I found this show to be abysmal. I've even read the manga, and idk if I just payed even less attention then, or if the anime is just worse, but man I could not get through this show.
Characters:
The characters are extremely 2 dimensional, even for an isekai. They are all extraordinarily overpowered, but without any reasons or explanations. A couple of them can just be explained by them being extremely smart about a specific subject, specifically the businessman and the politician, but for characters like the swordswoman who is just ludicrously strong somehow with no explanation it just feels lame. We see shots of her in the real world charging on the front lines in a war, deflecting bullets like Kirito from the ggo arc. The ninja/journalist girl is just a naruto character who never bothered to learn any attacks other than a tazer that she carries around. The engineer girl just is some super genius that would make Senku jealous, without any explanation how. They make a nuclear reactor in the new world almost immediately. There's also a magician kid who is supposedly just using magic tricks from irl, but does stuff like save an entire village from a fire, and then make them reappear from thin air a few full minutes later and they all go "whoa, we're still alive!" so did he chloroform them or something? How do they not all know what just happened? The characters all make the concept of Kirito being Jesus look like you're trying to call an inchworm God. They can just do whatever the show wants them to do. Oh, a big monster showed up? Sword girl can just cut it once and it's dead. You get the picture.
Events:
To say that things get off to a bad start would be an understatement. One of the very first things to happen is that a Leafa knockoff without wings decides the best course of action is to chew up food and then feed it to the "MC" (politician) mouth to mouth style. (btw to reinforce the Leafa connection, in the dub they have the same VA even.) She also of course gets kidnapped to be raped within the next few episodes. In between those two events there's an arc where the businessman goes to the city to sell stuff, and that part is honestly legitimately somewhat interesting, but that's about the only good thing I can say. The whole kidnapping thing immediately afterwards involves a guy who looks like if pot of greed was a person. Seriously. Look at them.

This guy's castle promptly falls to the village armed with some magic super metal shields that are super light and strong so the villagers can storm the castle easily. Meanwhile the great wizard of the castle gets beaten by ninja girl cause he sucked, and MC scares the lord unconscious using a gun with rubber bullets. (cause actually killing him would be
wrong of course)
Verdict:
Just don't watch it, it's not worth your time, unless you're truly a degenerate isekai lover who's watched everything else out there.
