The oversaturation of any genre tends to result in some truly terrible pieces of media coming out - after all, the more there is of any one type of fiction, the more likely it is that any one piece will plumb the darkest depths that media as a whole has to offer.
This manga is NOT one of those series. You see, it doesn't have the decency to be terrible in a way that's interesting. Instead, it has all the traits you'd expect of an isekai, and then literally nothing else.
The overpowered protagonist, solving problems immediately with zero dramatic tension involved whatsoever? Check.
The endless gags about how the protagonist is underestimated repeatedly in spite of this overwhelming power? Check.
The annoying overexploration of the gamey systems inside the setting that somehow never manage to replicate the joy of discovering new tricks inside of a video game? Check.
And then... That's it. The supporting cast essentially only exist for the main character, Yuuji, to solve problems for immediately and thus surprise them. 11 chapters in, and I don't think he expressed a single opinion that was interesting.
It doesn't even make much of an effort to make use of the main character's monster taming gimmick for interesting setpieces - instead, he'll simply kill any enemy he faces with overwhelming magical power from the titular second class he has, and then go along with his day. Indeed, sometimes the story even seems to go OUT OF ITS WAY to make sure the narrative is as uninspired and bland as possible.
Nope, this series doesn't have the decency to be awful. Instead, it is simply... Nothing.
