This isekai manga has a lot of potential. The story of this isekai is quite unique. The main character is physically weak but he has a big brain and it is quite nice to see a mc winning by using his brain instead of just overpowered cheats from the start. Characters are also quite good some female characters are a little bit dumb. The art is also quite nice. Overall it's a good isekai manga with a unique plot and a very likeable main character.
I don't know what it is but this manga feel's like a complete package. The characters are great and relateable(to some extent).
The story is nice, the mc is strong(mentally) and all of them just intertwine to become a good manga to read in general.
Give it a try i highly recommend it.
