This one is really good, unlike the other Isekai out there, this one is actually interesting. It's like reading Code Geass but the MC has no Geass, everything the MC does is calculated according to the facts presented to him, able to conduct critical analysis and come up with solutions accordingly. The MC is not some dude who has no power but will be ultra OP in the future, nor was given abilities that are "absurd", or abilities that you think is useless but it was actually broken, No, it's nothing like that, the MC is just a very smart dude, it's definitely a title worth reading or at least, it's better than most Isekais out there in my opinion.
