I really wonder how closely the manga will follow the light novel. I found it interesting at first, but after a few chapters of the novel, it just went straight to poo poo land. MC gets everything the way he wants it, with OP power, no one can defeat him, and the adventurism degenerates into more like slice of life of eating, sleeping, and going on dates. Then the jokes and misunderstandings decrease in creativity. Some things don't make sense, like how enemies can hear each others' radio communications (don't they have encryption? Why do they all broadcast on the same radio frequency?), there is a lack of explanation about how the MC knows how to operate all the futuristic devices, and why his isekai spaceship is compatible with that universe's technology.
