first ~13 chapters need a translation overall, but besides that this manga kinda slaps? Protag is OP because of technology disparity, magic is written as some pseudoscience thingamagik, but it is suficiently believable in that universe. and the plot has a clear objective from the start that makes sense and it's urgency forces the protagonist to be an active force in this universe (something that is rare in most isekais). This is the most literal definition of an "isekai" you will ever get. It's literally another world, anothe freaking planet, and the plot appears to be going in a literal galactic warfare. If you are a fan of sci-fi AND a isekai trash like me, you'll probably like this one.
