Wow this author really knows how to balance the OP isekai factor with the nitty gritty details of the world's mechanic without making it boring and cumbersome to read through. The way he maps out the world building is nicely paced and not to mention the great artstyle.
Personally i dont like the face of the MC but thats a minor detail.
Overall, the art is great, the pacing is good, characters are decent, MC is not a puttz and the development is good too, deep enough without being too philosophical. OP just goes "oh shit, I may be OP, but this is not a game, gotta get my shit together, and figure out how much ammo i need to achieve x,y,z until I learn more about this world".
Really common sense stuff you wish other MC shouldve considered. Im keeping an eye on how this develops.
