It’s barely an isekai. MC is a clueless edgelord. His past life is meaningless. He’s super secretiv yet constantly gains attention with his deeds. And his gun can only be used by him so no one could use it if they got the thing. There’s also the most pointless, drawn out battle in the teens chapters that will make you quit the title.
Dont waste time on this one. Also the scanlation is one notch above MTL.
