I was wandering the same, but maybe it's a bandit skill?How'd the dude steal his sword on page 10 when you see him lunge past, his hands are completely empty.
for others it may be sociopathic but for me it seems like it is just him adapting to a new world with different laws and logic. I see it as him adapting to survive which plenty of isekai dont bother to show. I like how realistic this one isThe MC feels a little sociopathic in how quickly he adapted to becoming a professional killer. He dispatched those bandits very calmly and systematically, as if he'd been doing it for years. Even if he has no emotions or guilt, it feels a little unrealistic that he'd be so good at it. Like, where'd he learn all those close quarters combat tactics?
