I keep dropping this, coming back a year later and starting over.
Now I arrived at the 'let's be a slave owner!' arc again, and I'm feeling the resounding sense of 'meh' that means soon I'll leave this manga in a 'look at this later' tab and forget about it for another year.
Anyway, I rate this manga 6/10.
The main issue I've identified is that this guy doesn't solve his own problems. He's got a Skill that actively suggests what he should do, and then he follows instructions.
Basically he's on autopilot. That's the least interesting decision-making process imaginable.
So, Sapo is effectively the new protagonist now, but we have no idea about their internal processes.
