the rpg part of this manga was cool, everything since then has been who the hell are these characters, what are their motives, what are the rules...
didn't they time skip years of mc traveling, and im supposed to believe that after moderate character growth in the weeks/months of leveling up but talking to no one, she has zero character growth for years of traveling with people? that's utterly implausible and awful writing
also youd think changing into a cute girl would be a payoff moment but she looks so much less engaged that she was cuter as a spider
