This is kinda cringe. Im just realizing that this genre of returner + system is as stupid japan's "party kick" genre but just pathetic. Its cringe that the mc of this genre is dependent on the system rewards when its source is a mystery + how the quests are not comparable to real proper training. Power is just being mouth fed to them.
But at the same time, i do find it make sense because they are innately weak so they need and are desperate for any power possible but still incredibly lame. And this mc here is acting very confident but i find that degree of confidence on a pathetic person to be a very weird contrast.
