Good grief... concept was fine but all this bloody pointless fillers within fillers.... lets shove a pointless s rank guy fight to pad out a fight with the villain for 1 more chapter to only show that idiot die. Maybe if mc wasnt already op it might have added tension to make it seem like the villain was "strong" but its piss obvious hes still leagues below the mc..
.. and then we have this brilliant idea of "blackmailing" the mc coz that would never ever backfire...
