just did the same, i got my fill bc it's been a while since i read an revenger manga but i get u, at least now i can drop the anime, the animation was ass, be it 3d or 2d, and i anticipate an awful pacing too
anyone knows if will take much time for the next slave to be added to the harem? i like how things are now but its almost a slice of life in the last few chapters
my guess is that while the confrontation/battle with the big booby nun happens some other people will apear as the main villain behind everything, and since there is still the coliseum owner/manager to beat there's probably some more stuff to happen
