An unfortunate shortcoming of this series will always be the inability of it’s side characters to increase their power. Even if Johee did overcome her mental trauma and return to battle, she’d still be useless in the long run. I know it’s “Solo” Leveling, but this arbitrary limitation really kneecaps the story’s options for building drama. How many times can you milk the ‘but he’s just a E-rank/S-rank/human/Tarnished, how can he be this strong!?’ Formula before it wears thin?
