Genkai Zero: The Zero-Limit Outcast

I use AI to proofread this only. Cover is made with AI, sorry :,( After the events of the Demon Emperor's attempt to rule the world, Kazuki Sorano, a D-ranked adventurer, faded into the background as the hero who defeated the Demon Emperor. No matter, though, as he continues on his way to explore more of the New World, the generation after the terrible rampages of the Emperor. As Kazuki encounters people along the way, some wonder how could he could still be in D rank when he possesses incredible abilities beyond S rank.
