The art IS amazing, but the story definitely needs to progress faster. It's been so long (I don't know how many chapters and how many months) but the MC is still struggling against I don't know what. Just look at the past few chapters, how many moves has MC done against the magician, compared to the lengthy epic fights of the side characters? MC should have killed (I refuse to call this assassination) the magician already and not allowing him to talk shit, posing, watching and controlling his slaves, and even manipulate the civilian that stabbed the princess.
