Review Detail of Quentinql in Skeleton's Training Manual

Really? Between insults and abuse on obese people, the story is barely advancing around chapter 40. 40 chapters of jealousy and insults on a small Skeleton, so sad. I understand that Skeleton is epic trash but there should be limits too... About the background why do they have to improve the spirits? A big lack of objectives, no invasions of monsters or parallel universe to explore,and even less of super vilain so far...
