I don't usually give things a 1 very often, but the story in this is rushed and incomprehensible, and the art is bad to the point of being unrecognizable, inside the first four pages of chapter 1 the kid has already grown up, gotten non-specific powers, and now he's fighting... an old man? an owl man? who has a third barefoot leg sticking out of his cloak? Chapter 1 Page 7, look at the lower left panel and tell me if you can understand what is going on there or not. A couple pages later now it's talking about an A rank dungeon? What are the rules of this place? What powers does this kid have? Who are these people? I don't know who anybody is but the main character is already fighting some big animal, and now there are more animals?
This whole story feels like it was written by a kid, without an editor, who just got bored in-between each panel and couldn't keep things coherent between more than about two pages.
