-The Main Character
This lack of common sense shown by both the guild staff as well the the already registered adventurers shows the the foundation of the guild politics is completely missing and so each time it affects the MC the story just gets worse and worse.
-The Interactions between the MC and the Environment
For this section, I will not relist the failures between the MC and the adventurer's guild.
Each of these categories are individually very poorly written. There is no cohesion between the 3 at all. So no matter detailed or descriptive the author gets about a town, or clothes, or a characters appearance, or a battle, the story as a whole will still fail.
