so, a vague comment here to avoid any spoilers or words that may come across as offensive, I feel like this manga has explained each piece of it's worlds lore so far including each system or "trade" that's been mentioned. it's also went into detail on each character not with personal information yet, but by showing their likes and how their personalities align. It's a well illustrated piece of work that feels like it was written with a lot of love given to the concept.
