After Fein listened to James about the numbers of S ranks in each region, his understanding of the balance of power on the continent was further enriched.
Though, James only knows the specific detail of the North because their mission forced them to say in the North for years. As for the other regions such as East, West, or even the mysterious Central Plains... He only knew the total number, but not the specific number of the countries.
For example, East has thirty-five S rank degu users, three more than their South. But James didn't know the distribution or the specific number of S ranks each country possessed in the East.
