The alleged No. 1 knight was similar to a nationwide employed knight. The only difference was that nationwide employed knights served a nation or royals while employed knights served clans that had not established countries. If demons completely occupied Blackson Humans Corridor in the future, Senel Clan might be rewarded with a nation. If so, that knight employed by Senel Clan might be the No. 1 knight of their nation or a corps leader.
Any knight would be at least a corps leader in Blackson Humans Corridor if they took an office in the army. However, there were many human countries in Blackson Humans Corridor, none of their armies contained more than 400,000 soldiers. None of the countries were able to establish and sustain the needs of a corps. Therefore, if one country could have one knight on their side, even if the knight could not take the office as a corps leader, he would become the alleged No. 1 knight of the country.
