It's a position within Rou's Psalm. It's similar to the 4 Symbol Heroes of the Kingdom, the 8 Great Knights of the Empire, and even the Generals of the Beast Kingdom and Demon Empire. So it IS a rank, in that it appears in the National Psalms of the human kingdoms for their heroes and the Sovereign Psalms of the monster kingdoms. However, it's also an affiliation in that it's a relationship that connects each character to a greater Psalm (the individual Hero Psalms are subordinated under the National Psalms; I assume, if the 8 Generals get their own Sovereign Psalms, they'd all be placed under Rou's World Psalm).
