The Paperman Clan has always revered the strong and left no room for the weak to speak, especially so amongst their own kind.
A Paperman of a higher tier, after defeating a Paperman of a lower tier, would dominate over the latter for an extended period and enjoy a certain right to command.
This right to command would gradually weaken over time, but could be intensified with another victory.
Of course, should the lower-tier Paperman turn defeat into victory, it would similarly gain the right to command, though the higher-tier Paperman might not accept this and initiate a second battle in a shorter time frame.
The unique racial dominance is a source of the Paperman Clan's belligerence, which is why Yu Liang seldom saw them coexist peacefully.
