Three Beastketeers

Three Beastketeers (三獣士) refers to the three Beastmen Albis, Suphia and Phobio who within Beast Kingdom Yuurazania are second only to Demon Lord Carrion himself.

Social Influence
They are highly respected in Yuurazania and after Carrion's temporary disappearance, they held enough sway among the beastmen to get the army to agree with fighting under the command of Tempest's Benimaru against Clayman's forces.

Structure
As Yuurazania is a meritocratic nation, the positions of the current Three Beastketeers aren't guaranteed. If someone stronger appears among the beastmen that desires one of the three positions, then the current members will have to oblige the challenge and will be replaced from their position if they lost.
