Finally, the inner face of the government and the strongest warriors above the admirals will move after all. The strength of the Holy Knights must be hidden from the rest of the world since they are the internal force, while the external face is the Marines that the whole world knows about.

Now everything makes sense.
And to think that the Five Elders fear to anger Kaido even with the support of these nine Holy Knights is insane, the level of presence that Kaido has reached in the world as the strongest is remarkable.
