Actually, Diehauser's ranking can (and likely will) increase.

Since Sirzechs, Serafall, and Falbium are gone, new Satans will be needed. And before they left to seal themselves along with 666, they made preparations for a 7 Satan system.


 * Lucifer


 * Beelzebub


 * Asmodeus


 * Leviathan


 * Belial


 * Belphagor


 * Mammon (Don't know if I'm spelling that correctly)

Considering Diehauser's already prestigious reputation, this latest event will most likely garentee his position as a Satan. His participation in the International Tournament might even be a way for the Devil Government to "show off" their new Satan to the rest of the world.
