The Black Death Emperor Front (黒死皇派) or the Black Death Emperor Faction is a beast man–supremacist terrorist group. They were the group responsible for activating the ancient weapon Nalakuvera. Their objectives are the complete rupture of the Holy Ground Treaty and striking down the First Primogenitor, who rules the Warlord's Empire.
The group was assumed to have been wiped out years ago, when Dimitrie Vatler killed their leader. Kristof Gardos was a survivor of the Black Death Emperor Front, who became their new leader. At some point, they occupied the National Assembly in Prague, resulting in over 400 casualties.
