Familiar Of Zero:F Season 4

Saito and Louise's relationship has come a long way since Saito was accidentally kidnapped from Earth and became a familiar. But it looks like it'll be coming under the ultimate challenge when events in Halkeginia are spiralling out of control and several Void Mages are called to service to save the world.

For Louise, she's forced to team up with elf Tiffania to become holy maidens under the ever-watchful eye of the pope. Competition, confusion and even more complicated emotions, run amuck as our oddball couple struggle to survive!
