For those who are thinking why Vertrag(Father) is a Seven ghost and he died, cause he's already dead. In fact, all seven ghosts are dead, including Frau, Labrador, Castor and Lance. You can learn about Labrador, Castor and Frau's death in the manga. Get it???
0:19 : Labrador just stands smiling at Frau after Castor-san hit him 0:42 : Labrador has the cuuuuuutest face of them all! 1:19 : DAYUM that smile Labrador, its killin me ;3
1:01, hilarious ! I love those shocked faces The sisters are right, Frau is one of the Seven Ghosts ! Castor and Labrador-san too~ But because of Frau is a pervert (and I like it xD) they seemed doubted it xDDD
