Whoops, my bad. Not paying enough attention (^ ^;)

I believe the fact of Lavina being the Absolute Demise possessor is quite high now. We already know that Mephisto and Azazel had links prior to the events of HSDxD. This could be one of them. (Perhaps we'll see more of Grauzauberer in this series.)

On a separate note, checking out the kana for Demise from Absolute Demise confrims that her nickname is indeed "Demise Girl". (headslap for not thinking of that earlier)
