Vali will never become a Satan imagine this

Ajuka: "where is the Lucifer?"

other Maou: "he went to get Ramen"

Ajuka: "when?"

Other Maou: "about a year ago"

I don't think Issei will become a Maou either he has to look after ExE if he becomes the leader of it and other things.

@Bennia Lover I put my money on Vali's Ane running the magician brotherhood while he goofs off somewhere.
