I was trying to avoid this by saying a Grim Reaper that is not Bennia

@Pawn I agree with you there no more trades for Issei.

Personally I think Bennia belongs in Sona's Peerage and shouldn't move but another Grim Reaper wouldn't be all that bad.

If Ishibumi wanted he could even write it into the story along the lines of said Grim Reaper defects from Hades with the information on Lilith and finds Issei because of how much Bennia kept on talkig about Oppai Dragon thinking it is the easiest method and so on so forth ends up as a member of Issei's Peerage. (can't think of the rest of the plot in detail right now)
