Yep, if anything it's just not in the present where Issei's peerage is still incomplete anyways.Now that I think of this though, you think any of Issei's pawns may need multiple pieces?

We know Issei will have more than 20 kids in the future, if we count each kid belonging to a different mom, how many new woman could Issei put in his peerage? If over 20 only reaches 21, then counting Kunou, that would make 9.

Since she still has all his pawns, a rook, a knights and his queen piece, that's 11 spots unless Elmenhilde takes one of them which makes it 10. So unless another girl we've already met gets added, one of them will need to take two pawn pieces.

Though this is only if the most of it not the rest of Issei's harem are new girls and they all join his peerage.
