Not sure about the Valerie and Le Fay suggestion.

Disagree with the pawn idea, due to the fact that Issei wants to become King of the Rating Games.

Love your knight idea, the Angel/Devil hybrid, but not with Irina. What if Issei meet a Human/Angel hybrid ,girl or boy, that wants more power for some reason, Issei hears him/her out and  reincarnates as his Knight, making and Angel/Devil hybrid.
