I don't think Irina should join the Peerage of Naruto because she is a Angel unless she wants to turn into a Devil but the most appropriate person to join would be Ravel because she is  a free piece, and she did this intentionally for this reason but Issei is so dense that he couldn't figure out what  Ravel was doing, and he still hasn't noticed that she loves him yet because he has come a long way but his denseness still remains.
