Issei doesn't need Raynare at all because Akeno is considered the most hottest and sexiest among the Fallen Angels because Azazel remarked this about her, and he says that her potential in beauty and sexiness is off the charts, and he also compliments her potential in magical power as well but it seems to me that Akeno is someone important to Azazel because he regards her as someone important to look out for.
