Actually its 8 not 7, but I agree, heck Issei may have over 20 wives if he uses all his pieces indiviaully, that's 15 brides, then 3 from Rias Peerage, including Rias herself, and the independants. such as Kuroka, Le Fay, Kunou, Yasaka, Roygun, Elmenhilde, that's about 24, but could be less if Elmenhilde and Le Fay joined the peerage
