Quick Note

What if Serenity was given to Vali by Issei all so Vali could help them save Rias?? What if they met that way instead of Vali saving her from getting raped? Serenity Hyoudou was adopted by the Hyoudou's when she was three. When Rias showed up Issei started to completely ignore her. When Rias was kidnapped Issei went to Vali for help. Vali refused because he wanted something in return. So Issei gave Serenity away. An Alternate Universe of The Lucifer's Greatest Treasure.
