Red And White Dragon

Albion and Ddraig were always rivals. That was until a hybrid was born and the Luna Goddess came to them and begged for them to protect her. The Four Great Devils kings and God did not like this creature and had her executed. Albion and Ddraig went on a rampage and were sealed in the sacred gears. There they fought over and over blaming the other for their failure. However there was one thing they agreed on, if ever another Hybrid was born they would get along and protect her. So when Issei gets betrayed by the one he loved most. Due to the fact that Rias was Issei's mate and she betrayed him, Issei was on the verge of death. Serenity Fujakante, Vali's destined mate, finds him and decides to save Issei by marking him as hers. Much to Vali's dismay of having to share her with his rival, Issei was quickly added in Serenity's harem. Issei isn't the only one to join The Vali team either. When a certain black haired boy comes begging for Serenity's help with a familiar incubus, Vali realizes that he might as well accept the fate he has to get along with Issei.
