6

Issei transfers his boosted powers to Rias, but both Rias and Akeno are overpowered by Kokabiel. Realizing Akeno is the daughter of the Fallen Angel Cadre, Baraqiel, Kokabiel mocks Rias saying that she has a habit of taking in weird people like her brother. Enraged by these insults, Issei plans to attack Kokabiel. Kiba, Xenovia and Koneko attack Kokabiel to buy time for Issei to boost his powers however, but Kokabiel overpowers them. He then reveals that in the previous Great War, both the Four Great Satans and God were killed, much to Xenovia's horror. Despite this, Issei strongly states his dream of becoming a Harem King and attacks Kokabiel, reigniting his friends' fighting spirit. Before the fight can continue, the barrier surrounding the school field is destroyed by the stranger. Naming himself as the White Dragon Emperor Albion, he defeats Kokabiel and negates the self destruct spell on the school, before taking Kokabiel and Freed away from the field. With Kokabiel gone, Sona and her team proceed to fix the school while Kiba vows once more to serve Rias along with her other servants. The next day, Xenovia, now having been reincarnated as a Devil as Rias' Knight, joins the Occult Research Club and reconciles with Asia. Issei later plays a video game with his client, who reveals himself to be Fallen Angel Leader Azazel. (Source: Wikipedia)
