High School DxD BorN

Summer break arrives at Kuoh Academy, but Issei Hyoudou—the Red Dragon Emperor—and the Occult Research Club don’t get much time to relax. In the wake of their clash with Vali and the Chaos Brigade, it becomes obvious how far Rias Gremory’s peerage still has to go. To close that gap, Rias and Azazel push the group into a demanding training program in the Underworld, aiming to toughen them up for what’s coming next.

As the team gradually sharpens its abilities, Issei’s days remain filled with the club’s trademark flirtatious chaos and romantic complications. At the same time, new threats begin to gather strength, and the unexpected arrival of Loki—an evil god from Norse mythology—signals that even bigger supernatural battles are on the horizon.
