Synopsis
As summer break arrives for the students of Kuoh Academy, the Red Dragon Emperor Issei Hyoudou and the Occult Research Club are back in action. Their battle against Issei's sworn enemy Vali and the Chaos Brigade made it evident just how inexperienced Rias Gremory's team is. To prepare for the trials ahead, Rias and Azazel lead the club through a rigorous training program in the Underworld. While the team gradually matures together, Issei once again finds himself in intimate situations with the girls of the Occult Research Club. Meanwhile, their opponents grow stronger and more numerous as they gather their forces. And with the sudden arrival of Loki, the Evil God of Norse Mythology, the stage is set for epic battles and fearsomely powerful devils in High School DxD BorN!
