"I'm Here to Keep My Promise!" is the twelfth episode of the High School DxD anime, and the final episode of the first season. It premiered on March 23, 2012.


When Issei wakes up, finding himself passed out on his own bed after the Rating Game against Riser and his peerage, he blames himself knowing that it was his powerlessness that forced Rias to resign. Soon after, Grayfia, Sirzechs' Queen, arrives at his home and gives Issei a magic circle that will allow him to attend the Gremory-Phenex engagement party in the Underworld. When Issei arrives at the designated area and blatantly crashes the party, Sirzechs interferes, offering arbitration terms to settle the dispute by hosting a one-on-one battle between Riser and Issei, with Rias' engagement on the line. However, when the battle begins, it is shown that Issei traded his left arm to the Dragon that resides within him, in exchange for extreme power that will only last for 10 seconds. Issei is able to overpower Riser with his newfound power, but is unable to defeat or deal him critical damage, due to the latter's constitution as a Phenex, especially in the brief ten seconds window he has. However, even after the ten seconds are up, Issei manages to win when he surprisingly attacks a slightly-weakened Riser with holy objects, that he had earlier acquired from Asia, causing the latter to experience excruciating spiritual pain. After winning the battle, it is revealed however, that Sirzechs would have, if necessary, allowed a Griffin to assist Issei in his battle against Riser. The episode ends with Rias kissing Issei while flying on the Griffin and then cuts to a moment where Rias tells Issei's parents that she plans to move in with him.
