Issei wakes up to find himself passed out in his own bed after the rating game. Soon after, Grayfia (Sirzech's wife and Queen) informs Issei the results of the Rating Game. She gives Issei a magic circle that will allow him to attend the Gremory-Phenex engagement party with Sirzech's message that if Issei wants to do something, then to go in and rescue Rias by force. Upon arriving, Issei begins to crash the party, but is interrupted when Sirzechs comes in and offers to host a one-on-one battle between Riser and Issei to liven things up since he found the Rating Game unsatisfying. Issei shows that he didn't plan on beating Riser by his feelings alone. After the match Issei finds out what was on the back of the transport circle Grayfia gave him. Sirzech comments to Grayfia his feelings and plans about Rias' forced engagement. Rias, overwhelmed by Issei's feelings and determination, acts on impulse. As a result of the duel between Dragon and Phoenix, some changes are going to occur at Issei's house while Asia and Akeno try to help him deal with the consequences of a choice he made.
