Issei and Kiba begin their fight against Irina and Xenovia, both ultimately losing to the latter two who then leave with Issei and Yuuto frustrated at their loss. Before leaving, Rias asks the two about the Fallen Angel who stole the Excaliburs learning that the one who was responsible was the Fallen Angel Leader, Kokabiel. Back at the Occult Research Club, Yuuto leaves the building with extreme frustration over his loss to Xenovia. After seeing Yuuto leave the clubroom with such frustration, Issei decides to help Kiba in his revenge against the Excalibur swords. Coercing Saji into his plans with Koneko's help, the three start to search for Xenovia and Irina, eventually finding them in a street. The trio then form an alliance with the two, helping them to retrieve the Excalibur swords while handing them an Excalibur sword so that Yuuto can destroy it. Kiba, touched by Issei and Koneko's action, agrees to accept the help of the two, thanking them for their help. Later at night, Issei meets up with Kiba and the others to start their plan to destroy the Excalibur. Meanwhile, a mysterious young man appears beside Issei's client.
