The Gremory group arrives at the temple where Diodora Astaroth is holding Asia Argento hostage. Diodora informs the Gremory group that even though he has halted the rating game itself because of the attack by the Khaos brigade he still intends to have the Occult Research Club fight his servants. To protect Asia the Gremory group agrees to split into two groups to fight Diodora’s Servants When Issei’s Dress Break on Diodora’s pawns and rooks fail, he uses his Bilingual technique on the girls. Using the information Issei provides, Gasper freezes the pawns while Koneko kills them and Xenovia kills the rooks. Meanwhile, Rias and Akeno battle the Queen and two Bishops. At Koneko’s suggestion, Rias and Akeno obliterate the enemy forces. The protagonists soon encounter Freed Sellzen, who reincarnated as a Chimeria, a „upgrade” by his new allies in the Khaos Brigade. In a flashback, Diodora encounters Asia and fatally injures himself to make the nun heal him. Aware of Raynare’s plans to take Asia’s Twilight Healing for herself Diodora intends to kill her and revive Asia using one of his Evil Pieces. Back in the present, Kiba finally kills Freed. Diodora reveals that he has already told Asia his history, and intends to sink her further into depression by killing the Occult Research Club in front of her and then raping her. Despite Diodora’s boasts that he comes from the same bloodline as one of the current Satans Ajuka Beelzebub and has consumed one of Ophis’s snakes therefore granting him huge levels of power, Issei uses his Balance Breaker and defeats him. Diodora reveals that the contraption restraining Asia was a creation of a Top tier Longinus user designed to destroy her in the event of his defeat. Issei however uses his Dress Break technique to destroy Asia’s restraints along with her clothes. With Asia safe she requests the chance to pray before they go back. As Asia prays that she will be allowed to stay with Issei forever she disappears.
