Ep. 4: A Strong Enemy Appeared!
Issei’s team locates Freed at an abandoned warehouse, where Kiba’s duel is turned by Valper Galilei until Xenovia and Irina arrive. Freed and Valper escape, prompting a chase interrupted by Rias, Sona, Akeno, and Tsubaki, resulting in punishment for Issei and Saji. Later, the group finds an injured Irina, whom Tsubaki takes to the Sitri residence. Freed reappears with four Excalibur swords, including Irina’s stolen Mimic, and introduces his boss, Kokabiel, a Fallen Angel leader. Kokabiel plans to ignite a Great War by targeting Kuoh Academy Devils to provoke the Satans. After a diversionary attack, Issei’s group returns to school for the impending battle, while Valper and Freed undergo an unknown ceremony inside a magic circle, observed by Kiba and Xenovia.
