Episode Title:
The Couple Alone - Lonely Twin Exorcists.
Episode Description:
As Rokuro and Yūto begin fighting, Seigen meets Arima and reveals his intention to assist Rokuro, but Arima dissuades him, affirming that with the Twelve Guardians and most of the other exorcists out of commission, Rokuro is the only one that can stand against Yūto. Meanwhile, Benio is in turmoil following Rokuro's sudden decision to break up their partnership, and her friends attempt to cheer her up. Yūto easily overpowers Rokuro, who then questions him about his true motivations. Yūto then responds that at that point, the only thing that matters to him is fighting with Rokuro, who then decides to unlock his impurity powers, hoping that if he goes out of control and transforms into the Cataclysm King, the curse Arima placed in his heart at his request will kill him.
