Ele foi sobrevivente de uma tragédia e agora quer apenas levar uma vida pacata, até que uma menina aparece diante dele e o leva de volta àquilo de que ele tanto fugiu.

Depois do encontro de Rokuro com Benio, os dois se desentendem e tomam caminhos distintos, mas parece que os caminhos voltam a se cruzar em pouco tempo.

Subaru of the Twelve Guardians thinks that Benio and Rokuro need to understand each other better, but the Twin Star Exorcists aren't convinced and insist on conventional combat training.

Seigen resolves to blow himself up; however, Rokuro and Benio escape from inside the barrier, which again Yuuto congratulates. Seigen is saved minus one arm and Rokuro manages to land a punch on Yuuto who is shocked. He then announces that he will wait for Rokuro's answer (whether he will join Yuuto on the dark side) at a place where there are precious memories for the both of them: Hiinatsuki Dormitory. Seigen and Mayura were hospitalized: Seigen undergoing surgery and Mayura still unconscious. Jissama has received information that the Twelve Guardians has been mobilized to destroy Yuuto and he gives Rokuro a package that Seigen had been wanting to give him. Inside, there is the black exorcist uniform that Seigen wore. Rokuro wears the uniform and announces to Benio that he will defeat Yuuto even with the Twelve Guardians mobilized.
