The official website opened on Monday for the Ao no Exorcist: Kyoto Fujō Ō-hen (Blue Exorcist: Kyoto Impure King Arc) anime series with a teaser video (Note: linked video is region-locked to Japan).
The latest stage play will also adapt the Kyoto Impure King Arc.
In the late Edo Period, a demon known as the Impure King killed thousands of people.
The manga has also inspired several stage plays, the most recent of which will run in Tokyo in August.
