Episode Title:
The Millennial Dream - Melancholic Misanthrope.
Episode Description:
While Benio recuperates from her injuries, Arima reveals to Seigen that during his fight with Kuranashi, he triggered a special spell that separated his body and soul temporarily, allowing him to witness events from the past. In the occasion, he discovered that Abe no Seimei created Magano as a place to banish humanity's residual Yin energy to, but its accumulation gave birth to stronger impurities, like the Basara, later establishing the Twelve Guardians and founding the Exorcist Union to deal with them. However, Arima confides to Rokuro that knowing it was just a temporary solution, Seimei set in motion the events that led to the advent of the Twin Stars, while creating the strongest impurity, the "Cataclysm King", to wipe out humanity should they become a threat to the world, who is none other than Rokuro himself. Arima also explains in order to get rid of the Yin energy stored in his body and become fully human, Rokuro must conceive with Benio a child, the Miko, that will inherit Benio's massive Yang energy to balance itself. In doubt about what he should do, Rokuro returns home and meets Suzu, who instead of fighting him, suggests him to follow his own heart before leaving. Later at night, when Rokuro is out shopping, he is once again approached by Yūto, who threatens to destroy the entire world with his powers should Rokuro take too long to come after him and makes his leave.
