Ura Toukyou no Osoroshidokoro

Synopsis:

Under Tokyo exists "Ura-Tokyo," a hidden parallel to the metropolis we are familiar with. In this realm, a clandestine school educates exorcists to confront malevolent entities. Upon stepping into the prohibited area of Madara Shirazunomori Forest, Soma Kuroniwa becomes afflicted with a curse that binds him to a particularly perilous spirit. Concealing his authentic self, he joins the academy and immerses himself in its harsh training regimen—one that only a small fraction of participants manage to complete. As a formidable spirit approaches, the unnatural power slumbering within him stirs into activity.
