Atsushi Hirata

Atsushi Hirata is Tarou's new counselor and therapist. An eccentric clinical psychologist from Tokyo University, he introduces much of the series' psychological terminology and is apparently interested in Tarou's dreams and condition as a means supporting his own theories. Initially, he does not believe Tarou's O.B.Es. are in any way supernatural and attributes these moments as states of altered consciousness. He later begins to admit that there may be a supernatural component and that the land around the mountain in question may be the trigger of these events. He has also experienced supernatural events during the series but prefers to keep them private, as they fit the diagnostics for certain psychological alterations.
