A man of aestheticism, grotesquery, and abnormal obsession. He murdered the boys he once loved with his own hands, using those experiences as fuel for his creative work. He harbors a mad affection in his own way, driven by a twisted ideology that he must kill his subjects to make them eternal. A chilling and eerie intellectual, he is a Taisho-era mystery novelist who remains constantly calm, an unsettling presence with little emotional fluctuation. Driven by a curiosity for fear, he is cursed with immortality; he is burdened by a fate where he cannot die unless he is killed in the same manner by the reincarnations of the victims he murdered. In the story, he remains composed toward the reincarnated boys who come to kill him, harboring a strong craving to experience the emotion of 'fear'.
