Aoi Tanio

Aoi Tanio is a woman who murdered her boyfriend and concealed his body deep in the mountains. Her unsettling behavior caught the attention of the local deity known as the 'Great Serpent,' who then enlisted Kotoko Iwanaga to unravel the mystery surrounding her actions. Though she appeared outwardly calm and confessed without hesitation upon arrest, a devastating secret lay beneath the surface: after taking her lover's life, she discovered she was pregnant—only to suffer a miscarriage shortly after. This cruel sequence of events left her soul fractured by grief and irreconcilable inner turmoil.
