Karin Nanase

Karin Nanase appeared to have it all — a thriving idol career and a place at one of Japan's most prestigious universities. But when suspicion surrounding her father's death spiraled into relentless online harassment and media persecution, her world collapsed around her. Seeking refuge from the storm in the quiet city of Makurasaka, she met a sudden and tragic end, crushed beneath steel beams at a construction site. Yet even in death, her story refused to fade. Her image and the rumors that swirled after her passing were deliberately weaponized by Rokka Sakuragawa, who shaped them into the formidable urban legend 'Koutetsu no Nanase.' This haunting phenomenon ultimately stands as the central supernatural case that Kotoko Iwanaga must unravel.
