Tokunosuke Terada

Tokunosuke Terada is a seasoned detective at the Makurasaka Police Station and a senior colleague to Saki Yumihara. A former candidate for the Olympic judo team, he carries an imposing physique matched by an equally firm and methodical character. When investigating the urban legend surrounding "Steel Lady Nanase," he refused to entertain anything beyond rational, evidence-based reasoning—a conviction that ultimately led to his tragic death at the hands of the supernatural. His sacrifice proved to be a pivotal turning point, compelling Kotoko Iwanaga to craft an elaborate "fictional theory" designed to dismantle and erase the legend once and for all.
