Tadatsuru Teori (手折 正弦, Teori Tadatsuru) is a dollmaster and another Oddity specialist. Similar to Yozuru Kagenui, he specializes in immortal oddities. In particular, he specializes in dead oddities rather than living ones like Kagenui. As a stray specialist, Tadasturu is obsessed with oddities and views them as beautiful creatures and even sometimes captures them for himself. He and Kagenui also both share a curse that prevents either of them from touching the ground.
