Tadatsuru Teori

Tadatsuru Teori was a dollmaster and another Oddity specialist. Similar to Yozuru Kagenui, he specialized in immortal oddities. In particular, he specialized in dead oddities rather than living ones like Kagenui. As a stray specialist, Tadatsuru was obsessed with oddities and viewed them as beautiful creatures and even sometimes captured them for himself.

Tadatsuru was also involved in Izuko Gaen's group in college that included Meme Oshino, Yozuru Kagenui, and Deishuu Kaiki known as the Occult Research Club. Due to their different interests in oddities, Tadatsuru and Kagenui didn't get along well. After the group created Yotsugi Ononoki and she chose Kagenui over him as her master, they've been rivals ever since.
