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 Gaens 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 didnt get along well. After the group created Yotsugi Ononoki and she chose Kagenui over him as her master theyve been rivals ever since.
