Two laborotory-assistants, Zen Amako, Shuichi Aiga and their daughters boss Shoko Yobuno are connected with the triangle edged sacred animal mirror. They are also pure-blooded demons and siblings off each other, allthough they are unaware off these facts. This mirror will connect with two pure-blooded male demons.
