Otohime "The Manipulator" Yamato is Ouken's granddaughter and a first year student at Tenbi Academy. Her ability is Doll House which allows her to fashion a voodoo doll to manipulate her opponent. Because of her petite appearance, she is mistaken for being younger than her high school age by Haruko. She performs experiments where she manipulates some creatures and people with a chemical that is similar to Ouken's Soul Collector ability. She is one of the four Shishigami who serves Ouken. Also in the beginning Takeru, Inaho, and herself were the only three that couldn't get a reading of their Maken. [Source - MAL AkatsukiUlquiora]
