Mako Yakumaru

She first appears when Midou Kusabi failed to kill Tsukune. After wounding him with her needle finger, she took control of the doctor, Yutaka Yuji. She then attempted to use him to inject the same substance into Moka. After she smashed a vase to his head, Mako injected the substance into Moka and used her to cut Tsukune before Kurumu intervened. Feeling angry already, Kiria Yoshii told Mako they would work together. She angrily rejected his offer and took control of innocent bystanders in the infirmary, to which Kiria mentioned she has impulse issues. When Tsukune wanted to talk to Moka about the incident, he ran into Mako who used the bystanders to attack him. Moka then intervened before Mako could kill Tsukune. After Tsukune pulled off her Rosario Cross, Moka at first doesn't transform due to the substance Mako used to control her. After Tsukune talks to Moka, Moka jabs herself, transforms, and defeats Mako. (U.S. manga translation called her a "Mongrel" alluding to the mixed heritage of a Monstrel).
