Mako Yakumaru(薬丸 麻子, Yakumaru Mako) is a character from Rosario + Vampire and a member of the ANTI-THESIS.
Manga
Year One
She first appears when Midou Kusabi failed to kill Tsukune. After wounding him with her needle finger, she took control of the doctor. 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, she jabs herself, transforms, and defeats Mako. (U.S. manga translation called her a "Mongrel" alluding to the mixed heritage of a Monstrel)
Year Two
In Alucard's return, Mako reappears along side with Midou defeating one of Alucard's clones in the final battle.
Anime

After Mako is defeated, Yukari returns to her old self again.
Powers and Abilities
Powers
Hybrid Physiology: Due to the mixed breeding of her ancestry, Mako Yakumaru has no definite yokai traits rather it's a mixed form of all the yokai species in her bloodline though she has not shown her true form.
- Transformation: The main ability for all monstrel where Mako only transforms her finger into an elongated needle rather her entire body unlike most monstrel.
- Mind Control Fluid Secretion: Through her transformed needle finger, Mako injects a special fluid into her victims that places them under her direct control where even a yokai as powerful as a vampire like Moka was affected. Though it should be noted she was only able to this while Moka was sealed and eventually she mustered the strength to resist the control fluid altogether.
Abilities
Expert Strategist & Tactician: Mako is a skilled tactician as she planned to destroy the Newspaper Club and more specifically Tsukune while they were vulnerable within the hospital through the use of her special fluid that placed all of the individuals under her control so nobody would help them. She even took advantage of Tsukune's trust towards Moka to have the vampire personally kill him.
