|“||Here comes the pain!||„|
|~ Kokoa Shuzen|
She is voiced by Chiwa Saito in the Japanese version of the anime and Kira Vincent-Davis in the English version, the former of whom also voices Homura Akemi.
Bearing a similar appearance to Moka, except for her flaming orange red hair (though it is stated she dyes her hair this colour) and green eyes, she arrives as a first-year student to Yōkai Academy. Like her sister, Kokoa is also a vampire, but her powers are not sealed and does not carry the same supernatural strength Moka possesses, supposedley because she was still young. To compensate, she has a pet bat, Kou (Nazo Koumori in the anime), that can transform into a variety of weapons and wields it with enough strength to make herself formidable.
