Shuzen, Kokoa

朱染心愛

Kokoa Shuzen is the younger half-sister of Moka Akashiya, the sister of Karua Shuzen, and the stepsister of Akua Shuzen. She resembles Moka, sharing her green eyes, but differs with her orange hair and her "uncool" vampire demeanor. She arrives as a first-year student at Yokai Academy during the second serialization and anime adaptation. Like her sister, Kokoa is a vampire, but her powers are not sealed, and she does not possess the same level of supernatural strength as Moka. To compensate, she has a pet bat named Kou that can transform into various weapons, which she wields with enough strength to make herself formidable.
Kokoa despises Moka for sealing away her inner personality, whom she adores and loves. Before Moka left to study at the academy and prior to receiving the rosario, the sisters often clashed, although Kokoa could never defeat Moka in a duel. She constantly attacks Moka, hoping to draw out the "Inner Moka," and feels angry that Tsukune has the ability to unlock Moka's true nature. She begrudgingly accepts the presence of her sealed sister, though this eventually softens to simply accepting both Mokas as her sister. Unlike Moka, Kokoa harbors a deep-seated fear of their older sister, Kalua Shuzen. Known as the kindest among their family, Kalua continuously babies Kokoa and has a "smile of an angel," which frightens Kokoa because she is somewhat insane.

Spoiler

As a parallel to her sisters, Kokoa's name may be an intended pun on the word "cocoa".
