[3] The anime stares with Erika falling in love with her fake boyfriend, Black Prince Kyoya and must deal with him refusing to accept his feelings for her.

To her dismay, Erika discovers that Kyoya is far more dark-hearted than the "princely" personality he feigns towards others; he frequently gives snarks, insults, and generally has a cynical view of the world.

Kyoya in turn softens and finds out that he is attracted to her as well, something that is cemented when Erika quits being the Wolf Girl after a misunderstanding, which he responds by "promoting" her to become his actual girlfriend.

Erika and Kyoya go through their high school years as a couple while having to face many challenges, including love rivals for each other, misunderstandings, and jealousy.

Near the end of the series, the couple also have to face the truth of a long-distance relationship when Erika has to move to Kyoto to attend a vocational school for glass making; the two ultimately decide on working it out somehow.

Written and illustrated by Ayuko Hatta, Wolf Girl and Black Prince was serialized in Shueisha's Bessatsu Margaret magazine from October 25, 2011, to May 13, 2016.
