Tsukina is an average high school girl with a supernatural secret--one that even she is unaware of. After an encounter with a man named Hayate, Tsukina begins to realize she's not entirely human. Her great athletic ability, her enhanced sight at night, even the reason she craves raw meat, all comes down to one answer: She's a werewolf. But this reveal leads her to more questions. Who is she really? What does it mean to be a werewolf? Just where will Tsukina's journey of self discovery lead her?
