Firill Crest is a royal daughter of the Duchy of Erlia and one of the rare girls bestowed with the mysterious 'D' ability. Seldom seen without a book in hand, she harbors a quiet dream of becoming a novelist one day. Beneath her composed and refined demeanor, however, lies a playfully cunning streak that delights in teasing those around her. When it comes to her feelings for Yuu Mononobe, she sheds all restraint—pursuing him with a boldness and directness that catches everyone off guard.
