Sunflower and Vampire

Ruby awakens to find herself in a tent with Tsukune-tachi (Tsukune with Moka, Yukari, Mizore and Kurumu in convoy) and a soft drink can held to her forehead for her to drink. When asked why she attacked Tsukune-tachi, Ruby explains about how badly witches have been treated and how developers are planning to destroy the sunflower fields where she and her master live. Seeing how kindly Tsukune and his friends treat each other, Ruby starts to have doubts that drive her to later sneak out that night back to her master. When Tsukune-tachi rushes into the sunflower field to search for her, Ruby's denial regarding her master instigates a massive battle at whose climax a forbidden spell is used whose near-irreversibility raises a lot of question of whether Ruby will survive.
