The mysterious wolf: a key characteristic in Yukiya's route. It always follows Yukiya around as if monitoring him and is likely to understand the human language. Sigurd's route reveals that the wolf's real name is "Seth". Seth is a magical creature. He is able to speak the human language, and he creates a contract with Yukiya. In exchange for Yukiya's soul, Seth grants him magical powers. The wolf oftentimes mocks Yukiya whenever he says he despises magic. The night Yukya turns into a beast, the wolf tells him it is not easy to break a contract. The contract is forever, and that Yukiya is stuck with him for the rest of his life.
