In essence, the story revolves around a dragon named Lindabrea who belongs to a noble family. She's not content with just eating orc meat and decides to leave her castle in search of more delectable cuisine. Accompanying her is Carmilla, her vampire maid whom she considers "useless" but values for her loyalty. Joanna sees Lindabrea as a rival due to jealousy over how easily she seems to win battles while Joanna struggles and trains diligently. However, Lindabrea often appears uninterested in Joanna's conversations, usually preoccupied with food. Since her name is difficult to pronounce, Genzou nicknames her "Hanako".
