Ayaka Kagari, known as the "Princess" of Tougetsu High School, is a fire witch who leads a covert life. Honoka Takamiya, a normal high school student, initially views Ayaka as an unattainable idol. However, when Honoka is attacked by a mysterious witch, Ayaka saves him, revealing her true nature and a secret mission to protect him. This exposure draws Honoka into a conflict between Workshop Witches, who aim to safeguard citizens, and Tower Witches, who seek power hidden within him.
