Despite sharing the same bus each morning and sitting beside one another in class, Ayaka Kagari, the "Princess" of Tougetsu High School, remained an unattainable idol to Honoka Takamiya. The swarm of students adoring the "Princess" was simply an annoyance to Honoka, who lived a lazy, routine high school life. Things appeared perfectly ordinary until, one day, Honoka is suddenly attacked by a mysterious witch. To his astonishment, Ayaka saves his life, disclosing that she is a fire witch on a secret mission to guard Honoka. From that pivotal day, Honoka's mundane existence is upended as he gets caught in the conflict between the Workshop Witches, who aim to shield the populace, and the Tower Witches, who seek to seize a power concealed within him.
