Even though they shared the same bus every morning and sat next to each other in class, Ayaka Kagari, the "Princess" of Tougetsu High School, was nothing more than an unreachable idol for Honoka Takamiya. The horde of students who worshipped the "Princess" was merely a nuisance to Honoka, living his lazy, regular high school life. Everything seemed perfectly normal until, one day, Honoka is attacked out of the blue by a mysterious witch. To his surprise, Ayaka saves his life, revealing herself to be a fire witch on a covert mission to protect Honoka. From that fateful day, the ordinary life of Honoka is turned upside down as he is thrown into the war between the Workshop Witches, who strive to protect the citizens, and the Tower Witches, who desire to steal a power hidden within him.

In Japanese folklore, a "tsukumogami" is an object that has gained a soul, becoming alive and self-aware. There are two types of tsukumogami: the mature "tsugumomo," who have developed through long years of harmony with their owners, and the aberrant "amasogi," premature spirits that are only born to grant the destructive wishes of certain people. Kazuya Kagami has never gone without his mother's obi after her death. Be it at home or school, he keeps it safe with him at all times. One day, he nearly loses his life when a wig amasogi attacks him. When all seems to be over, his treasured obi defends him, transforming into a beautiful girl. She introduces herself as Kiriha, a tsugumomo owned by Kazuya's mother. With Kiriha's arrival, Kazuya enters a reality he has never seen before, a world with gods and tsukumogami.
