A new religious movement has taken root in Saya's town. Its founder, Amamiya Otoha — called Tamayori-hime for her ability to speak with gods — has attracted serious attention. Saya assumes her ordinary life will continue as it always has. Then a classmate dies. That is only the beginning. Saya is told that she too is Tamayori-hime, guardians appear in front of her, and a role she never knew existed starts pulling her in.
