Asaki Hibana (16), a member of the Hibana family, a prestigious family of exorcists, is a once-in-a-century genius, but because she can see demons that ordinary people cannot, she is regarded as weird by those around her, and she is worried about not being able to make friends. Asaki's grandfather, the current head of the Hibana family, tells her that her condition for quitting as an exorcist is to capture the Hibana family's sworn enemy, the Yatagarasu clan. While Asaki is struggling to find Yatagarasu, a mysterious transfer student, Amahara Ten, appears in front of Asaki and suddenly kisses her hand and says, "I am Yatagarasu, the crow whose life you saved."
