The day before he begins attending high school, Ashiya Hanae becomes possessed by a strange fuzzy yokai. Being possessed causes him to fall ill, and while spending the start of his high school life repeatedly making trips to the nurse's office, he comes across the contact information of the Mononokean, which specializes in exorcising yokai, and decides to call them. When Ashiya finally visits the Mononokean, he meets the morose master Abeno Haruitsuki.
He's going to curse me to death!
Bestimmt hat es mir
’nen Todesfluch auferlegt.
Me matará con una de sus maldiciones.
C’est sûrement
une malédiction mortelle !
Ele vai me amaldiçoar até eu morrer.
