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.
I said he was a dark-haired and 
sickly florist's kid named Hanae.
Ich sagte, er ist dunkelhaarig, gerade krank,
das Kind einer Floristin und heißt Hanae.
Dije que se llamaba Hanae,
J’ai parlé de l’enfant d’une fleuriste,
frêle et appelé Hanae.
Eu disse que a pessoa doente era florista
 de cabelos negros e se chamava Hanae.
