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.
Are you having fun teasing me 
while I desperately beg for help?!
Bereitet es Ihnen Freude, mich zu ärgern,
während ich verzweifelt um Hilfe bettle?
¿Te burlarás de mí
aunque te pedí ayuda?
C’est bon,
vous vous êtes bien amusé ?
É divertido me provocar 
enquanto eu imploro por ajuda?
