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 expressed a mother's joy 
at having a fine son
Ich habe die Freude einer Mutter
über einen wundervollen Sohn …
Te expreso la dicha de tener un hijo
tan maravilloso con este ramo de flores.
Ce bouquet symbolise la joie
d’une mère fière de son fils.
Estou expressando a alegria
 de ter um filho magnífico
