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.
Now that I'm in high school as of tomorrow,
Morgen fängt endlich

Ahora que comenzaré

Dire que ma vie de lycéen
commence enfin demain…
Agora que estou no ensino médio
