Monsters lurk in every corner of the world. They work, they study and they live.
In Echidna's School for Little Monsters, young monsters learn about the world around them and prepare for adulthood. It is one of the few local schools in the city and it needs more teachers.
Class 5C is an average class of monsters facing the worst disaster any little monster has ever faced in school: being held back for a year. Their previous teachers have left them way behind in their studies. Anyone who doesn't meet the required minimum grades will be held back, a devastating blow to the souls of 11-to-13-year-old kids.
Enter Caragh Dullahan, a new temporary teacher who comes highly recommended for her ability to swoop in and lead troubled classes to victory. Hopefully, the students of Class 5C will be saved from a situation not born of their own actions. It would be unfair for them to be punished for it.
Caragh Dullahan, well-known expert in helping troubled students, is currently facing a crisis of her own; she's sick of constantly moving around. She may have forged a career but she has no home. When she takes the job at Echidna's School for Little Monsters, she finally sees her chance to have a stable life among its many inhabitants. What will she find in her quest? A place to belong to? Love? Friendship? Or will she be back on the road in a month?
