Monster parents-a neologism that denotes parents who repeatedly make unreasonable demands to their children’s school and prevent it from functioning normally.

Takamura Itsuki is the ace lawyer of a major law firm. One day, she is assigned on a case requested by a school board, and learns of the existence of "monster parents." She meets a parent who wants the school to fire a teacher with a dialect for fear that he may exert bad influence on her child, a parent who insists that her son get a regular position on the soccer team, a parent who refuses to pay the lunch fee because it doesn’t taste good and so on. She is, at first, reluctant about this case, but gradually becomes determined to solve the problems.
