When Natsume Takashi was adopted by relatives again and taken to the countryside, a monster focused on his grandmother's relics.
When he was about to go to the local high school to apply for admission, he was stopped by a person from the admissions office of the local self-proclaimed "Mono no Monster Academy". According to him, this academy was co-founded by his grandmother, Natsume Reiko, and the students there were all from a class composed of members of the family of slayers who were inextricably linked to monsters or people who could see monsters.
