Other than the kids, their parents, the secretary girl (?), and the fox girl, all I’m seeing is the MC getting dragged into things that have nothing to do with him. He’s basically treated like the black sheep, literally used to save those divinities from an ass misunderstanding war with the yokai.

Is this novel adaptation? If so, can any novel readers tell me if there's any "justification" for mc's mother abandonment? Will these misunderstanding settle down?
