As the Hero’s Mother, I Became an Executive of the Demon King’s Army

I lost my husband in an accident two years ago and became a single mother, and one day I was summoned to another world with my son. The humans who summoned us called my son a hero and wanted him to fight the resurrected Demon King. It's ridiculous to have my son, who is in still his first year of junior high, fight against monsters!Strongly opposing this, I was treated as an obstacle and left alone in a monster's den. Though I was powerless and already resigned myself to death, it was the demons, who were supposed to be enemies of humans, who saved me. As I spent time together with them, my feelings for the demons grew, but peaceful days do not last long. The only weapons I had to resist against the numerous challenges that faced me were my cooking abilities and my quick wit."I won't die until I meet my son!" Laboring away with this thought in mind, I had become one of the upper echelons of the demon king's army before I knew it
