One day, Norman is told by his father, 'I've decided not to expect anything from you anymore,' and is kicked out of his home. This is not surprising, as Norman was completely unable to use magic. However, his fate changes dramatically when he encounters the grimoire 'Goetia.' 'Goetia' is a grimoire that allows the summoning and control of 72 demons. Through this, Norman discovers that while he lacks the aptitude for ordinary magic, he has a unique aptitude for demon summoning. From then on, Norman begins to summon and control demons one after another. With the power of many demons at his command, Norman becomes the strongest. * This novel is also available on Kakuyomu and Alpha.
