Igni comes from a noble family that seeks to be the most powerful. On his twelfth birthday, during a ceremony called the "Rite of Appropriateness," it is discovered that he can only cast fireball, a basic spell. Because of this, he is cast out of his family's home. He struggles in the town, facing hardship, until he meets his grandfather, once known as the "Pole" and among the strongest. This reunion sets events in motion. The story is a school-based magic fantasy about a boy who becomes the strongest simply because he wanted to gain popularity.
