Before dying, a magician faces a terrible reality: magic requires more than skills or effort, it also requires a bloodline to support it.
As he watches his executioner using his magic, he ends up accepting his fate and wishes he had all those characteristics to master the magic he loved so much.
Suddenly, he opens his eyes and discovers that he has been reincarnated into the body of a newborn. As Lloyd of Saloum. It turns out that he now has the lineage that he didn’t have in his other life, and as the seventh son in a royal family he doesn’t have to care about anything other than learning.
Lloyd has an innate desire for knowledge, and does not hesitate to escape to read more books in the library, but his caregivers do not let him do as he pleases, especially Sylpha, who trains him rigorously every day.
Sylpha is especially skilled with the sword, and she does not hesitate to use her strength during Lloyd’s training, who uses different spells to fight her, although he tries to hide it so that Sylpha does not notice.
Later, Lloyd hears something new, that there is another library that he has not visited. That inside there are very different magic books, and that even a terrible demon is locked up in one of them.
Lloyd doesn’t care about anything more than getting his hands on those books and he doesn’t hesitate to search for the library. Inside, he discovers a rather complex magical seal, but thanks to his abilities he can enter without being detected.
Excited, he begins to look through some books and immediately listens the demon trying to convince him to free him from his eternal punishment. At first glance, Lloyd ignores it, but his curiosity to learn a new spell grows stronger and he releases it.
The demon tries to betray him, but Lloyd is too strong. In the end, the demon that plagued an entire kingdom ends up defeated by a child, who accepts him as his familiar.
