In a world that is full of beast tamers, Samuel who lives with his sole parent, his father, is faced with a crisis when their village is attacked.
It's on this occasion that he finds out that his father was also a beast tamer. But his strength was not capable of dealing with the beast that had attacked.
His beast is killed and he suffers a backlash that leads to him being bedridden. As for the beast that attacked, it retreated after killing almost all the villagers.
During his father's dying moments, he reveals that Samuel held a deep power within him and that he should go out and explore it. They had hidden in that village for over 18 years, to avoid the exploitation of his talent.
As he finally leaves the village for the first time as long as he could remember, he finally ventures into the world, with a big secret hidden within him.

The Ancient Beast Tamer Bloodline

Samuel was so shocked by this. He had not anticipated that something like this was going to happen. According to the information that he had, the moment that he tried forming a contract with another beast, the formless energy within his body was supposed to come and get out of his body through his hand.

After that, it would enter into the body of the monster through its orifices. And after that, it would enter into the mind of the monster, before finally establishing a seal within the mind of the monster, which would make it subservient to him.

Even though all the information that he had was just rumors from a few people from the website, regardless, at least they possessed quite some information about what supposed to be done.
