The protagonist Boji is the eldest son of King Perth and the apprentice of Despa. Boji was born of King Perth and the first giant wife, so Boji is a pure-blooded giant, his stomach is stronger than ordinary people and has a very high resistance to poison.
However, because King Perth made a contract with the demon god when he was young, in order to allow King Perth to obtain the unparalleled force in the world, he took away Boji's original giant power, resulting in Boji being extremely short at birth, and deaf in both ears. So Boji has no muscle strength at all.
He is prone to shyness and lack of self-confidence, but when he sees others in trouble, he always wants to step up to help out desperately, and has a gentle heart that doesn't give up easily. Because of his short stature and his inability to hear, Boji was ridiculed by the people. Although Boji always greeted people with a smile, he would still cry in private.
Even though his arms have no strength at all, Boji has a superb ability to dodge attacks, and after receiving Despa's training, he learned how to target weak spots. According to Despa, Boji is basically unbeatable, even Desha, the king of the underworld, can be defeated.
