Originally, he was supposed to be an ordinary child when he was born. Just because he is a descendant of a family of exorcist dragons, just because his parents died early and did not give birth to a daughter as his heir, and just because his aunt accidentally died in the hands of a monster, he must pick up the demon-subduing stick that has been passed down for three thousand years with the help of the family's guardian spirit and start walking on a road full of thorns. In life, many people suddenly appear. No, maybe they shouldn't be people. Time and time again, they broke his life that was supposed to be without surprises.
