The protagonist Hadar was abandoned on a mountain as a sacrifice immediately after birth but was soon picked up and raised by an ancient dragon. Having been raised in a way that combined the best aspects of both dragons and humans, Hadar became the most powerful being, surpassing all other creatures by the age of 12. One day, the ancient dragon told Hadar, “You are human, so you should prepare to live in human society,” and sent him off to the most challenging magic academy.
