Born into a dirt poor mining family, Karl only had one chance to get ahead in life, the annual elite recruitment day. On their final day of middle school, every student in the Golden Dragon Nation was given an experimental injection to awaken their affinity with magic.

Those few who succeeded would become the Elite, the leaders and idols of the nation, blessed with incredible magical powers and respected by all. Those who did not would return to their normal lives of hard work and low wages, just doing the best they could.

But with the nation surrounded by enemies, both humans and monsters, how long would these peaceful days of magical idols last?

Follow the story of Karl as he awakens a unique power and strives to become the world's first Legendary Beast Master.
