You Want Me to Slay the Dragon, but There's a Dragon King Inside Me?

In this world of magic and swords,

dragons are the mightiest rulers,

while humans sit at the bottom of the food chain.

Humans fight for their race and their freedom,

and so a class of people came into being: the best of the best, known as heroes!

A hero's duty is to fight dragons and slay them!

Lyle was one of them. Ranked dead last among the heroes, he accidentally summoned a familiar of his own!

But the result left him stunned. His familiar was none other than the ancient leader of the dragons, the Black Fiend Dragon King?!

Well, would you look at that! Before he even fought a dragon, he had already subdued their boss!

The modern leader of the dragons, the White Spirit Dragon King: "?"
