The Way Of The Dragon Is The Way To Become Strong!

XXXX, a man used and abused for general tasks by his adventuring party, finds himself on the verge of death in dragon territory in the Kugus Mountains after a party member stabs him in the back. Literally. Next time he opens his eyes, he's in the nest of a red dragon named Kaphal whose egg was destroyed in a natural disaster. Having lost both his memories and his name, he turns instead into a young girl named Lushera. And apparently Kaphal plans to raise Lushera as her own daughter…? This is the story of the odd fate binding one dragon and one human, the story of an unconventional mother and daughter.
