被校花拋棄後,從小火龍開始進化

Transformed into a little fire dragon, I thought I was summoned for a sweet romance, only to be torn apart by a dragon core and fed to a bear. On the brink of death, the most popular girl in the academy saves me with a contract. I evolve by swallowing a toad and chase beasts when they charge at us. When my enemies see my dragon form, they kneel in fear: "Is this really the F-rank worthless dragon I ditched?"
