Reincarnated: Bound as a summoner's pet

{Authors Note: 1 chapter per day, everyday} Once the son of the world's strongest king. Leonardo had all his whims granted at the drop of a hat. Having died at the hands of his younger brother while he slept, he was unaware of his death so it was quite the shock when he found that not only was he no longer the eldest son of the most powerful man to exist, he was now a cute little fox bound to some random commoner girl in a world he doesn't recognize.
