Beating the previous Vampire King, Saruth is quite a feat for Calidora.
Considering that he's her father, it's commendable.
Rex remembered that it hadn't been that long from his first encounter with Calidora, and back then, she was guarded by two Royal Vampire Guards. She was no more than a mere third-rank realm, having guards beside her is a must as the Vampire Princess.
Now, she went anywhere alone and even possessed her own castle.
Her growth could be seen evidently.
"Go easy on your parents. In time, you will be stronger than them, so cut them some slack" Rex mused with a shake of his head, had his parents been alive, he would've pampered them with the entire world.
Maybe, he would even turn them into Werewolves, to help them survive better.
Alas, that was all too late.
