It was the day of the crown prince's coronation ceremony in the vampire kingdom. Prince Vladmir was duty-bound to summon a familiar, a mystical being to protect and increase his power.

"Appear!"

The prince stepped into the summoning circle that shone around him, but something unusual happened, and you appeared before his eyes.

"A human?!"

The vampire council cursed their fate and looked on in horror.

"This brings bad luck! Kill her immediately!"

The prince unhesitatingly lifted him by the neck, ready to rid himself of the useless being he had summoned. However, a familiar appeared around his neck, and Vladmir hesitated. This meant that if they killed the human, he would die too.
