Jasper Petrova, the one and only son of the Petrova family, The Petrova family was one of the most known aristocracy in the kingdom of Azerman. Jasper's father, Alfredo Petrova, was also the founder of the famed clan Purgatory's Mark, and Jasper, for his inherent aptitude in Vampiric art and his ability to make a blood bond with a fallen angel at the age of 10, was appointed the clan's youngest Commander.

When Jasper turned 15, it was agreed that he would attend the Royal Academy of Bloodfallen. Jasper, being the conscientious guy that he is, accepted without hesitation and began preparing for his departure, and just before the deadline, his mother arrived with a human girl to offer Jasper as a gift.

"My lord, you may address me as Feriya. I will devote my entire soul to serving you." She murmured to the young Jasper, who was restraining his blood desire, with a smile.

Jasper had no idea that this girl was one of the most cunning persons on the world. Why wouldn't she, given that she is a member of the Astreyana Tribe, which was massacred by some of Azerman's Nobles? Feriya, the last of the tribe, is filled with rage and vows to destroy the kingdom and all vampires inside it.

...

Something dark and horrible was going on on the opposite side of the kingdom.

The organization known as "Vitreous Damian," which claims to be the vampire's original descendants, was scheming to disrupt the Kingdom's calm.

They'll need a vampire with blood powers, which are relatively rare at the moment, and only two persons have the blood ancestral talents: the king of Azerman and Jasper Petrova, the son of the Petrova family and the commander of the Purgatory's Mark.

The issue remains as to what the Virtuous Damians will do.
