The year is 1450 and a mysterious man made a pact with an evil deity to become immortal and conquer the world. Having become a powerful Demon King, he summoned evil demons from the underworld and sent them out to overthrow the entire European continent. He became known as Count Dracula, and nobody dared to oppose his might.
The Belmont family, a house of nobles living in a remote area of Transylvania, had a young girl with powers not possessed by common folk. Sonia Belmont was looked after by her grandfather who trained her in the use of his special whip that contained magical powers.
One night, when she was 17 years of age, she encountered the young enigmatic Alucard, and formed a bond with him. He was the son of the feared Count, but he had decided to turn away from him and his evil deeds.
The mansion where Sonia was born was one day suddenly attacked by grotesque monsters. When she returned to find her home in ruins she encountered her grandfather breathing his last. Before he passed away, he passed his whip on to her and told Sonia to use her special abilities to rid the land of evil.
Sonia traveled across the Transylvanian countryside to Dracula's Castle, destroyed Dracula's minions, and eventually defeated the Count himself. After having crossed paths with Sonia, Alucard decided to seal himself away before she would press on to face his father, unable to deal with seeing his father dying as well. However, Sonia gave birth to a child not soon after that would continue both his legacy and that of the Belmont Clan.
