Castlevania: River of Rebirth

Once upon a time, the Son of Dracula fell in love with a human. They loved one another until her final breath, and he would mourn her for the centuries to come. Once healed, he found himself attracted to another, who soon found herself reciprocating his feelings. But she too, would perish, before their love could bloom completely.

But just when he had resigned himself to a life of solitude, he found his world shaken by one of the last living descendants of the Belmont Clan. A leading socialite of the British nobility, and an equally skilled vampire hunter, a mutual attraction would explode between them both. But fate is cruel, and only fate could bring them together again, if they were truly destined for a happily ever after.
