For anyone who doesn't know the premise behind Dracula X, the story picks up where the last Castlevania left off, at the final confrontation between Richter Belmont and that nasty Lord Dracula. Following Dracula's eventual demise, we fast-forward five years into the future, where Richter has gone missing. Mysteriously, the kingdom of Castlevania, which Richter had destroyed, reappears in the mist. Alucard, the son of Dracula, reawakens after a 400-year sleep to destroy, once and for all, his father, Count Dracula.
