Get all of the Dracula relics and go to Castle B. Equip both the JB and MK Bracelets. Go down into the room and you will start fighting Maxim after talking to him. Defeat Maxim and all the Dracula relics will start flying around and Dracula Wraith will appear. When the battle starts, enter the pause menu and go to "Relics". You will see that you still have all of the Dracula relics, even though they flew away and made Dracula.
