Upon completing the game with the 'good' ending, Julius Mode is unlocked. This allows you to play through the entire game as Julius Belmont, Yoko Belnades, and Alucard. Each character has their own unique abilities and playstyle, offering a fresh perspective on the castle.

- Julius Belmont: Wields the Vampire Killer whip, has sub-weapons (Axe, Holy Water, Cross), and a powerful Grand Cross attack.
- Yoko Belnades: Uses magic spells (Fire, Ice, Lightning) and a healing spell. Her attacks are ranged and elemental.
- Alucard: Transforms into a bat, has a sword, and a powerful Hellfire spell.
In Julius Mode, you cannot use souls, level up, or equip new gear. Your stats are fixed, and you rely solely on the characters' inherent abilities. This mode provides a significant challenge and is a great way to experience the castle with a different combat system. It's a true test of skill and knowledge of the castle layout and enemy patterns.
