Rose has seven costumes in Castlevania: Belmont’s Curse, and one of them is hidden behind a button sequence Konami fans have known for decades. Entering the Konami Code unlocks the Sonia Style Costume, which dresses Rose as Sonia Belmont, the heroine of the Game Boy spinoff Castlevania Legends. The code takes about five seconds to enter. You can do it at almost any point in the game, and the skin stays on your save once it is unlocked.
Quick answer: In play, enter Up twice, Down twice, then Left, Right, Left, Right, followed by Dodge and Jump. When “New Character Skin Unlocked!” appears, equip the costume via System > Character Skin.
Sonia Belmont skin Konami Code inputs by platform
The eight directional inputs are the same on every platform. The last two presses are your Dodge button and then your Jump button, so the face buttons you press depend on your controller.
| Platform | Directions | Final two inputs |
|---|---|---|
| PlayStation | Give two Up inputs, two Down inputs, then Left, Right, Left, Right. | X, Circle |
| Xbox | Enter Up twice and Down twice, followed in order by Left, Right, Left, Right. | A, B |
| Nintendo Switch | Input Up two times, Down two times, then tap Left, Right, Left, and Right. | B, A |
| PC keyboard | W, W, S, S, A, D, A, D | Shift, Space |
If the sequence doesn’t register, enter it again with the last two buttons swapped. The game wants Dodge followed by Jump, so the order flips if your bindings differ from the defaults. Use the D-pad or keyboard rather than an analog stick, because a stick can drift diagonally and spoil a directional input.
The code does nothing in the demo. It only unlocks the skin in the full game.
How to unlock and equip the Sonia Style Costume
The game doesn’t tie the code to a specific room or story point. You can enter it right after booting up or deep into the castle.
What the Sonia Belmont skin changes
The change is cosmetic only. Rose keeps her stats, weapons, and abilities, and only her appearance changes. That change is large, though. Her orange hair turns blonde, she wears Sonia’s green outfit with brown boots, and her cursed arm is gone. The design is based on Sonia’s original concept art, the same art that appears on the Castlevania Legends cover. The new look is used in cutscenes as well as in combat.
The reference is aimed at longtime fans. Castlevania Legends was meant to show the start of the Belmont clan’s war with Dracula, with Sonia as the first vampire hunter. It was dropped from the official timeline after Lament of Innocence made Leon Belmont the founder of the family. Until Rose arrived, Sonia was the only woman to lead a mainline Castlevania game.
Every Rose skin in Castlevania: Belmont’s Curse
Sonia is one of seven outfits. Four are unlocked by playing the game, and three depend on which version you bought or when you bought it. Every outfit is equipped from the same System > Character Skin menu and stays selected until you change it. That means you can wear a free unlock or a paid costume on the same save.
| Costume | How to unlock | Type |
|---|---|---|
 Rose’s Outfit | Available from the start | Default |
 Sonia Style Costume | Konami Code | Secret |
 Doppelganger Style Costume | Defeat The Self in Notre-Dame | Story |
 Cursed’s Outfit | Reach the bad ending | Story |
 Trevor Style Costume | Midnight Edition | Paid edition |
 Sypha Style Costume | Midnight Edition | Paid edition |
 Alucard Style Costume | Pre-order bonus | Pre-order |
Rose’s Outfit
This is what Rose wears when she arrives in Paris: a long coat and tall boots modeled on the vampire hunters who came before her. It is always available in the Character Skin list, so you can switch back to it at any time.
Doppelganger Style Costume
Beat The Self, Rose’s shadow double, in Notre-Dame. The fight is built around the four virtues, and the costume unlocks in the scene that follows. It is a darker, tattered version of Rose’s usual clothes and is connected to the game’s secret ending.
Cursed’s Outfit
This one requires the bad ending. In Dracula’s Castle, climb the Clock Tower until you reach the Cursed Horologium on the way to Isaac. You need to get there before you have collected every Arcana. When the game asks, choose not to turn back. That locks you into the bad ending, and the curse spreads from Rose’s right arm across her whole body, along with white hair and an animal-skull mask.
Choosing not to turn back at the Cursed Horologium commits your save to the bad ending, so plan that run on purpose.
Trevor and Sypha Style Costumes
Both costumes come with the Midnight Edition, and there is currently no other way to get them. Trevor’s outfit, based on Rose’s father, gives her brown hair and worn hunter gear. Sypha’s outfit, based on her mother, replaces that gear with a sorceress’s purple, gold, and white robes.
The Midnight Edition also includes Family’s Grace, a locket relic that refers to both parents. While it is equipped, the next hit Rose takes is blocked and every enemy nearby is frozen. It then has a 60-second cooldown before it works again.
Alucard Style Costume
The outfit recreates Alucard’s appearance in Symphony of the Night, with flowing white hair and a gold-trimmed black coat. It was available as a pre-order bonus only to players who also completed the demo. The offer has ended, and there is currently no way to obtain the outfit.
You can check whether any costume unlocked by opening System > Character Skin. The Sonia Style Costume confirms itself right away with the banner and chime. The two story costumes show up in the menu after the scene that unlocks them, and every costume in that list can be equipped for the rest of the save.
