How to Redeem Stellar Blade x NIKKE CD Key and Unlock Scarlet’s Outfit

The collaboration between Stellar Blade and GODDESS OF VICTORY: NIKKE gives players access to a limited-edition outfit: Scarlet’s Racer’s High. This costume, styled after Eve’s look in Stellar Blade, comes with custom animations, voice lines, and visual flair but unlocking it isn’t as straightforward as it sounds. Here’s how to get your CD Key and redeem it before time runs out.

What You Need to Be Eligible

You’ll need one of the following to access the NIKKE CD Key:

  • The Complete Edition of Stellar Blade
  • The NIKKE DLC, purchased as part of the Complete Edition

If you bought the base game or added the DLC separately after starting your save, the key won’t be available. The system checks your edition status at the beginning—so late upgrades won’t help.

Where to Find the Code in Stellar Blade

Once you’ve started the game, play through the main story until you reach Xion, about two hours in. That involves progressing through Eidos 7 and defeating the boss Gigas.

After arriving in Xion, look for a glowing orange chest just north of the Hideaway camp. It’s placed near other edition bonus chests (Deluxe, Pre-Order, etc.) and marked with logos from GODDESS OF VICTORY: NIKKE.

When you interact with it:

  • You’ll be prompted to select your NIKKE server.
  • Then, a one-time CD Key will be generated and shown on-screen.

Just make sure to do this before November 12, 2025 (03:00 UTC). After that, the chest will no longer provide codes.

How to Redeem the Code in NIKKE

Once you have your code, head into GODDESS OF VICTORY: NIKKE on your phone or PC and follow these steps:

  1. Tap the bell icon in the upper-right corner of the Lobby screen.
  2. Scroll through the Event Notice section until you find the CD-Key Redemption Portal (or tap the CDK icon, depending on your version).
  3. Paste in your code and hit Confirm.
  4. If all goes well, your reward will be sent straight to your in-game mailbox.

Note: The costume won’t be usable until you clear Stage 2-1 in the campaign, so make sure to progress far enough before checking your inventory.

How to Equip Scarlet’s Racer’s High Outfit

After redemption and meeting the stage requirement, you’ll be able to equip the costume:

  • Open the Nikke menu and select Scarlet.
  • Tap View Mode in the top-left corner.
  • Choose the Racer’s High outfit and press Equip.

The outfit includes its own burst skill cutscene, special standing pose, SD animation, and voiceover set—making it a premium cosmetic in the game.

Redeemed the Code? It Still Won’t Work Without Scarlet

This is a big one, you can’t use the outfit unless you already have Scarlet unlocked.

Scarlet is an SSR unit with a 0.0422% pull rate on regular banners. That means most players will need to rely on limited events or gacha luck (or cash) to get her. Unfortunately, if you don’t have her, the outfit will just sit in your inventory.

Can You Get the Outfit Without the CD Key?

Yes. Scarlet’s Racer’s High costume is also available in the Costume Gacha as part of the crossover event. That said, the CD Key offers a guaranteed way to get it—if you qualify.

If you already pulled the costume through the Gacha, redeeming the CD Key won’t give you a duplicate. There’s no extra reward or compensation.

This crossover is a fun way to bridge two of Shift Up’s most stylish games—but it does come with some fine print. You’ll need to own the right edition, unlock the costume before the deadline, and already have Scarlet to make full use of it.

If you’ve checked all those boxes, the Racer’s High outfit is a sleek addition to your NIKKE lineup. But if not, consider this a reminder that not every cosmetic is just a quick claim away—it’s gated behind a mix of game progress, edition ownership, and gacha luck.
