Cinderella Glass Curtsy Costume is the headline popularity-poll reward attached to NIKKE’s October Halloween update, giving Cinderella a limited cosmetic treatment with more production work than a basic recolour. The outfit sits inside its own Cinderella Special rather than being folded into the normal Costume Shop flow, which is why players can easily confuse it with a paid seasonal skin or Costume Gacha release. The event also bundles several Cinderella-themed extras alongside the outfit, making the claim route worth checking even for players who rarely spend on cosmetics.
The presentation around Cinderella Glass Curtsy Costume is unusually generous for a poll reward because SHIFT UP has confirmed full voice-over support, a Burst Skill animation, a standing pose and a special SD model. The same Special also includes music and avatar-frame rewards tied to the popularity poll results. That combination makes this more than a single wardrobe unlock, and it is important to use the correct event screen so none of the accompanying rewards are missed during the longer claim window.
How to Get Cinderella Glass Curtsy Costume Free

To get the Cinderella Glass Curtsy Costume, log in during Cinderella Special after the October 8 maintenance and claim the event reward from the Special while it is available. SHIFT UP explicitly lists Glass Curtsy as the popularity-poll winner costume distributed through this event, so you do not need to buy Costume Gacha pulls or purchase a premium pass to receive it.
The Cinderella Special is scheduled to remain available until December 3, 2026 at 04:59:59 UTC+9. That gives the Cinderella Glass Curtsy Costume a much longer claim window than the Little Witch Trick Halloween story event, which ends in late October. Even so, claiming it early removes the risk of forgetting about the Special after the rest of the Halloween content rotates out.
Is Cinderella Glass Curtsy Costume Really Free?
Yes. The Cinderella Glass Curtsy Costume is a free login reward from Cinderella Special. It is not described as a Costume Gacha prize, Cash Shop rerun or Mission Pass reward in the official October 8 update notice. The distinction matters because NIKKE is running other paid costume content during the same patch, including Label’s Occultist outfit through the premium OCCULTIST PASS.
Glass Curtsy comes from a different route. The Cinderella Glass Curtsy Costume celebrates Cinderella winning the 2026 NIKKE popularity poll, and the event notice thanks Commanders before listing the costume and other poll rewards. If a shop screen asks for paid currency, you are looking at a different October cosmetic rather than the Cinderella Special claim.
What Comes With the Cinderella Glass Curtsy Costume?
The Cinderella Glass Curtsy Costume includes a full voice-over, a dedicated Burst Skill animation, a standing pose and a special SD model. Those features are specifically confirmed in the official patch notes and distinguish Glass Curtsy from simpler costumes that only change the character’s normal appearance.
The reward bundle around the Cinderella Glass Curtsy Costume also includes Cinderella’s theme song, Beautiful Me. The song is part of Cinderella Special rather than an additional costume purchase. Claim the full Special reward set rather than stopping after the outfit appears in the wardrobe, because the event is designed to distribute several popularity-poll celebration items together.
Which Avatar Frames Are Included?
Cinderella Special also awards limited avatar frames for the top five winners of the Doki Doki IV popularity poll. The named characters are Cinderella, Liberalio, Little Mermaid, Arcana: Fortune Mate and Snow White: Heavy Arms. These frames are separate rewards from the Cinderella Glass Curtsy Costume, but they are distributed through the same Special.
This is useful if you mainly opened the event to collect the Cinderella Glass Curtsy Costume. Do not assume the outfit is the only item worth claiming. Check the complete Cinderella Special reward presentation so the theme song and the five poll frames are collected alongside the costume while the event remains active.
Where Do You Equip Glass Curtsy?
After claiming the Cinderella Glass Curtsy Costume, use Cinderella’s character and costume options to select Glass Curtsy as her active appearance. The exact button placement can vary slightly with NIKKE’s interface layout, but the outfit belongs to Cinderella and is not a separate playable Nikke or alternate banner character.
That means the Cinderella Glass Curtsy Costume does not replace your existing Cinderella investment. It changes her presentation while keeping the same character progression. The special Burst animation, voice work, standing pose and SD model activate as part of the costume package rather than requiring you to build a second Cinderella from zero.
Do You Need Cinderella Before Claiming the Costume?
The official October 8 notice describes the Cinderella Glass Curtsy Costume as a login reward in Cinderella Special and does not state that you must already own Cinderella to claim the event reward. The safest approach is therefore to claim the costume during the event window even if Cinderella is not currently in your roster, rather than ignoring a limited reward because you cannot equip it immediately.
Ownership rules for equipping a costume are separate from the event claim itself. Once you have Glass Curtsy on the account, it can be used with Cinderella when the character is available to you. The important limited-time action is securing the Special reward before the December deadline.
When Does the Free Cinderella Costume End?
The Cinderella Glass Curtsy Costume claim period runs from the end of the October 8 maintenance until December 3, 2026 at 04:59:59 UTC+9. That is considerably longer than the Halloween story event and Belorta’s Special Recruit window, so the costume will still be claimable after Little Witch Trick ends.
There is still no reason to leave the Cinderella Glass Curtsy Costume until the final day. Open Cinderella Special after the update, claim Glass Curtsy and the associated poll rewards, then verify the outfit is registered to your account. That turns one of the cleanest free rewards in the October update into a quick claim instead of a deadline risk later in the season.
