Card Collection

🃏 Card Collection

Kuro AI features a full collectible card system where every character has unique tradeable cards. Earn packs, build your collection, customize your cards with cosmetics, and trade with other users on the marketplace.


Getting Cards

Cards come from card packs, and packs are earned — not sold. Each pack contains one random card. There are two main ways to earn them:

Bond Packs

Interacting with characters earns pack XP. Every 200 XP = 1 free pack.

ActivityXP Earned
Sending a gift1 XP per Krystal spent
Chat photo4 XP (8 with a custom model)
VideoHalf the Krystal price
Chat message1 XP

Gift XP counts for everyone. Chat, photo, and video pack XP require an active membership.

Battle Packs

Winning battles in the Waifu Ranking earns special packs with massively boosted rates:

Rival PackRival victories
Contender PackContender victories

Every card you pull has randomly assigned attributes:

  • Character — which character appears on the card
  • Print Number — your copy number (e.g., #0001, #0042, #3000)
  • Condition — the physical state of the card

Lower print numbers are rarer and more valuable. Print #1 (SP) is the rarest card possible!


Rarity & Print Tiers

A card's rarity is its print tier — the print number determines everything:

TierPrint RangeColorSupply
SP (Single Print)#1 onlyOrangeOnly 1 exists
Legendary#2 – #10GoldOnly 9 copies
Epic#11 – #100Purple90 copies
Rare#101 – #500Blue400 copies
Common#501+GrayUnlimited

SP, Legendary and Epic cards feature special visual effects like holographic shimmer and glowing borders.

The pity system improves your odds over time. If a tier is sold out for a character, the pull gracefully falls to the next tier down.


Card Condition

Each card is assigned a random condition when pulled:

ConditionChance at Pull
Mint10%
Excellent25%
Good40%
Poor20%
Damaged5%

Condition never degrades over time — it only improves if you repair the card.

Condition affects the card's value and what customizations you can apply:

ConditionCustomizations AvailableStardust Value
MintAll (frames, dyes, effects, morphs)100%
ExcellentAll85%
GoodFrames, dyes, effects65%
PoorFrames only40%
DamagedNone20%

You can repair damaged cards using Stardust:

Total (Damaged → Mint)100 SD

Card Variants

Cards come in different seasonal variants with unique artwork:

The same character can have a different card for each variant — collect them all!


Pity System

Kuro AI has a unique relationship-based pity system — and you can watch it work right in the chat's Gift Panel: a row of flames and a heart next to your pack progress.

  • Pack Luck (the flames): your overall luck. The higher it burns, the more often a card you pull gets a rarity upgrade. It grows when you burn cards and when you send gifts — and the part earned by burning resets when you pull a Legendary or SP: your offerings were answered.
  • Hearts: gifts to a character raise her card rarity odds and make her more likely to appear in your packs. Adding her to your wishlist boosts her odds even further.

The more you interact with a character, the better your luck with them. It's a bond thing.


Customizing Cards

You can personalize your cards using Stardust (SD), a currency earned by burning unwanted cards.

Available customizations:

TypeWhat It DoesCost Range
FramesDecorative border around the card50 – 200 SD
DyesColor overlay on background/nameplate30 – 150 SD
EffectsVisual FX (sparkle, fire, holographic, sakura...)100 – 250 SD
GlowsAnimated corner glow effectsVaries
MorphsChange to a seasonal variant artwork300 SD
Fonts & ColorsCustom nameplate text styleVaries

Remember: card condition affects which customizations you can apply. Mint cards get everything, Damaged cards get nothing.


Burning Cards (Stardust)

Don't want a card? Burn it to convert it into Stardust:

Print TierStardust Earned
SP (#1)4,000 SD
Legendary (#2-10)1,000 SD
Epic (#11-100)350 SD
Rare (#101-500)120 SD
Common (#501+)50 SD

The final amount is multiplied by the card's condition (Mint = 100%, Damaged = 20%).

Burning cards also raises your Pack Luck — every burn adds a small boost to your rarity-upgrade odds. The luck earned by burning resets when you pull a Legendary or SP.


Trading on the Market

You can buy and sell cards with other users on the Marketplace:

Selling

  1. Go to the Market and select a card from your inventory
  2. Set your price in Krystals (minimum 100 KR)
  3. List it — the card gets locked until sold or delisted

A 9% marketplace fee is taken from the sale price when your card sells. Listings expire automatically after 15 days if unsold.

Buying

  1. Browse the Market with filters:
    • Character name
    • Print range (#1-10, #11-100, etc.)
    • Condition (Mint, Excellent, etc.)
    • Variant (Original, Seasonal, etc.)
  2. Check the price history chart to see fair pricing
  3. Click Buy to purchase instantly

Making Offers

  • You can also make offers on cards that aren't listed
  • Include Krystals or propose card-for-card trades
  • Both parties must accept for the trade to go through

Tip: Check the "floor price" (cheapest listing) before setting your sell price.
