Gacha Rules and Guidelines

Last updated: 11/12/2026

Gacha Rules:

Please read the following carefully before buying a Gacha listing. Placing an order for a Gacha listing means you agree to follow these rules.
The Gacha transaction fee rate is 3.2%

1. Gacha listings

A Gacha listing is set up by the seller with "prizes" and a "price per draw". Each Gacha has at least 2 prizes; every prize is linked to at least one item card and has its own stock.
The number of draws a buyer can purchase = the remaining stock of all prizes − the draws already reserved by other orders awaiting payment. An order cannot exceed this limit.

2. Public listings only

Gacha listings are always public and cannot be set as private listings.

3. In-stock only, real photos and shipping time

Gacha listings are for in-stock merch only. Pre-order merch, proxy-purchase merch, merch that has not yet arrived, or merch that cannot be shipped immediately may not be listed.
The seller must upload complete real photos of every prize. Cropped photos from others, official images, and item card images are not allowed.
The seller must ship within 7 days after the draw results are published.

4. No bundling or extra charges

Sellers may not, under any name, require buyers to bundle other merch, pay a price difference, or pay anything beyond the price of the draws. This includes requests made in the listing description, in chat, or before shipping. A necessary packaging fee that the shop sets separately is not included in this ban.

Gacha listings that break rules 3 or 4 will be delisted by the moderators or the platform.

5. Draw mechanism (drawn when the order is confirmed)

When you place an order, the system first reserves the draws you purchased.

• Credit card / bank transfer: the system draws randomly the moment the payment succeeds.
• Cash on delivery (available only if the seller has enabled it): the draw happens when the order is automatically confirmed.

Draws are uniformly random, weighted by each prize's remaining stock. Each prize drawn is deducted from that prize's stock. The draw results are shown in the order.

6. Draw results and order cancellation

Once the draw results are published, neither the buyer nor the seller can cancel the order directly. The buyer may still "request cancellation" through the regular order flow, and the seller decides whether to accept.
The seller must ship according to the draw results.

Gacha order cancellation rules
Make sure the listing information is accurate. If there is any undisclosed damage beyond normal factory defects, a bundling error, a wrong item card selection, or a similar issue, the buyer has the right to request cancellation of the order, and the seller may not refuse.

7. Unpaid orders

The payment deadline for an unpaid order is the same as for regular orders (about 15 minutes for credit card; bank transfer follows its payment deadline). Expired orders are automatically voided and the reserved draws are released. No suspension is applied, and it does not count toward the abandonment rate.

8. Platform fee

The Gacha transaction fee rate in Taiwan is 3.2%.

9. Seller editing and delisting restrictions

Once any buyer has placed an order (including orders awaiting payment), the seller can no longer edit the prizes, price, or listing content.
While an order awaiting payment is holding reserved draws, the listing cannot be delisted or deleted.
To add a grand prize or change the content, delist the listing and create a new Gacha listing.

10. Other matters

Shipping fees, returns, and dispute handling follow KOCA's general transaction rules.
