OP-10 Royal Blood Guide: Secret Rares, Special Cards and Japanese Box Contents

The OP-10 (OP10) Secret Rare slot is small: the official Royal Blood page lists Secret Rare 2 and Special Card 6 in the set’s rarity breakdown. This guide explains what the official pages say about the OP10 Secret Rare and Special Card slots, how the two official sites differ, and what the Japanese edition box contains.

Updated November 10, 2026

What is the OP10 Secret Rare slot in Royal Blood?

The OP10 Secret Rare slot is two cards in the whole set. The official English product page and the Asia-English page both give the same figure: Secret Rare 2.

That number is the full Secret Rare count, not a count per box and not a rate. It tells you how many different Secret Rare card types exist in OP-10. If you are deciding whether to chase an OP10 Secret Rare, the count is the firm number in the rarity breakdown: two card types, out of a set the Asia-English page describes as 125+1 types.

The official English page shows card numbers for some cards but no names for them. So this guide does not attach a name to either Secret Rare. Where a name is confirmed by an official source, it is stated; where only a number is given, only the number is used.

How many Special Cards and other rare slots does OP-10 have?

OP-10 has 6 Special Cards, and the full official rarity breakdown runs from Common (45) down to Secret Rare (2). The table below sets out both official pages side by side so you can see every slot.

Adding the English-site rows gives 127 (6 + 45 + 30 + 26 + 10 + 2 + 6 + 1 + 1), which matches 126+1. Adding the Asia-English rows gives 126 (the same list without the Treasure Rare), which matches 125+1. The two official counts are therefore consistent with their own breakdowns.

The rare end of the set, meaning Super Rare, Secret Rare, Special Card and Treasure Rare, covers 10 + 2 + 6 + 1 = 19 card types on the English-site page. On the Asia-English page it covers 18, because no Treasure Rare is listed. Those are sums of the official rows, not separate official figures.

Why do the official OP-10 pages show 126+1 and 125+1 card types?

The two totals differ by exactly one slot, the Treasure Rare, which only the English-site page lists. Every other row in the rarity breakdown is identical between the two pages.

The pages also give different release dates. The Asia-English page gives November 30, 2024, which is the Japanese release date shown on the official Japanese announcement, published November 22, 2024. The English-site page gives March 21, 2025 and a price of USD $4.99 per pack. The Japanese announcement gives 220 yen including tax per pack.

For a buyer of the Japanese edition, the practical reading is simple. The Japanese edition is the November 30, 2024 product. If you compare it against the English-site page for the set, expect that page to include the Treasure Rare line, and expect the dates to be months apart. Our OP-10 Royal Blood Japanese One Piece Booster Box (update: currently sold out — restock requests via Quick Order) page lists the Japanese release date as November 30, 2024 and 125 card types.

Which OP-10 cards do the official pages name?

The English official page names no cards, only card numbers, while the Japanese release page names one: the Super Parallel Trafalgar Law. Everything else below is a number with the role the page gives it.

These nine numbers are the ones shown on the official English page. The page presents them as examples of the set’s new theme, its support cards and its new leaders. It does not say they are Secret Rares or Special Cards, and this guide does not say so either. The official page also notes that illustrations may differ somewhat from the final product.

The shop page for the box names four characters as chase cards: Nefertari Vivi, Vinsmoke Reiju, Sabo and Donquixote Doflamingo, along with alt-art royal-themed chase cards.

What does the Japanese release page say about Super Parallel cards?

The Japanese release page names exactly one Super Parallel card: Trafalgar Law (written トラファルガー・ロー). The official announcement uses the rarity name スーパーパラレル (Super Parallel) for this card.

The same page says the set features many characters from the Punk Hazard and Dressrosa arcs, and that the popular Supernova theme is significantly strengthened. It states that the full card list is on the official site.

The page does not say how many Super Parallel cards exist, and it does not say whether the Super Parallel sits inside the Secret Rare count, the Special Card count or elsewhere. So the safe reading is this: Super Parallel is a rarity name used in the Japanese announcement, Trafalgar Law is the one card it names, and the English rarity table above is a separate official list with its own labels. Do not add the two lists together, and do not assume a one-to-one match between a Japanese rarity name and an English slot.

What does a Japanese OP-10 box contain?

A Japanese OP-10 Royal Blood box contains 24 booster packs with 6 cards per pack, which is 144 cards. Our OP-10 booster box page (update: currently sold out — restock requests via Quick Order) gives the contents as follows.

The pack figure of 6 cards matches the Asia-English page, which gives the configuration as 1 pack: 6 cards. The box is a sealed, randomized product. The page states that cards are randomly packed at the factory and that individual card pulls are not guaranteed. The official pages add that multiples of one card may appear and that a full set may be hard to assemble.

That last point matters for anyone buying a box for the rare slots. With 144 cards in a box and only 2 Secret Rare card types in the set, a box is a random draw, and the product page states that individual card pulls are not guaranteed.

Does PRB-02 reprint OP-10 cards?

PRB-02 ONE PIECE CARD THE BEST vol.2 features top cards from OP-07 through OP-10, so OP-10 is one of the four sets it draws from. The shop page describes it as the second premium best-of collection, with new premium artwork and special parallel treatments.

The details on the PRB-02 Japanese booster box page (update: currently sold out — restock requests via Quick Order) are different from OP-10: 10 booster packs per box, 10 cards per pack (100 cards per box), 179 card types, and a Japanese release date of October 3, 2025. The page lists Leaders, Commons, Uncommons, Rares, Super Rares and Secret Rares with alternate-art parallels, plus new DON!! card designs and gold-stamped parallels.

The page does not list which OP-10 cards appear in PRB-02, so this guide does not say whether either OP-10 Secret Rare is among them. If you want the Royal Blood set itself, buy OP-10. If you want a mixed best-of product that touches OP-07 through OP-10, PRB-02 is a separate product with its own card list.

Should I buy the regular OP-10 box or the damaged box?

Buy the regular box if the outer box matters to you, and the damaged box if you plan to open it. Both are OP-10 Royal Blood Japanese booster boxes, and the damaged version is discounted for cosmetic damage to the outer box.

The OP-10 Royal Blood damaged box page says the box is discounted because of dents, creases, scuffs or scratches on the outer box, and that the cards inside are unaffected. It also sets firm terms:

• Photos are samples, and the box you receive may look different from them.
• The type and extent of damage vary by item.
• The item is sold as-is, with no inquiries answered about it, and returns and refunds are not accepted.

Because the rare slots are inside the packs, outer-box damage does not change the set’s Secret Rare or Special Card counts. A collector who wants to display a sealed box should pick the regular one. Someone who simply wants to open packs can take the damaged version and accept the as-is terms. The photos below show sample condition for this product.

Which OP-10 product fits which buyer?

Choose the regular OP-10 box for a clean sealed display, the damaged OP-10 box for opening packs at a lower price, and PRB-02 only if you want a best-of mix instead of the Royal Blood set. The table compares the three on facts from the product pages.

Royal Blood is built around the royal bloodlines of the One Piece world, from the Nefertari family to the Vinsmoke family and the Donquixote dynasty, according to the product page. The official pages add the Punk Hazard theme and support for Supernovas, Dressrosa and Donquixote Pirates. If those decks are what you play or collect, the regular OP-10 box is the direct route to the set.

How does shipping and payment work for OP-10 from Tokyo?

OP-10 ships from Tokyo by FedEx, with two service levels you pick at checkout. Shipping cost is calculated automatically from your delivery address, and there is no minimum order amount or quantity.

Per the shipping policy, those transit times are estimates only, and they do not include handling time, weekends, Japanese national holidays or customs processing. Most orders are processed and shipped within 5 business days after PayPal or Wise payment has cleared, and that window is also an estimate. FedEx cannot deliver to P.O. Boxes, so give a physical address.

After handoff to FedEx, timing is controlled by the carrier and destination-country authorities, and customs inspections or import procedures may delay delivery. The policy says such transit delays are outside the shop’s control.

The payment methods page states that all payments are made in Japanese yen. Any difference between the amount charged and the amount on your statement comes from exchange rates and fees charged by your card issuer, bank or PayPal, and is outside the shop’s control. For Wise orders, the payment deadline depends on whether you upload a screenshot of the transfer, so read that section before you choose.

What should I check before buying OP-10 for its rare slots?

Check three things: which edition you are buying, which rarity labels the source uses, and whether you want a random box or a specific card.

1. Edition. This guide covers the Japanese edition released November 30, 2024. The English-site page lists a Treasure Rare and a March 21, 2025 date, so do not mix the two lists.
2. Labels. The English rarity table uses Secret Rare and Special Card. The Japanese announcement uses Super Parallel for Trafalgar Law. Match each source’s own terms rather than translating between them.
3. Randomness. A sealed booster box is random. The product page states that individual card pulls are not guaranteed.

Cards from OP-10 are tournament legal from the pre-release date in your region, according to the official English page, so the set is playable as well as collectible.
