OP-12 Rarities Explained: Secret Rare, Super Rare and Special Cards

OP-12 (OP12) Legacy of the Master has six main rarity tiers in its Japanese edition: Leader, Common, Uncommon, Rare, Super Rare and Secret Rare. The Secret Rare tier is the smallest numbered tier, with just two cards. Special Cards sit outside those tiers and carry their own counts. This guide explains what each tier means and how to read the codes.

Key facts: what is OP-12 and what is in it?

OP-12 is BOOSTER PACK -Legacy of the Master- [OP-12], the twelfth ONE PIECE CARD GAME booster set, released in Japan on May 31, 2025. The table fixes the names and numbers used in the rest of this guide.

One date note: our product page prints May 24, 2025 as the Japanese release date, while the official page and the Bandai catalog both say May 31, 2025. This guide uses the official date.

What do the OP-12 rarity tiers mean?

The official card list uses the codes L, C, UC, R, SR and SEC, and each code is a separate tier with its own card count. Leader (L) is a group of its own, and the other five run from Common (C) at the base to Secret Rare (SEC) at the top.

Source: the official OP-12 page. The lines add up to 127, which matches the “127+1” card types the page states for one pack.

The count in each tier is a count of different designs, not a statement about how often a card appears in a pack. The official page gives no pull-rate figures, and this guide does not either. The page does say: “Due to the nature of the product, multiples of one card may appear, or it may be difficult to assemble a full set.” Keep that line in mind when you decide how many packs to open.

Reading the table from the top, the Secret Rare tier has 2 designs, the Super Rare tier has 10, and the Rare tier has 26. A collector who wants a specific design in a small tier is choosing among very few cards, and a collector who wants a complete playset of Commons is choosing among 45. That difference in the size of the pool is the practical meaning of the tiers in this set.

Which two cards are the OP-12 Secret Rares?

The two OP12 Secret Rare cards are OP12-118 Jewelry Bonney and OP12-119 Bartholomew Kuma. The official OP-12 page lists “Secret Rare x 2”, and the official card list names the two cards.

If a listing claims a third OP-12 Secret Rare, check the card number against this table and the official card list. The English official page also gives a count of two Secret Rares. It shows a separate Treasure Rare line, covered below, which is not part of the SEC tier.

The official sources print only the number, name and rarity for these two cards, so this guide does not describe their effects or artwork. What you can rely on is identification: a card reading OP12-118 is Jewelry Bonney, and a card reading OP12-119 is Bartholomew Kuma. Check the printed number rather than relying on a photo, because OP-12 also includes parallel and Special printings of other characters.

How is a Super Rare different from a Secret Rare in OP-12?

A Super Rare is the tier directly below Secret Rare, and OP-12 has ten of them against two Secret Rares. Many headline characters sit in the SR tier, not in SEC, so a popular name does not mean a Secret Rare.

Source: the official OP-12 card list. The count of ten matches “Super Rare x 10” on the product page.

Luffy, Law, Robin, Mihawk, Garp and Dragon are all SR. A collector who wants a Luffy from OP-12 is looking at OP12-015, a Super Rare, and not a Secret Rare. Four of these numbers, OP12-015, OP12-030, OP12-056 and OP12-094, also appear among the ten card numbers the official page shows in its highlight strip (001, 015, 018, 020, 030, 041, 056, 072, 094, 100). That strip gives numbers without names in its text, so the card list is the source for who each number is.

For how collectors rank these cards against the rest of the set, see our OP-12 chase cards guide. This article covers what the tiers are, not what a card is worth.

Where do the six OP-12 Leaders fit in the rarity system?

Leaders are their own group with the code L, and OP-12 has six of them. They are not a step on the Common-to-Secret ladder, and they are not Secret Rares.

The official page highlights “The ‘Dark King’ Rayleigh joins the battle!” and “The new ‘Twin Wings’ leader cards are here!”, and Rayleigh is the OP12-001 Leader. Bandai’s catalog text for the Japanese pack points to pairings such as Zoro and Mihawk, and Sanji and Zeff. In the card list those pairings show up as the Zoro Leader, the Mihawk Super Rare and the Zeff Uncommon, and as the Sanji Leader.

What are Special Cards, Treasure Rare and the DON!! Card in OP-12?

Special Cards are a separate group from the numbered tiers: the Japanese-region page counts six Special Cards and two Special 3rd Anniversary Cards, and the English page adds one Treasure Rare and one DON!! Card. The official text gives these as counts, not as named lists.

• The Japanese-region page lists “Special Cards x6” and “Special 3rd Anniversary Cards x2” (source).
• The English page lists “Special Card 6”, “3rd Anniversary Special Card 2”, “Treasure Rare 1” and “DON!! Card 1” (source).

Our guide to the OP-12 parallel and SP cards goes through the alternate-art side in more detail, so this guide stops at the counts.

Why can a card numbered OP06 belong to the OP-12 set?

Because a Special (SP) card can carry the number of its original set while being listed under OP-12. The official English card list shows Tashigi OP06-050 as an SP CARD (Character, Cost 1, Power 2000, Counter 1000) listed under LEGACY OF THE MASTER [OP-12] (source).

The same search shows the set’s regular Tashigi, OP12-031, as a Rare (Character, Cost 5, Power 7000). Two cards of one character, two different numbers, two different rarity labels, and both are tied to OP-12 in the list. The lesson for anyone searching: do not filter on the “OP12-” prefix alone, and do not assume that every OP-12 Tashigi is the Rare.

Which Rares and Uncommons does the official card list show?

The card list names four Rares and two Uncommons as examples, which show how the lower tiers are numbered. They are not the full tiers, which hold 26 and 30 cards.

Source: official card list. Our product page names Silvers Rayleigh, Gol D. Roger, Red-Haired Shanks and Zeff as key cards of the set, along with alt-art chase cards. Rayleigh is the OP12-001 Leader and Zeff is the OP12-072 Uncommon. The sources used here give no card numbers for Gol D. Roger or Red-Haired Shanks.

The point for a rarity guide: a tier tells you how a card is printed, not how important the character is. Edward.Newgate is an Uncommon at OP12-002, and Zeff, a key card on our product page, is also an Uncommon. For the full numbered list across every rarity, use our OP-12 card list.

How do the Japanese and English OP-12 rarity counts compare?

They match for Leader, Common, Uncommon, Rare, Super Rare, Secret Rare, Special Card and 3rd Anniversary Special Card, and differ only in the extra lines the English page adds.

Sources: Japanese-region page and English page. The English lines other than the DON!! Card add up to 128, which matches “128+1”.

The dates and prices also differ. The English set is listed with a release of August 22, 2025 and a legal date of August 29, 2025, against May 31, 2025 for the Japanese set. The English page states a pack MSRP of USD $4.99, while the Japanese pack is 220 yen including tax. The English page also says cards are tournament legal from the pre-release date in your region. Our box is the Japanese edition. For a side-by-side of the two box types, read our OP-12 booster box guide on Japanese vs English.

How should you read a rarity code in a listing?

Read the code and the card number together: the code names the tier and the number names the card. In the official card list the SEC code appears on OP12-118 and OP12-119, the SR code on the ten cards in the table above, and the L code on the six Leaders.

• Check the number first. A number such as OP12-015 is a Super Rare Luffy; OP12-119 is the Secret Rare Kuma.
• Check the prefix rule. An SP card may carry another set’s prefix, as the Tashigi OP06-050 example shows.
• Compare against the official list. The official page counts two Secret Rares, so check any other Secret Rare claim against the official card list.
• Do not treat the tier as a value statement. The official page gives no pull rates and no prices for single cards, and neither does this guide.

These checks are cheap and take a minute. They matter most for the Special group, where a card’s number alone does not tell you which set page it sits under.

What does a Japanese OP-12 booster box give you?

Our Japanese OP-12 booster box holds 24 packs of 6 cards, or 144 cards, and the contents are random. The OP-12 Legacy of the Master Japanese booster box (update: currently sold out — restock requests via Quick Order) is listed as brand new and sealed.

The page states that this is a sealed, randomized product: cards are packed at the factory and a specific Secret Rare or Special Card cannot be promised. If you need one named card, a single is the direct route; if you want to open packs, the box is the product.

There is also a discounted OP-12 Damaged Box (update: currently sold out — restock requests via Quick Order) listing. It is discounted because of cosmetic damage to the outer box, such as dents or scratches, and the cards inside are described as unaffected. The photos are samples, the item is sold as-is, and returns and refunds are not accepted. If packaging condition matters to you, take the regular box.

For a full buying walkthrough, see the OP-12 booster box buying guide.

How does ordering OP-12 from Tokyo work?

You pay in Japanese yen by Wise, PayPal or card through PayPal, and the box ships from Tokyo by FedEx. The details come from our shipping policy and payment methods page.

After dispatch, delivery timing is controlled by FedEx and the destination country’s authorities. The policy lists customs inspections and import procedures among the causes of delay and says such transit delays do not by themselves create a right to cancel or refund after dispatch.

For Wise, the deadline depends on whether you upload a transfer screenshot at checkout. Without a screenshot the order is cancelled automatically if payment has not arrived within 12 hours; with a screenshot you have 5 days to upload it. The payment reference, in the form SST-{order number}, must be entered exactly as issued.
