OP-12 Legacy of the Master Guide: Box, Cards, Rarities

OP-12 (OP12) is the 12th ONE PIECE CARD GAME booster pack, named Legacy of the Master in English. This guide covers the Japanese edition: the 24-pack booster box (update: currently sold out — restock requests via Quick Order), the rarity breakdown, featured cards by number, retail prices and how shipping from Tokyo works.

What are the key facts about OP-12?

OP-12 is the set code of BOOSTER PACK -LEGACY OF THE MASTER-, the 12th ONE PIECE CARD GAME booster. The table gives the names, dates and contents, with a source for each row.

Everything here comes from the official ONE PIECE CARD GAME sites, Bandai’s catalog and our own product and policy pages. Where those sources differ, the article shows both figures side by side.

When was OP-12 released in Japan and overseas?

OP-12 was released on May 31, 2025 in Japan and on the Asia English site, and on August 22, 2025 for the English edition. Three official sources describe these two release windows.

The Japanese edition is the one we ship from Tokyo. Our own booster box page gives May 24, 2025 as the Japanese release date, a week earlier than Bandai’s catalog; use Bandai’s May 31, 2025 as the reference for the set.

The English page shows a “legal date” of August 29, 2025, one week after the release date. It also states that cards in the product are tournament legal from the pre-release date in your region. If you play in an English-language region, the official English page is the place to check the schedule that applies to you.

All of these dates are in the past as of November 11, 2026, so OP-12 is a released set and nothing in this guide is a pre-order.

What is OP-12 Legacy of the Master about?

OP-12 Legacy of the Master is a booster pack built around mentor and student pairs from the One Piece story. Bandai’s catalog says the pack expresses, in cards, the stories between characters who had drama in the original work, and it names Zoro and Mihawk, and Sanji and Zeff, as examples.

The Japanese title (師弟の絆) is rendered in English as Legacy of the Master, and our booster box listing describes the set as honoring the legendary masters and mentors of the One Piece world, those who shaped the next generation of pirates and warriors.

The featured-card heading on the official English page names “Dark King” Rayleigh. Silvers Rayleigh is the Leader card OP12-001, and the official card list shows Zeff as the Uncommon OP12-072. Zoro, Sanji and Mihawk appear as OP12-020 Roronoa Zoro (Leader), OP12-041 Sanji (Leader) and OP12-030 Dracule Mihawk (Super Rare).

Bandai lists the product as a card item for ages 9 and up, sold in toy sections of stores. It notes that photos may differ slightly and that information is subject to change.

What is inside OP-12, and how many card types are there?

The official English page lists 128+1 card types in OP-12, while the Asia English page lists 127+1. Each pack has 6 cards, and the English rarity breakdown adds up to 128 cards plus one DON!! card.

Sources: official English page and Asia English page.

The two pages give different totals, so use the card list when you need an exact card number.

Both pages carry the same cautions. Because of the nature of the product, multiples of one card may appear, and it may be difficult to assemble a full set. The illustrations may differ somewhat from the final product, and product details may differ from the actual product. The Asia page also mentions a questionnaire that unlocks a downloadable play sheet.

The official OP-12 card list on the Asia English site shows 154 results. That is a larger number than the card-type count, so the card list is the reference for exact card numbers. For a full explanation of the rarities, read our OP-12 rarities explained guide.

Which cards are featured in OP-12?

The table lists cards that the official card list shows by name and number.

Sources: the official OP-12 card list, plus searches for Luffy, Pudding, Reiju and Shirahoshi.

This is a selection, not the full 154-result list. The six Leaders in the table match the six Leader Cards in the rarity breakdown. The official card list also shows Rare event cards such as OP12-039 “Luffy Is the Man Who Will Become the King of Pirates!!!” and OP12-079 “Luffy Is the Man Who Will Be King of the Pirates!!!”, plus OP12-037 “Demon Aura Nine Sword Style Asura Blades Drawn Dead Man’s Game” and the Rare OP12-006 Shakuyaku.

Our product page names Silvers Rayleigh, Gol D. Roger, Red-Haired Shanks and Zeff as key cards and mentions alternate-art chase cards. The official card list pages used here confirm Silvers Rayleigh (OP12-001) and Zeff (OP12-072) by number. The official English page lists these featured card numbers: OP12-001, 015, 018, 020, 030, 041, 056, 072, 094 and 100.

How do I read OP-12 card numbers and rarity codes?

An OP-12 card number starts with OP12 followed by a three-digit number, and the rarity is shown as a short code. The official card list uses the codes L, UC, C, R, SR and SEC.

Use the number, not the character name, when you look for a card. The same character can appear more than once in the set: Luffy has the Super Rare character OP12-015 and two Rare event cards, OP12-039 and OP12-079, whose titles differ by only a few words. Reading the number avoids mixing them up.

The rarity breakdown on the booster page also lists Special Cards, Treasure Rare, 3rd Anniversary Special Cards and a DON!! card. For how those groups differ, see our OP-12 rarities guide.

If you want to search the English card list by name, the official site supports a free-word search within the set, as in the Luffy, Pudding, Reiju and Shirahoshi searches linked above. Those searches return the card number, rarity and card type, which is everything you need to compare a listing against the official entry.

What is inside a Japanese OP-12 booster box?

A Japanese OP-12 booster box holds 24 booster packs of 6 cards each, which makes 144 cards per box. This comes from our OP-12 Legacy of the Master Japanese One Piece Booster Box (update: currently sold out — restock requests via Quick Order) page, and it is a Japanese Original Edition product.

The box is sold brand new and sealed. It is a randomized product: cards are packed at the factory, and which cards you get cannot be known in advance. Multiples of one card can appear, as the official pages warn, so a single box is not a route to a complete set.

Our listing is in stock at the time of writing. The same page says the box ships directly from our warehouse in Tokyo via FedEx with tracking and insurance; the shipping terms are in the buying section below.

What is the damaged-box version?

The damaged-box listing is the same OP-12 booster box sold at a discount because of cosmetic damage to the outer box, such as dents or scratches. The page states that the cards inside are unaffected. The OP-12 Damaged Box listing is also in stock at the time of writing.

Read the terms before you choose it. The photos are samples, and the first image shows the regular product so you can identify the set. The item you receive may differ from the sample photos, the type and extent of damage vary, and the item is sold as-is. The page says that we do not respond to inquiries about this item and that returns and refunds are not accepted.

The page explains the origin: our Tokyo warehouse takes in large volumes of Japanese trading cards every day, and boxes that cannot be sold as mint condition are separated during inspection and stored, then offered at a lower price than regular products.

How much does OP-12 cost at retail?

The official MSRP of OP-12 is USD $4.99 per pack in the English edition and 220 yen including tax per pack in Japan. Those are the suggested retail prices from the official English page and Bandai’s catalog.

These are per-pack prices from the official pages. The last column is simple multiplication by the 24 packs in a box. Our current box prices are shown on the booster box page (update: currently sold out — restock requests via Quick Order), which is the source for what a box costs in our shop. We do not forecast how OP-12 prices will move.

What is the difference between the Japanese and English editions of OP-12?

The Japanese edition released on May 31, 2025 and the English edition on August 22, 2025, and the two official pages count the cards slightly differently. The Japanese edition is the one in our listings.

• Release date: May 31, 2025 for Japan and the Asia English site, August 22, 2025 for the English edition.
• Card count: 127+1 on the Asia page versus 128+1 on the English page.
• Price: 220 yen (tax included) per pack in Japan versus MSRP USD $4.99 for the English edition.
• Language: Our listing is labeled Japanese Original Edition.

If you play officially in an English-language region, check which edition and date your local tournament rules apply to. The English page says cards in the product are tournament legal from the pre-release date in your region. For collecting, the Japanese edition is a clear choice if you want the original Japanese product.

How do I buy OP-12 from Tokyo and what are the shipping terms?

You can order the Japanese OP-12 booster box from our shop and we ship it from Tokyo via FedEx. Standard shipping is FedEx International Connect Plus with tracking, and expedited shipping is FedEx International Priority with tracking, per our shipping policy.

Both transit times are estimates only. Shipping cost is calculated at checkout from your delivery address. There is no minimum order amount or quantity, so you can order a single box.

Processing time is separate from transit time. The policy says most orders are processed and shipped within 5 business days after PayPal or Wise payment has cleared, and describes that window as an estimate. Business days exclude weekends and Japanese national holidays. If dispatch is delayed, we contact you by email with a revised estimate.

Once an order is with FedEx, delivery timing is controlled by the carrier and destination-country authorities. Customs inspections, import procedures, peak season congestion and weather can delay delivery. FedEx cannot deliver to P.O. Boxes, so enter a physical address at checkout.

Which payment methods can I use?

Our payment methods page lists Wise bank transfer, PayPal, credit and debit cards through PayPal (Visa, Mastercard, American Express and JCB, as offered by PayPal for your country and card) and PayPal Pay Later where PayPal makes it available. All payments are made in Japanese yen.

Wise bank transfer carries no payment processing fee. PayPal and card payments carry the 5% payment processing fee described on that page. Exchange-rate and conversion differences on your statement are decided by your payment provider.

How should I choose between the box, the damaged box and the card list?

Buy the regular sealed box if you want the full 24-pack product, choose the damaged box if you accept the as-is terms and plan to open the packs, and use the official card list if you only need to identify one card.

If you want a box to keep sealed, the regular box is the one to pick, because the damaged box has dented or scuffed outer packaging by definition. If the outer condition does not matter to you, the damaged box is built for that buyer.

A sealed box is randomized, so no listing can name the cards inside. The official pages note that multiples can appear and that a full set is hard to assemble from packs alone, so treat a box as an opening experience first.

Stock changes often for sealed Japanese trading card products, as our shipping policy states. The product pages show the current state.
