One Piece OP-15: Adventure on Kami's Island

OP-15 is the One Piece booster Adventure on Kami’s Island, built around the Skypiea arc. In English it is sold as OP15-EB04, the 15th booster pack set. It was released on April 3, 2026, after the Japanese OP-15 on February 28. The two are not the same size: Japan’s set has 125 card types plus a DON!! card, and the English set 159 plus one. The English set holds every OP15 entry from the Japanese set and adds 30 card numbers from EB04, three more Special cards and a Treasure Rare.

When did OP-15 come out, and what does it cost?

The Japanese pack holds 6 cards.

For the pack size, check the wrapper or see our guide to One Piece booster box contents. Our One Piece set release dates guide sets OP-15 in the full run of boosters.

Why does the English set have more cards than Japan’s?

Because it adds cards numbered EB04.

• The OP15 half matches. All 146 OP15-numbered entries in the English set are in the Japanese set too, with the same rarity on each.
• It adds 41 EB04 entries. They cover 30 card numbers: EB04-001 to EB04-010 and EB04-042 to EB04-061. The other 31 numbers, EB04-011 to EB04-041, are in the English set OP14-EB04, released January 16, 2026.
• Together they cover Japan’s EB04 cards. The two English sets hold all 81 EB04-numbered entries of Japan’s EB-04 set, with none in both.

Our guide to One Piece extra boosters covers Japan’s EB-04 and the other EB sets.

The split follows color. The EB04 cards in OP15-EB04 are red, black and yellow, with a Red/Yellow Jewelry Bonney Leader, EB04-001. The ones in OP14-EB04 are green, blue and purple.

How is the OP15 half numbered?

In color blocks. The set’s own cards run from OP15-001 to OP15-119, which is 93 Characters, 19 Events, 1 Stage and 6 Leaders.

Three of the six Leaders are dual-color cards, two at the very front and one opening the green block, and the Black block has no Leader of its own. The last two numbers sit outside the blocks: OP15-118 (Enel, purple) and OP15-119 (Monkey.D.Luffy, yellow) are the set’s own Secret Rares. The card number entry explains how numbers identify a card.

What rarities are in the English set?

The English total checks out: 149 card numbers, plus 9 Special cards and 1 Treasure Rare, make the 159. The EB04 part brings no Uncommons. One card in it is labeled differently across the languages: EB04-053 (Sentomaru) is a Rare on the English list and a Common on Bandai’s Japanese EB-04 list. Our guide to One Piece rarities shows how each rarity is marked.

Which cards are the Special cards and the Treasure Rare?

None of the nine Special cards carries an OP15 number, and they are labeled SP. Sorted by the kind of product the number belongs to:

Japan’s OP-15 list has six of these. The other three, EB04-003, OP11-106 and PRB02-014, are among the six Special cards on Japan’s EB-04 list. The Treasure Rare is a version of OP13-037, Roronoa Zoro, also numbered in another product. If you search the card list for OP15 numbers alone, you will miss all ten.

How many alt-arts does the English set have?

Thirty-seven. Bandai counts types, not alternate art versions. Each one is an extra entry under the same number, and there are 37 such entries, which this guide calls alt-art entries:

Every Leader, Super Rare and Secret Rare has at least one. Two numbers have two: EB04-044 (Koby), a Super Rare, and OP15-118 (Enel), a Secret Rare. Enel is the set’s super alternate art card. Add the 149 standard prints, 37 alt-arts, 9 Special cards and the Treasure Rare, and you reach the list’s 196 entries.

Which characters does the set feature?

The set is built around Monkey.D.Luffy and Enel in the Skypiea arc, with Secret Rares of those two characters, Enel’s super alternate art card and six new Leaders: Krieg, Lucy, Brook, Rebecca, Enel and Monkey.D.Luffy. Japan’s OP-15 card list has the same six Leaders.

How do you check OP-15 card prices?

Rip.fan’s price pages and card price lookup cover English Pokémon cards only, so price an OP-15 card from sold listings:

1. Pin down the version. Search the number on Bandai’s card list, then match the art. OP15-118 brings up three entries, all Secret Rares.
2. Match the language. An English OP15-EB04 pack can hold EB04 cards that a Japanese OP-15 pack does not, and one of them carries a different rarity.
3. Use dated sold prices. Our guides to checking a One Piece card’s value and market, listed and sold prices explain which figure to trust.
4. Check it is genuine. See spotting fake One Piece cards, and buy any booster box as sealed product with the seal intact.

For a newer set mapped the same way, see our OP-17 guide. Our guides to premium boosters and starter decks cover Bandai’s other One Piece products, and the trading card hub collects the rest.
