What “4th Anniversary” Means for OP-17 and OP-18
The official product page for OP-17 marked the milestone directly: “ワンピカードはついに4周年を迎える！” — roughly, “the One Piece Card Game is finally reaching its 4th anniversary.” OP-17 The World’s Strongest Warriors carried that wording as the first 4th-anniversary booster, releasing on August 22, 2026.
OP-18 神の支配 was announced at ONE PIECE DAY’26 as the second 4th-anniversary booster. Card reveals for OP-18 are being posted on the official ONE PIECE CARD GAME X account under the heading “OP-18カード紹介,” including a character card, 海ネコ (Sea Cat), posted on September 22, 2026.
Between the two anniversary boosters sits a separate Japanese release, EB-05. Bandai’s official Japanese product page for エクストラブースター ONE PIECE Heroines Edition vol.2【EB-05】 prints the release date as Saturday, October 31, 2026, at ¥240 per pack (tax included) and 6 cards per pack, as of October 6, 2026. The official English site lists EXTRA BOOSTER -ONE PIECE HEROINES EDITION vol.2- [EB-05] with a release date of October 30, 2026 at USD $4.99 per pack and 75+2 types in total, as of October 6, 2026; the English page does not print cards per pack or per-rarity counts. The official page describes it as the second Extra Booster built around the series’ heroines, and the official release-event page schedules shop events from October 31 to November 15, 2026. We list no EB-05 product; our EB-05 card list covers its reported Leaders and Heroines SP cards, our EB-05 parallel and super parallel list covers the parallel versions, and the EB-05 or OP-18 comparison covers the two Japanese boxes.
