OP-18 Release Date
Bandai's official Japanese product page confirms the Japanese release of OP-18 for Saturday, November 21, 2026. Bandai's official English site lists OP-18 for November 20, 2026, and Bandai's official Asia site lists it for November 21, 2026. Cards become tournament-legal 7 days after release in each region.
Theme: Water Seven and the Holy Knights of God
OP-18 pairs two very different sides of the One Piece world. Water Seven is the shipbuilding city where the Straw Hats' story takes one of its most dramatic turns. The Holy Knights of God are the elite knights of the Celestial Dragons, the World Government's most powerful force. Bandai built the set around the idea of the World Government's greatest power, so expect the Holy Knights to be at the centre of OP-18.
New in OP-18: Saint Gunko and Saint Shamrock
Bandai confirms that Saint Gunko and Saint Shamrock make their ONE PIECE CARD GAME debut in OP-18. Both are members of the Holy Knights of God, and their first-ever cards are likely to draw strong interest from players and collectors.
OP-18 Card List: Revealed Cards (Preview)
OP-18 contains 127 + 1 card types. Preview: the cards below come from pre-release reveals and Japanese card-list reports. Bandai has not yet published the official OP-18 card list, so card numbers, names and colors may change. Numbers marked "unconfirmed" have conflicting reports.
OP-18 Leaders (reported)
- OP18-001 Karoo (Red/Blue)
- OP18-021 Franky (Green/Purple), with a parallel version
- OP18-022 Monkey.D.Luffy (Green)
- OP18-041 Miss All Sunday (Blue)
- Saint Gunko (Purple/Black), with a parallel version, card number unconfirmed
- Spandam (Black/Yellow), card number unconfirmed
OP-18 Secret Rare (reported)
- OP18-119 Saint Shamrock (Black), reported with two parallel versions
As the Holy Knight making his card game debut, Saint Shamrock's Secret Rare and its parallels are the headline chase cards revealed so far.
OP-18 Super Rares (reported)
- OP18-011 Nefeltari Vivi
- OP18-031 Nico Robin (with a Super Parallel)
- OP18-034 Franky
- OP18-046 Mr.0 & Miss All Sunday
- OP18-048 Mr.1 & Miss Doublefinger
- OP18-061 Iceburg
- Saint Gunko (with a Super Parallel), card number unconfirmed
- OP18-084 Saint Gunko
- OP18-100 Kalifa
- OP18-113 Rob Lucci
Water Seven favourites like Franky, Iceburg, Kalifa and Rob Lucci sit alongside Alabasta's Baroque Works pairs (Mr.0 & Miss All Sunday, Mr.1 & Miss Doublefinger), so OP-18 covers more than one arc. Bandai has not published the rarity breakdown, SP cards or Manga Rares yet. We'll add them once they are officially revealed.
As with every booster set, Bandai notes that multiple copies of the same card can appear, so completing a full set can be difficult.
OP-18 Release Event: 4th Anniversary
Bandai is celebrating OP-18 and the game's 4th anniversary with official store events from November 20 to December 17, 2026 (English events). Participating stores choose Constructed, Sealed or Standard Regulation formats. Official event items include:

Japanese vs. English OP-18
OP-18 releases in English on November 20, 2026 and in Japanese on November 21, 2026. Many collectors prefer Japanese booster boxes for their print quality and card stock, and Japanese copies of popular cards, especially parallels, SP cards and alternate-art Leaders, are often in high demand. Japanese cards are tournament-legal in Japanese-language events, so check your local organizer's rules if you plan to play.
