OP-18 — titled BOOSTER PACK –THE DOMINANCE OF GOD– [OP-18] in English and ブースターパック「神の支配」 in Japanese — is the next mainline One Piece Card Game booster after OP-17, and it was revealed at ONE PIECE DAY ’26 through Bandai’s official Japanese and English X accounts.
As of September 15, 2026, Bandai’s official product pages for OP-18 are not yet live, so there is no confirmed release date, no official card list, and no officially hosted card images to show. What exists is a set of early reveals passed along by secondary hobby outlets who covered the ONE PIECE DAY ’26 stream, plus one detail attributed to Bandai’s own English account (seen only through a search-engine snippet of the post): OP-18 is reported to follow OP-17’s global simultaneous release format. This guide lays out exactly what is confirmed, what is reported-but-unverified, and how OP-18 lines up against OP-17’s release cadence.
- OP-18 “The Dominance of God” was announced at ONE PIECE DAY ’26; Bandai’s official product pages are not live as of September 15, 2026, so the exact JP release date is unconfirmed — secondary sources conflict between November 21, 22 and 28, 2026.
- Bandai’s official English X account is quoted as saying OP-18 will use the same global simultaneous JP/EN release format that OP-17 debuted in August 2026 (the post itself could only be seen through a search snippet).
- Reported (not yet official) pack structure: ¥240 per pack, 6 cards per pack, 24 packs per box.
- Early reveals attributed to secondary outlets include a first Franky Leader card and a new “God’s Knights Super Parallel” rarity tier, plus guest-artist parallels credited to Yoshitaka Amano.
- Our OP-16 booster box (update: currently sold out — restock requests via Quick Order) is the latest One Piece booster currently listed from Tokyo; OP-17 sourcing requests go through Quick Order.
Facts checked September 15, 2026. Bandai’s official OP-18 product pages were not yet live on this date; every number below that is not confirmed on an official page is marked as reported by secondary sources.
What Is OP-18 “The Dominance of God”?
OP-18 is the next numbered mainline booster in the One Piece Card Game, following OP-17 “The World’s Strongest Warriors” which released in Japan on August 22, 2026. Bandai’s official Japanese account (@ONEPIECE_tcg) and English account (@ONEPIECE_tcg_EN) revealed the set during ONE PIECE DAY ’26, with the English account quoted as posting the English title BOOSTER PACK –THE DOMINANCE OF GOD– [OP-18].
Set code is OP-18. Secondary coverage of the reveal stream reports two themes for the set: a “God’s Knights” (神の騎士団) faction, and an original arc built around Water Seven, with some outlets also noting possible overlap with Elbaf and World Government material carried over from OP-17 — none of these connections are confirmed and should be treated as speculative until the official card list is published. Japanese hobby site Torecamap frames OP-18 as continuing the commemorative run Bandai started with OP-17 for the card game’s 4th anniversary.
Two Leader cards have been described by outlets covering the reveal: a first Leader card for Franky (Green/Purple), and a second Leader in Purple/Black tied to a character whose name is rendered inconsistently across sources — we are not printing that name as confirmed until Bandai’s own page is live.
JP and EN Release Timing
Bandai’s official English account is quoted as saying that OP-18 will use the same global simultaneous release format that OP-17 introduced, meaning the Japanese and English versions are planned to reach retail on the same day.
The exact Japanese release date is not yet confirmed. Bandai’s official OP-18 product pages return no live content as of September 15, 2026, and secondary outlets do not agree with each other — reported dates include November 21, November 22 and November 28, 2026. Until the official page is published, the honest answer is “November 2026, exact date not yet announced.”
The expected product-page path for OP-18 is asia-en.onepiece-cardgame.com/products/op18.html. As of September 15, 2026 that URL was still inactive for OP-18.
Box and Pack Structure
Secondary sources covering the ONE PIECE DAY ’26 reveal report the following pack structure for OP-18. OP-17’s official product page states 6 cards per pack; the figures below for OP-18 are reported, not yet confirmed on an official page:
| Detail | Reported figure | Status |
|---|---|---|
| Price per pack (JP, tax incl.) | ¥240 | Reported by secondary outlets, not yet on an official page |
| Cards per pack | 6 | Reported |
| Packs per box | 24 | Reported |
| Box MSRP (JP) | ¥5,760–¥5,780 | Sources disagree by ¥20; unverified |
| Total card count / rarity split | Not confirmed | A circulating figure matches OP-17’s structure exactly, which may mean it is a template guess rather than OP-18-specific data |
One reported first for the set: a new rarity tier called “God’s Knights Super Parallel” (神の騎士団スーパーパラレル), alongside guest-artist parallel cards credited to Yoshitaka Amano — the character designer known for the Final Fantasy series — reportedly applied to at least two cards. Both details come from secondary coverage of the reveal stream, not an official card list.
Cards Revealed So Far
No officially hosted OP-18 card images exist yet — the standard Bandai image URL pattern returns no result for every OP-18 number checked as of September 15, 2026. The cards below are early reveals reported around ONE PIECE DAY ’26 by outlets that covered the stream. Card numbers, rarities and even character names vary between sources, so treat this table as a starting point, not a confirmed card list.
| Card # (as reported) | Character | Rarity (as reported) | Consistency across sources |
|---|---|---|---|
| OP18-021 | Franky | Leader — first Franky Leader card | Consistent |
| OP18-031 | Nico Robin | Super Rare / “Super Parallel” (label varies) | Card # and name consistent; rarity label varies |
| OP18-060 | Second Leader (name unverified) | Leader | Slot repeated across two sources; name unreliable |
| OP18-065 | Same character as OP18-060, alt art | “God’s Knights Super Parallel” | Unverified name |
| OP18-078 | Mini Merry-Go | Uncommon | Card # consistent; colour conflicts between sources |
| OP18-119 | Shamrock Saint | Secret Rare + Amano-artist parallel | Consistent |
One outlet also lists an Amano-style parallel of Loki, but mislabels its card number as belonging to OP-17 rather than OP-18 — most likely a reprint or parallel treatment of the existing OP-17 Loki card appearing again inside OP-18’s guest-artist subset, rather than a genuinely new card number. We are flagging it rather than resolving it, since neither an official card list nor a clean secondary source settles the question yet.
How OP-18 Compares With OP-17’s Cadence
OP-17 “The World’s Strongest Warriors” released in Japan on August 22, 2026, with the English version following on August 28, 2026 — the format Bandai then formally adopted as its Global Simultaneous Release model. If OP-18’s reported November 2026 window holds, the gap between OP-17 and OP-18 works out to roughly three months, which is consistent with Bandai’s booster cadence through 2026.
OP-18 is reported as a same-day JP/EN release, continuing the Global Simultaneous Release format that OP-17 introduced; that report is attributed to Bandai’s English account via a search snippet and is not yet on an official product page.
