All Union Arena Sets: Complete EN Release Schedule (2026)

All Union Arena sets follow a distinctive release pattern, and it is not the one most TCG players expect.

Union Arena's release strategy differs from most card games. Rather than one core game with expansions, Bandai releases IP-specific boosters where each set focuses entirely on a single anime franchise. The English line launched in late 2024 and has since released sets at a near-monthly pace across a rotating cast of IPs.

TL;DR: All Union Arena sets are single-IP boosters. The English line began in September 2024 with Bleach: Thousand-Year Blood War and Hunter x Hunter, with Jujutsu Kaisen following in November; the line has released 29 sets since, 10 in 2026 alone, at a near-monthly cadence. EN sets use the UExxBT code format (Japanese sets use UAxxBT, e.g. InuYasha is UA50BT). Solo Leveling was the first English-first release (March 2026); InuYasha released August 14, 2026, with Re:ZERO and Attack on Titan Vol. 2 next on September 18. Always confirm exact codes on the official products page.

All Union Arena sets: quick answer

There is no short "8 sets" answer: Union Arena EN already spans 29 booster-type sets, each tied to a different anime IP, released roughly monthly since the September 2024 launch. Sets use the UExxBT code format in English. To track them you follow the IP + release-date timeline, not a tidy set-number sequence, and you confirm exact codes on the official products page because EN and JP numbering differ.

Union Arena EN Sets by Release (2024-2025)

English boosters are numbered UE01BT onward, but not strictly by shelf date: Vol. 2 sets use a separate UEX0xBT code and interleave with the main numbering. The 2024-2025 run, verified against the official EN products page:

That is nineteen booster-type releases in the first ~15 months (14 main-numbered sets plus 5 Vol. 2 sets), a far faster cadence than most TCGs. Confirm exact card counts and codes per set on the official products page.

Union Arena EN Sets (2026)

2026 has kept the near-monthly pace, and includes the line's first English-first release:

• Sword Art Online Vol. 2 (UEX06BT) , January 30, 2026
• Evangelion (UE15BT) , January 30, 2026
• Kagurabachi (UE16BT) , February 27, 2026 (Red Kagurabachi is the current #1 EN meta deck)

• InuYasha (UE23BT) , August 14, 2026, released (cards use the UA50BT code in the JP database)

That is ten 2026 releases so far. The confirmed schedule already runs past InuYasha into 2027; see the next section.

Union Arena EN spans 29 single-IP sets since the September 2024 launch, released at a near-monthly pace across a rotating cast of anime franchises.

How the IP Sets Work

Because each set is one IP, "learning Union Arena" means picking an IP and learning its set. A few of the most-played EN IPs:

• Jujutsu Kaisen , the launch IP; control-leaning with disruptive effects. Our Union Arena JJK guide covers the Domain Expansion mechanic and top decklists.
• Bleach , a transformation game plan built around Ichigo's Hollow form.
• Solo Leveling , an aggressive, consistent archetype and a popular entry point. The Union Arena Solo Leveling guide has the full competitive breakdown.
• Hunter x Hunter, Demon Slayer, Code Geass , each with multiple volumes and deep card pools.

Every set shares the same core rules (AP, energy line, front line, Life, Impact, triggers); only the IP-specific cards and themes change. So skills transfer fully between sets even though decks are single-IP.

Upcoming Union Arena EN Sets

InuYasha (UE23BT) released August 14, 2026 and is the most recent EN set as of this update. See our Union Arena InuYasha English release guide for set details and release-window logistics on that launch. Bandai has already published a confirmed schedule running well past it:

• Re:ZERO -Starting Life in Another World- and Attack on Titan Vol. 2 , September 18, 2026
• Goddess of Victory: NIKKE Precious Booster Pack , October 23, 2026
• Bleach: Thousand-Year Blood War Advanced Deck , November 6, 2026
• Bleach: Thousand-Year Blood War Vol. 3 , November 13, 2026
• My Hero Academia Special Booster Pack , December 11, 2026
• Gurren Lagann , January 22, 2027
• Umamusume: Pretty Derby (Starter Deck February 5, Booster Pack February 12, 2027)
• D.Gray-man , March 19, 2027

Bandai typically confirms new EN dates a few months ahead; watch the official Union Arena EN channels for anything past March 2027.

Dragon Ball in English is primarily the separate Fusion World game, not Union Arena; there is no confirmed Dragon Ball EN Union Arena set as of August 2026.

Always verify against the official products page before buying, since the lineup changes monthly.

Which Set Should You Buy?

• Beginners: Solo Leveling is the most beginner-friendly entry; InuYasha (released August 14) is another solid starting point.
• Competitive: Jujutsu Kaisen and Solo Leveling are consistently strong; check current event results before committing.
• Collectors: pick the IP you love, that is the whole appeal of the multi-IP model, or target InuYasha at launch.

Frequently Asked Questions

Does Union Arena have a world championship? Yes. Bandai runs official Union Arena events with regional qualifiers. Check the official site for the current schedule.

Can I buy English Union Arena cards at Japanese game stores? EN cards are region-specific and typically not stocked at JP retailers (which carry the UAxxBT JP versions). Import stores carry both globally.

Are Japanese Union Arena cards playable in EN tournaments? Generally no. Official EN tournaments require EN card versions. Some local events allow both; confirm with your organizer.

How big is the Union Arena player base compared to One Piece TCG? Smaller than One Piece TCG but growing; the multi-IP approach gives it wide casual reach across many fandoms.

Why do EN and JP set numbers differ? The English line launched later and renumbered under the UExxBT codes, so a set's EN number does not match its original JP UAxxBT number. Always match by IP and date, then confirm the code officially.
