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

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; 31 booster-type sets had released by September 18, 2026, including 12 in 2026. EN sets use the UExxBT code format, while UEX-prefixed Vol. 2 sets interleave with the main numbering. Solo Leveling was the first English-first release (March 2026); InuYasha released August 14, followed by Re:ZERO and Attack on Titan Vol.2 on September 18. Always confirm exact codes on the official products page.

Updated October 8, 2026: Every date and code re-checked against the official products page and card list. Jujutsu Kaisen is no longer called the launch IP (Bleach and Hunter x Hunter launched first); Re:ZERO list counts and the official top-placing results were refreshed; Mushoku Tensei's UE30BT code was added.

All Union Arena sets: quick answer

There is no short "8 sets" answer: Union Arena EN already spans 31 booster-type sets, each tied to an anime IP, released roughly monthly since the September 2024 launch. The official products page now lists 24 main-numbered boosters and 7 UEX-prefixed Vol. 2 boosters through September 18, 2026. 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 (see the official deck lists for current standings)
• Solo Leveling (UE17BT) , March 20, 2026 (the first English-first Union Arena set)
• Tokyo Ghoul (UE18BT) , April 24, 2026
• Sakamoto Days (UE19BT) , May 29, 2026
• That Time I Got Reincarnated as a Slime (UE20BT) , June 26, 2026
• The 100 Girlfriends Who Really Love You (UE21BT) , July 10, 2026
• Chainsaw Man (UE22BT) , July 31, 2026
• InuYasha (UE23BT) , August 14, 2026, released (cards use the UA50BT code in the JP database)
• Re:ZERO -Starting Life in Another World- (UE24BT) , September 18, 2026, released
• Attack on Titan Vol. 2 (UEX07BT) , September 18, 2026, released

That is twelve 2026 booster releases through September 18. The confirmed schedule already runs into May 2027; see the next section.

Re:ZERO and Attack on Titan Vol. 2 after launch

Both releases became available on September 18, 2026. The first post-launch signal is real public list activity, but it is not yet a verified tournament ranking.

• Re:ZERO: Union Arena Decklists now shows 877 hosted 50-card lists that play at least one UE24BT card, most of them Re:ZERO. Rem leads at 38% (331 lists), then Emilia at 33% (293), Beatrice at 14% (124) and Crusch at 9.2% (81). The site's slice is a character-representation signal, not a win rate.
• Attack on Titan Vol. 2: the original set and Vol. 2 share one title, so public list counts mix both. The video below walks through the Vol. 2 decks one by one.
• Tournament evidence: Bandai's Top-Placing Decks archive was last updated with a September 18, 2026 reveal from the Championship 26-27 Offline Regionals Wave 2 at 401 Games: Solo Leveling took 1st, 2nd and 4th, and Evangelion took 3rd. No Re:ZERO or Attack on Titan Vol. 2 list has an official placement yet, so use the counts above to choose a test shell, not to label a winner.

The Ram deck guide and Mikasa deck guide go deeper on the two focal-character shells now being tested. The combined post-launch tier refresh keeps those public lists separate from verified tournament results, so a fast release cadence does not turn list volume into a made-up competitive result.

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:

• Bleach , one of the two launch IPs (booster released October 4, 2024), with Vol. 2 on May 30, 2025 and Vol. 3 due November 13, 2026.
• Jujutsu Kaisen , the third English booster (November 22, 2024), with Vol. 2 on June 27, 2025. Our Union Arena JJK guide covers the Domain Expansion mechanic and top decklists.
• Solo Leveling , the IP with the most recent official wins: first at the GENCON regional (revealed August 21, 2026) and first, second and fourth at 401 Games (revealed September 18). 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

Re:ZERO (UE24BT) and Attack on Titan Vol. 2 (UEX07BT) released September 18, 2026 and are the most recent EN booster releases as of this update. See our Union Arena InuYasha English release guide for the previous launch's set details, and the post-launch guides above for the two newest IPs. Bandai has published a confirmed schedule running well past them:

• 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
• Puella Magi Madoka Magica , April 30, 2027
• Mushoku Tensei: Jobless Reincarnation , May 21, 2027

Mushoku Tensei (UE30BT) was added to the products page on September 18, 2026, eight months before its May 21, 2027 date, so new titles can appear well ahead of release; watch the official Union Arena EN channels for anything after May 2027.

Dragon Ball in English is primarily the separate Fusion World game, not Union Arena; the official EN products page does not list a Dragon Ball Union Arena set through its current May 2027 schedule, checked October 8, 2026.

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

Which Set Should You Buy?

• Beginners: Solo Leveling is a clear starting point; for the newest releases, compare the public-list evidence for Re:ZERO and Attack on Titan before buying a full shell.
• Competitive: use the official recommended and top-placing deck lists, since standings can change as new sets release.
• Collectors: pick the IP you love, that is the whole appeal of the multi-IP model, or compare sealed and singles prices for the latest release.

What Union Arena players say about the schedule

Players on r/Union_Arena_TCG describe the same pattern this list shows. In a July 2026 release schedule thread, one player wrote: "As for the release schedule, we get news kinda randomly about that. Also, usually, an IP gets one set and it's done." Another added that "the best you get is vol 2 and potentially vol 3 which is an expansion of base sets".

Our take

This take is based only on the official products page, card list and top-placing archive cited here. Union Arena's English line has released 31 booster-type sets in two years and already lists nine more products through May 2027, so no one can collect or play all of it. Pick one title you like, check whether it has a Vol. 2 or Vol. 3, and use the official top-placing archive rather than release hype to judge competitive strength.

Frequently Asked Questions

Does Union Arena have a championship series? Yes. The official site lists a Championship 26-27 season with Offline Regionals, and its Top-Placing Decks page posts the winning lists. Check the events page for the current schedule.

Can I put two anime titles in one Union Arena deck? No. The official beginner page says a deck is 50 cards belonging to the same series, and that cards from different series cannot be included in the same deck.

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.
