Union Arena
Union Arena 100 Girlfriends launches in English on July 10, 2026. The set brings Rentaro Aijo and the 6 main girlfriend characters from Season 1 of the anime to the card game with one of the most collector-intensive builds in recent Union Arena EN history: voice actor autograph SR parallels, serial-numbered AP cards signed by the original cast, connected illustration cards, and box toppers that vary per display.
TL;DR: Union Arena 100 Girlfriends (UE21BT) launches EN on July 10, 2026. It has 82 card types and 12 AP serial-numbered autograph parallels. Booster boxes are $79.99 for 16 packs. Chase: voice actor autograph SR parallels and two connected illustration cards that form a single linked image. Box toppers: one per display, 12 designs total (6 foil, 6 gold foil). 88 Cardhouse pre-orders sold out; stock remained at Flipside Gaming and ToyWiz.
Union Arena 100 Girlfriends (UE21BT) is the July 10, 2026 EN booster set featuring the cast of The 100 Girlfriends Who Really Really Really Really Really Love You. It has 82 standard card types and 12 AP cards, which are individual autograph parallels with serial numbers hand-signed by the Japanese voice actresses playing the 6 main girlfriend characters. Each display box includes 16 packs plus one random box topper from 12 available designs.
This is a collector-heavy set by any measure. The combination of AP serial cards, autograph SR parallels, connected illustration cards, and a per-box topper system makes UE21BT one of the more feature-dense releases in the EN Union Arena catalog.
New to Union Arena? The Union Arena TCG beginner guide covers how the game works before you commit to a specific IP set.
The anime follows Rentaro Aijo, a high school student with a streak of romantic rejections so extreme that the gods of love intervene. Rather than granting him one soulmate, they assign him 100 fated girlfriends, each of whom will die of heartbreak if he rejects her. The series plays the premise as romantic comedy chaos: each girlfriend is a hyperbolized character type, Rentaro genuinely cares for all of them, and the situations escalate quickly.
That premise translates cleanly to the card game. Each of the 6 main girlfriend characters (Hakari, Karane, Shizuka, Nano, Kusuri, and Hahari) has a distinct visual style and personality, which means differentiated card art and distinct ability design rather than palette-swapped variants. Rentaro is the central deck piece, but the girlfriend characters are where the strategy lives.
The second season wrapped in 2025, so EN players arrive with more character familiarity than most Union Arena IP sets get at launch. That's genuinely useful when you're making singles decisions.
The 100 Girlfriends Season 2 aired in 2024-2025, meaning EN players already know the full girlfriend roster when UE21BT launches.
The standard pool in UE21BT is 82 card types across Union Arena's rarity tiers. That's a tighter pool than InuYasha's roughly 130-card set, reflecting a focus on the core girlfriend roster rather than a deep supporting cast across multiple anime arcs.
Above the standard pool sit 12 AP cards. Each AP card is an autograph parallel of a girlfriend character's card, signed by her Japanese voice actress, with a unique serial number on each copy. With 12 AP card types across 6 characters, most girlfriends have more than one AP target for collectors to chase.
AP cards aren't functional upgrades over their base SR equivalents. They play identically in competitive decks. The distinction is physical: the autograph, the serial number, the altered art. Pull rates are low. Most buyers won't see an AP card from a single display box.
For a full breakdown of how AP parallels compare to other Union Arena rarity tiers from Common through Special Rare, the guide below has the complete picture.
GODEEPER: AP cards sit above Special Rares in pull rarity and collector value. Here's how every Union Arena rarity tier works and what each one means for deck building versus collecting. Union Arena Card Rarities Explained →
Within the standard pull spectrum, the primary collector targets are SR parallels with voice actor autographs. These are alternate versions of existing SR cards where the card artwork carries a printed-on autograph from the character's Japanese voice actress.
Each autograph SR exists in multiple variant tiers, similar to the two-star and three-star autograph variants in the InuYasha set. The base autograph SR is the more accessible version; the premium variant has additional art or finish treatment with significantly lower pull rates. Six voice actress autographs cover the core girlfriend lineup in UE21BT.
Competitive players should note: autograph SR parallels and their base SR counterparts are the same card for gameplay. If you're building a Union Arena 100 Girlfriends deck for tournament play, the standard SR is the piece you need. The autograph version is a collector upgrade, not a power upgrade.
The six main girlfriend characters each have voice actress autograph SR parallels in UE21BT. The inline card art reflects each character's distinct visual identity.
Two cards in UE21BT form a connected illustration. When placed side by side, their artwork combines into a single wide image spanning both cards. Completing this pair requires both cards individually, either from pulls or singles purchases. Since both are mid-rarity chase cards rather than commons, most players need to target them on the secondary market to get both.
The box topper system is the other notable structural feature. Every display box includes one box topper card, randomly drawn from 12 designs. Six designs use standard foil treatment; six use a gold foil treatment that tends to carry a premium.
Because box toppers are guaranteed per box (one per display, always), they don't enter the secondary market the same way booster pull cards do. You can plan for one topper per box, and if you need a specific character's design, trading or singles purchasing after launch is more reliable than opening until you hit it.
Define your goal first. Collector goals and competitive goals lead to different purchase paths. Knowing which one you're after before spending prevents the most common regret in TCG launches.
For competitive play: wait two weeks. UE21BT has no JP tournament reference data because it's an EN-first release. The first EN tournament results will establish which cards are genuinely playable and which overhyped at launch. Buying singles two weeks in costs more than pre-ordering boxes but costs less than buying the wrong things at launch prices.
For collector targets: check singles on launch day. AP card prices establish within 24 to 48 hours of launch. If a specific girlfriend's AP card is your target, the singles market on launch day often has more predictable pricing than it does a week later when the hype window drives speculation up.
For box openings: confirm stock before purchasing. 88 Cardhouse sold out before launch. Flipside Gaming and ToyWiz had stock at release. Call or check the site directly for your preferred retailer rather than assuming availability.
For the connected illustration: target singles directly. The two connected illustration cards are the hardest to pull as a pair from boxes. Plan to acquire them on the singles market after EN prices settle rather than pulling toward them.
If you're chasing a specific AP card, buy it on the secondary market rather than pulling for it. AP prices peak in the first week and compress by week three as more sealed product hits the market. Gold foil box toppers will probably hold value longer than the standard foil versions since the print count is identical but the perceived premium is real.
If you're playing competitively, the first week of EN results matters more than anything else here. Don't lock in on singles in the first 48 hours. Watch the first local tournament reports and adjust. Rentaro as the central leader card is a safe early buy; support card value varies a lot based on how the meta actually shakes out.
If budget is the concern, most competitive Union Arena builds don't require the autograph SR versions at all. The Union Arena deck building guide covers how to build a competitive 50-card deck without chasing the collector tier.
GODEEPER: The InuYasha EN launch in August 2026 follows the same format: autograph SRs, a connected illustration pair, and pre-order sellouts. Here's how the InuYasha launch played out and what it tells you about how to approach EN launch sets. Union Arena InuYasha English Release Guide →
Pack MSRP is $4.99. Display box MSRP is $79.99 for 16 packs. The 88 Cardhouse sellout during pre-orders is worth noting: EN players moved faster on this IP than on most recent Union Arena releases.
When does Union Arena 100 Girlfriends release in English? July 10, 2026. The set code is UE21BT. Pre-orders at 88 Cardhouse sold out before the launch window, a strong early signal of EN demand for this IP compared to recent Union Arena sets.
What is UE21BT in Union Arena? UE21BT is the English product code for the Union Arena 100 Girlfriends set. It has 82 standard card types plus 12 AP autograph parallel cards, for a total of 94 card types including the autograph tier.
What are AP cards in Union Arena 100 Girlfriends? AP cards are individually hand-signed autograph parallels with unique serial numbers. There are 12 AP card types in UE21BT, spread across the 6 main girlfriend characters, each signed by her Japanese voice actress. They're the rarest pulls in the set and don't offer any gameplay advantage over the base SR versions.
What are the chase cards in UE21BT? Voice actor autograph SR parallels are the primary collector targets within the standard pull range. Two cards form a connected illustration that only reveals the full image when both are displayed side by side. AP serial-numbered cards are the rarest pull tier.
How much does a box cost? Display boxes are $79.99 MSRP for 16 packs. Individual packs are $4.99 each at MSRP.
Where can I buy Union Arena 100 Girlfriends? Flipside Gaming, ToyWiz, and vgmx.com had launch stock. 88 Cardhouse pre-orders sold out before release. Local game stores with Union Arena distribution are worth checking directly.
Is 100 Girlfriends good for competitive Union Arena? Too early to say definitively. UE21BT is an EN-first release with no JP competitive reference data. The set design skews collector-heavy, but EN tournament results in the first two to three weeks after July 10 will establish the actual competitive viability of each card.
