Union Arena Madoka Magica Set Announced: UE29BT 2027

Union Arena Madoka Magica is officially on the release calendar. Bandai's product page confirms the set, UE29BT, based on Puella Magi Madoka Magica, releases April 30, 2027, making it the first mahou shoujo (magical girl) license in the game's card pool.

What Happened

Bandai's official Union Arena site listed a new booster pack, UE29BT, Puella Magi Madoka Magica, in its September 10, 2026 product update. The confirmed details are limited but specific: an April 30, 2027 release date, a Release Event window running April 30 through May 6, 2027, and an MSRP of $4.99 per 12-card pack. The pack configuration matches Union Arena's standard structure, 16 packs per display box and 16 display boxes per case.

Beyond those logistics, almost nothing else is confirmed yet. The product page's artwork is still a "Now Designing" placeholder, and the official card list search returns zero results for the set as of this writing. No characters, no card text, no rarity breakdown, and no box art have been shown.

Why It Matters

Madoka Magica is a genuinely new kind of license for Union Arena. The game's existing catalog leans heavily on shonen action franchises (Bleach, Jujutsu Kaisen, Hunter x Hunter) with a scattering of other genres (Sword Art Online, Re:ZERO, Solo Leveling), but nothing in the mahou shoujo space. That's a real gap in the pool, and Madoka Magica is one of the most recognizable, highest-profile titles that genre has to offer, a reasonable pick if Bandai is looking to diversify who the game's card pool appeals to rather than adding another action series to an already-crowded lane.

The April 2027 release date also matters for pacing. Union Arena has released a new single-IP set at a near-monthly clip since its 2024 launch, and this confirms the pipeline extends at least that far into next year without a visible gap. For collectors and competitive players alike, the practical takeaway right now is patience: with zero cards revealed and over seven months before release, there's nothing yet to build around, price-check, or speculate on with any real confidence. The set is worth bookmarking, not acting on.
