Two New Booster Displays Arriving October 31, 2025!

Get ready, anime and TCG fans—The Hidden Lair in Mt. Zion, IL is about to become the battleground for two incredible new Union Arena expansions! Arriving October 31, 2025, players will be able to dive into the worlds of Yu Yu Hakusho: Ghost Files and Kaiju No. 8, two powerhouse franchises joining Bandai’s fast-growing Union Arena Trading Card Game. Whether you’re a nostalgic fan of classic shonen anime or a follower of modern manga sensations, these new sets promise action, strategy, and collectibility in equal measure.

Union Arena: A Growing Universe of Anime Battles

The Union Arena TCG has quickly built a name for itself as the ultimate crossover experience, letting players build decks from their favorite anime worlds and pit them against each other in tactical card combat. With franchises like Jujutsu Kaisen, Demon Slayer, Code Geass, and Hunter x Hunter already represented, each new release expands the roster and deepens gameplay variety.

The system’s accessible mechanics, colorful art, and faithful anime adaptations have drawn in both competitive players and collectors alike. Each booster display typically contains 16 packs loaded with vibrant character cards, signature attacks, and unique abilities—making every box a treasure chest for anime fans.

Now, two more worlds are about to collide in Union Arena form.

Yu Yu Hakusho: Ghost Files Booster Display (UE13BT)

Release Date: October 31, 2025
Publisher: Bandai Co., Ltd.

Few anime command as much nostalgic love as Yu Yu Hakusho. First airing in the early 1990s, it helped define the shonen battle genre—long before the days of Naruto or Bleach. With this Ghost Files expansion, Union Arena invites players to relive Yusuke Urameshi’s journey as a Spirit Detective battling demons, rival fighters, and otherworldly threats.

Expect to see iconic faces like:

• Yusuke Urameshi, the Spirit Detective with a heart (and punch) of gold

• Kazuma Kuwabara, the loyal brawler whose spirit sword never quits

• Kurama, the cunning fox spirit with deadly plants

• Hiei, the speed demon wielding the Dragon of the Darkness Flame

This set celebrates the anime’s mix of heart, humor, and hard-hitting combat. Fans can look forward to thematic card abilities that echo key battles from the Dark Tournament, as well as collector’s foil cards featuring classic artwork. For fans who grew up watching Toonami, this set is pure nostalgia sealed in booster packs.

Kaiju No. 8 Booster Display

Release Date: October 31, 2025
Publisher: Bandai Co., Ltd.

If Yu Yu Hakusho is the past, Kaiju No. 8 represents the thrilling future of shonen action. Set in a world besieged by giant monsters, this hit manga-turned-anime follows Kafka Hibino, an everyman who gains the power of a kaiju himself. Now, both humanity’s defenders and their monstrous foes stomp onto the Union Arena stage.

Players can expect decks featuring members of the Defense Force, led by the sharp-eyed Mina Ashiro, and kaiju units embodying the raw destructive force of the series. With the introduction of new mechanics representing kaiju transformation and evolution, this set promises dynamic, cinematic battles.

Beyond gameplay, the Kaiju No. 8 expansion also brings stunning visuals—Bandai has done justice to the anime’s bold design and intense action sequences. Collectors will want to chase the high-rarity holo cards featuring full-art versions of Kafka’s kaiju form and other breathtaking illustrations.
