What Is UNION ARENA?
UNION ARENA is a crossover trading card game (TCG) developed by Bandai that allows players to build decks using characters from a wide range of popular anime, manga, and gaming franchises. The game successfully combines accessible, easy-to-learn gameplay with high-quality collectible cards featuring officially licensed, exclusive artwork.

The game has rapidly expanded its catalog with titles from some of the biggest names in anime, and The 100 Girlfriends is the newest franchise to join the English lineup.
