What is the English name of BT09?
Gemblo has not announced an official English name. We list it as Storm Passes, Clear Sky, the English title used for the Blue Archive event story that carries the same Chinese-character name, 嵐過天晴. Other sellers list the same box as The Calm After the Storm or as Ram & Cheoncheon, a romanization that reads the middle character as the Korean word for "and". All of these refer to this BT09 box.
Can I use Blue Archive cards with my other Nivel Arena cards?
A Nivel Arena deck is built from a single franchise, so Blue Archive cards go in a Blue Archive deck. That deck can play against decks from the other franchises in the game, such as Goddess of Victory: NIKKE, Brown Dust 2 or Eternal Return.
Which language are the cards printed in?
This is the Korean edition from Gemblo Company. Card names and card text are printed in Korean. Nivel Arena has no official English release.
Is this Union Arena?
No. Bandai's Union Arena also has Blue Archive cards, but that is a different game with different rules. BT09 is a Nivel Arena set and does not mix with Union Arena cards.
