During Shards 3 Event Airu was replaced by Dark Airu, which appeared in Gambits long before that once or twice. But this Gambit had nothing about her. So don't expect something about Kurito this time. Though, Kurito does appear on several cards found on http://www.outofstandard.jp/peropero/card.php I've posted them a few times, but now just don't feel like going through all this database once again looking for them. Try doing that yourself if you are so interested. They should be in N Rarity section, as far as i remember...
