Sword Girls is a (mostly) free Card Battle Game. It originates from Korea, while its English version is currently in open beta. The game's setting is a world with an Improbably-Female Cast. There are four factions: Vita, a high school; the Royal Academy, a private school for aristocrat girls, and their maids; Crux, a theocratic country; and Darklore, a catchall name for dark forces rejected by Crux, including vampires, Heretics and witches. The game's backstory is mostly pieced together from the flavor texts of cards. The game is also filled with truckloads of Fan Service.
