Arcana Heart (アルカナハート, Arukana Hāto) is a 2D arcade fighting game developed by Examu Inc. (formerly Yuki Enterprise). The first edition was released to arcades (mostly in Japan, but a few in other countries) in late 2006. The game features an original all-female cast (each a variation of the moe archetype), and after choosing a character, the player chooses an "elemental alignment," or Arcana, which determines the character's special moves.
