Arcana Heart[b] is a 2006 fighting arcade game originally developed by Yuki Enterprise and published by Atrativa Japan.

Its gameplay consists of one-on-one fights, with a main four-button configuration, featuring special and super techniques, as well as four playable modes.

In 2007, Examu released a single custom chip patch for arcades titled Arcana Heart Full!, which introduced a number of fixes and balances.

Arcana Heart garnered positive reception from critics since its release on PlayStation 2; praise was given to the hand-drawn graphics, character roster, gameplay, and multiplayer but criticism was geared towards the high learning curve and complexity for newcomers, lack of additional content, and balancing issues in the single-player modes, with some feeling divided in regards to the sound design.

Arcana Heart is a airborne-based fighting game reminiscent of Asuka 120% Limited Burning Fest and Guilty Gear.
