Esuna (エスナ Esuna?) is a technique that appears in Kingdom Hearts Birth by Sleep, Kingdom Hearts Birth by Sleep Final Mix, and Kingdom Hearts Re:coded. It allows the user to remove all negative status effects. When used, small orange orbs appear around the player character and move down and then up the character, during this the character emits an orange aura and the spell takes effect. In Re:coded, the light is instead bluish and lacks the orbs, in addition to the spell healing you slightly. The technique is named after the spell under the same name in the Final Fantasy series.
In Kingdom Hearts Birth by Sleep, Esuna is an Advanced Magic Command that takes up one slot in the Command Deck and has a normal reload time of 15 seconds.
- Terra, Ventus, and Aqua can purchase Esuna from the Command Shop for 600 munny once five worlds are cleared or the command has already been obtained elsewhere.
