Holy (ホーリー Hōrī), sometimes dubbed as "Pearl" or "Faith," is a technique introduced in Kingdom Hearts: Chain of Memories. It typically allows the user to attack foes with one or more pillars of light.
Mechanics
In Kingdom Hearts: Chain of Memories, Holy is a Magic Sleight. It summons a pillar of light around the user, then summons three more sequentially beneath targeted enemies. The pillars have a wide radius, and can damage several enemies at once if they are close together. Its card combination is:

In Kingdom Hearts II, Faith is a Reaction Command usable when Sora is escorting Queen Minnie. When used, Queen Minnie summons a large pillar of light under her and Sora, damaging and knocking away nearby Heartless. King Mickey also has a variation of Holy called Pearl in which he shoots a ball of light at the opponent. He uses Pearl during battles when Sora is defeated.
In Kingdom Hearts 358/2 Days, Holy is the King's Limit Break. It allows him to summon pillars of light that can be charged with 
for more power. His Final Limit allows him to charge it further to summon a triangular formation of four large pillars of light, as well as orbiting orbs of light that fly outwards from the center.
In Kingdom Hearts Birth By Sleep, Faith is an Ultimate magic command exclusive to Ventus that summons pillars of light in a circle around the user, then expels them outwards to damage enemies and restore the user's health. It takes up two slots in the Command Deck, has a maximum level of 6, has a normal reload time of 25 seconds, and fills the Command Gauge by 20%.
In Kingdom Hearts Re:coded, Faith is a Type A Finish command used by Data-Sora. It allows the user to summon pillars of light that repeatedly hit targeted enemies.
In Kingdom Hearts 3D: Dream Drop Distance, Faith is a magic command exclusive to Sora that allows the user to summon a circle of light pillars that spin outwards, dealing light damage. It also restores a small amount of HP as a Cure-based technique, and can therefore be enhanced by equipping Cure Boost. Faith uses two slots in the Command Deck and has a reload time of 40 seconds. It grants +4 to Magic and +30 to Light Resistance when attached to a Dream Eater recipe.
In Kingdom Hearts χ, Holy and Holy+ are card techniques that are exclusive to SR+ cards and hit the enemy twelve times.
