Lightning (稲妻) is a spell that uses magic to perceive information that can be recognized and directly used without intervention from the brain and nervous system in order to directly move the body and spirit. 
Rather than having an inherited magic, Lightning was acquired through Airi's own efforts. 
Although there is a lag time between the use of a CAD, the body moves before even the magic is seen, making it one of the quickest magics around. 
- Lightning is the English name for the French word Éclair "エクレール".
