Limelight is a lightning-based technique that is used when all four users take place in the cardinal directions. They will then join their lightning-chakra in the form of four connecting streams that shoot high into the sky above the target area. It will then create a massive ball of lightning powerful enough to incinerate everything within the area of the four users. It is considered to be the most powerful and destructive Lightning Release technique.[1]

Trivia

The technique's name is a pun, similar to certain techniques of Kumogakure-ninja, in which it has an English name with a given kanji that somewhat matches the pronunciation.
