Kachousen

Kachousen (lit. Butterfly Folding Fan) is one of the signature moves of Mai Shiranui, making its initial appearance in the Fatal Fury series and being a part of her moveset in every game ever since.

Description
Mai throws her fan at her opponent.

Starting with The King of Fighters XIII, Kachousen gained an EX Special Move variant. In KOF XV, the version bounces the fan up and down after the first hit.

Strategy
Although it's Mai's only projectile, its main purpose is usually not for zoning, but rather space control.
