Fukka Shourai (Wind flower: Summoning) is one of Syaoran Li's attack spells, using his Ceremonial Jian, and a wind Jufu. It can be used to create whirlwinds as barriers or to allow for brief levitation.
"Obey the command! Wind Flower, Come Forth!"
In the English-dub the phrase is shortened to "Element: Wind!" in order to match the animation's lip-flaps.
Tsubasa Reservoir Chronicles
Unlike his counterpart, Tsubasa Li doesn't use the paper charms, he simply uses his two fingertips to summon the spell.
