|~ Shuyin to Yuna, thinking she is Lenne.|
Shuyin is the main antagonist and the final boss of Final Fantasy X-2.
A tormented spirit from Zanarkand a thousand years ago, Shuyin attempted to activate Bevelle's ultimate machina Vegnagun to end the war between Zanarkand and Bevelle before his lover Lenne was forced to fight.
The both of them killed, Shuyin remained as an Unsent, his grief and hatred twisting his mind, and he came to desire to use Vegnagun to destroy all of Spira and end humanity's constant fighting and struggles.
Fought deep in the Farplane after destroying Vegnagun, the Gullwings defeat Shuyin, and Lenne's spirit appears to him to soothe him and finally allow him to rest in peace.
