She rescues Mamoru Itsuki from the Underworld and destroys the seven gates so that no more yamibito can be released. She separates from Mamoru soon after, preferring a solitary path. She liberates the soul of Shigeru Fujita and reunites with Mamoru on top of the Spider's Thread. Working with him, they defeat Mother and escape back into the real world. She is the second true survivor of the game.
