THE GRAND QUEST
Yui senses Asuna's player ID. Upon hearing from Yui that Asuna is at the top of the World Tree, Kirito can hold back no longer, and spreads his wings.
But he is blocked by a system barrier, and fails to reach even the lowest branch.
But Asuna herself is also aware that they're there.
Asuna throws a certain item into the sky, pouring all of her hopes into it. Armed with a fresh resolve to get Asuna back, Kirito decides to take on the challenge of the impregnable Grand Quest - the only path leading to the top of the World Tree.
