Asuna was finally free to reunite with her husband, or was she? Kayaba had told her Kirito was waiting for her "among the clouds." Certainly this couldn't be what he meant!
Sugu was a woman in pieces. Two years had passed since her brother's death. Two years of grief and hard-fought healing. All of it shattered in the span of seconds when the people who remained in SAO were finally free, reminding her of all she'd lost. Now she fruitlessly flew in ALO, hoping to find that inner peace she had once again lost.
