Lilith and Liana were fighting Hela the Goddess of death when suddenly Liana was stabbed and when Lilith held Liana in her arms she told her to stay safe and stay with her husband Kirito and her daughter Yui and live in and fight till the end of the game and then she disappeared in her arms Lilith cried for her sister and that's when Kirito walked up to her and put a gentle hand on her shoulder.

"Lilith...it's okay...Liana would want you to be strong. Not grief over her like this."

Kirito says, his voice soft, serious but also sympathy for her.
