Kirito had grown quite tech-savy over the years and he decided how to give Asuna a present he knew she'd love. Even though it was only a hologram, Yui would be able to be with them. It had been years since Sword Art Online but he knew how to get her back. He was going to do it that night at dinner with their friends from the game. Before Asuna came out into the living room, he had Lizbeth and Silica go and help her get ready, also to keep her busy for a while.

About 10 minutes later, Yui had also joined the party. She had just enough time to greet everyone else before she saw Asuna come out
"Mommy!!" Yelled Yui
"Yui!" Yelled Asuna and they gave each other a hug. Even though she was holographic everyone could sense the love that Yui had brought with her.
