On May 8, 2026, Saitou approached Yui with his fairy avatar and confessed his love to her, before stating he would be retiring from the game soon. When Yui told him that she would not allow him to monopolise her, he claimed that he would be retiring from the game soon, thus he had only wanted to speak with her before doing so.
The baffled Yui, ended up hacking the server for his real life address, as the player had already deleted his account in the game, and went with Asuna to find him. They eventually found out that he was an old man who had passed away several days before they arrived.
