Intro Yui (ユイ, Yui?), officially named «Yui-MHCP001» (Mental Health Counseling Program 001), is a supporting character throughout the Sword Art Online series. She is a top-down Artificial Intelligence (AI) program that was originally developed by Argus to address player mental health concerns in Sword Art Online (SAO). However, when Kayaba Akihiko turned Sword Art Online into a death game, Yui was forbidden from interfering with players whatsoever by the Cardinal System, which led to her collapsing due to being forced to monitor player mental health without being able to fulfil her duties. Found in this broken state by Asuna and Kirito around the forests of the 22nd Floor of the floating castle Aincrad, she was mistaken for a lost child player and adopted by the couple. Yui had become melancholic when the death game began, as she was not allowed to comfort players and was forced to continue monitoring their psychological parameters. When she finally, after nearly two years of only seeing insanity, misery, and anger, noticed a couple, expressing happiness and joy, she became overwhelmed with curiosity, which led to her ignoring the Cardinal System's command not to interact with players. As her memory became corrupted, Yui's behaviour regressed to that of a child. She became cheerful when Asuna and Kirito pretended to be her parents, but she also showed signs of obstination, such as refusing to stay with Sasha when Asuna and Kirito decided to go to a hidden dungeon to rescue Thinker. in the crossover world Yui didn't know what happened to her parents Kirito and Asuna she didn't know they were corrupted and depression all she can think about is everything just fine until her adopted Uncle Sumba takes very good care of Yui while they're gone but they never come back. and she trained to be a strong swordswomen to be stronger like Kirito.
