However, angry at Kirito, he attacks her with intentions of raping and eventually killing her, revealing himself to be Death Gun's creator. Shino manages to resist his attack and escape, but is stopped by Kyōji before she could exit the house; Kirito arrives and fights Kyōji, the latter eventually being knocked out by Shino throwing her stereo at him. After the Death Gun incident, Sinon seems to have gotten over her fear and is moving on from the incident, no longer vulnerable to her classmates' threats of using a gun on her. In Agil's café, Shino meets Asuna, Rika, and Sachie Osawa, a woman who had survived the post office incident, who convinces her that she had saved her and her daughter's life. Sinon eventually decides to play "ALfheim Online" with Kirito and his friends. During her time with Kirito, Sinon develops romantic feelings for him, but decides not to pursue them due to her close friendship with his girlfriend, Asuna. However, she does on occasion, show Kirito her true feelings for him. Originally a side-story character in SAO, Yui later becomes an accompanying/support character in ALO. At first thought to be a lost child in SAO, she is an artificial intelligence. Her full designation is «Mental Health – Counselling Program», MHCP version 1, codename, «Yui». Yui is shown to have a human form and a Navigation Pixie form where she is always barefoot in both forms. She was designed to monitor the emotions of players and appear at their sides to hear and help them out. However, since the moment everyone was imprisoned in Sword Art Online, she was forbidden to come in contact with the players and complete her prime directive. Unable to do anything but suffer as she monitored the emotions of the trapped players, she came upon Kirito and Asuna whose emotions stood out as a beacon of joy and peace in a sea of fear and despair. She sought them out, appearing to them as an amnesiac child whom they adopted. In the end she was nearly deleted by Cardinal, the management system of SAO, but is saved by Kirito by converting and storing her data into his own NerveGear. Yui later shows up in ALO as a Private Navigation Pixie and helps Kirito along with Leafa to find Asuna. She refers to Kirito as "Daddy" and Asuna as "Mommy" and gets very annoyed if any girl other than Asuna, Leafa or Sinon gets close to Kirito.
