Premiere (プレミア, Puremia?) is a game adaptation-original character in Sword Art Online: Hollow Realization. Unlike the other main characters, she is a Non-Player Character (NPC), born from the creation of Sword Art: Origin. Premiere looks almost identical to her sister Tia, the only identifying difference between the twins being the presence of a small mole right under the corner of the former's right eye. Like Tia, Premiere has blue eyes and short black hair, with two dull gold decorations around the forelocks framing her face. Her outfit consists of a light blue-green shirt and a white skirt with light purple edging that exposes much of her legs above and below the knees. The shirt and skirt are connected to light purple sleeves that cover her wrists and the back of her hands, which in turn are covered with a set of wide sleeves of the same color as her shirt. Additionally, over her shirt she has four dark blue-green and light purple strips of cloth, reminiscent of religious clothing, that are attached by three dull gold buckles on the front to each other, and a white collar covering her shoulders and part of her neck. She wears brown leather sandals covering her toes and heels that leave the sides of her feet exposed, with a circular leather strip wrapped above her ankles, and a silver metal decoration on the toe box. After requesting fighting lessons from Kirito, she began wielding a rapier. Originally, Premiere had no pre-programmed settings to determine her behavior or interactions with players. However, after meeting Kirito's group, she began to develop an inquisitive and childlike nature, often learning and utilizing words and phrases she heard from other players.

Sword Art Online
In 2022, a virtual reality massively multiplayer online role-playing game (VRMMORPG) called Sword Art Online (SAO) is released. With the NerveGear, a helmet that stimulates the user's five senses via their brain, players can experience and control their in-game characters with their minds. Both the game and the NerveGear was created by Akihiko Kayaba. On November 6, 10,000 players log into the SAO's mainframe cyberspace for the first time, only to discover that they are unable to log out. Kayaba appears and tells the players that they must beat all 100 floors of Aincrad, a steel castle which is the setting of SAO, if they wish to be free. Those who suffer in-game deaths or forcibly remove the NerveGear out-of-game will suffer real-life deaths. The main character, Kirigaya "Kirito" Kazuto, was also one of 1,000 testers in the game's previous closed beta. With the advantage of previous VR gaming experience and a drive to protect other beta testers from discrimination, he isolates himself from the greater group and plays the game alone, bearing the mantle of "beater", a "beta tester" and "cheater". As the players progress through the game Kirito eventually befriends a young girl named Asuna Yuuki, who form a relationship that later turns into in-game marriage. After the duo discover that Akihiko Kayaba was playing the game as the leader of the guild Asuna joined, they confront and destroy him, freeing themselves and the other players from the game.
