Biography
When Kirito and friends first arrived on the beta opening of Ainground, the setting world of Sword Art: Origin, Kirito is the first to see Premiere shortly before logging off for the day. He sees her among the other players still in town and, when trying to reach out to her, disappears into the crowd before Kirito receives his mysterious message.

The next day, Kirito meets Premiere again and discovers she is a quest giving NPC. However, after partaking her quest of bringing her out of town, he receives only 1 Col after completion. It's then, with help from Seven in the real world, that he discovers Premiere is a NPC who has no original coding telling her how to act. After the others catch onto Premiere's strange condition, she is given her name "Premiere" from them. Later on, when Asuna and Kirito would take her quest again, they stumble upon a cave with a mysterious glowing stone that reacts when Premiere touches it, possibly believing it to be a part of her true quest.

After exploring the second area, Kirito is called back to town by Argo and realizes a shocking truth: Players in-game have been trying to kill the NPC characters (those of which cannot respawn in Ainground before being replaced by the system), believing a lie that they would get great rewards from it. Realizing Premiere was in danger, the two rush through town to find her. They manage to stop another player from killing Premiere, telling him that his new "blue cursor" causes monsters to solely target them and the NPC to act hostile towards them. Afterwards, Kirito asks Premiere to let him protect her, something she agrees to.
