Tozawa Misumi was a student at the Aeterna Girls' Academy, where she befriended her classmate Yuuki Asuna. Being one of the 1,000 beta testers for Sword Art Online, Misumi encouraged Asuna to play the game with her in the official release. On November 6, 2022, Misumi became one of the 10,000 players trapped in the public release version «Sword Art Online» and temporarily formed a party with Asuna.
Until an accident in the field led her to believe that Asuna had been killed by monsters. Since then, Misumi became one of the Clearers to help defeat the game's bosses in order to beat the game.
