Sword Art Online (ソードアート・オンライン, Sōdo Āto Onrain) is one of the most influential Japanese multimedia franchises of the 21st century. Originally created as a light novel series by Reki Kawahara, with illustrations by abec, it has expanded into anime, films, manga, and video games.
The series began as a web novel (2002–2008) before being officially published in 2009 by ASCII Media Works’ Dengeki Bunko imprint. It follows the adventures of Kazuto “Kirito” Kirigaya and Asuna Yuuki, two players trapped in virtual reality MMORPGs where dying in-game means dying in real life.
Since its first anime adaptation by A-1 Pictures in 2012, Sword Art Online has become a global phenomenon, with light novels selling over 30 million copies worldwide, several hit anime seasons, multiple animated films, and an extensive catalog of video games. While praised for its animation, music, and exploration of VR psychology, it has also faced criticism for pacing and character writing.
