SAO:R is a creative fan story like no other, about a new set of experiments Rath is performing with the fluctlight technology. A few "instances" of digital history have been recreated from Kirito's fluctlight data and the data of other people who have dived into the Underworld or lived in it, and they have created artificial alternate universes in the same style as the Underworld itself. One of these instances' Kirito has died unexpectedly, and Kikuoka calls in the REAL Kirito to fill in and continue where his other self left off. Unfortunately, things get complicated as usual. Not only does the world he's diving into have another Alice, but she's the mother of two children, who happen to be Kirito's! Additionally, strange occurances are causing havoc despite Higa's best efforts. But that's not the only mess this whole AU project has caused in VR... it gets much worse... Originally created by me and BlueRoseKnight, along with Jean (visual artist), Seiren (cover artist) and Monica (assistant writer) of Vorpal Blade Productions, I seek to bring you something new; taking visual queues from the Alicization anime as well as Light Novel quality writing and a remixed opening cinematic to present what may be one of the most compelling SAO fanfictions to date. This is Sword Art Online: Reinitialization.

Después de ser atacado por un antiguo enemigo, Kirito es transportado a un mundo desconocido. En él, descubrirá los secretos detrás de la misteriosa organización RATH, mientras se vincula cada vez más con una persona de ese mundo.
